GoldMining Inc. Launches 2025 Exploration Program, São Jorge Project, Brazil

Rhea-AI Summary

GoldMining Inc. (TSX: GOLD) (NYSE American: GLDG) has announced its largest exploration program at the São Jorge Project in Brazil's Tapajós gold district. The 2025 program includes:

• Up to 5,000 metres of drilling to expand the São Jorge deposit
• 3,000 metres of auger drilling over high tenor soil anomalies
• 6,000 soil samples to test the broader mineral system
• Extended IP survey over William South and North prospects

The program builds on successful 2024 results, which revealed significant high-grade auger drill intercepts at William South, including 1m at 17.14 g/t Au and 5m at 2.78 g/t Au. Recent 2025 soil sampling at William North yielded the project's highest-ever gold-in-soil anomaly of 5.96 g/t Au. The São Jorge mineral system spans a 12km x 7km footprint, with the deposit remaining open along strike.

VANCOUVER, BC, March 18, 2025 /PRNewswire/ - GoldMining Inc. (the "Company" or "GoldMining") (TSX: GOLD) (NYSE American: GLDG) is pleased to announce plans to commence a major exploration program on the Company's 100% owned São Jorge Project ("São Jorge" or the "Project") in the Tapajós gold district, Pará State, Brazil.

Highlights:

• Planned drilling campaign of up to 5,000 metres
  • Systematic drilling to target expansion of the São Jorge deposit (the "Deposit") along strike
  • Drill testing new zones of potential bedrock mineralization at high priority geochemical and geophysical targets
• Geophysical surveying including expansion of the existing IP survey northwards over the William South and North prospect areas
• Additional auger drilling of up to 3,000 metres over high tenor soil anomalies
• Soil sampling program of up to 6,000 samples to test and expand the broader mineral system across the Project

The Company has already commenced field activities including soil sampling, mapping and prospecting, and is planning a follow-up diamond core drilling program for the 2025 field season. In the 2024 drill program results, numerous high-grade auger drill intercepts provided compelling targets to systematically explore for new gold discoveries within the São Jorge mineral system (see news release dated February 26, 2025):

• High-grade auger drill intercepts at William South in 2024 included 1 metre ("m") at 17.14 g/t Au, 1 m at 10.20 g/t Au, 1 m at 8.01 g/t Au and 5 m at 2.78 g/t Au, all from shallow depths of less than 15 m below surface
• Recent soil sampling in 2025 has returned the highest ever gold-in-soil anomaly of 5.96 g/t Au at the William North prospect area

The Deposit occurs within an emerging and expanding mineral system defined by a 12 km x 7 km footprint of elevated surface geochemical anomalies surrounding the Deposit, thereby highlighting the broader exploration potential of the Project.

Alastair Still, Chief Executive Officer of GoldMining, commented: "GoldMining is excited to be launching a comprehensive exploration program at our São Jorge Project that will be the largest exploration program in the 14+ year history of our Company, and is a testament to our belief in the previously untapped exploration potential at São Jorge. We have assembled a first-class exploration team led by our President Paulo Pereira, a veteran Brazilian geologist, and our VP Exploration Tim Smith who has over thirty years of global gold experience. It follows that an experienced technical team, combined with São Jorge's demonstrated prospectivity, proximity to existing highway and power infrastructure, regional scale property size exceeding 46,000 hectares and location within an emerging gold producing district, makes for a compelling growth opportunity." 

São Jorge Project Exploration Opportunity and Upside

Over the past two years the Company has embarked on a systematic exploration campaign to compile comprehensive exploration datasets to test the broad extent and continuity of the São Jorge mineral system (see Figure 2). The associated surface sampling program has successfully delineated several new exploration targets comprising gold ± copper ± molybdenum ± silver soil geochemical anomalies which cumulatively outline a large mineral system defined by a 12 km x 7 km geochemical footprint surrounding the Deposit.

Follow up testing has to date produced very encouraging results, including diamond core drilling which stepped out 1 kilometre west of the Deposit to confirm the mineralized corridor remains open along strike (see news release dated September 9, 2024). Additional fences of diamond core drilling are now planned to extend the São Jorge mineralized corridor. 

At William South, located 1 kilometre north of the Deposit, auger drilling intended to test the source of mineralization beneath high tenor soil anomalies has to date returned numerous high-grade intercepts (see news releases dated September 9, 2024, and November 11, 2024) including:

• 1 m at 17.14 g/t Au from 12 m depth;
• 5 m at 2.78 g/t Au from 10 m depth;
• 1 m at 10.2 g/t Au from 14 m depth;
• 1 m at 8.01 g/t Au from 6 m depth;
• 1 m at 3.78 g/t Au from 10 m depth; and
• 3 m at 1.05 g/t Au from 12 m depth.

These auger drilling results indicate the potential to discover new gold mineralized zones at William South, which will be complemented with the assistance of an extended IP survey to help refine diamond core targeting. The Company also plans to undertake additional step-out auger drilling to search for new gold-in-bedrock drill targets, such as at William North where recent gold-in-soil sampling has returned the highest tenor soil sample on the property of 5.96 g/t Au.
