ip technical

"ongoing IP survey covering 49 line-kilometres to the east of the Deposit"

Intellectual property (IP) is the set of legal rights that protect a company’s ideas, inventions, brand names and secret methods—think of it as the recipes, blueprints and logos a business owns. For investors, IP matters because these rights can create exclusive advantages, produce licensing income, and increase a company’s value by preventing competitors from copying key products or brands. Strong, enforceable IP often signals a more defensible and potentially profitable business.

g/t technical

"12 m ("m") at 2.38 grams per tonne ("g/t") gold ("Au") from 13 m depth"

g/t stands for grams per tonne, a measure of how many grams of a metal—most often gold or other precious metals—are contained in one metric tonne of rock or ore. Investors use it to judge how “rich” a mineral deposit is: higher g/t means more metal per amount of material to process, which can make mining cheaper and projects more likely to be profitable—like measuring teaspoons of sugar per cake to gauge sweetness value.

au technical

"12 m ("m") at 2.38 grams per tonne ("g/t") gold ("Au") from 13 m depth"

Au is the chemical symbol and common shorthand for gold, the precious metal used as a store of value, industrial input, and backing for some investments. Investors watch Au because changes in its price often signal shifts in inflation expectations, currency strength, or economic uncertainty—think of it as a financial safe-haven like an emergency fund that many turn to when other assets look risky.

ni 43-101 regulatory

"a qualified person as defined in National Instrument 43-101 – Standards of Disclosure"

A Canadian regulatory standard that sets the rules for how mining and exploration companies must report mineral resources and reserves, requiring technical reports prepared or signed off by an independent, certified expert. It matters to investors because it creates a consistent, transparent “inspection report” for mining projects, making it easier to compare prospects, judge the reliability of claims, and assess geological and financial risk before investing.

qualified person regulatory

"Mr. Smith is also a qualified person as defined in National Instrument 43-101"

A qualified person is someone with specialized knowledge, experience, and training in a particular field, allowing them to accurately assess and verify information or work. Their expertise helps ensure that reports, evaluations, or decisions are trustworthy and meet required standards. For investors, a qualified person provides confidence that the information they rely on is credible and properly validated.

VANCOUVER, BC, March 30, 2026 /PRNewswire/ - GoldMining Inc. (TSX: GOLD) (NYSE American: GLDG) (the "Company" or "GoldMining") is pleased to announce that it has commenced an exploration-focused drill program on the Company's 100%-owned São Jorge Project ("São Jorge" or the "Project") in the Tapajós gold district, Pará State, Brazil.

Highlights:

• Systematic drilling to follow up on high-priority targets generated through 2025 exploration in close proximity to the existing São Jorge mineral resource (the "Deposit")
• Two-rig, 8,000-metre drilling program currently underway, fully funded 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 2 km of the Deposit with initial drill results (as reported on January 6, 2026) highlighted by:
  • 12 m ("m") at 2.38 grams per tonne ("g/t") gold ("Au") from 13 m depth, including 1 m at 22 g/t Au (SJRC-048-25)
  • 4 m at 1.11 g/t Au from 46 m depth (SJRC-049-25)
  • 1 m at 1.23 g/t Au from 16 m depth (SJRC-047-25)
  • Large untested Induced Polarity ("IP") chargeability anomaly
• Significant expansion of existing geophysical coverage with an ongoing IP survey covering 49 line-kilometres to the east of the Deposit
• Emerging and expanding mineral system defined by a 12 km by 7 km 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 São Jorge. We are exploring in the prolific Tapajós 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."

What geophysical work is GoldMining conducting at São Jorge in 2026?

An induced polarity survey is expanding coverage with a 49 line‑kilometre program east of the Deposit. According to the company, the IP survey aims to test large chargeability anomalies identified in prior work.

How large is the exploration footprint at São Jorge referenced by GLDG?

The company describes an emerging mineral system spanning about 12 km by 7 km of elevated surface geochemical anomalies across its 46,485‑hectare property. According to the company, this highlights broader exploration potential.

Will the 2026 drilling at São Jorge immediately change GLDG's mineral resource estimate?

No immediate update has been announced; the 2026 drilling is exploration‑focused and aimed at testing targets. According to the company, the program is intended to generate data that could support future resource work if warranted.

What infrastructure supports GoldMining's 2026 São Jorge program (GLDG)?

São Jorge benefits from existing grid power, highway access, and a fully operational 50‑person camp, allowing more program spending to focus on drilling. According to the company, this infrastructure improves operational efficiency onsite.
