EAGLE PLAINS PARTNER EARTHWISE COMMENCES DRILL PROGRAM AT THE IRON RANGE PRECIOUS METALS PROJECT, SE BC

Eagle Plains Resources Ltd. partner Earthwise Minerals Corp. has commenced a diamond drilling program at Eagle Plains' 100-per-cent-owned Iron Range project in southeastern British Columbia. Earthwise holds the exclusive option to acquire up to an 80-per-cent interest in the Iron Range project.

The 20,021-hectare Iron Range project is considered by management of both Eagle Plains and Earthwise to hold excellent potential for the presence of structurally controlled gold-silver mineralization, iron oxide copper/gold (IOCG) and Sullivan-style lead-zinc-silver sedimentary exhalative (sedex) mineralization. The property is owned 100 per cent by Eagle Plains, with part of the property subject to an underlying 1.0-per-cent net smelter royalty (NSR) held by a third party. The drill program will be managed by Terralogic Exploration Inc.

The 2026 drill program will target the Talon zone structure, where 2010 drilling by Eagle Plains intersected two intervals of strong and continuous mineralization, including 14.0 metres grading 5.1 grams per tonne gold, 1.86 per cent lead, 2.1 per cent zinc and 75.3 grams per tonne silver and 7.1 metres grading 8.13 grams per tonne gold, 2.84 per cent lead, 3.07 per cent zinc and 86.6 grams per tonne silver (DDH IR10-010).

Two of the three holes will crosscut the Talon zone structure and are designed to infill gaps in the historic drilling. The third hole will test downdip and along strike of known mineralization, targeting a coincident resistivity-conductivity induced polarization (IP) anomaly.

Chuck Downie, president and chief executive officer of Eagle Plains, commented: "We are excited to be back drilling at the Iron Range project with our partners Earthwise. The Talon zone is a high-grade gold-mineralized shear proximal to a major regional structure. The presence of similar structural splays off of the Iron Range fault system, coincident with anomalous pathfinder geochemistry and IP geophysical anomalies that are modelled to extend to depth indicate the potential for additional Talon-zone-style mineralization at the project."

Iron Range project summary

The 20,021-hectare Iron Range project located near Creston, B.C., is owned 100 per cent by Eagle Plains, subject to a 1-per-cent NSR held by a third party on a portion of the claim group. A well-developed transportation and power corridor transects the southern part of the property, including a high-pressure gas pipeline and a high-voltage hydroelectric line, both of which follow the CPR (Canadian Pacific Railway) mainline and Highway 3. The rail line provides efficient access to the Teck smelter in Trail, B.C. The project is fully permitted with a multiyear area-based (MYAB) permit in place issued by the British Columbia Ministry of Mining and Critical Minerals that includes provisions for geophysical work, mechanical trenching, access trail construction and diamond drilling.

The Iron Range property covers an extensive area approximately 10 kilometres by 32 kilometres, which overlies the regional Iron Range fault system (IRFS). Prior to the acquisition by Eagle Plains in 2001, the property had seen little systematic exploration for other than iron resources known to exist on the property since the late 1800s. Since 2001, Eagle Plains and its partners have completed 21,593 metres of diamond drilling in 87 holes, collected 2482 line kilometres of airborne and surface geophysical data, and analyzed 10,053 soil geochemical samples, 495 rock samples and 6,955 drill core samples.

Drilling at Iron Range in 2010 resulted in the discovery of the Talon zone, where drill hole IR10-010 intersected two intervals of strong and continuous mineralization, including 14.0 metres grading 5.1 grams per tonne gold, 1.86 per cent lead, 2.1 per cent zinc and 75.3 grams per tonne silver and 7.1 metres grading 8.13 grams per tonne gold, 2.84 per cent lead, 3.07 per cent zinc and 86.6 grams per tonne silver (see Eagle Plains' news release dated Dec. 21, 2010). Previous drilling 10 kilometres north of the Talon zone in 2008 by Eagle Plains intersected gold mineralization in drill hole IR08006, which assayed 7.0 metres grading 51.52 grams per tonne (1.50 ounces per ton) gold (see Eagle Plains' news release dated April 20, 2009).

Mineralization at the Pyromorphite zone (British Columbia Minfile 082FSE141) was discovered in 2009 after construction of logging roads exposed sheared and brecciated sediments hosting centimetre-scale quartz veins bearing pyromorphite (lead) mineralization. No significant work has been completed at the zone since its initial discovery by the previous tenure holder. Rock (grab) sample SK10-207 reports 27.0 grams per tonne gold, 173.0 grams per tonne silver and 13.4 per cent lead (British Columbia assessment report 31659). Rock (grab) sample MK10-170 reports 54.7 grams per tonne gold, 42.2 grams per tonne silver and 2.8 per cent lead (British Columbia assessment report 31659). Fieldwork in 2025 at the Pyromorphite zone returned up to 13.4 grams per tonne gold, 27.2 grams per tonne silver, greater than 10,000 parts per million arsenic and 2.7 per cent lead from an in situ grab sample (KBBIRR004) (see Eagle Plains' news release dated Nov. 17, 2025). The polymetallic (arsenic-lead-zinc) nature of the mineralization at the Pyromorphite zone and the association between arsenopyrite and gold mineralization are consistent with the structurally hosted mineralization that defines the Talon zone target 12 kilometres to the southwest.

Rock grab samples are selective samples by nature and as such are not necessarily representative of the mineralization hosted across the property. Some of the above results were taken directly from Minfile descriptions and assessment reports (ARIS) filed with the British Columbia government. Management cautions that historical results were collected and reported by past operators and have not been verified nor confirmed by a qualified person but form a basis for continuing work on the subject properties. Management cautions that past results or discoveries on proximate land are not necessarily indicative of the results that may be achieved on the subject properties.

Iron Range option agreement details

To exercise the option, Earthwise must make a series of cash payments and share issuances to Eagle Plains and finance exploration expenditures on the project. These payments, share issuance and expenditures are separated into two phases, with the first option entitling the company to acquire a 70-per-cent interest in the project by paying $250,000, issuing an aggregate of 1.5 million common shares to Eagle Plains and financing $4-million in exploration expenditures on the project by over a four-year term. Pursuant to the second phase of the option, the company may acquire an additional 10-per-cent interest in the project (for an 80-per-cent total interest) by notifying Eagle Plains of its intent to increase its interest to 80 per cent, making an additional one-time payment of $1-million cash and completing a bankable feasibility study on the property, before the eighth anniversary of the option.

If the first option or the second option is exercised, a 2-per-cent smelter return royalty will be granted to the Eagle Plains over the entire property, 1 per cent of which may be repurchased for $1.5-million.

Eagle Plains will serve as operator under the terms of option and will reserve the right to use Terralogic Exploration Inc. as geoscience consultant. Following the exercise of either the first or second option, Earthwise and Eagle Plains shall then form a 70/30 or 80/20 joint venture to further explore and develop the property.
