Prismo’s Interest Currently Stands at 95% With Option for Full Control

Vancouver, British Columbia, January 16th, 2025 TheNewswire – Prismo Metals Inc. (‘Prismo’ or the ‘Company’) (CSE: PRIZ,OTC:PMOMF) (OTCQB: PMOMF) is pleased to announce that it has completed its previously announced transaction with Infinitum Copper Corp. (TSXV: INFI) (‘Infinitum’) whereby Prismo has increased its interest in the Hot Breccia copper project, located in the heart of Arizona’s prolific copper belt, from 75% to 95%. In addition, Prismo has obtained an irrevocable option to acquire Infinitum’s remaining 5% interest, providing a clear path to 100% interest in the project.

Alain Lambert, CEO of Prismo commented: ‘This transaction marks a significant milestone for Prismo and provides a clear mechanism to securing full ownership of Hot Breccia. It materially improves the strategic flexibility of the project.’

He added: ‘Prismo remains firmly committed to advancing Hot Breccia. The recent extension of certain milestone obligations under the option agreement with Walnut Mines LLC, the owner of the Hot Breccia claims, together with the completion of the transaction with Infinitum, provides the Company with additional flexibility as we evaluate a range of strategic alternatives. Each of these pathways’ goal is to drill what we consider to be one of the most compelling copper exploration opportunities in Arizona and the broader United States.‘

Dr. Linus Keating, manager of Walnut Mines LLC, enthusiastically commented: ‘Walnut Mines is solidly in favor of any action that moves Hot Breccia closer to a serious drill program. We are hopeful that this transaction will accomplish that goal in 2026. In our opinion, this property remains one of the best copper exploration opportunities in North America.’

Under the terms of the transaction, Prismo paid Infinitum CA $185,000 to acquire a 20% additional interest in the Hot Breccia project and assumed all of Infinitum’s remaining obligations under the existing option agreement with Walnut to issue shares to Walnut, which has been satisfied by the issuance to Walnut of 450,630 common shares at a deemed issue price of $0.11 per share. Prismo has also agreed to pay Infinitum 5% of any consideration received in connection with a transaction in which Prismo assigns its interest in Hot Breccia to a third party to acquire the 5% interest held by Infinitum.

Prismo‘s Hot Breccia project lies at the heart of the Arizona Copper Belt, which hosts several globally significant porphyry copper deposits.  Examples of these significant deposits are Freeport McMoRan’s Miami-Inspiration mining complex, BHP’s San Manuel mine, Rio Tinto and BHP’s Resolution deposit and others (see Figure 1).

Osisko Metals Incorporated (the ‘Company’ or ‘Osisko Metals’) (TSX: OM,OTC:OMZNF; OTCQX: OMZNF; FRANKFURT: 0B51) is pleased to announce new drill results from the Gaspé Copper Project, located in the Gaspé Peninsula of Eastern Québec.

New analytical results are presented below (see Table 1), including 35 mineralized intercepts from ten new drill holes. Infill intercepts are located inside the 2024 MRE model (see November 14, 2024 news release), and are focused on upgrading inferred mineral resources to measured or indicated categories, as applicable. Expansion intercepts are located outside the 2024 MRE model and may potentially lead to additional resources that will be classified appropriately within the next MRE update. Some of the reported intercepts have contiguous shallower infill as well as deeper expansion (noted on Table 1 below as ‘Both’). Maps showing hole locations are available at www.osiskometals.com.

Highlights:

• Drill hole 30-1144
  • 748.0 metres averaging 0.27% Cu (0.37% CuEq – infill and expansion)
• Drill hole 30-1146
  • 729.0 metres averaging 0.21% Cu (0.29% CuEq – infill and expansion)

** ‘Both’ indicates drill holes that have contiguous shallower infill as well as deeper expansion intercepts.

Discussion

Drill hole 30-0881, located on the western margin of the Copper Mountain pit, was a historical hole that was re-analyzed from available core to include sections that had not been previously assayed. New results added three new significant mineralized intervals (expansion) including 62.5 metres averaging 0.29% Cu, 2.20 g/t Ag and 0.020% Mo, followed by 45.4 metres averaging 0.20% Cu and 1.67 g/t Ag and an additional 421.8 metres averaging 0.28% Cu, 1.24 g/t Ag and 0.026% Mo. The last portion of 144.4 metres of the latter intersection confirmed previously reported results, and this historical hole will now constitute a depth expansion in the upcoming MRE update.

Drill holes 30-1132 and 30-1137, located near the eastern margin of the 2024 MRE model, cut multiple intersections of mineralization, 15 to 125 metres thick and distributed in ‘layer cake’ fashion from surface, including 125.2 metres averaging 0.20% Cu, 1.25 g/t Ag and 0.009% Mo (expansion in 30-1137), extending mineralization in this area to vertical depths of 783 and 851 metres, respectively.

Drill hole 30-1135, located in the south-central portion of the 2024 MRE model, cut multiple intersections of mineralization, 26 to 201 metres thick and distributed in ‘layer cake’ fashion from surface, including a deeper intersection of 201.0 metres averaging 0.20% Cu, 1.59 g/t Ag and 0.026% Mo (expansion), extending mineralization in this area to a vertical depth of 729 metres.

