Highlights:

• Strategic Agreement represents combined total project consideration of up to CAD $61.5 million consisting of cash or share payments to Skyharbour totalling up to $21.5 million (including $18.0 million before year end) plus expenditures totalling up to $40.0 million for Denison to acquire between a 20% and 70% ownership interest over seven years in the claims making up Russell, with Skyharbour owning the remaining interests.

• Denison (TSX: DML; NYSE American: DNN), a leading uranium mining company with a market capitalization of over $3 billion, is developing the Wheeler River Project (‘Wheeler River’), which shares a 55 kilometre border with Russell. Denison is an existing, large corporate shareholder of Skyharbour and now joins the Company as a strategic, active, funding partner at Russell.

• The Project will be divided into four different joint ventures, including Russell Lake (‘RL’), Getty East, Wheeler North, and the Wheeler River Inlier Claims, of which Skyharbour will retain initial ownership interests of 80%, 70%, 51%, and 30%, respectively. Denison can then earn up to a 70% interest in the Wheeler North and Getty East properties through option agreements.

• The technical teams of Denison and Skyharbour will work cooperatively to advance and unlock value across the joint ventures, employing top-tier exploration and development expertise in the region.

• Denison has committed to a minimum of $4 million in exploration expenditures over the first two years at Wheeler North and Getty East combined, as well as agreeing to fund to maintain its pro-rata 20% participation interest in the RL claims through 2029 up until such time that total exploration expenditures on the property reach $10 million.

• Skyharbour to remain operator with an 80% ownership interest at the RL claims comprising over 53,192 hectares of the original 73,314 hectare Russell Lake Project. The Company will also act as operator during the first earn-in at Getty East with Denison sole funding the exploration in order to fulfill the earn-in option criteria.

• Skyharbour to benefit with a substantial financial commitment from Denison before year end to help fund its uranium exploration and corporate activities through 2026. The Company will also generate revenue from its operator fee at the McGowan Lake exploration camp at the Project.

• Skyharbour will continue to directly advance its high-grade Moore Uranium project as well as the RL claims at Russell, while partner companies fund exploration at some of the Company’s other projects.

Jordan Trimble, President and CEO of Skyharbour, stated: ‘This is a transformative transaction for Skyharbour and our shareholders as it represents a major stamp of approval for Russell with up to $61.5 million in combined project consideration coming in. We are very pleased to expand upon our long-standing relationship with Denison and to partner with their team to advance one of the more prospective exploration projects in the Athabasca Basin proximal to existing and developing mines. Denison’s success in exploring, permitting, and developing the neighboring world-class Wheeler River Project will provide considerable insight and experience as we jointly pursue success at Russell. Further, this transaction delivers on our belief that Russell should be treated as multiple different projects due to the abundance of targets and sheer scale of the land package in one of the most prolific uranium exploration corridors in the world. The structure and terms of the Strategic Agreement allow Skyharbour to continue exploring as operator at the majority of the claims at Russell, while participating in the future success that Denison seeks as operator at the Wheeler North and Wheeler River Inlier claims. Furthermore, we will receive a significant amount of cash and Denison shares to help fund our exploration efforts and corporate activities through 2026.’

David Cates, President and CEO of Denison, further commented: ‘As Denison nears receipt of final regulatory approvals for the Phoenix In-Situ Recovery mine proposed for our flagship Wheeler River property, we are also making measured investments in our project pipeline – including our next development assets and high-potential exploration properties. Given its proximity to Wheeler River, Denison has had an interest in adding Russell to our property portfolio for much of my nearly two decades with the Company. This transaction achieves that objective by providing Denison with the opportunity to lead and participate in exploration efforts across four newly created joint ventures, which are designed to drive collaboration between Denison and Skyharbour’s technical teams. We are excited to build on our long-standing relationship with Skyharbour and accelerate the evaluation of this exceptional package of highly prospective ground.’

Upon closing of the Strategic Agreement, Denison will earn an initial project interest in each of the four new Russell exploration projects including a 49% interest in the Wheeler North claims, a 20% interest in the RL claims, a 30% interest in the Getty East claims, and a 70% interest in the Wheeler River Inlier claims.

