Rhea-AI Filing Summary

Thunder Mountain Gold, Inc. reported a Q1 2026 net loss of $590,758, slightly higher than the $540,300 loss a year earlier, as it ramped up exploration and professional spending.

Operating expenses rose to $594,595, driven by exploration costs of $167,128 and higher legal and accounting fees, while stock-based compensation declined. The company ended the quarter with cash and cash equivalents of $1,813,057 and believes this is sufficient for at least the next twelve months, though it remains an exploration-stage company with an accumulated deficit of $11,220,236.

Strategically, Thunder Mountain advanced its South Mountain Project and broader Idaho footprint. It won mineral lease rights on about 3,500 acres of Idaho state land with a $210,000 bid plus initial rent and royalty payments, capitalized as mineral properties, and continued a funding and technical partnership with MFD Investment Holdings, which can earn a 10% project interest by contributing $1,000,000 in expenditures.

Preliminary Economic Analysis (PEA) financial
"baseline environmental and engineering work necessary to complete a Preliminary Economic Analysis (PEA)."
Stock Incentive Plan financial
"The Company has a Stock Incentive Plan (the "SIP"), that authorizes the granting of stock options"
A stock incentive plan is a company program that gives employees or directors pieces of ownership or the right to buy shares over time, similar to receiving a bonus paid in company stock instead of cash. Investors pay attention because these plans align staff incentives with long‑term company performance but can also dilute existing shareholders and affect reported profits when grants are expensed, so they influence both ownership percentages and financial results.
noncontrolling interest financial
"Noncontrolling interest in Owyhee Gold Trust (Note 3)"
The portion of a business owned by investors other than the controlling owner when one company has control of another; it represents outside shareholders’ share of the subsidiary’s assets and profits. For investors, it matters because those outside claims reduce the amount of profit and net assets attributable to the parent owner — similar to saying part of a pizza belongs to someone else — and thus affects earnings, book value and valuation.
going concern financial
"prepared under the assumption that the Company will continue as a going concern."
A going concern is a business that is expected to continue its operations and meet its obligations for the foreseeable future, rather than shutting down or selling off assets. This assumption matters to investors because it indicates stability and ongoing profitability, making the business a more reliable investment. Think of it as believing a restaurant will stay open and serve customers, rather than closing down suddenly.
Inferred Resources financial
"Inferred Resources have a great amount of uncertainty as to their existence and their economic and legal feasibility."
An inferred resource is an early-stage estimate of how much mineral or fuel may be present in the ground based on limited geological evidence and sampling. Think of it like seeing scattered clues that suggest a buried treasure might exist but not having dug enough to be sure; the potential size and value are uncertain. For investors it signals possible upside but carries high risk and should not be treated as proven supply or relied on for firm production plans.

In the opinion of management, all adjustments, consisting of only normal recurring adjustments, and disclosures necessary for the fair statement of these interim statements have been included. The results reported in these interim statements may not be indicative of the results which will be reported for the year ending December 31, 2026. The condensed consolidated December 31, 2025 balance sheet data was derived from audited consolidated financial statements.

Business Operations

Thunder Mountain Gold, Inc. ("Thunder Mountain", "THMG", or "the Company") was originally incorporated under the laws of the State of Idaho on November 9, 1935, under the name of Montgomery Mines, Inc.  In April 1978, the Montgomery Mines Corporation was obtained by a group of the Thunder Mountain property holders and changed its name to Thunder Mountain Gold, Inc., with the primary goal to further develop their holdings in the Thunder Mountain Mining District, located in Valley County, Idaho. Thunder Mountain Gold, Inc. takes its name from the Thunder Mountain Mining District, where its principal lode mining claims were located. For several years, the Company's activities were restricted to maintaining its property position and exploration activities. During 2005, the Company sold its holdings in the Thunder Mountain Mining District. During 2007, the Company acquired the South Mountain Mines property in southwest Idaho and initiated exploration activities on that property, which continue today.

