Coeur Mining, Inc. has announced the initial results of its 2024 exploration program at the Silvertip polymetallic critical minerals project in northern British Columbia. This marks the most comprehensive surface exploration effort undertaken by Coeur since acquiring the property in 2017, comprising 48 drill holes, a total investment of $12 million, and over 21,000 meters (68,326 feet) of drilling.

The primary objectives of the program were to:

(i) expand the known resource by drilling from underground to enhance mineralization along strike and down-dip;

(ii) undertake large step-out drilling on major structural features to increase the deposit’s footprint for future resource expansion; and

(iii) conduct district-scale fieldwork to identify new structural targets that may host significant ore bodies. Early results have demonstrated success across all these initiatives, particularly with a notable expansion of the Southern Silver Zone's strike length to over 2,000 meters and the identification of three new high-priority exploration targets.

Mitchell J. Krebs, Coeur's Chairman, President, and CEO, stated, “Our multi-faceted 2024 exploration strategy has successfully extended known areas of mineralization and doubled the strike length of the Southern Silver Zone. We are confident in Silvertip’s potential to become a future source of critical minerals and to drive growth for the Company.”

The district-scale exploration has led to the identification of three new targets, which exhibit geological similarities to the Silvertip Carbonate Replacement Deposit (CRD). These findings, combined with geophysical surveys conducted over 37,000 hectares, have highlighted areas with promising mineralization characteristics. As a result, Coeur has expanded its land position by securing an option on an additional 10,000 hectares of prospective ground adjacent to the Silvertip property, under a partnership with CMC Metals Ltd.

Underground drilling, conducted from March to October, was focused on moderate step-outs adjacent to the existing resource areas in the Saddle and Southern Silver Zones, encountering promising mineralization. Surface drilling between July and November concentrated on extending the Southern Silver Zone, with five diamond drill holes completed, all intersecting significant mineralization. Assay results from these holes have confirmed mineralized intervals up to 1,000 meters beyond the current resource boundary.

Fieldwork conducted as part of the district-scale exploration program involved geological mapping, geochemical rock and soil sampling, and stream sediment surveys. These efforts have identified three key target areas—Berg, Weiram Mountain-Hamlet Mountain, and Brinco Hill—with geological settings consistent with the Silvertip deposit. These areas show promising indications of potential new CRD-style mineralization.

Coeur Mining remains optimistic about the continued exploration success in 2025, anticipating further discoveries and resource growth at Silvertip, positioning the project as a key source of critical minerals in the global supply chain.