Drill hole 30-1141, located on top of Copper Mountain near the centre of the 2024 MRE model and inclined 61 degrees to the north, cut 171.5 metres averaging 0.42% Cu and 3.12 g/t Ag (infill) as well as multiple short 10 to 28 metre intersections to a depth of 695 metres.

Drill hole 30-1142, located near the southwestern lip of the Copper Mountain open pit, cut one mineralized interval of 585.0 metres averaging 0.24% Cu, 0.96 g/t Ag and 0.017% Mo (infill and expansion), followed by 245.0 metres averaging 0.55% Cu, 2.25 g/t Ag and 0.035% Mo (expansion). This hole confirmed mineralization in this area to a vertical depth of 1006 metres.

Drill hole 30-1143, located 50 metres south of the southern margin of the 2024 MRE model in the Southern Extension Zone, cut 163.5 metres averaging 0.47% Cu and 3.41 g/t Ag followed by 48.0 metres averaging 0.67% Cu and 6.15 g/t Ag, once again confirming the higher copper and silver grades of mineralization in this zone.

Drill hole 30-1144, located on the western flank of Copper Mountain and inclined 67 degrees to the north, cut two mineralized intervals including 40.0 metres averaging 0.23% Cu and 1.70 g/t Ag (infill) followed by 748.0 metres averaging 0.27% Cu, 1.84 g/t Ag and 0.023% Mo (infill and expansion), extending mineralization in this area to a vertical depth of 895 metres.

Drill hole 30-1145, located between holes 30-1135 and 30-1137, cut five intersections of mineralization, 28 to 57 metres thick and distributed in ‘layer cake’ fashion from surface to a depth of 462 metres (all infill), followed by 149.3 metres averaging 0.15% Cu, 1.11 g/t Ag and 0.016% Mo (expansion) and 52.3 metres averaging 0.18% Cu, 1.24 g/t Ag and 0.024% Mo (expansion), extending mineralization in this area to a vertical depth of 770 metres.

Drill hole 30-1146, located on top of Copper Mountain near the centre of the 2024 MRE, cut 192.0 metres averaging 0.31% Cu and 2.36 g/t Ag (infill) followed by 135.0 metres averaging 0.13% Cu, 1.02 g/t Ag and 0.014% Mo (infill) and then 729.0 metres averaging 0.21% Cu, 1.48 g/t Ag and 0.019% Mo (infill and expansion), extending mineralization in this area to a vertical depth of 1152 metres.

Mineralization at Gaspé Copper is of porphyry copper/skarn type and occurs as disseminations and stockworks of chalcopyrite with pyrite or pyrrhotite and minor bornite and molybdenite. One prograde and at least five retrograde vein/stockwork mineralizing events have been recognized at Copper Mountain, which overprint earlier, bedding replacement skarn and porcellanite-hosted mineralization throughout the Gaspé Copper system. Porcellanite is a historical mining term used to describe bleached, pale green to white potassic-altered hornfels. Subvertical stockwork mineralization dominates at Copper Mountain whereas prograde bedding-parallel mineralization, which is mostly stratigraphically controlled, dominates in the area of lower Copper Mountain, Needle Mountain, Needle East, and Copper Brook. High molybdenum grades (up to 0.5% Mo) were locally obtained in both the C Zone and E Zone skarns away from Copper Mountain.

The 2022 to 2024 Osisko Metals drill programs were focused on defining open-pit resources within the Copper Mountain stockwork mineralization (see May 6, 2024 MRE press release). Extending the resource model south of Copper Mountain into the poorly-drilled prograde skarn/porcellanite portion of the system subsequently led to a significantly increased resource, mostly in the Inferred category (see November 14, 2024 MRE press release).

The current drill program is designed to convert the November 2024 MRE to Measured and Indicated categories, as well as test the expansion of the system deeper into the stratigraphy and laterally to the south and southwest towards Needle East and Needle Mountain respectively. The November 2024 MRE was limited at depth to the base of the L1 skarn horizon (C Zone), and all mineralized intersections below this horizon represent potential depth extensions to the deposit, to be included in the next scheduled MRE update in Q1 2026.

Most holes are being drilled sub-vertically into the altered calcareous stratigraphy that dips 20 to 25 degrees to the north. The L1 (C Zone) the L2 (E Zone) skarn/marble horizons were intersected in most holes, as well as intervening porcellanites that host the bulk of the disseminated copper mineralization.

HIGHLIGHTS:

• Production guidance of 50,000-55,000 oz gold
• Cash Costs of $1,850-$1,950/oz gold and All In Sustaining Costs of $2,025-$2,125/oz gold
• Pre-stripping of Veta Madre open pit expansion at La Colorada
• $27M exploration program funded from operating cash flow

Heliostar Metals Ltd. (TSXV: HSTR,OTC:HSTXF) (OTCQX: HSTXF) (FSE: RGG1) (‘Heliostar’ or the ‘Company’) is pleased to provide production and cost guidance for 2026 as well as details of growth plans across the portfolio. The Company plans to produce 50,000-55,000 ounces of gold at by-product cash costs of $1,850-$1,950oz gold and a consolidated All-In Sustaining Cost (AISC) of $2,025-$2,125oz gold. Heliostar will utilize the cash generated from ongoing operations to continue to invest in exploration and growth initiatives across the Company’s portfolio, including advancement of the flagship Ana Paula development project towards production.