Basis of Presentation and Going Concern

The accompanying consolidated financial statements have been prepared under the assumption that the Company will continue as a going concern. The Company has historically incurred losses, however, the Company has cash reserves sufficient to cover normal operating expenses for the following 12 months. If necessary, the Company continues to have the ability to raise additional capital in order to fund its future exploration and working capital requirements.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company; its wholly owned subsidiaries, Thunder Mountain Resources, Inc. ("TMRI") and South Mountain Mines, Inc. ("SMMI"); and a company in which the Company owns 75% and has majority control, Owyhee Gold Trust, LLC ("OGT").    The Company's consolidated financial statements reflect the other investor's 25% noncontrolling, capped interest in OGT.  Intercompany accounts are eliminated in consolidation.


Accounting Estimates

The preparation of the condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions include the carrying value of properties and mineral interests, environmental remediation liabilities, deferred tax assets, and stock-based compensation. Management's estimates and assumptions are based on historical experience and other assumptions believed to be reasonable under the circumstances. Actual results could differ from those estimates.

Recent Accounting Pronouncements

Accounting Standards Updates

In November 2024, the Financial Accounting Standards Board ("FASB") issued ASU 2024-03, Disaggregation of Income Statement Expenses (Subtopic 220-40). The standard requires public business entities to disclose additional information about certain expense categories included in income statement captions, including purchases of inventory, employee compensation, depreciation, depletion, and amortization. The amendments also require qualitative disclosures regarding other significant expense components included within the same income statement captions. The guidance is effective for annual reporting periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. The company is currently evaluating the impact of the standard on its consolidated financial statement disclosures. 

Net Income (Loss) Per Share

The Company is required to have dual presentation of basic earnings per share ("EPS") and diluted EPS. The Company calculates basic earnings (loss) per share by dividing net income or loss available to common stockholders by the weighted average number of common shares outstanding during the applicable reporting period. Diluted earnings per share reflect potentially dilutive common stock equivalents, including options and warrants that could share in our earnings through the conversion to common shares, except where their inclusion would be anti-dilutive. For the three months ended March 31, 2026 and 2025, outstanding warrants of 22,400,000 and 12,400,000, respectively, and outstanding stock options of 5,945,000 and 4,865,000, respectively, were excluded from the calculation of diluted earnings per share, as their effect would have been anti-dilutive due to the net loss for the periods.

 

2. Mineral Interest Commitments

The Company holds leases pertaining to land parcels adjacent to its South Mountain patented and unpatented mining claims. The details of these leases are as follows:

Lowry Lease:

On October 24, 2008, the Company executed a lease agreement with William and Nita Lowry for a duration of 6 years, encompassing 376 acres at a rate of $20 per acre. Following the passing of the original lessors, the lease was inherited by Michael Lowry, their son. On October 24, 2025, the Company entered into an extension of the lease agreement with Michael for an additional 21-year term through October 24, 2046. Under the amended agreement, annual lease payments are $40 per acre for the first seven-year period, $50 per acre for the second seven-year period, and $60 per acre for the final seven-year period.

Looten Lease:

On June 2, 2025, the Company executed a lease agreement with Kevin and Jo Looten for an initial term of 7 years, encompassing 18 acres at a rate of $30 per acre. The lease includes an option to extend for an additional 10 years at a revised rate of $40 per acre.

Lequerica & Sons Lease:

On August 22, 2025, the Company executed a lease agreement with Lequerica & Sons, Inc. covering 432 acres for an initial term of seven years at an annual rental rate of $30 per acre. The lease includes an option to extend for an additional seven years at a revised rate of $40 per acre. The agreement contains a right of first refusal in favor of the Company with respect to the underlying property in the event of a proposed sale by the lessor.

The leases have no work requirements. It is the current intention of the Company to engage in negotiations for new leases with the current landowners upon the expiration of the existing lease agreements. The negotiations may involve modifications to terms, rates, or other conditions as mutually agreed upon by the parties involved.

Idaho State Mineral Lease:

In March 2026, the Company was awarded mineral lease rights on approximately 3,500 acres of Idaho state land through a competitive auction process and submitted a winning bid of $210,000. In connection with the proposed lease, the Company also paid 2026 lease rent of $10,495 and a minimum annual royalty of $10,000.

As of March 31, 2026, the lease was subject to final approval by the Idaho State Land Board and had not yet been formally executed. Upon execution, the lease is expected to have a 20-year term and require ongoing annual lease payments and minimum royalty obligations to maintain the lease in good standing.

