Loyalist Exploration Limited (CSE: PNGC) is pleased to announce that the independent Technical Report supporting the 2026 Mineral Resource Estimate for its 100%-owned Tully Gold Project, located in the prolific Timmins Gold Camp of northeastern Ontario, has now been filed on the Company’s SEDAR+ profile.

The Technical Report, which supports the 2026 MRE for the Project, is entitled “NI 43-101 Technical Report and Mineral Resource Estimate, Tully Gold Project, Timmins, Ontario, Canada” and was prepared by Charles Spath, M.Sc., P.Geo., and Eugene Puritch, P.Eng., FEC, CET, of P&E Mining Consultants Inc. each of whom is an independent Qualified Person as defined by NI 43-101. The Technical Report has an effective date of June 15, 2026 and a report date of August 21, 2026, and was prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects and the CIM Definition Standards for Mineral Resources and Mineral Reserves.

On July 7, 2026, Loyalist announced a 2026 Mineral Resource Estimate for the 100%-owned Tully Gold Project, prepared independently by P&E Mining Consultants Inc. in accordance with NI 43-101 and CIM standards. The MRE, effective June 15, 2026, establishes a 164,000 ounce Indicated Mineral Resource (1.62 Mt at 3.16 g/t Au) and a 62,000 ounce Inferred Mineral Resource (0.95 Mt at 2.03 g/t Au). Approximately 73% of the contained gold is classified as Indicated, representing a significant increase in geological confidence.

Table 1. 2026 Tully Gold Project Mineral Resource Estimate with an effective date of June 15, 2026^(1-7).

Notes:

1. Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues. It is noted that no specific issues have been identified yet.
2. The Inferred Mineral Resource Estimate in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.
3. Mineral Resources were prepared in accordance with CIM Definition Standards for Mineral Resources and Mineral Reserves (May 10, 2014) and CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines (Nov 29, 2019).
4. The Qualified Persons are not aware of any known environmental, permitting, legal, title-related, taxation, socio-political, financial, or other relevant issues that could materially affect the MRE.
5. The MRE is reported at a cut off of 1.1 g/t Au for the conceptual underground Deswik™ Stope Optimizer extraction scenario. The cut-off grade and potential mining scenario were calculated using the following parameters; mining cost: $110/t underground mining cost; G&A and site service costs: $15/t; processing cost: $35/t; recovery 92%; gold price US$3,500 per ounce; and minimum stope optimized mining width of 1.25 metres in order to meet the requirement that the Mineral Resources show “reasonable prospects for eventual economic extraction.” US$/C$ exchange rate was 0.72.
6. All prices and costs are in Canadian dollars ($CAD) unless otherwise stated.
7. All numbers are rounded to reflect the relative accuracy of the estimates.

The geological model defines a larger and more continuous underground gold system, with improved geometry that may support underground stopes potentially approaching 20 metres in width. Mineralization remains open along strike and at depth, providing significant potential for Mineral Resource expansion through additional drilling.

The 2026 MRE incorporates modern 3D geological modelling, refined mineralized domains, one-metre compositing, domain-specific grade capping, ID³ interpolation and comprehensive model validation. The model also increases the Indicated Mineral Resource from 93,140 ounces in the 2008 historical estimate to 164,000 ounces, an increase of 76%.

The Technical Report supports the Mineral Resource Estimate independently prepared by P&E Mining Consultants Inc., with Charles Spath, M.Sc., P.Geo., and Eugene Puritch, P.Eng., FEC, CET, serving as independent Qualified Persons under NI 43-101.
