RUMBLE RESOURCES EXPANDS WILMAC COPPER-GOLD PROJECT TO 11,504 HECTARES WITH ADDITION OF LAMONT RIDGE AND PLUME

Rumble Resources Inc. has expanded its Wilmac copper-gold project within the Quesnel porphyry belt in the Similkameen mining division of British Columbia. By an agreement executed Oct. 8, 2025, the company has amended the option agreement announced June 11, 2025, to include the contiguous Lamont Ridge and Plume areas, increasing the project from 2,355 hectares to 11,504 hectares.

Project expansion highlights:

• Lamont Ridge: seven claims totalling 7,086 hectares, adjoining Wilmac to the north and south, and located approximately 10 kilometres (km) west of Hudbay Minerals Inc.'s Copper Mountain mine. Historical and 2024 infill soils outline extensive copper anomalies; a 3-D induced polarization (IP)/audio-frequency magnetotellurics (AMT) survey delineates two interpreted parent intrusions with pipe-like features to surface;
• Plume (application pending): one mineral title application totalling 2,063 hectares (ha) adjoining Wilmac to the south; covers two iron-carbonate-silica alteration zones, one spatially associated with a small diorite-gabbro exposure. The application is being processed under B.C.'s tenure system adopted in March, 2025, which requires, among other things, consultation with first nations before mineral claims may be registered;
• Targeting: priority targets include the Rice Stock, West Lamont Complex and Fourteen-Fifteen Mile Creek complex, each associated with mapped mafic-intermediate intrusions and strong magnetic responses consistent with porphyry-style systems. Readers are cautioned that the presence of an adjacent producing mine is not necessarily indicative of mineralization on Wilmac.

Lamont Ridge technical summary

A 3-D IP/AMT survey completed in late 2024 is interpreted to outline two parent intrusives with several upward-extending pipes. Soil sampling (including 97 additional samples north of the Lamont grid) returned 66 samples above 100 parts per million (ppm) copper, to a maximum of 1,125 ppm copper, broadly correlating with near-surface high-chargeability and deeper conductivity anomalies on the east side of the property.

Amended option terms

Under the amended terms, the company will pay an additional $370,000 in cash and issue 2.0 million units at a deemed price of 30 cents. Each unit consists of one common share and one transferable common share purchase warrant. Each warrant entitles the holder to purchase one common share at 30 cents for 24 months from issuance. Securities are subject to a four-month-and-one-day hold and applicable regulatory approvals.

In aggregate, to earn a 70-per-cent interest in Wilmac (Wilmac, Lamont Ridge and Plume, if and when granted), the company must make $700,000 in cash payments over three years ($25,000 paid), issue 1.0 million units at 10 cents (issued) and 2.0 million units at 30 cents, and incur $3.99-million in exploration expenditures over five years. The project is subject to a 2-per-cent net smelter return royalty, of which 1 per cent may be repurchased for $2.0-million. Following exercise of the option, $100,000 in annual advance royalty payments are payable.