Unpatented Mining Claims:

The Company holds unpatented mining claims in the Trout Creek area in Nevada and the South Mountain Project in Idaho. The number of claims at the South Mountain Project increased significantly during 2025 as a result of additional claim staking activities.

The claim fees are paid on these unpatented claims annually as follows:

Target Area   2026  
Trout Creek - State of Nevada $ 5,200  
Trout Creek - Lander County, Nevada   324  
South Mountain - BLM   109,928  
Total $ 115,452  

 

3. South Mountain Project

SMMI Joint Venture - OGT, LLC

The Company's wholly owned subsidiary SMMI is the sole manager of the South Mountain Project in its entirety through a separate Mining Lease with Option to Purchase ("Lease Option") with the Company's majority-owned subsidiary OGT.  SMMI has an option to purchase the South Mountain mineral interest for a capped $5 million less net returns royalties paid through the date of exercise. The Lease Option expires in November 2026.  If SMMI exercises the option, the option payment of $5 million less advance royalties will be distributed 100% by OGT to OGT's minority member, ISGCII.  Under the Lease Option, SMMI paid an annual $5,000 net returns royalty to OGT through the maturity of the agreement, and no further payment remains due.

Under the OGT operating agreement, SMMI and ISGC II have 75% and 25% ownership, respectively, in OGT. SMMI is the sole manager and pays all expenses for exploration and development of the property.  The Company has established 75% ownership and full management of the property. OGT's financial information is included 100% in the Company's condensed consolidated financial statements as of March 31, 2026 and December 31, 2025, and for the periods ended March 31, 2026 and 2025.

MFD Investment Holdings

On January 27, 2025, the Company announced a strategic partnership with Swiss-based MFD Investment Holdings SA ("MFD").  The letter agreement signed outlines that MFD will provide additional funding, contributing $1,000,000 in project-related expenditures as well as providing technical support for project development. This partnership adds additional financial strength in advancing South Mountain's technical and economic studies.  The letter agreement is in the form of an option, whereby THMG grants an option to MFD to earn an interest in its South Mountain Project pursuant to which MFD shall have the right, but not the obligation, to complete certain requirements in return for the acquisition of a 10% interest in the Project. 

10


As of March 31, 2026, THMG has recorded $203,498 from MFD related to project expenditures, recognized as a reduction to exploration expenses. No cash was received during the three months ended March 31, 2026; however, the Company recorded a $13,780 receivable for reimbursable project expenditures incurred during the period.

The Company's common stock has a par value of $0.001 with 200,000,000 shares authorized. The Company also has 5,000,000 authorized shares of preferred stock with a par value of $0.0001. The Company also has 22,400,000 warrants outstanding as of March 31, 2026, with a weighted average exercise price of $0.18 and a weighted average life of 1.48 years. No warrants were issued, exercised, or expired during the three months ended March 31, 2026, and there were no changes to the number of warrants outstanding during the period.

 

8. Stock Options

The Company has a Stock Incentive Plan (the "SIP"), that authorizes the granting of stock options up to 10 percent of the total number of issued and outstanding shares of common stock, that provides for the grant of stock options, incentive stock options, stock appreciation rights, restricted stock awards, and incentive awards to eligible individuals including directors, executive officers and advisors that have furnished bona fide services to the Company not related to the sale of securities in a capital-raising transaction. On December 10, 2024, the Company's shareholders, at their Annual Meeting, ratified and reapproved the Stock Option Plan.

On January 29, 2026, the Company granted 200,000 stock options to one employee and a consultant. The options are exercisable at $0.77 per share and expire on January 28, 2031. The options were fully vested upon grant. The fair value of the options was determined to be $136,320 using the Black-Scholes valuation model. As the options were fully vested at issuance, the entire fair value was recognized as share-based compensation expense during the three months ended March 31, 2026. This expense was included in management and administrative expenses on the Company's Condensed Consolidated Statement of Operations. The Company recognized $102,240 in compensation expense for share-based payment awards issued to non-employees as part of the total compensation expense recognized during the same period. 

The fair value of each option award was estimated on the date of the grant using the assumptions noted in the following table:

  January 29, 2026
Stock price $0.74
Exercise price $0.77
Expected volatility 156.11%
Expected dividends -
Expected terms (in years) 5.0
Risk-free rate 3.80%

During the three months ended March 31, 2026, the Company received proceeds of $40,000 from the exercise of 250,000 stock options, including 100,000 options at an exercise price of $0.10 per share and 150,000 options at an exercise price of $0.20 per share.