1. Wheeler North (51% SYH, 49% DML ; subject to additional earn-in options ) : The yellow claims in the map above represent 16,409 hectares over eight claims. The claims host some of the exploration targets located proximal to Wheeler River, including the Grayling and Fork Zones. Upon closing of the Transaction, Denison will have the option to increase its interest in Wheeler North to a 70% interest in these claims and Denison will become the operator of Wheeler North as described in more detail below.
2. Russell Lake or RL (80% SYH, 20% DML) : The pink claims in the map above represent 53,192 hectares over 16 claims. These claims are located north and west of Skyharbour’s Moore Project and host numerous exploration target areas including Christie Lake, NE Russell, Blue Steel, Taylor Bay, South Russell, and Kowalchuk Lake. In order to maintain its initial interest in RL, Denison has agreed to fund its pro rata share of up to a maximum of C$10.0 million in total project expenditures. Upon the closing of the Transaction, Skyharbour will remain operator of RL.
3. Wheeler River Inliers (30% SYH, 70% DML) . The blue claims in the map above represent 608 hectares over two claims. These are inlier claims within Denison’s Wheeler River project hosting the West Russell and C-Block exploration target areas. DML will become operator of the Wheeler River Inliers.
4. Getty East (70% SYH, 30% DML ; subject to additional earn-in options ) . The green claim in the map above representing 3,105 hectares is host to the Little Man Lake exploration prospect. The claim borders Cameco’s Cree Zimmer property which holds its Key Lake operations to the south.  Upon the closing of the Transaction, Skyharbour will remain operator of Getty East; however, Denison will have the option to become the operator and acquire up to a 70% interest in this joint venture as described in more detail below.

Transaction Details:

The consideration payment will consist of a $2 million cash payment immediately upon execution of the Strategic Agreement (the ‘Upfront Payment’), and deferred consideration of $16 million (the ‘Deferred Consideration’) payable on or before December 31 ^st , 2025.

The Deferred Consideration shall be payable in two tranches, each of which may be paid in cash or shares of Denison at Denison’s election, including $8 million on or before the fifth business day prior to December 21 ^st , 2025, and another $8 million within 10 days of December 21 ^st , 2025. Closing of the transaction (‘Closing’) is expected to occur on or before December 21 ^st , 2025.

The current exploration camp at McGowan Lake on the Project will continue to be operated by Skyharbour and an administrative fee will be payable by Denison to Skyharbour. The claims comprising Russell are subject to various existing underlying royalties to other parties.

The Transaction is subject to customary approvals, including Skyharbour obtaining TSX Venture Exchange approval. The Transaction will be considered a Reviewable Transaction under TSX Venture Exchange policies as David Cates is a director of both Denison and Skyharbour.

Russell Lake Uranium Project Overview:

The Russell Lake Project is a large, advanced-stage uranium exploration property totalling 73,314 hectares strategically located between Cameco’s Key Lake and McArthur River Projects, and adjoining Denison’s Wheeler River Project to the west and Skyharbour’s Moore Uranium Project to the east. The northern extension of Highway 914 between Key Lake and McArthur River runs through the western extent of the property and greatly enhances accessibility, while a high-voltage powerline is situated alongside this road.

Skyharbour’s New 80% Owned RL Project:

The claims making up the RL Project constitute over seventy percent of the original Russell project area and will continue to be explored by Skyharbour as the operator and 80% owner. Denison will acquire a 20% interest and has agreed to fund to maintain its pro-rata participation interest in the RL claims through December 31 ^st , 2029, or until such time that total expenditures on the properties have reached $10 million.

The RL claims have numerous highly prospective targets that Skyharbour will continue to advance. The Christie Lake target area contains basement-hosted uranium mineralization with historical drilling returning 0.17% U ₃ O ₈ over 0.4 metres at 436.4 metres depth in hole CL-10-03, hosted within a strongly hematized breccia. A prospective clay altered basement fault system runs throughout this area.

