Nicola Mining Commences First-Ever Drill

Program at Treasure Mountain's MB Zone and

Reports Intense Mineralization

Vancouver, British Columbia--(Newsfile Corp. - September 18, 2026) - Nicola Mining Inc. (NASDAQ:

NICM) (TSXV: NIM) (FSE: HLIA) (the "Company" or "Nicola") is pleased to announce that it has

commenced its 2026 exploration drilling program (the "2026 TM Program") at Treasure Mountain.

Treasure Mountain is a permitted silver mine located approximately 30 km northeast of Hope, British

Columbia, and roughly a three-hour drive from Vancouver. The mine was placed on care and

maintenance in 2013 during a period of depressed silver prices. Notwithstanding the suspension of

mining operations, Treasure Mountain has remained a core asset within Nicola's portfolio, with the

Company maintaining the project in anticipation of a more constructive silver-price environment and an

appropriate opportunity to advance systematic exploration.

The 2026 TM Program includes diamond drilling at the MB target area, a previously undrilled zone

approximately 1 km northwest of the historical Treasure Mountain silver mine (

Figure 1

). The Company

considers the MB target area a compelling exploration target for high-grade silver-lead-zinc

mineralization similar to that encountered at the historical mine, with the additional presence of copper

and gold. From 2019 to 2022, Nicola carried out soil and surface rock sampling that returned

encouraging results indicating silver-lead-zinc-copper-gold mineralization along a vein system exposed

at several locations along strike.

Encouraging results from the 2019/2020 sampling programs include:

Sample 2100151: 813 g/t Ag, 0.52 g/t Au, 19% Zn and 4.66% Cu;

Sample 2100152: 105 g/t Ag and 1.18% Cu; and

Sample 2100207 (taken from the exposed vein): 1,300 g/t Ag, 2.59 g/t Au, 1.16% Cu, 27.4% Pb

and 27.2% Zn.

Drilling for the 2026 season is expected to be completed by the end of September, with assay results

expected to be released by year-end.

The 2026 TM Program comprises four drill holes totaling approximately 800 m and targeting the MB

Zone, an area characterized by mineralized veins at surface that has not previously been drill-tested at

depth. The Company is working with Western Exploration Diamond Drilling Ltd. to execute the 2026 TM

Program. The holes are designed to intersect and test previously sampled quartz-sulphide veins trending

northeast-southwest along the length of the valley.

Core from the first hole is being sampled and submitted to AGAT Laboratories for multi-element

analysis. Visual examination of the core has identified intervals exhibiting intense mineralization,

examples of which are shown in

Figure 2

. While these observations are geologically encouraging, visual

estimates are not a substitute for analytical results. The Company will report assay results following

receipt, verification and review in accordance with its disclosure procedures.

patches and sulphide-rich aggregates throughout the host rock. Pyrrhotite and pyrite are predominant,

with subordinate sphalerite occurring as coarse, silvery-grey blebs and aggregates.

CEO COMMENT

Peter Espig, Chief Executive Officer of Nicola Mining, commented: "Treasure Mountain has remained a

vital component of Nicola's asset portfolio throughout a prolonged period in which silver-market

conditions did not justify aggressive capital deployment. Commencing drilling at the MB Zone marks a

deliberate transition from asset preservation to value-oriented exploration. We are particularly

encouraged by the intensity of mineralization observed in the first drill core; however, our interpretation

will remain disciplined, and assay driven. The 2026 TM Program was designed to test whether

mineralized surface veins demonstrate continuity and scale at depth. Positive analytical results would

materially enhance our geological understanding of the MB Zone and help define the next phase of

exploration at Treasure Mountain."