The following is a summary of the Company's options issued and outstanding under the SIP:

Plan of Operations

The Company, including its subsidiaries, owns mining rights, mining claims, and properties in the mining areas of Nevada and Idaho, which includes its South Mountain Property in Idaho, and its Trout Creek Property in Nevada. 

The Company owns 100% of the outstanding stock of Thunder Mountain Resources, Inc., a Nevada Corporation. Thunder Mountain Resources, Inc. owns 100% of the outstanding stock of South Mountain Mines, Inc. (SMMI), an Idaho Corporation. Thunder Mountain Resources, Inc. completed the direct purchase of 100% ownership of South Mountain Mines, Inc. on September 27, 2007, which at the time, consisted of 17 patented mining claims (approximately 327 acres) located in Owyhee County in southwestern Idaho. After the purchase, Thunder Mountain Resources staked an additional 34 unpatented lode claims covering approximately 550 acres and leased approximately 489 acres of private minerals and land. The Company subsequently acquired additional surface and mineral rights, including a 360-acre millsite property, and has continued to expand its land position through additional claim staking, lease agreements, and acquisitions of private mineral lands.

The Company's plan of operation for the next twelve months, subject to available capital and market conditions, will be to continue to advance the South Mountain Project, including continued baseline environmental and engineering work necessary to complete a Preliminary Economic Analysis (PEA). The Company plans to continue to pursue and evaluate options to advance the South Mountain Project and acquire additional properties through partnerships, joint ventures, option agreements, and strategic relationships.

Financial Condition

Results of Operations:

For the three months ended March 31, 2026, the Company incurred a net loss of $590,758, compared to a net loss of $540,300 for the comparable period in 2025. The increase in net loss was primarily attributable to higher exploration expenditures and increased professional fees, partially offset by lower stock-based compensation expense during the current period.

Three-month period comparisons

Operating expenses for the three months ended March 31, 2026 totaled $594,595, an increase of $53,249, or 10%, compared to $541,346 for the prior year period. This increase was primarily attributable to expanded exploration activities and higher legal and accounting expenses, partially offset by lower stock-based compensation expense during the current period.

Exploration expenditures totaled $167,128 for the three months ended March 31, 2026, compared to $67,073 for the same period in 2025, representing an increase of $100,055, or 149%. The increase was driven by expanded exploration efforts related to the advancement of the Company's mineral interests.

Legal and accounting expenses totaled $95,186 for the three months ended March 31, 2026, compared to $45,810 for the same period in 2025, representing an increase of $49,376, or 108%. The increase primarily reflects higher professional service fees associated with financial reporting, regulatory compliance, and ongoing corporate activities.

Management and administrative expenses totaled $332,281 for the three months ended March 31, 2026, compared to $428,463 for the same period in 2025, representing a decrease of $96,182, or 22%. The decrease was primarily attributable to lower stock-based compensation expense recognized during the current period.

Liquidity and Capital Resources

The Company is in the exploration stage and has not generated revenues from operations. Accordingly, the Company is dependent upon external financing to fund its operations and advance its exploration activities.

As of March 31, 2026, the Company had cash and cash equivalents of $1,813,057 compared to cash and cash equivalents of $2,592,167 as of December 31, 2025. As of May 05, 2026, the Company had cash and cash equivalents of $1,677,457. Management believes the Company's existing cash resources are sufficient to fund its planned operations for at least the next twelve months.

The Company's future liquidity and capital requirements will depend on many factors, including the timing and cost of its exploration activities, evaluation of strategic alternatives and related decisions, and regulatory requirements. The Company's short-term liquidity needs consist primarily of exploration expenditures, lease payments, salaries, administrative expenses, and required principal and interest payments under the seller-financed promissory note issued in December 2025. Longer-term liquidity requirements include potential construction and equipment costs if the Company is able to advance its mining project toward production.

If the Company does not have sufficient cash to complete its exploration programs, it intends to seek additional funding through equity or debt financings or adjust its business plans accordingly. The Company may also consider alternative sources of funding, including potential mergers, asset sales, or additional agreements related to its exploration properties.

