ROTTENSTONE GOLD INC. - CORPORATE UPDATE

Rottenstone Gold Inc. has provided a corporate update.

Rottenstone project update

The issuer has evaluated recent public announcement by Ramp Metals Inc. pertaining to certain follow-up results at their Rottenstone SW project (see Ramp Metals news release, Ramp Metals Confirms VMS Discovery at Rush target, dated Aug. 5, 2025). The corporation notes that volcanogenic massive sulphide (VMS) deposits are often formed in clusters within a regional area, and Rottenstone Gold holds a material share of the claim licences in the broader area near Ramp Metals' Rush target.

The corporation is also monitoring the subsequent market response involving Ramp Metals' equity price following their aforementioned news release (same being dated Aug. 5, 2025), preliminary evaluation of which is interpreted by the issuer as generally being less constructive to capital inflows to the Rottenstone domain from a gold exploration perspective but prospectively conducive toward copper exploration by way of the issuer's substantial regional control of disposition licences in area related to the northwest corner of its Rottenstone project, including as relates to any potential VMS cluster that may emerge, noting again the context that VMS deposits may occur within a clustered (or regional) setting. The issuer is currently a large disposition holder in the Rottenstone domain and its surrounding area.

Subsidiary development

The corporation also reports that effective Aug. 8, 2025, it has acquired Silver Royalties Corp., with a view to evaluating silver-related opportunities. As a result, Rottenstone Gold owns 100 per cent of Silver Royalties, with said entity now being a subsidiary of the issuer.

The issuer reimbursed a control person of the issuer for the incorporator's sole common share of Silver Royalties through a purchase-and-sale agreement, at a prescribed $1.00 sum. Silver Royalties does not presently have any material assets nor any liabilities.

The issuer anticipates that it will launch a branded website for its new wholly owned subsidiary to be located at the Silver Royalties website in due course.
