Company Description
Calibre Mining Corp. (OTCQX: CXBMF; TSX: CXB) historically operated as a Canadian-listed, Americas focused, mid-tier gold producer. According to the company’s public disclosures, Calibre described itself as a growing gold producer with a pipeline of development and exploration opportunities across Newfoundland & Labrador in Canada, Nevada and Washington in the United States, and Nicaragua. The company emphasized responsible operations and a disciplined approach to growth, highlighting a strong balance sheet, operating cash flow, accretive development projects and district-scale exploration opportunities as key elements of its strategy.
Calibre’s business combination with Equinox Gold Corp. marks a major change in its corporate status. On June 17, 2025, Equinox Gold announced the successful completion of a court-approved plan of arrangement under which Equinox Gold acquired all of the issued and outstanding common shares of Calibre Mining. Following this transaction, Equinox Gold stated that it intends to cause Calibre to delist its shares from the Toronto Stock Exchange and apply to cease to be a reporting issuer and terminate its public company reporting requirements as soon as possible. As a result, CXBMF now represents a former standalone issuer that has been integrated into Equinox Gold.
Before the completion of the arrangement, Calibre’s disclosures described an asset base that included the Valentine Gold Mine in Newfoundland & Labrador, Canada, as well as operations in Nevada and Washington in the USA and in Nicaragua. The company characterized Valentine as a long-life, low-cost cornerstone asset in Canada and noted a strong pipeline of development and exploration opportunities across its portfolio. Calibre also highlighted its focus on sustainable value for shareholders, local communities and other stakeholders through responsible operations.
The combination of Equinox Gold and Calibre has created what the companies describe as an Americas-focused diversified gold producer anchored by two Canadian gold mines: the Greenstone Gold Mine in Ontario and the Valentine Gold Mine in Newfoundland & Labrador. Public statements from both companies indicate that, with 100% ownership of Greenstone and Valentine, the combined entity is positioned as the second largest gold producer in Canada, with a portfolio of operating mines in five countries in the Americas and a pipeline of development and expansion projects.
For investors researching CXBMF today, it is important to understand that Calibre Mining is no longer an independent public company. The June 17, 2025 news release from Equinox Gold and Calibre confirms completion of the business combination and explains that Calibre shareholders receive Equinox Gold shares under the terms of the plan of arrangement. Equinox Gold has stated that Calibre shares held in online or brokerage accounts will update automatically to reflect receipt of Equinox Gold shares, while registered Calibre shareholders must follow the instructions in the Letter of Transmittal to receive their Equinox Gold shares.
Historically, Calibre’s corporate communications emphasized several themes: growth in gold production across its Americas-focused portfolio, reinvestment in exploration, and development of new satellite deposits. The company also highlighted district-scale exploration programs, including a large exploration drill program at the Valentine Gold Mine property, and noted that its growth capital investments included underground and open pit mine development, waste stripping and strategic land acquisitions. These elements formed the basis of Calibre’s growth-oriented gold producer profile prior to its combination with Equinox Gold.
Following the completion of the arrangement, investors seeking ongoing exposure to the assets and operations formerly associated with Calibre Mining should review Equinox Gold Corp. (TSX: EQX; NYSE American: EQX). Equinox Gold’s public disclosures describe a Canadian mining company with gold operations in Canada, the United States and Brazil, and a pipeline of development and expansion projects across the Americas. The combined company’s communications emphasize a focus on disciplined execution, operational performance and long-term value creation, with the Calibre assets and team integrated into this broader platform.
Business transformation and historical context
Calibre’s transition from a standalone mid-tier gold producer to part of Equinox Gold is documented across a series of public announcements. On February 23, 2025, Equinox Gold and Calibre announced that they had entered into a definitive arrangement agreement for an at-market business combination, with Equinox Gold acquiring all issued and outstanding Calibre shares pursuant to a court-approved plan of arrangement. Subsequent Calibre news releases reported securityholder approval of the transaction, receipt of court approval, and ultimately the closing of the business combination in June 2025.
These disclosures explain that the strategic rationale for the transaction included creating a major diversified gold producer in the Americas, combining operating mines and development projects in multiple countries, and anchoring the portfolio with the Greenstone and Valentine gold mines in Canada. The companies also cited increased production, diversification, scale, and a pipeline of development and expansion projects as expected benefits of the combined entity.
Implications for CXBMF shareholders
For holders of CXBMF (the OTCQX listing of Calibre Mining), the arrangement means that their economic exposure has shifted from a standalone mid-tier gold producer to a share position in Equinox Gold, subject to the exchange ratio described in the arrangement documentation. Public communications from Calibre and Equinox Gold explain that Calibre shareholders receive Equinox Gold common shares based on an agreed share exchange ratio, and that Calibre intends to delist and cease to be a reporting issuer following completion of the transaction.
As a result, CXBMF should be viewed primarily as a historical ticker representing Calibre Mining prior to its acquisition by Equinox Gold. Research into Calibre’s historical operations, exploration programs and development projects remains relevant for understanding the origins and composition of Equinox Gold’s current asset base, particularly in relation to the Valentine Gold Mine and Calibre’s operations in Nicaragua and the United States.
Position within the mining sector
Within the broader mining, quarrying and oil and gas extraction sector, Calibre Mining was focused specifically on gold production and exploration in the Americas. Company disclosures consistently described Calibre as a Canadian-listed, Americas focused, growing mid-tier gold producer, distinguishing it from larger global diversified miners and from early-stage exploration-only companies. Its combination with Equinox Gold has contributed to the formation of a larger Americas-focused gold producer with multiple operating mines and development projects.