During the three months ended March 31, 2026, the Company used net cash in operating activities of $607,786, compared to net cash used in operating activities of $247,613 for the same period in 2025. The increase in cash used in operating activities during the current period was primarily attributable to higher operating expenditures associated with expanded exploration activities and increased professional fees.

15


During the three months ended March 31, 2026, net cash used in investing activities was $211,324, compared to no investing activity during the same period in 2025. Investing activity in the current period consisted of expenditures related to the acquisition of mineral properties.

During the three months ended March 31, 2026, net cash provided by financing activities was $40,000, compared to $130,000 for the same period in 2025. Financing activities during the current period consisted of proceeds from the exercise of stock options, while the prior period included proceeds from the issuance of common stock and warrants.

The Company experienced a net decrease in cash and cash equivalents of $779,110 for the three months ended March 31, 2026, compared to a net decrease of $117,613 for the same period in 2025.

Going Concern

The condensed consolidated financial statements included in this Form 10-Q have been prepared on a going concern basis, which contemplates the realization of assets and the settlement of liabilities in the normal course of business.

The Company is in the exploration stage and has not generated revenues from operations. As of the date of this report, management believes the Company has sufficient cash to meet its normal operating requirements for at least the next twelve months. However, the Company's ability to continue to advance its exploration activities is dependent on its ability to obtain additional financing.

The Company plans, as funding allows, to continue advancing its South Mountain Project and to conduct exploration activities on its mineral properties. The extent and timing of these activities will depend on the availability of capital.

There can be no assurance that additional financing will be available on acceptable terms, or at all. If additional financing is not obtained, the Company may be required to reduce or delay its exploration activities and other expenditures in order to conserve cash and maintain its mineral property interests.

Contractual Obligations

The Company holds several leases pertaining to land parcels adjacent to its South Mountain patented and unpatented mining claims. The details of these leases are as follows:

Lowry Lease:

On October 24, 2008, the Company executed a lease agreement with William and Nita Lowry for a duration of 6 years, encompassing 376 acres at a rate of $20 per acre. The lease incorporated an option to extend for an additional 10 years at a revised rate of $30 per acre. Following the passing of the original lessors, the lease was inherited by Michael Lowry, their son. Commencing October 24, 2025, the Company executed an extension to the lease agreement with Michael Lowry for an additional 21 years, through October 24, 2046. Under the amended lease agreement, the annual rental payments for the first seven years increased to $40 per acre.  The rental rate increases to $50 per acre for the second seven-year period and to $60 per acre for the final seven-year period.

Looten Lease:

On June 2, 2025, the Company executed a lease agreement with Kevin and Jo Looten for an initial term of 7 years, encompassing 18 acres at a rate of $30 per acre. The lease incorporates an option to extend for an additional 10 years at a revised rate of $40 per acre.

Lequerica & Sons Lease:

On August 22, 2025, the Company executed a lease agreement with Lequerica & Sons, Inc. for an initial term of 7 years, encompassing 432 acres at a rate of $30 per acre.

The lease agreement also contains a right of first refusal in favor of the Company with respect to the underlying property, exercisable upon a proposed sale by the lessor.

16


OGT, LLC:

SMMI is the sole manager of the South Mountain Project in its entirety through a separate Mining Lease with Option to Purchase ("Lease Option") with the Company's majority-owned subsidiary OGT.  SMMI has an option to purchase the South Mountain mineral interest for a capped $5 million less net returns royalties paid through the date of exercise. The Lease Option expires in November 2026. Under the Lease Option, SMMI paid annual $5,000 net returns royalty payments to OGT through November 2025. The final $5,000 payment was made in November 2025, and no further payments are required under this arrangement.

Idaho State Mineral Lease:

In March 2026, the Company was awarded mineral lease rights on approximately 3,500 acres of Idaho state land through a competitive auction process and submitted a winning bid of $210,000. In connection with the proposed lease, the Company also paid 2026 lease rent of $10,495 and a minimum annual royalty of $10,000.

As of March 31, 2026, the lease was subject to final approval by the Idaho State Land Board and had not yet been formally executed. Upon execution, the lease is expected to have a 20-year term and require ongoing annual lease payments and minimum royalty obligations to maintain the lease in good standing.

