Nicola Mining Announces Plan for 2026 Drilling Exploration at Treasure Mountain Silver Project

Vancouver, British Columbia--(Newsfile Corp. - October 15, 2025) - Nicola Mining Inc. (TSXV: NIM) (OTCQB: HUSIF) (FSE: HLIA) (the "Company" or "Nicola") is pleased to provide an update on preparation work conducted during 2025 on the Treasure Mountain Silver Project ("Treasure Mountain") and its plan for 2026 exploration drilling program ("2026 TM Program"). The 2026 TM Program is the culmination of an airborne magnetic geophysical survey (conducted by Scott Hogg & Associates Ltd. in 2012), extensive soil sampling programs over multiple years, and 2025 field reconnaissance. Treasure Mountain is a permitted silver mine located 30 km northeast of Hope and about a 3-hour drive from Vancouver, British Columbia. Treasure Mountain was an operating mine but was put into care and maintenance in 2013^[1], due to depressed silver prices and has always been a core asset to Nicola, which has been strategically waiting for higher silver prices.

As previously announced in the Company's June 9, 2025 news release, Nicola received a multi-year area-based exploration permit (the "MYAB Permit"), allowing the Company to conduct diamond drilling and trenching at Treasure Mountain. In addition to receipt of MYAB Permit, the Company received a ten year mine lease extension (through April 26, 2032; announced on August 30, 2024), further bolstering the attractiveness of re-opening Treasure Mountain.

The area of exploration interest is northwest of the currently suspended mine (Fig. 1) and consists of several northeast-southwest trending and steeply dipping sulphide-rich veins (Fig. 2). Photos exhibited in Figure 2 are associated with 2025 field reconnaissance focused on establishing the 2026 TM Program drill targets.

Initial interest in this area was driven by Coeur Mining's ("Coeur")^[2] (NYSE: CDE) (TSX: CDM) 2012 investment into the Company giving it a 12.7% ownership at time of investment. Coeur purchased shares at a price of $1.08 ($20.6 when considering subsequent rollbacks)^[3].

Previous exploration work along this trend is limited to six percussion holes totaling 274m in 1994 and 14 "backpack drill" holes totaling 25m in 2020. Widespread soil sampling was also conducted in 2019 and 2020. Limited rock samples were collected in 2020 and 2021. The most recent exploration along this trend (sampling conducted by Nicola in 2021) is described in Assessment Report #39721 (available on ARIS^[4]). Results from these programs are encouraging and demonstrate the presence of vein-hosted silver, copper, lead, zinc and gold. This provides support for initial diamond drilling to establish the width of the trend and mineralization at depth. Currently mineralization is present on surface and open in all directions.
