GoldMining’s Brazilian Bet: Strong Economics Meet Development Hurdles

VANCOUVER, BC – July 22, 2026 – In the high-stakes world of mineral exploration, turning geological promise into economic reality is the ultimate goal. GoldMining Inc. has just taken a significant stride in that direction, filing a formal technical report that paints a glittering picture for its São Jorge gold project in Brazil's Pará State. The Preliminary Economic Assessment (PEA) outlines a project with robust financial metrics, a manageable price tag, and a clear operational path. Yet, as with any venture of this scale, the devil is in the details, and the road from a preliminary study to pouring the first gold bar is a long one.

At the heart of the announcement is a set of figures designed to capture investor attention. The PEA models an after-tax net present value (NPV) of $532 million and a stellar internal rate of return (IRR) of 42.4%. These numbers are predicated on a base case gold price of $3,500 per ounce, a bullish but increasingly plausible forecast in today's volatile economic climate. For GoldMining, which has strategically amassed a portfolio of assets across the Americas, this report marks a pivotal moment, advancing a key project from a line item on a map to a tangible development opportunity.

Deconstructing the Dollars: A Look Inside the PEA

The allure of the São Jorge project lies in its potent combination of high potential returns and low initial barriers to entry. An initial capital expenditure of just $202 million—a figure that includes a healthy 25% contingency—is remarkably modest for a project of this scale. This creates an attractive NPV-to-capex ratio of 2.6, suggesting that for every dollar invested in construction, the project is projected to generate $2.60 in value. This capital efficiency is a critical differentiator in an industry where mega-project budget overruns are common.

However, the economics are highly sensitive to the price of gold. While the $3,500 per ounce base case drives the impressive returns, it’s worth noting that the underlying mineral resource was calculated in early 2025 using a more conservative long-term price of $1,950 per ounce. This highlights both the project's leverage and its risk; its profitability soars in a high-price environment but would be significantly compressed at lower spot prices. To illustrate the upside, the company also modeled a scenario at $4,400 per ounce gold, which sends the NPV soaring to $836.8 million and the IRR to an eye-watering 58.6%, with a rapid payback of just 2.4 years.

Profitability isn't just about revenue; it's about cost control. The PEA estimates an All-In Sustaining Cost (AISC) of $1,464 per ounce over the mine's 10.6-year life. At the base case gold price, this leaves a potential margin of over $2,000 per ounce, providing a substantial cushion against operational hiccups or a moderate downturn in gold prices. As CEO Alastair Still commented, the report highlights the asset's "potential resilient margins and rapid payback profile," a combination that is essential for securing financing and shareholder confidence.

Brazil's Golden Opportunity: Infrastructure and Operations

The project's attractive capital cost isn't an accident of accounting; it's a direct result of its strategic location. Situated in the Tapajós Gold District of Pará State, São Jorge benefits from what the company calls an "infrastructure advantage." Unlike many remote mining projects that must spend hundreds of millions on roads and power plants, this one sits adjacent to paved highways and existing power lines. Critically, it can tap into a new 138 kV powerline recently built for G Mining Ventures' nearby Tocantinzinho mine, piggybacking on regional development to lower its own costs.

The operational plan is straightforward and conventional, which further reduces technical risk. It envisions a standard open-pit truck-and-shovel operation processing 5,500 tonnes of ore per day. Using a proven flowsheet of gravity and leach circuits, the project aims for a high metallurgical recovery of 90%. Over its decade-plus lifespan, the mine is expected to produce an average of 51,250 ounces of gold annually, providing a steady stream of cash flow after the initial capital is paid back. This production scale is meaningful and positions São Jorge as a solid, mid-tier asset if it reaches production.

The Path Forward: From Paper to Production

While the PEA provides a compelling blueprint, it is crucial to recognize its limitations. The report is, by its own definition, "preliminary in nature." Its calculations are based on "inferred mineral resources," which are considered too geologically speculative to be classified as proven reserves. There is, as the company's mandatory disclaimer states, "no certainty that the reported results will be realized."

GoldMining Inc. is now moving to address this uncertainty. The next step is to commence a pre-feasibility study (PFS), a more rigorous and detailed engineering analysis designed to upgrade resources, refine costs, and further de-risk the project. This is a critical phase where promising concepts are tested against hard engineering and economic realities.

Simultaneously, the company must navigate Brazil's complex permitting environment. Any mining project in the Amazon region faces intense scrutiny from environmental agencies like IBAMA and requires careful community engagement. While the Tapajós district is an established mining area, securing all necessary licenses is a painstaking, multi-year process that represents a significant non-technical risk. Fortunately, GoldMining appears well-positioned to fund this next phase. With a reported balance sheet of around $183 million in cash and securities as of mid-2026, it has the capital to advance the PFS and permitting activities without immediately needing to tap the market for more funds.

This financial strength gives the company strategic flexibility as it moves São Jorge up the value chain. While the $202 million construction cost is far off, a successful PFS would make the project significantly more attractive for potential debt financing, joint-venture partnerships, or even an acquisition by a larger producer. For now, the focus remains on methodical de-risking, with plans to also drill nearby exploration targets to potentially expand the resource and enhance the project's overall value.