The Blue Steel target area comprises graphitic metasediments that were last drilled in 2008. The full extent of the graphitic corridor remains unknown and completely untested. Historical geophysics indicate potential faulting along this corridor, highlighting it as a priority area for follow-up work using modern geophysical methods to refine drill targets.

The Kowalchuk area, situated within the southern Russell claims, is another prospective area on the RL claims, with multiple inferred structural trends passing through it. This area has seen only limited modern geophysical coverage to date.

In addition to the aforementioned target areas, there are many kilometres of untested EM conductors on the RL claims underlain by rocks of low magnetic intensity, suggestive of the presence of prospective graphitic meta-pelitic basement lithologies typical of Athabasca-style uranium systems. With limited modern exploration conducted over the past 12 years, the RL claims remain underexplored and highly prospective for both expanding known mineralized zones and making new discoveries.

Brunswick Exploration Inc. (TSX-V: BRW, OTCQB: BRWXF; ‘ BRW ‘ or the ‘ Company ‘) is pleased to announce inaugural drilling results from its Anatacau Main Project, located in the Eeyou Istchee-James Bay region of Quebec. All drillholes were centered on the Anais showing and intercepted multiple, large spodumene-bearing pegmatites with rich lithium mineralization. The pegmatites are found along a major deformation corridor, reminiscent of the neighboring Galaxy deposit owned by Rio Tinto located 22 kilometers to the West.

Highlights include:

• 1.66% Li2O over 47.2 meters in drill hole AN-25-05 within a larger package of continuous lithium mineralization (present within both country rock and pegmatites) of 120.7 meters at 1.31% Li2O .
• Very high cesium values intercepted in multiple secondary sub-parallel dykes including 1.46% Cs2O over 1 meter and 0.8% Cs2O over 1 meter.
• This latest discovery is now drill traced over 170 meters of strike length and is open in all directions.

Mr. Killian Charles, President and CEO of BRW, commented: ‘Today’s exciting results underscores the opportunities across our continuously growing portfolio. We are rapidly starting to define a sizeable lithium system at Anatacau Main which, importantly, remains open in all directions. Furthermore, we are seeing mineralization constrained to the same structural corridor that is found at Rio Tinto’s Galaxy project (54.3Mt M&I at 1.30% Li2O and 55.9Mt Inferred at 1.29%, see Note ) and BRW’s Anatacau West. At Anatacau Main, we control over 18 kilometers of this highly prospective corridor which will be the focus of subsequent work in Q1 2026.

Between these strong results at Anatacau, a forthcoming maiden resource estimate for Mirage, an inaugural drill campaign in Greenland and further growth opportunities beyond the existing portfolio, Brunswick Exploration is among the most exciting companies in the lithium exploration space.’

Results Interpretation

The largest pegmatite outcrop observed at the Anais showing has now been extended to over 170 meters in strike length and to a maximum depth of 98 meters. It remains open in all direction with an apparent thickness of 47.2 meters (DDH AN-25-05) at its widest point. The main pegmatite dyke is interpreted to be dipping 85 degrees to the West. Several other, well-mineralized stacked pegmatite intervals were also intercepted in all holes, demonstrating the potential for more dyke discoveries in the vicinity of the outcrop (Figure 1). The mineralized dykes discovered at Anatacau straddle the southern side of an interpreted major deformation zone, striking northwest-southeast; a structural control that is reminiscent of the Galaxy deposit (Figure 2). The different pegmatite dykes appear to be oriented North-South to Northeast-Southwest.

The pegmatite dykes show excellent continuity in terms and mineralogy and grade, with several high-grade zones intersected to date (Table 1, Figure 3). The mineralized pegmatite dykes typically exhibit massive to coarse crystals (15+centimeters) with a mineralogy consisting of quartz, white K-feldspar, plagioclase, white spodumene, and minor amounts of muscovite, fine-grained tourmaline, and blue apatite. Spodumene crystals are inclusion-free and are consistently white unlike spodumene mineralization found at the Galaxy deposit and Anatacau West which varies from off-white to greenish. Some pegmatite intervals are under the cut-off of 0.3% Li2O but demonstrate high values of tantalum and cesium (up to 1.46% Cs2O in a 1 meter interval). This highlights the potential for other types of mineralization and by-products at the Anatacau Main project, a feature uncommon in other James Bay projects.