1. Cash costs and AISC are non-GAAP measures. Please refer to the ‘Non-GAAP Financial Measures’ section of this news release for further information on this measure.
2. AISC is based on the World Gold Council definition.
3. Mine site AISC includes only the portion of corporate G&A allocated to the operating mines. Consolidated G&A includes the aforementioned corporate G&A allocated to the operating mines plus all corporate stock-based compensation.
4. Annual average exchange rate from all costs based on Mexican peso to US dollar (18 pesos per one dollar).

The La Colorada mine (‘La Colorada’) will continue to produce metals from processing Junkyard and other stockpiles with a focus on additional re-leaching opportunities at the operation. The San Agustin mine (‘San Agustin’) successfully resumed mining operations in December 2025 (see the press release dated December 17, 2025) and will continue mining, crushing, stacking and leaching activities to produce gold and silver through 2026 and beyond.

La Colorada

In 2026, the Company expects to produce 20,000-22,300 ounces of gold at an AISC of $1,775-$1,875 per ounce of gold. This will come from crushing and stacking stockpiles, including the Junkyard Stockpile ore, a portion of the Truckshop Stockpile and re-leaching opportunities.

Development of the Veta Madre open pit expansion project is planned to commence in early Q3. The Company plans to conduct pre-stripping of 11 million tonnes of waste in 2026 to access the 43,000 ounces of in-situ gold in reserves at Veta Madre starting in the first half of 2027. This is a key growth initiative that will drive increased production at the mine in 2027.

De-risking drilling of Veta Madre and Veta Madre Plus (a planned cutback and possible expansion, respectively) is ongoing. The results of this program will provide technical information for a refined pit design and may lead to additional mineral reserves. Heliostar has also budgeted for regional exploration beyond the main mine trend at La Colorada with the aim of unlocking the full geologic potential of the larger, under-explored land package. In addition, the Company has planned for a dedicated drill program in the second half of 2026 to investigate the underground potential below the existing open pits at La Colorada. Heliostar intends to invest up to $5.8M in resource development and exploration activities at La Colorada in 2026.

San Agustin

After successfully restarting open pit production in December 2025, the operation will produce at steady state through 2026 and beyond. The Company expects the mine to produce 30,000-32,700 ounces of gold at a site-level, by-product AISC of $2,150-$2,250 per ounce of gold. The increase in cost compared to that shown in the January 2025 Feasibility Study is driven by general inflation, higher contractor mining costs and allocation of corporate general and administrative costs.

Drilling focused on expanding the oxide reserves at the Corner Area and around the existing open pit is ongoing, with 13,000 metres budgeted in 2026. In addition, Heliostar has planned up to 5,000 metres of drilling to investigate the high-grade portions of the large, polymetallic sulphide deposit that sits both adjacent to and beneath the oxides currently being mined. Further, $2.0M has been earmarked for exploration of Heliostar’s claims across the district, including early-stage exploration of the silver-rich Consejo veins mapped at surface. The Company plans to invest up to $9.7M through this year to unlock the full geologic potential of the property.

Ana Paula

The ongoing 20,000 metre infill and expansion drill program at Ana Paula will continue through Q1 2026. Given the success to date, an additional 6,500 metres have been approved to continue to upgrade inferred material currently in the Preliminary Economic Assessment mine plan. Heliostar has commenced work to complete a Feasibility Study for Ana Paula, scheduled to be completed in the first half of 2027. This important milestone will fully define the construction and operating plans to develop a 100k ounce per year gold mine.

Heliostar plans to continue to advance the existing 412 metre production-scale decline into the Ana Paula deposit in 2026. This work is planned to start in Q3 and is part of a broader de-risking and early works program to support production at the mine in the second half of 2028. The completion of the decline will also provide a platform for underground drilling to continue to expand the Ana Paula deposit at depth and explore for the causative intrusion and potential mineralized contact skarn deposit.

In addition, $1.5M has been budgeted for early-stage, regional exploration at Ana Paula. This includes a drone magnetics survey, ground-based gravity survey, property-wide soil sampling and geologic mapping. The Ana Paula project sits on a largely unexplored 56,334ha land package – one of the largest in the prolific and highly prospective Guererro Gold Belt. In total, Heliostar plans to invest $6.6M in resource development and regional exploration at Ana Paula in 2026, in addition to the $15.0M required to extend the decline.

Other Properties

At Cerro del Gallo, Heliostar is advancing permitting discussions alongside active engagement with the local communities and social benchmarking surveys. The Company’s workplan includes an update of the geologic model to allow flotation trade-off testing, further metallurgical test work of the sulphide portion of the deposit and hydrological data collection.

Unga and San Antonio will see modest exploration and metallurgical programs, respectively.

The total planned exploration, development and study expenditure for these properties is $4.9M.
