St George Mining's Araxá Resource Upgrade Sets the Stage for Feasibility Work
Published on 08/17/2026 at 17:12 | Redaktion boerse-global.de
Investors in St George Mining received fresh encouragement on Monday as the company's shares climbed 7.1% to €0.0570, extending a recent run that has lifted the stock roughly 25% above its 52-week low. The move builds on momentum generated by a substantially expanded mineral resource estimate at the company's flagship Araxá project in Brazil, unveiled the previous Tuesday.
The updated figures represent a pivotal step in de-risking the asset. Measured and Indicated resources jumped 155% to 75 million tonnes, grading 0.58% niobium pentoxide (Nb?O?) — equivalent to roughly 435,000 tonnes of contained Nb?O?. That same high-confidence category also hosts approximately 3.98 million tonnes of total rare earth oxides (TREO), including around 760,000 tonnes of neodymium-praseodymium oxide, the magnet metals most coveted by the clean-energy supply chain.
Across the entire mineral resource estimate for Araxá, tonnage rose 57% to 111.2 million tonnes at average grades of 3.57% TREO and 0.57% Nb?O?. The adjacent East Araxá area remains excluded from this calculation, leaving scope for further expansion.
The resource news had already triggered a roughly 6% share-price pop on the day of its release. Monday's advance leaves the stock trading 1.8% above its 50-day moving average — a modest but telling signal of renewed buying interest after a period of weakness.
Engineering Expertise Brought In
With the resource base now better defined, management has pivoted to the next phase of development. The company has engaged Worley as technical advisor to drive economic studies, including feasibility work and detailed mine planning. Worley's remit covers optimising metallurgical processes and infrastructure requirements — essential groundwork before any final investment decision can be contemplated.

Exploration continues apace in parallel. Five diamond drill rigs are operating around the clock, targeting a maiden resource estimate for East Araxá by the fourth quarter of 2026. Success there could enlarge an already substantial resource footprint and reinforce the project's strategic relevance for niobium and rare earth supply.
The resource upgrade was preceded by encouraging metallurgical test results roughly two weeks earlier, which had already lent support to the share price. Together, these developments paint a picture of steady technical progress at a project located in Minas Gerais, a jurisdiction well known for significant critical-metal deposits.
A Strengthened Shareholder Base
The operational advances are being matched by changes at the ownership level. Hancock Prospecting has emerged as the company's largest shareholder with a 10.3% stake — a vote of confidence that markets often interpret as validation of both asset quality and management credibility.
The company's financial position has also been reinforced. Following a two-stage capital raising that brought in A$60 million, St George Mining holds cash of roughly A$98 million. That war chest is intended to fund both the feasibility studies and continued drilling at East Araxá without the pressure of immediate financing needs — a meaningful buffer given the stock's elevated volatility, which stood at 79% on an annualised basis.
Sector Tailwinds
The broader environment for critical minerals remains supportive. Western governments and multilateral organisations have intensified efforts to reduce dependence on single-country suppliers for strategic commodities such as niobium and rare earths. Just last week, a peer company received a conditional US$400 million loan commitment from the US Department of Defense for an Australian project — a reminder that institutional backing for the sector is growing.
Such developments tend to bolster valuations for explorers holding significant deposits in politically stable regions, a category into which St George Mining increasingly fits.
The company also provided transparency on its cash position in its quarterly report, covering the period to 30 June 2026. Following the recent capital measures and transactions, total issued ordinary shares stand at approximately 4.64 billion. Earlier in July, shareholders approved the issuance of shares to Amperex Technology Limited (ATL), a subsidiary of battery giant CATL, and the company secured a 10% interest in Lithium Star through the issue of 12.5 million shares to ATL — further cementing its ties to the technology-metals supply chain.
