Loyalist Exploration Limited (CSE: PNGC) has released grade-tonnage sensitivity data from the 2026 Mineral Resource Estimate for its 100%-owned Tully Gold Project in Ontario's Timmins Gold Camp. The disclosure, derived from an independent technical report prepared by P&E Mining Consultants Inc. with an effective date of June 15, 2026, is intended to inform the Preliminary Economic Assessment currently underway. Investors may be watching closely, as the sensitivity figures illustrate how recoverable gold responds to varying cut-off grades under underground mining constraints.

Key Points

  • Loyalist Exploration Limited (CSE: PNGC) operates the 100%-owned Tully Gold Project in northeastern Ontario
  • Grade-tonnage sensitivity data from the 2026 MRE has been released to support a Preliminary Economic Assessment now underway
  • At the base-case 1.1 g/t Au cut-off, the project holds an Indicated Resource of 1.62 million tonnes grading 3.16 g/t Au for 164,000 oz gold, and an Inferred Resource of 0.95 million tonnes grading 2.03 g/t Au for 62,000 oz gold
  • Investors should watch for the completion and results of the PEA being prepared by P&E Mining Consultants Inc.

Tully Project Sensitivity Table Highlights Higher-Grade Core at Elevated Cut-Offs

The released sensitivity table covers a range of reporting cut-off grades from 1.0 to 3.0 g/t Au, constrained by a 1.1 g/t Au cut-off and a 1.25-metre minimum mining width. At a 3.0 g/t Au cut-off, the Indicated classification shows 407,000 tonnes grading 9.19 g/t Au containing 120,000 ounces of gold, while Inferred material stands at 150,000 tonnes grading 6.45 g/t Au for 31,000 ounces. The company notes this data is provided for illustrative purposes only and does not constitute a new or updated Mineral Resource Estimate.

Base-Case MRE Underpins Tully's Resource Foundation

The base-case Mineral Resource Estimate, reported without the additional stope-width constraint shown in the sensitivity table, comprises an Indicated Resource of 1.62 million tonnes grading 3.16 g/t Au containing 164,000 ounces of gold. The Inferred Resource stands at 0.95 million tonnes grading 2.03 g/t Au containing 62,000 ounces of gold. The technical report supporting these figures was prepared by P&E Mining Consultants Inc. and carries an effective date of June 15, 2026. The company first announced the MRE on July 7, 2026.

Grade-Tonnage Data to Shape Underground Scenarios in Ongoing PEA

The company states the sensitivity data will factor directly into the Preliminary Economic Assessment currently being prepared by P&E Mining Consultants Inc., which will evaluate potential underground mining scenarios. The PEA is described as examining the impact of different cut-off grades and mining constraints on recoverable material. The company cautioned that the PEA is at an early stage and there is no assurance it will be completed on the currently contemplated timeline or that results will be positive.
