Mariposa

Mariposa is 100% owned by Pacific Ridge and comprises 795 claims in the White Gold District of the Dawson Range Mineral Belt, approximately 120 km southeast of Dawson City, 40 km southeast of Golden Saddle and 30 km east-northeast of the Coffee property.

The property is under option to Labrador Gold Corp. under an agreement announced May 11, 2026.

Mariposa’s host rocks, structural controls, brittle deformation and style of gold mineralization are comparable with other White Gold District systems. Prior exploration outlined an open-ended, seven-kilometre horizon of altered, pyrite-bearing quartz-mica schist near the Skookum Zone.

At Hackly, seven quartz-vein and stockwork float samples averaged 2.50 g/t gold and 5.67 g/t silver; the highest sample returned 9.75 g/t gold and 15.7 g/t silver.

• ↳The best reported Skookum Main drill interval is 2.44 g/t gold over 39 m.
• ↳Trenching exposed widespread fractured and oxidized rock with local quartz breccias and veinlets; reported results included 1.25 g/t gold over 30 m within a broader 150 m interval grading 0.493 g/t gold.
• ↳Fourteen of 18 holes at Skookum Main intersected gold mineralization in steeply dipping brittle structures.
• ↳Six high-priority targets—Skookum Main, Skookum West, Big Alex, Maisy Mae, Hackly and Alberta Creek—are defined by gold and multi-element soil anomalies along the Mariposa Fault Zone.

Mariposa lies in the Yukon-Tanana Terrane within the central Dawson Range, part of a regional polymetallic belt associated with Jurassic-to-Cretaceous magmatism. The property is underlain by poly-deformed metamorphic rocks cut by mafic-ultramafic bodies, quartz monzonite and granite intrusions, and feldspar-porphyry dykes.
