Tiernan Continues to Advance Volcan Pre-Feasibility Study and Initiates Environmental Baseline Program

Tiernan Gold advances Volcan project with US$36.2M cash and key technical milestones in Chile.

What the company is saying

Tiernan Gold Corp. details progress at the Volcan Gold Project in Chile, emphasizing technical advances in geological understanding and metallurgical testing. The company highlights a 2026 re-logging program covering 15,077 metres of core, confirming gold mineralization is controlled by silica veining, alteration, and structural features. A 4,486-sample BLEG campaign is underway to inform a domain-aware recovery model for the upcoming Pre-Feasibility Study, with publication targeted for the first half of 2027. Management stresses that permits for environmental baseline work are secured, water rights are owned and exceed project needs, and cash reserves stand at US$36.2 million as of June 30, 2026. The update also introduces recent executive appointments: James Connolly as Executive Vice President of Projects (May 2026), Mario Marchese as Country Manager, Chile (June 1, 2026), and Pascal Lambert-Paradis as CFO (August 1, 2026). The company frames its narrative as disciplined, with capital focused solely on Volcan and no acquisitions or standalone exploration budget.

What the data suggests

The company has completed a 15,077-metre core re-logging program and is extending this work deposit-wide, with ~30% of core already validated as of October 2026. The BLEG campaign covers 4,486 samples across 8,972 metres, with approximately 4,500 core intervals targeted for geometallurgical domaining. Initial metallurgical results from HPGR-crushed material show cyanide-soluble gold recovery ranging from 42.3% to 92.8% in Phase I, indicating significant variability but supporting the HPGR approach. Water rights are robust: two wells authorized for 3.9 million cubic metres per year each (7.8 million total), with a permitted maximum of 170 litres per second, exceeding the project's average requirement of 105 litres per second. Cash reserves are US$36.2 million as of June 30, 2026, with no indication of additional capital needs or burn rate. The Pre-Feasibility Study and updated Mineral Resource Estimate are targeted for H1 2027, with the Environmental Impact Assessment submission planned for H2 2027. All technical and permitting milestones are clearly staged, but no resource or economic figures are disclosed at this time.

Analysis

The announcement provides a detailed and measured update on Tiernan Gold Corp.'s Volcan Gold Project, with a focus on technical progress, permitting, and environmental baseline work. Most claims are factual and supported by specific numerical disclosures (e.g., metres of core re-logged, BLEG samples, water rights, cash balance). Forward-looking statements (such as the targeted PFS and EIA submission dates in 2027) are clearly identified as future milestones, not presented as completed achievements. The tone is positive but not exaggerated, and there is no evidence of narrative inflation or overstatement of realised progress. The company is not claiming imminent production or near-term cash flow, and capital is being deployed in a disciplined, single-project manner. The absence of revenue or profit data is not a deficiency for an exploration-stage company. Overall, the gap between narrative and evidence is minimal, with the language proportionate to the stage of development.

Risk flags

• ●The timeline to value realization is long, with the Pre-Feasibility Study and updated Mineral Resource Estimate not expected until H1 2027 and EIA submission in H2 2027. This exposes the project to permitting, technical, and market risks over an extended period.
• ●No current Mineral Resource Estimate or economic assessment is disclosed, so the project's scale, grade, and economic viability remain unquantified. Investors lack visibility on whether the project will ultimately support a viable mine.
• ●While the company holds substantial water rights, actual permitting depends on demonstrating aquifer sustainability and non-affectation of third-party rights in the EIA. Regulatory or community challenges could delay or constrain project development.
• ●Cash reserves stand at US$36.2 million as of June 30, 2026, but there is no disclosure of burn rate or expected capital requirements through the PFS and EIA stages. Cost overruns or delays could require additional funding.
• ●Stakeholder engagement and Indigenous consultation are described as advanced, but formal consultation is not complete. Social license and community relations remain a potential source of delay or opposition.

Bottom line

Tiernan Gold is making disciplined technical and permitting progress at the Volcan Gold Project, with US$36.2 million in cash and all current workstreams focused on delivering a robust Pre-Feasibility Study and updated Mineral Resource Estimate in the first half of 2027. The company has de-risked key inputs such as water rights and environmental baseline access, but the absence of a current resource estimate or economic study means the project's ultimate value remains speculative. The timeline to any construction or production decision is long, with major milestones still months to over a year away. Investors should watch for the release of the updated Mineral Resource Estimate and PFS as the next substantive catalysts. The most important takeaway is that while technical groundwork is solid and capital is in place for near-term work, the project's economic case is still unproven and subject to execution, permitting, and market risks.

Announcement summary

(TSXV:TNGD) Tiernan Gold Corp. provided a comprehensive update on the Volcan Gold Project, located in the Maricunga Gold Belt, Atacama Region, Chile. In 2026, the company completed a re-logging program covering 15,077 metres of core, confirming that gold mineralization at Volcan is primarily controlled by silica veining, alteration, and structural controls. Tiernan is extending this understanding across the full deposit through additional re-logging and structural interpretation. A Bulk Leach Extractable Gold (BLEG) campaign involving 4,486 samples is underway to build a spatially informed recovery model for the Pre-Feasibility Study (PFS). The company expects to publish an updated Mineral Resources Estimate (MRE) alongside the PFS in the first half of 2027. Initial metallurgical results from SGS Canada Inc. using High Pressure Grinding Rolls (HPGR) on five composites confirmed rapid gold dissolution and improved recovery, with Phase 2 now focused on cyanide consumption, copper management, and process design for carbon-in-column (CIC) and SART. Permits required for environmental baseline mobilization are in hand, with field-work contracts awarded to Chilean environmental contractors and Gestión Ambiental Consultores (GAC) managing the integrated baseline program. The company owns water rights, with two developed wells authorized for extraction of approximately 3.9 million cubic metres per year per well, totaling 7.8 million cubic metres per year and a permitted maximum of 170 litres per second. This exceeds the project's average pumping rate of 105 litres per second as disclosed in the Preliminary Economic Assessment. Field investigations are scheduled for Q4 2026 through Q2 2027 to validate historical assumptions. As of June 30, 2026, Tiernan held cash of US$36.2 million. The PFS is targeted for publication in H1 2027, and the Environmental Impact Assessment (EIA) submission is targeted for H2 2027. Three monitoring stations have been installed at site, with the spring campaign ready to initiate in October 2026. Ausenco Chile Ltda. continues as lead PFS consultant, with Deswik engaged for trade-off studies and mine design. The executive team includes Fausto Di Trapani (President and CEO), James Connolly (Executive Vice President of Projects, appointed May 2026), Mario Marchese (Country Manager, Chile, effective June 1, 2026), and Pascal Lambert-Paradis (Chief Financial Officer, effective August 1, 2026). The company is not pursuing acquisitions and has no standalone exploration budget, focusing capital solely on the Volcan project. Stakeholder mapping and Indigenous consultation planning are advanced, with early community engagement commenced in September 2026. The company’s Chilean subsidiary holds extraction rights authorized by Chile’s Dirección General de Aguas (DGA). The baseline and engagement work are designed to inform project design and reduce permitting risk. The scientific and technical data in the release were prepared and reviewed by M. Antonio Celis C., P.Geo, an independent qualified person under NI 43-101.
