Loyalist Exploration Completes Preliminary Review of DeSantis Gold Property

Toronto, Ontario — April 23, 2026 — Leads & Copy — Loyalist Exploration Limited has completed a preliminary review of its DeSantis gold property, identifying six priority targets and an additional target on the McEnaney claims. The DeSantis property is located approximately 4.5 kilometers southwest of Timmins, Ontario.

The company has also identified historical progress reports from 1963–1964 referencing the New Hope Porcupine (DeSantis) property. These reports include historical tonnage estimates and sample results prepared in support of a contemplated restart. Loyalist cautions that these historical estimates are not current and have not been verified.

The preliminary review of the DeSantis property highlighted six priority targets in and around the historic DeSantis Mine workings. The 1963–1964 historical progress reports reference the New Hope Porcupine (DeSantis) property and include historical tonnage estimates that are non-NI 43-101 compliant, not current, not verified and not to be relied upon.

The review also found a shallow up-dip extension of the Albitite Zone from surface to the 800-foot level with the potential to add resources to the property. A possible parallel gold zone above the Albitite Zone includes an intersection of 25.0 g/t Au over 0.61 m.

Loyalist also noted a depth extension of the Albitite Zone as a high-priority exploration target, as well as a west extension of the Hydrothermal Zone supported by historical drill intercepts.

Notable historical intercepts include 7.54 g/t Au over 1.52 m and 3.26 g/t Au over 1.25 m on the McEnaney claims. The review was based on 488 drill holes totaling 101,945.4 m and 21,158 gold assays.

Loyalist’s President & Chief Executive Officer Errol Farr said that the six significant targets and mineralization left in the historic workings make DeSantis a compelling exploration property with significant untapped potential along the Destor-Porcupine corridor. The next step is to conduct a more detailed review and mapping of the historic workings and creation of a summer work program.

The DeSantis property is situated 11 km west of Discovery Silver’s Dome Mine and 14 km east of Pan American Silver’s Timmins Mine. It covers nearly 5 km of strike length along the north side of the Destor-Porcupine Deformation Zone. Between 1926 and 1943, the DeSantis Mine produced 35,784 oz. of gold, 3,142 oz. of silver and 193 lb. of scheelite from 196,928 tons of material at an average mill head grade of 0.19 oz/ton Au.

A historical non-NI 43-101 compliant resource estimate totaling 182,505 tonnes at 8.64 g/t Au was completed across the Albitite and Hydrothermal Zones. Investors are cautioned not to rely on this historical estimate as a current mineral resource.

An initial review of a historical database acquired by the Company included 488 drill holes totalling 101,945.4 m, 21,158 gold assays from core samples, wireframes of historical underground mine workings and wireframes of the Hydrothermal and Albitite Zones.

Two main gold-mineralized domains have been historically recognized at the DeSantis Mine: the Albitite Zone and the Hydrothermal Zone.

The preliminary review identified six priority targets in and around the DeSantis Mine, plus an additional target on the McEnaney claims to the east.

All drill intercepts referenced are historical, have been sourced from a database acquired by the Company, and have not been independently verified. Reported widths are downhole intervals; true widths are not known. Investors are cautioned not to rely on these historical data as current.

The historical tonnage and grade figures disclosed in respect of the New Hope Porcupine (DeSantis) property are taken from Progress Reports authored by Grant and Oja Limited on behalf of Kenilworth Mines Limited, and filed under Timmins File T-140 with the Ontario Ministry of Mines. The tonnage estimates are attributed in those reports to W.R. Dunbar.

Loyalist views the 1963–1964 T-140 reports as providing useful additional historical context for the exploration potential of the New Hope Porcupine (DeSantis) property.

Collar coordinates, orientation, and total length for the historical drill holes referenced in the target descriptions are summarized in Table 1 of the original release.

The historical Mineral Resource Estimate on the DeSantis Property is unclassified and does not comply with CIM Definition Standards. Investors are cautioned not to treat the estimate as current or rely on the estimate in making an investment decision.
