GoldMining files technical report for Colombia gold project

GoldMining Inc. (NYSE American: GLDG) filed a technical report for its La Mina Project in Antioquia, Colombia, detailing a preliminary economic assessment with an after-tax net present value of $1.0 billion and internal rate of return of 32.2%.

The report, dated April 22, 2026, outlines a conventional open pit mining operation processing 15,000 tonnes per day. Initial capital expenditures are estimated at $523 million with a payback period of approximately 2.7 years.

The assessment projects average annual production of 152,400 ounces of gold equivalent over the first five years, with total life-of-mine production of 1.5 million ounces of gold equivalent over 11.2 years. This includes 1.2 million ounces of gold, 2.6 million ounces of silver, and 195 million pounds of copper.

At current spot prices of approximately $4,775 per ounce of gold, $5.75 per pound of copper, and $77 per ounce of silver, the after-tax net present value increases to approximately $1.8 billion with an internal rate of return of 49.1%.

The study estimates total cash costs of $872 per ounce of gold and all-in sustaining costs of $1,045 per ounce of gold on a by-product basis. The processing operation would utilize standard froth flotation and leach circuits achieving metallurgical recoveries of 91% for gold, 80% for copper, and 64% for silver.

The company notes the preliminary economic assessment includes inferred mineral resources and there is no certainty the reported results will be realized. The technical report is available on the company's profiles at sedarplus.ca and sec.gov.
