GoldMining Inc. uncovers high-grade gold at São Jorge—Is a major discovery coming?

GoldMining Inc., a publicly traded gold exploration company, has unveiled its most extensive exploration program to date at the São Jorge Project in Pará State, Brazil. The company, listed on the Toronto Stock Exchange under the symbol GOLD and on the NYSE American as GLDG, is investing in an aggressive drilling campaign aimed at expanding known mineral resources and identifying new gold-bearing zones.

Situated in the Tapajós gold district, a historically significant region known for its large-scale artisanal gold rushes, the São Jorge Project has emerged as a key asset within GoldMining Inc.‘s diverse portfolio. The company controls a range of gold and gold-copper projects across the Americas, including Canada, the United States, Colombia, and Peru. The upcoming drilling and surveying activities at São Jorge underscore GoldMining’s confidence in the region’s untapped potential.

What Are the Key Exploration Plans for 2025?

GoldMining Inc. has launched an extensive exploration program that includes up to 5,000 metres of diamond core drilling, targeting both the expansion of the São Jorge deposit and the discovery of new mineralized zones. The company aims to systematically test previously identified geochemical and geophysical anomalies, with a strong emphasis on high-priority targets within the William South and William North prospect areas.

The program also incorporates an expanded geophysical survey, focusing on extending the existing Induced Polarization (IP) survey to the north. This will provide a clearer subsurface picture to refine drill targeting. Additionally, an extensive soil sampling initiative—expected to collect up to 6,000 samples—will further delineate gold mineralization trends across the 46,000-hectare property. Complementary to these efforts, up to 3,000 metres of auger drilling will be conducted over areas with high-tenor soil anomalies, aiding in the identification of near-surface gold occurrences.

What Have Past Exploration Efforts Revealed About São Jorge’s Potential?

GoldMining Inc. has been systematically advancing the São Jorge Project over the past two years. The 2024 exploration program delivered compelling results, particularly at the William South prospect, approximately one kilometre north of the São Jorge deposit. Auger drilling identified several high-grade intercepts, including 1 metre at 17.14 grams per tonne (g/t) of gold, 1 metre at 10.20 g/t, and 5 metres at 2.78 g/t. These results, all from depths shallower than 15 metres, suggest the presence of previously untested gold-bearing structures.

In early 2025, further soil sampling in the William North area returned the highest recorded gold-in-soil anomaly on the property, measuring 5.96 g/t. These findings indicate an extensive mineralized system, reinforcing São Jorge’s potential as a significant gold asset.

Why Is the Tapajós Gold District Important for Gold Exploration?

The Tapajós gold district has a long history of gold production, dating back to the 1980s when the region was a hub for small-scale artisanal mining. Over the decades, industrial-scale exploration has revealed that the district hosts large, structurally controlled gold systems. São Jorge is positioned within a broader mineralized corridor that spans over 12 kilometres by 7 kilometres, characterized by elevated surface geochemical anomalies.

GoldMining’s strategic investment in São Jorge aligns with increasing interest in the Tapajós region, as other companies have also begun recognizing its large-scale potential. The presence of established infrastructure, including highways and power access, further enhances the project’s viability for future development.

What Does the Latest Mineral Resource Estimate Indicate?

GoldMining Inc. recently updated its Mineral Resource Estimate (MRE) for São Jorge, with an effective date of January 28, 2025. The deposit now contains an Indicated resource of 19.42 million tonnes averaging 1.00 g/t gold, translating to approximately 624,000 ounces of gold. The Inferred resource is estimated at 5.56 million tonnes grading 0.72 g/t gold, equating to around 129,000 ounces.

These resource estimates highlight São Jorge’s status as a promising gold asset within GoldMining Inc.’s portfolio. The company has also expanded its land holdings in the region, acquiring an additional 488.45 hectares east of the main deposit, further increasing its exploration footprint.

What Are the Broader Implications for Investors?

GoldMining Inc.’s intensified exploration efforts at São Jorge signal a strong commitment to unlocking shareholder value. With gold prices experiencing sustained interest amid global economic uncertainty, companies with significant resource growth potential, like GoldMining, have garnered increased attention from investors.

As of March 17, 2025, GoldMining Inc.’s stock was trading at approximately $0.88 USD. The success of the São Jorge exploration program could act as a catalyst for future stock performance, particularly if the company continues to delineate additional high-grade mineralization.

GoldMining’s disciplined acquisition strategy and focus on resource expansion position it as a key player in the Americas’ gold exploration sector. If São Jorge delivers on its exploration potential, it could significantly enhance the company’s overall valuation and development prospects.

What’s Next for GoldMining Inc. and the São Jorge Project?

As the 2025 exploration program progresses, investors and industry stakeholders will be closely monitoring GoldMining Inc.’s drilling results. The company’s systematic approach, which combines historical data with modern geophysical and geochemical techniques, provides a strong foundation for further discoveries.

With large-scale gold systems historically proven in the Tapajós district, São Jorge remains a critical project in GoldMining’s portfolio. The coming months will be pivotal in determining whether the project can advance from an exploration-stage asset to a more defined development opportunity.
