Forge Resources Defines Late Cretaceous Porphyry Mineralization at the Alotta Project
Vancouver, May 5, 2026 - Forge Resources Corp. (CSE: FRG) (OTCQB: FRGGF) (FSE: 5YZ) ("FRG" or the "Company") is pleased to announce the results of new Re-Os ages and geochemical findings from at the Alotta Project, Yukon (Figure 1). Analyses of Re-Os of molybdenite confirm a Late Cretaceous age for porphyry mineralization at the Alotta Project, which is consistent with major porphyry and epithermal deposits in the Dawson Range Gold Belt, including the Casino deposit.
Highlights:
- Similar ages as the Casino Cu-Au-Mo deposit - Molybdenite dating from porphyry-style veins at the Severance (72.8 Ma) and Commission (73.1 Ma) zones are consistent with the timing of porphyry mineralization at Western Copper and Gold's Casino deposit (~74 Ma).
- Re-Os dates from molybdenite at Alotta are consistent with other significant Late Cretaceous Porphyry and Epithermal deposits in the Dawson Range Gold Belt, including Triumph Gold Corp.'s Revenue deposit, Rockhaven Resources' Klaza deposit and the Cash deposit.
- Geochemical analyses indicate the mineralized porphyries at Alotta formed under similar oxidizing conditions to the major Late Cretaceous deposits in the Dawson Range Gold Belt, strengthening the notion that the system underlying the Alotta Project formed in similar geologic environments.
PJ Murphy, CEO of Forge Resources, states: "This data is exciting as now we can say for certain we are exploring a Late Cretaceous system capable of forming potentially significant amounts of copper and gold, similar to many of the major porphyry and epithermal systems occurring in the prolific Dawson Range. With additional technical studies and drill planning currently underway, we think 2026 will be a formative year for the Alotta Project and look forward to updating the market as we further develop targets and exploration plans for this year."
With support from the Yukon Geological Survey, core samples were collected from the Severance and Commission zones in late 2025 to date the age of porphyry-style mineralization at the Alotta Project (Table 1, Figure 1). Re-Os dating of molybdenite from drill core confirms the porphyry-style mineralization is Late Cretaceous, consistent with established ages for the nearby Casino deposit and other significant porphyry and epithermal deposits in the Dawson Range Gold Belt (Table 2, Figure 2).

Geochemical studies conducted alongside Re-Os geochronology indicate that the mineralized porphyry intrusions at Alotta formed under oxidizing conditions and exhibit geochemical characteristics typical of copper- and gold-bearing Late Cretaceous intrusions, including the Casino deposit and other porphyry and epithermal deposits in the Dawson Range Gold Belt (Figure 3).

Forge Resources is advancing detailed systematic technical studies and analyses on the project, utilizing the specialized expertise of the Company's geological contractor, Archer Cathro. Additionally, the Company has contracted in3D Geoscience Inc. to reprocess geophysical data collected on the property, including a property wide magnetic inversion. This work is currently underway and will provide important data to guide target generation and drill planning. Updates on these studies and drill planning will be announced as they are completed.
Proximity to Measured and Indicated Resources
The Alotta property consists of 230 mineral claims that covers approximately 4,723 hectares in a similar geological setting to Western Copper and Gold's Casino deposit, that is located 50 km to the north of the Alotta Project. The Casino deposit is one of the largest undeveloped copper-gold porphyry projects in the world.
About Forge Resources Corp.
Forge Resources Corp. is a Canadian-listed junior exploration company focused on exploring and advancing the Alotta project, a prospective porphyry copper-gold-molybdenum project consisting of 230 mineral claims that cover 4,723 hectares, located 50 km south-east of the Casino porphyry deposit in the unglaciated portion of the Dawson Range porphyry/epithermal belt in the Yukon Territory of Canada.
In addition, the Company holds an 80% interest in Aion Mining Corp., a company that is developing the fully permitted La Estrella coal project in Santander, Colombia. The project contains eight known seams of metallurgical and thermal coal.
