STLLR Gold's Hollinger Tailings Project Maiden Mineral Resource Estimate Provides A Strong Foundation for Exploring Future Short-Term Development Under Ontario's New Recovery of Minerals Regime
None
On November 25, 2025, STLLR Gold announced the maiden Mineral Resource Estimate (MRE) for its 100%-owned Hollinger Tailings Project in Timmins, Ontario. The MRE outlines: - Indicated Resource: 36.2 million tonnes (Mt) at an average grade of 0.35 grams per tonne (g/t) gold (Au) for 412,000 contained ounces of gold. - Inferred Resource: 7.7 Mt at an average grade of 0.37 g/t Au for 93,000 contained ounces of gold.
The company states this MRE is a significant de-risking milestone that provides a strong foundation for exploring near-term development. They highlight the project's potential for near-term value creation due to uniform mineralization and a favorable, streamlined permitting pathway under Ontario's new "Recovery of Minerals Regime."
The release of a maiden MRE for the Hollinger Tailings Project is a materially positive event for STLLR Gold. This news delivers on a key corporate objective outlined at the beginning of 2025, demonstrating management's ability to execute on its stated plans.
- Alignment with Expectations: The MRE follows a series of positive drilling results from the characterization program released between April and August 2025, which showed consistent, albeit low-grade, mineralization. While the final average grade of 0.35 g/t is at the lower end of the highlighted drill intercepts, this is expected in a global resource calculation and confirms the overall tenor of the deposit.
- Strategic Importance: This MRE is strategically critical. The company's flagship Tower Gold Project, while very large (4.0M oz Indicated, 7.0M oz Inferred), comes with a prohibitively high initial CAPEX of US$1.37 billion as per the May 2025 PEA. The Hollinger project, as a tailings reprocessing opportunity, represents a potential low-capital, near-term path to cash flow. This could provide a source of non-dilutive funding and demonstrate operational capability, which would be crucial in de-risking the financing path for the much larger Tower project.
- De-risking: Quantifying over 400,000 ounces in the Indicated category provides a solid basis for a Preliminary Economic Assessment (PEA). This moves the project from a conceptual target to a defined mineral asset. The mention of a streamlined permitting process under a new provincial regime is a significant positive, as permitting is often a major hurdle and source of delays.
While the resource size is modest and the grade is low, the nature of tailings projects means economics are driven by low-cost processing and high recovery rates rather than high grades. This MRE is the necessary first step to prove that economic viability. The positive market reaction will depend on the forthcoming PEA, but this news successfully advances a key part of the company's strategy.
STLLR Gold Inc. is a Canadian gold development company focused on advancing its portfolio of projects in tier-one jurisdictions.
- Tower Gold Project (Ontario): This is the company's flagship asset. It is a large-scale project with a May 2025 PEA outlining a 4.0M oz Indicated and 7.0M oz Inferred resource. The PEA projects average annual production of 273,000 oz over 19 years, but with a very high initial CAPEX of US$1.37 billion.
- Hollinger Tailings Project (Ontario): A near-surface gold reprocessing opportunity containing tailings from a historic high-grade mine. The focus is on a low-capital, streamlined path to potential near-term production to complement the larger Tower project. The November 2025 maiden MRE defined 412,000 oz Indicated and 93,000 oz Inferred.
- Colomac Gold Project (Northwest Territories): A secondary, large-scale gold project with a 2023 PEA. It is currently a lower priority than the Ontario assets.
All projects are 100% owned, though Hollinger is subject to a 1.5% net smelter royalty.
