GoldMining Inc. reports exploration and project-development news for a portfolio of resource-stage gold and gold-copper assets in the Americas. Recurring updates cover preliminary economic assessments, NI 43-101 technical information, drilling programs, and technical work at projects such as La Mina in Colombia, São Jorge in Brazil, and the Whistler Gold-Copper Project in Alaska through its majority owned subsidiary U.S. GoldMining.
The company’s news also includes annual and interim reporting, management discussion and analysis, capital-structure disclosures, material agreements, and leadership appointments tied to development of its project portfolio.
GoldMining (GLDG) has begun a pre-feasibility study and infill drilling at its wholly owned São Jorge gold project in Brazil.
Three rigs are active on an initial planned 6,000-metre program. GoldMining aims to improve resource confidence and upgrade inferred resources within the existing preliminary economic assessment's pit shell to higher-confidence categories. It expects drilling results to support an updated mineral resource estimate for the study, which it anticipates completing in the first half of 2028.
Fresh core samples will support metallurgical testing to help determine a processing route, while drilling data will inform open-pit stability analysis. Planning is also underway for geotechnical and groundwater drilling around the proposed pit and drilling beneath proposed infrastructure sites. The study is intended to further evaluate economic viability and refine capital and operating cost estimates.
GoldMining (GLDG) published its fourth annual Sustainability Report, covering its sustainability performance and initiatives for fiscal year 2025.
The company recorded zero employee lost-time incidents, 1,887 hours of health, safety and emergency-response training, and zero reportable environmental incidents. It reported no known material regulatory non-compliance and reclaimed 100% of drill sites in fiscal 2025. Human rights and sustainability screening covered 50 suppliers, and 100% of staff, contractors and temporary workers were hired in-country. The report also analyzed Scope 1 and Scope 2 greenhouse gas emissions against the fiscal 2024 baseline.
GoldMining (GLDG) appointed Alexandre Soares Pimenta as Project Director to lead the next phase of advancement at São Jorge in Brazil. The project is 100%-owned and located in Pará State. Pimenta brings more than 25 years of experience in mining, engineering and industrial project development.
The company is initiating pre-feasibility technical and engineering work to evaluate requirements for a potential future development decision. A proposed infill diamond drilling program using multiple rigs is in its final preparation stages to improve deposit definition.
The previously announced preliminary economic assessment modelled US$532 million in after-tax net present value at a 5% discount rate and a 42.4% after-tax internal rate of return, assuming gold at US$3,500 per ounce. It envisaged average annual production of 51,250 ounces over 10.6 years. These preliminary economics include inferred resources and are not certain to be realized.
GoldMining (GLDG) reported initial drilling results showing 399.9 metres of continuous gold-copper mineralization at its wholly owned Yarumalito project in Colombia.
Hole YAR-45 returned 0.45 grams per tonne gold equivalent (AuEq), a measure combining metal values, from surface to the hole's end. Grades were 0.34 g/t gold, 0.09% copper and 1.21 g/t silver. Higher-grade intervals included 33.2 metres at 0.81 g/t AuEq, 74.7 metres at 0.61 g/t AuEq and 36.0 metres at 0.65 g/t AuEq.
Drilling validated the three-dimensional geological model of the P-1 host unit, with mineralization remaining open along strike and at depth. Four holes totaling 1,218 metres were completed on schedule and within budget; assays for YAR-46 through YAR-48 remain pending. GoldMining expects to integrate the results into updated geological and mineral resource models. The project has direct road access and nearby grid power.
GoldMining (NYSE American: GLDG, TSX: GOLD) filed an NI 43-101 Technical Report containing the preliminary economic assessment for its São Jorge gold project in Pará State, Brazil, effective June 9, 2026. The PEA is preliminary, includes inferred resources and, as stated by the company, there is no certainty results or conceptual economics will be realized.
The PEA models an after-tax NPV5% of $532 million and 42.4% IRR at a $3,500/oz gold price, rising to a modelled after-tax NPV5% of $836.8 million, 58.6% IRR and 2.4-year payback at $4,400/oz. Initial capital is estimated at $202 million (including 25% contingency), implying about a 2.6x NPV5%/capex ratio.
The study contemplates a conventional open-pit, 5,500 tpd operation, average annual production of about 51,250 oz over a 10.6-year mine life, peak 57,200 oz in years 2–4, metallurgical recovery of 90% Au, and an estimated life-of-mine AISC of $1,464/oz. GoldMining reports it is working to commence pre-feasibility studies while advancing permitting toward a construction decision.
GoldMining (NYSE American: GLDG) issued a mid‑year 2026 update highlighting balance sheet strength, project studies and exploration progress. The company reports no debt and about US$185 million in cash and publicly traded securities, nearly matching its June 24, 2026 market cap of US$191 million.
Recent PEAs outline conceptual NPV5% values of US$532 million for São Jorge, US$1.0 billion for La Mina, and US$2.0 billion for the Whistler Gold‑Copper Project via 74%-owned U.S. GoldMining. GoldMining also reports a large resource base and active drilling in Brazil, Colombia and Alaska, while advancing optionality at the Yellowknife Gold Project. All PEAs are preliminary, rely in part on inferred resources, and there is no certainty the conceptual economics will be realized.
GoldMining (NYSE American: GLDG) announced a positive PEA for its São Jorge gold project in Brazil, outlining an after-tax NPV5% of $532 million, 42.4% IRR, and 2.8-year payback at $3,500/oz gold with $202 million initial capital.
The study forecasts average annual production of about 51 koz over a 10.6-year mine life, total production of 543 koz, and estimated AISC of $1,464/oz. GoldMining reports a balance sheet with roughly $183 million in cash and securities and plans to advance pre-feasibility and permitting. The PEA is preliminary and includes Inferred resources, so results are uncertain.
GoldMining (NYSE American: GLDG) filed an NI 43-101 PEA technical report for its La Mina gold-copper project in Antioquia, Colombia, effective April 22, 2026.
