GOLDMINING COMMENCES 2026 EXPLORATION PROGRAM AT ITS SAO JORGE PROJECT, BRAZIL

Goldmining Inc. has commenced an exploration-focused drill program on the company's 100-per-cent-owned Sao Jorge project in the Tapajos gold district in Para state, Brazil.

Highlights:

• Systematic drilling to follow up on high-priority targets generated through 2025 exploration in close proximity to the existing Sao Jorge mineral resource;
• Two-rig, 8,000-metre drilling program currently under way, fully financed and actively turning on site;
• Testing new zones of potential bedrock mineralization at high-priority geochemical and geophysical targets;
• Targets include William South, located within two kilometres of the deposit with initial drill results (as reported on Jan. 6, 2026), highlighted by:
  • 12 metres at 2.38 grams per tonne gold from 13 metres depth, including one metre at 22 g/t Au (SJRC-048-25);
  • Four metres at 1.11 g/t Au from 46 metres depth (SJRC-049-25);
  • One metre at 1.23 g/t Au from 16 metres depth (SJRC-047-25);
  • Large untested induced polarization (IP) chargeability anomaly;
• Significant expansion of existing geophysical coverage with a continuing IP survey covering 49 line kilometres to the east of the deposit;
• Emerging and expanding mineral system defined by a 12-kilometre-by-seven-kilometre footprint of elevated surface geochemical anomalies surrounding the deposit, highlighting the broader exploration potential of the project.

Alastair Still, president and chief executive officer of Goldmining, commented: "This drill program marks a pivotal step in our 2026 exploration strategy at Sao Jorge. We are exploring in the prolific Tapajos gold district, with an estimated 30 million ounces of historical surficial gold production, and our recent targeting work has outlined some of the most robust and continuous gold anomalies we've seen on our 46,485-hectare property. We already have excellent infrastructure in place, including grid power, highway access and a fully operational 50-person camp, so more of our dollars can go directly towards potentially expanding our mineral resource estimate."
