LAHONTAN DRILLS 12.2m GRADING 1.25 g/t Au OXIDE AT CALVADA EAST

Toronto Ontario, August 5, 2026 – Lahontan Gold Corp. (TSXV:LG, OTCQB:LGCXF, FSE:Y2F) (the “Company” or “Lahontan”) is pleased to announce additional drill results from its 2026 drilling program at the Santa Fe Mine Project.

The results reported herein comprise seven reverse-circulation (“RC”) drill holes totaling 1,990 metres completed in the Calvada East resource area, the Slab West exploration target and a deep geophysical test located between the Slab and Santa Fe resource areas.

Highlights include the first significant gold mineralization hosted within Tertiary volcanic rocks along the Summit Fault and additional high-grade oxide mineralization at Calvada East. Drill results are summarized below:

• Calvada East: Drill hole CAL26-12R, an RC drill hole originally designed for groundwater monitoring, intersected 12.2 metres (166.1 – 178.3m) grading 1.26 g/t Au Eq oxide (1.25 g/t Au, 0.8 g/t Ag) near the base of the current resource pit shell*, including individual 1.5 metre samples ranging up to 3.29 g/t Au.
• Calvada East: Drill hole CAL26-11R, another RC drill hole originally designed for groundwater monitoring, intersected 13.7 metres (176.8 – 190.5m) grading 1.10 g/t Au Eq (1.01 g/t Au, 7.1 g/t Ag) hosted by Tertiary volcanic rocks within the Summit Fault zone. This represents the first significant gold intercept hosted within Tertiary volcanic rocks at the Santa Fe Mine Project and establishes a new exploration target along the Summit Fault.
• Slab West exploration target: Two RC drill holes at Slab West intersected broad intervals of oxide gold and silver mineralization. CAL26-13R intercepted 35.1m (57.9 – 93.0m) of shallow mineralization grading 0.21 g/t Au Eq (0.19 g/t Au, 1.5 g/t Ag), CAL26-15R cut 18.3m (144.8 –163.1m) grading 0.22 g/t Au Eq (0.21 g/t Au, 0.8 g/t Ag).