Host rocks consist of greywacke and amphibolite, locally deformed into schist near the deformation zone where pegmatites seem to propagate well into both units. Holmquistite, a lithium amphibole, is commonly observed in all host rocks at varying concentrations (up to 1.5% Li2O in host rock) over significant widths. This pervasive lithium alteration is potentially indicative of significant lithium bearing fluids along the deformation corridor and could be potentially used as a vectoring tool for further discoveries.

A geometallurgical study is underway at SGS using DMS (Dense Media Separation) with results expected early in 2026.

Anatacau Drilling Campaign Overview

Six (6) diamond drill holes were completed (see Figure 1 and Table 2) for a total of 750 meters. The holes were spaced by 55 to 100m, and all holes intercepted mineralized pegmatites.

The aim of the 2025 drilling campaign was to test at shallow depths (less than 150 meters vertical depth) the pegmatite dykes mapped at surface on the Anaïs showing. The drilling campaign was performed in HQ size to perform a geometallurgical study, planned according to a grant from the Ministry of Natural Resources and Forests of the Quebec Government.

Brunswick Exploration discovered the Anais showing in 2023, which consists of several parallel pegmatite dykes with visible spodumene mineralization. The largest dyke found to date is exposed over a 15 m wide by 100m long outcrop. Several grab samples returned high grade values ranging from1.19 to 3.83% Li2O on the outcrop itself (see press release dated July 13, 2023). The Anais lithium discovery is located 22 kilometers East and along strike from Rio Tinto’s Galaxy project and BRW’s Anatacau West project.

QAQC

All drill core samples were collected under the supervision of BRW employees and contractors. The drill core was transported by helicopter to the logging facility at camp Wabamisk. and by truck from the drill platform to the core logging Each core was then logged, photographed, tagged, and then packed to be shipped to Val-d’Or. Core splitting by diamond saw and sampling was done by BRW contractor at their Val-d’Or facility. All pegmatite intervals were sampled at approximately 1m intervals to ensure representativity, excluding all host rock material. Host rock was also sent for analysis 1m before and after each pegmatite interval. Samples were bagged, and blanks, pulp duplicates and certified reference materials for lithium were inserted at regular intervals. Groups of samples were placed in larger bags, sealed with numbered tags, in order to maintain a chain of custody. The sample bags were transported from BRW contractor facility to the Agat laboratory in Val-d’Or. All sample preparation and analytical work was performed by Agat Laboratories. Samples were crushed in order for 75% of the material to pass through a 2mm screen (method 200075), split to a sub-sample of 250g, and the split sample pulverized (200087) to obtain more than 85% of the material passing a 75µm screen. A sub-sample of the pulverized fraction was dissolved in a sodium peroxide solution, prior to lithium analysis by ICP-OES and ICP-MS according to the Agat method 201378. All results passed the QA/QC screening at the laboratory, and all inserted standard, duplicates and blanks returned results that were within acceptable limits. All reported drill intersections are calculated on the basis of a lower cutoff grade of 0.30% Li2O.

Gold: Global Demand & Supply

Global demand for gold remains strong, supported by persistent geopolitical uncertainty, inflationary pressures, and ongoing central bank purchases. At the same time, supply growth is limited, with declining reserves at mature mines, few large-scale discoveries, and rising development costs. This tightening supply backdrop highlights the strategic value of advancing new gold projects in secure, mining-friendly jurisdictions. Copper Quest is aligned with these global trends, positioning Alpine to contribute to the next generation of significant gold discoveries.

Stock Options

The Company has granted stock options to Directors, Management, and Consultants of the Company to acquire an aggregate of 2,600,000 common shares in the capital of the Company, pursuant to the Company’s Equity Incentive Plan. The stock options are each convertible into a common share of the Company at an exercise price of $0. 20 until November 13, 2030.

