(b) A 0.50% GOR over any additional mineral rights acquired by American West within 5km of the current extents of the Storm Project ("AOI Royalty").

The 0.95% GOR, together with the historical 0.875% GOR over Storm acquired by Taurus from a third party earlier this year, will give Taurus a total 1.825% GOR over Storm. (The historical 0.875% GOR was held by Commander Resources Inc, a previous owner of the Storm Project).

The historical GOR included a buyback right whereby the GOR could be reduced from 0.875% to 0.475% by payment of C$4 million. This buyback right will be cancelled as part of the new royalty arrangements.

Taurus will have the right to match any royalty or streaming transaction associated with the Storm Project up until 12 months following the declaration of commercial production at the Project.

The new royalty arrangements will be documented in formal documentation that will reflect the above commercial terms and will contain such other terms and conditions that are customary for royalty financings of this kind.

About the Storm Copper and Seal Zinc-Silver Projects, Nunavut

The Nunavut property consists of 173 contiguous mining claims covering an area of approximately 219,257 hectares on Somerset Island, Nunavut, Canada. The Storm Project comprises both the Storm Copper Project, a high-grade sediment-hosted copper discovery (intersections including 110m* @ 2.5% Cu from surface and 56.3m* @ 3.1% Cu from 12.2m) as well as the Seal Zinc Deposit (intersections including 14.4m* @ 10.6% Zn, 28.7g/t Ag from 51.8m and 22.3m* @ 23.0% Zn, 5.1g/t Ag from 101.5m). Additionally, there are numerous underexplored and undrilled targets within the 120-kilometre strike length of the mineralized trend, including the Tornado copper prospect where 10 grab samples yielded >1% Cu up to 32% Cu in gossans. The Nunavut property is now the subject of an 80/20 unincorporated joint venture with American West (see "Agreement with American West" below for more details).

Storm Discovery and Historical Work

High-grade copper mineralization was discovered at Storm in the mid-1990s by Cominco geologists conducting regional zinc exploration around their then-producing Polaris lead-zinc mine. A massive chalcocite boulder found in a tributary of the Aston River in 1996 was traced to impressive surface exposures of broken chalcocite mineralization for hundreds of metres of surface strike length at what became named the 2750N, 2200N, and 3500N zones. Subsequent seasons of prospecting, geophysics and over 9,000 m of drilling into the early 2000s confirmed a significant amount of copper mineralization below the surface exposures as well as making the blind discovery of the 4100N Zone, a large area of copper mineralization with no surface exposure.

Following the merger of Cominco with Teck in 2001 and the closure of the Polaris Mine, the Storm claims were allowed to lapse in 2007. Commander Resources staked the property in 2008 and flew a helicopter-borne VTEM survey in 2011 but conducted no additional drilling. Aston Bay subsequently entered into an earn-in agreement with Commander and consolidated 100% ownership in 2015. Commander retained a 0.875% Gross Overriding Royalty in the area of the original Storm claims which was purchased by Taurus Mining Royalty Fund L.P. in January 2024.

In 2016 Aston Bay entered into an earn-in agreement with BHP, who conducted a 2,000-station soil sampling program and drilled 1,951m of core in 12 diamond drill holes, yielding up to 16m* @ 3.1% Cu. BHP exited the agreement in 2017 and retains no residual interest in the project. Aston Bay conducted a property-wide airborne gravity gradiometry survey in 2017 and drilled 2,913m in nine core holes in the Storm area in 2018 yielding a best intercept of 1.5m* @ 4.4% Cu and 20.5m* @ 0.6% Cu.

Agreement with American West

As previously disclosed, Aston Bay entered into an Option Agreement dated March 9, 2021 (the "Option Agreement") with American West Metals Limited and its wholly-owned subsidiary, Tornado Metals Ltd. (collectively, "American West") pursuant to which American West was granted an option (the "Option") to earn an 80% undivided interest in the Project by spending a minimum of CAD$10 million on qualifying exploration expenditures ("Expenditures"). The parties amended and restated the Option Agreement as of February 27, 2023 to facilitate American West potentially financing the Expenditures through flow-through shares but did not change the commercial agreement between the parties.

The Expenditures were completed during the 2023 drilling program and American West exercised the Option in accordance with the terms of the Option Agreement, as amended. American West and Aston Bay have formed a 80/20 unincorporated joint venture and are finalising a joint venture agreement. Under the joint venture, Aston Bay shall have a free carried interest until American West has made a decision to mine upon completion of a bankable feasibility study, meaning American West will be solely responsible for funding the joint venture until such decision is made. After such decision is made, Aston Bay will be diluted in the event it does not elect to contribute its proportionate share and its interest in the Project will be converted into a 2% net smelter returns royalty if its interest is diluted to below 10%.

Recent Work

American West completed a fixed loop electromagnetic (FLEM) ground geophysical survey in 2021 that yielded several new subsurface conductive anomalies. A total of 1,534m were drilled in 10 diamond drill holes in the 2022 season, yielding several impressive near-surface intercepts including 41m* @ 4.1% Cu as well as 68m of sulfide mineralization associated with a deeper conductive anomaly.

In April 2022, results of beneficiation studies demonstrated that a mineralized intercept grading 4% Cu from the 4100N area could be upgraded to a 54% Cu direct ship product using standard sorting technology. Further beneficiation studies are ongoing.

In April 2023, American West embarked on a spring delineation drilling program using a helicopter-portable RC drill rig as well as conducting gravity and moving loop electromagnetic (MLEM) ground geophysical programs.

The summer 2023 program conducted further delineation drilling of the near-surface high-grade copper zones to advance them toward maiden resource estimates by late 2023 or early 2024. Diamond drilling tested new high-priority gravity targets and environmental baseline studies will be initiated.

*Stated drill hole intersections are all core length, and true width is expected to be 60% to 100% of core length.