The leases and net royalty payments are summarized in the following table:

Factors that could cause our actual results to differ materially from those in this Quarterly Report on Form 10-Q include the risk factors described in the Company's 2025 Annual Report on Form 10-K. Any of these risk factors could result in a significant or material adverse effect on the Company's business, financial condition and/or results of operations. Additional risks and uncertainties currently unknown to us, or that we currently deem to be immaterial, also may materially adversely affect our business, financial condition, or future results. As of the date of this Quarterly Report on Form 10-Q, there have been no material changes to the risk factors disclosed in the Company's 2025 Annual Report on Form 10-K, other than as set forth below.

Mineral resources are subject to further exploration and development, are subject to additional risks, and no assurance can be given that they will eventually convert to future reserves. Inferred Resources have a great amount of uncertainty as to their existence and their economic and legal feasibility. Mineral interests are periodically assessed for impairment of value and any subsequent losses are charged to operations at the time of impairment. Thunder Mountain Gold evaluated these impairment considerations and determined that no such impairments occurred as of March 31, 2026.

Risks Related to Our Company

We have a history of losses and expect to continue to incur losses in the future.

We have incurred losses since inception and expect to continue to incur losses in the future. We had an accumulated deficit of approximately $11,220,236 as of March 31, 2026. We expect to continue to incur losses unless and until such time as one of our properties enters into commercial production and generates sufficient revenues to fund continuing operations. We recognize that if we are unable to generate significant revenues from mining operations and dispositions of our properties, we will not be able to earn profits or continue operations. At this early stage of our operation, we also expect to face the risks, uncertainties, expenses, and difficulties frequently encountered by companies at the start-up stage of their business development. We cannot be sure that we will be successful in addressing these risks and uncertainties and our failure to do so could have a materially adverse effect on our financial condition.

Item 4.  Mine Safety Disclosures

Pursuant to Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the "Dodd-Frank Act"), issuers that are operators, or that have a subsidiary that is an operator, of a coal or other mine in the United States are required to disclose in their periodic reports filed with the SEC information regarding specified health and safety violations, orders and citations, related assessments and legal actions, and mining-related fatalities.

The information concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Act and Item 104 of Regulation S-K is included in exhibit 95 to this Quarterly Report.

During the three months ended March 31, 2026, the Company did not have any operating mines and therefore had no such specified health and safety violations, orders or citations, related assessments or legal actions, mining-related fatalities, or similar events in relation to the Company's U.S. operations requiring disclosure pursuant to Section 1503(a) of the Dodd-Frank Act.

FAQ

How much did Thunder Mountain Gold (THMG) lose in Q1 2026?

Thunder Mountain Gold recorded a Q1 2026 net loss of $590,758, compared with $540,300 in Q1 2025. The increase mainly reflects higher exploration spending and legal and accounting costs, partially offset by lower stock-based compensation expense during the current period.

What was Thunder Mountain Gold’s cash position as of March 31, 2026?

As of March 31, 2026, Thunder Mountain Gold held $1,813,057 in cash and cash equivalents. Management believes this cash is sufficient to fund planned operations for at least the next twelve months, although further exploration progress will still depend on access to additional financing.

How did exploration expenses change for THMG in Q1 2026?

Exploration expenses rose to $167,128 in Q1 2026 from $67,073 in Q1 2025. Management attributes this 149% increase to expanded exploration efforts aimed at advancing the company’s mineral interests, including work tied to the South Mountain Project in Idaho.

What new mineral lease did Thunder Mountain Gold secure in Idaho?

In March 2026, the company won mineral lease rights on about 3,500 acres of Idaho state land with a $210,000 winning bid. It also paid $10,495 for 2026 lease rent and a $10,000 minimum annual royalty, subject to final state approval.

What are the key terms of THMG’s partnership with MFD Investment Holdings?

Under a letter agreement, MFD Investment Holdings may contribute $1,000,000 in South Mountain project expenditures and technical support. In return, MFD holds an option to earn a 10% interest in the project by meeting specified funding requirements outlined in the agreement.

Does Thunder Mountain Gold face going concern issues in Q1 2026?

The financial statements are prepared on a going concern basis. Management states the company has enough cash for at least twelve months of normal operations but notes that continued advancement of exploration activities will require obtaining additional financing on acceptable terms.