NOT FOR DISTRIBUTION TO UNITED STATES NEWS WIRE SERVICES
OR FOR DISSEMINATION IN THE UNITED STATES

Vancouver, British Columbia TheNewswire – November 13th, 2025 Prismo Metals Inc. (‘ Prismo ‘ or the ‘ Company ‘) (CSE: PRIZ,OTC:PMOMF) (OTCQB: PMOMF) is pleased to announce that further to its news release dated October 20, 2025 (the ‘ Initial News Release ‘), the Company has upsized and closed its previously announced non-brokered private placement of units of the Company (‘ Units ‘) at an issue price of $0.10 per Unit (the ‘Private Placement’ ). Due to strong investor demand, the Private Placement was increased from 12,500,000 Units to the issuance of 17,450,000 Units for gross proceeds of $1,745,000.

The Company also announced it has amended the terms of the warrants forming part of the Units (the ‘ Amendmen t’). As announced in the Initial News Release, each Unit was to consist of one common share of the Company (a ‘ Share ‘) and one-half of one common share purchase warrant of the Company (each whole warrant, a ‘ Warrant ‘). Each Warrant was to entitle the holder to purchase one Share for a period of thirty-six (36) months from the date of issuance at an exercise price of $0.175, subject to an acceleration expiry clause (the ‘ Acceleration Clause ‘), whereby if the Shares closed at or above $0.25 for ten (10) consecutive trading days on the Canadian Securities Exchange, the Company would have the right to accelerate the expiry date of the Warrants by issuing a news release announcing the accelerated Warrant term, pursuant to which the Warrants would expire on the 30 th calendar day after the date of such news release. As a result of the Amendment, each issued Unit now consists of one Share and one full Warrant, with each Warrant entitling the holder to purchase one Share for a period of thirty-six (36) months from the date of issuance at an exercise price of $0.175, without the Acceleration Clause.

The Company intends to use the net proceeds from the Private Placement primarily for drilling at its Silver King project and for general corporate purposes. There may be circumstances, however, where, for sound business reasons, a reallocation of funds may be necessary. The Company expects to accept additional subscriptions of Units in the coming days for an approximate amount of $125,000.

In connection with the closing of the Private Placement, the Company issued an aggregate of 919,960 finder’s warrants (the ‘Finder’s Warrants’ ) and paid finder’s commissions of $ 92,398 to certain qualified finders. Each Finder’s Warrant is exercisable for a period of twenty-four (24) months from the date of issuance to purchase one Share at a price of $0.10. In addition, the Company paid a cash fee of $15,000 to a financial advisor.

All securities issued or issuable in connection with the Private Placement are subject to a four-month hold period from the closing date under applicable Canadian securities laws, in addition to such other restrictions as may apply under applicable securities laws of jurisdictions outside Canada.

Multilateral Instrument 61-101

The Company has issued an aggregate of 303,275 Units pursuant to the Private Placement to certain ‘related parties’ of the Company (the ‘ Interested Parties ‘), in each case constituting, to that extent, a ‘related party transaction’ as defined under Multilateral Instrument 61-101 – Protection of Minority Securityholders in Special Transactions (‘ MI 61-101 ‘). The Company is exempt from the requirements to obtain a formal valuation and minority shareholder approval in connection with the participation of the Interested Parties in the Private Placement in reliance on sections 5.5(a) and 5.7(1)(a) of MI 61-101, as neither the fair market value of the Private Placement nor the securities issued in connection therewith, in so far as the Private Placement involves the Interested Parties, exceeds 25% of the Company’s market capitalization. The Company did not file a material change report more than 21 days before the expected closing of the Private Placement as the details of the Private Placement and the participation therein by the Interested Parties therein were not settled until recently and the Company wishes to close on an expedited basis for sound business reasons.

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

Discussion

Drill hole 30-1115, located on the eastern margin of the 2024 MRE model, did not intersect significant mineralization to a depth of 499 metres, but cut relatively high grades of 33.0 metres averaging 1.28 % Cu, 8.89 g/t Ag within the C Zone skarn horizon (expansion), as well as 56.1 metres averaging 0.59 % Cu and 3.52 g/t Ag, above the E Zone skarn horizon. The hole ended in an E zone stope where massive sulfides and high-grade skarns were previously mined.

