Miramis Mining Corp. Completes Exploration Field Program at Nicola East

Vancouver, British Columbia--(Newsfile Corp. - December 9, 2024) - Miramis Mining Corp. (the "Company") is pleased to provide an exploration update for its Nicola East Mining Project, located approximately 25 km east of the mining town of Merritt, British Columbia. Field crews from Hardline Exploration Corp. completed a multi day prospecting program at the Nicola East Property. The program was aimed to follow up on 2023 results which included a grab sample which returned 3.04 g/t Au in a previously untested area.

Field crews collected 35 samples which included samples from several quartz veins that contained up to 3% chalcopyrite and 1% chalcocite with copper oxide staining. Mineralization was hosted in quartz veins generally <5cm thick with chlorite - epidote alteration. Field crews returned to the location of a qtz-chl vein sampled during the 2023 field season that graded 3.04 g/t Au with the objective of locating and sampling more mineralized veins nearby. The new gold and copper showing highlighted from 2023 sample AA001906 is located at 687807 mE 5555494 mN 10N.

Highlights from the Nicola East Field Program:

• Samples AA002980, AA002983, AA002984, F00066262 and F00066263 all contained visible Cu mineralization.
• Mineralization and quartz veins with euhedral crystal growth dissipated farther out from the 3.04 g/t Au sample.
• Lithology consisted of grey/green andesitic volcanics often with medium grained hornblende phenocrysts.
• Pervasive chlorite alteration was noted in the andesitic volcanics. Epidote alteration occurred primarily adjacent to qtz veins.
• 35 samples were taken in total.
• QAQC samples included 2 certified reference material standards and 1 certified blank.