Drill hole 30-1117, located on the western flank of Copper Mountain, cut three mineralized intervals including 779.0 metres averaging 0.26 % Cu, 1.68 g/t Ag and 0.019% Mo (which includes 312.5 metres of depth expansion), extending mineralization in this area to a vertical depth of 991 metres.

Drill hole 30-1118, located near the southern lip of the Copper Mountain open pit, cut two mineralized intervals including 555.9 metres averaging 0.20 % Cu, 1.00 g/t Ag and 0.008% Mo (infill) as well as a deeper intersection of 151.5 metres averaging 0.11 % Cu, 0.77 g/t Ag and 0.027% Mo (expansion), extending mineralization in this area to a vertical depth of 776 metres.

Drill hole 30-1123, located on the southern flank of Copper Mountain, cut three mineralized intersections, 14 to 36 metres thick and distributed in ‘layer cake’ fashion from surface to a vertical depth of 137 metres, followed by 313.5 metres averaging 0.23 % Cu, 1.84 g/t Ag and 0.012% Mo (infill and expansion) and then by 220.5 metres averaging 0.20 % Cu, 1.63 g/t Ag and 0.024% Mo (expansion), extending mineralization in this area to a vertical depth of 774 metres.

Drill hole 30-1125, located approximately 200 metres south of 30-1118, near Copper Brook, cut five mineralized intersections, 30 to 293 metres thick and distributed in ‘layer cake’ fashion from surface to a vertical depth of 936 metres, including 184.2 metres averaging 0.20 % C and 0.97 g/t Ag (infill) as well as 293.0 metres averaging 0.23 % Cu, 1.26 g/t Ag and 0.019% Mo (expansion).

Drill hole 30-1126, located on the western flank of Copper Mountain, cut two mineralized intervals including 804.0 metres averaging 0.24 % Cu, 1.48 g/t Ag and 0.016% Mo (which includes 399.4 metres of depth expansion), extending mineralization in this area to a vertical depth of 1033 metres.

Drill hole 30-1127, located near the eastern margin of the 2024 MRE model, cut eight intersections of mineralization, 17 to 45 metres thick and distributed in ‘layer cake’ fashion from surface to a vertical depth of 891 metres, confirming the near limit of the 2024 MRE model at this location.

Drill hole 30-1128, located 100 metres south of the southern margin of the 2024 MRE model, cut four mineralized intersections, all expansion outside the current resource model, including 115.5 metres averaging 0.44 % Cu and 3.67 g/t Ag within (and above) the B Zone skarn horizon, as well as 330.6 metres averaging 0.46 % Cu and 4.33 g/t Ag from the top of the C Zone skarn to well below (120 metres) the E zone horizon. This latter intersection included a high-grade interval of 14.5 metres averaging 2.51 % Cu and 24.9 g/t Ag, located in a mineralized vein/massive sulfide zone about 20 metres above the E Zone horizon. This is a new mineralized zone not previously identified at Gaspé Copper and its extent is presently unknown.

Drill hole 30-1130, located on top of Copper Mountain near the center of the 2024 MRE model, cut two significant mineralized intervals including 347.7 metres averaging 0.24 % Cu, 2.14 g/t Ag and 0.010% Mo, followed by 277.5 metres averaging 0.26% Cu, 1.51 g/t Ag and 0.023% Mo, extending mineralization in this area to a vertical depth of 874 metres.

Drill hole 30-1131, located near the southern lip of the Copper Mountain open pit adjacent to 30-1118, was drilled at a 78-degree dip towards the north and it intersected 741 metres of continuous mineralization from surface, averaging 0.21 % Cu, 1.11 g/t Ag and 0.015% Mo (infill). This hole confirmed mineralization in this area to a vertical depth of 725 metres, ending in the porphyry intrusion core of the Copper Mountain deposit.

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, that 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 which 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.
