Nine Mile Metals LTD. (CSE: NINE,OTC:VMSXF) (OTC Pink: VMSXF) (FSE: KQ9) (the ‘Company’ or ‘Nine Mile’) is pleased to provide the details of drill hole WD-25-05 in addition to a summary of the 2025 drill program completed in December at the Wedge Project.

Drillhole WD-25-05:

DDH WD-25-05 collared on the same drill pad as WD-25-01 and drilled at an azimuth of 310 degrees and a dip of -60 to a final depth of 275 meters.

• DDH-WD-25-05 was successful, intersecting massive VMS (Cu, Pb, Zn, Ag, Au) mineralization between 155.52 – 157.80 meters (Figure 1) followed by 40 meters of mineralized felsic volcanics (rhyolite) as seen in Figure 2 between 157.80 and 197.80 meters before terminating in sediments.
• Mineralization consisted of both pyrite and chalcopyrite as disseminations, masses, and associated with quartz bands parallel to bedding.
• All drill core has been measured, logged, photographed, marked, and cut for sampling at the company’s warehouse in Bathurst, New Brunswick. A quick XRF analysis was also completed for sulphide confirmation – filtering and width identification in definition for sampling core for Actlabs Analysis. A total of 55 sections were delivered to ALS Global in Moncton, New Brunswick for Base and Precious Metals analysis, including Antimony.

Drill Holes BHEM -01 and BHEM-02:

Both drill holes were collared on permitted drill pads in the northwest along the western extension (Figure 4). The drill core for both BHEM-01 and BHEM-02 were solid with minimal faulting / fracturing in the host sediments providing ideal drill holes for surveying and subsequent follow up. Collared outside of known mineralization, the holes are well positioned to locate and model adjacent mineralization with no interference from a conductive source within the drill hole. Both holes are capped and easily accessible, the drill pads available for extending drilling further west and if required, additional depth.

Gary Lohman, VP Exploration, Director stated, ‘Our Wedge Drill Program has been very successful, intersecting Massive Cu bearing VMS where targeted in the western extension of the Wedge Deposit, as designed. Two holes were also drilled in the Northwest area to facilitate an upcoming BHEM survey, their locations in solid rock on the flanks of previous underground workings. In addition to identifying additional mineralization, the size and scale of the individual geological units and results from the upcoming BHEM program will assist in modeling the deposit and targeting additional drilling along the western extension. After our successful drilling in the southern lower extension of the deposit, our knowledge of the deposit and mineralization has increased and identified new areas of priority that were not permitted for this past drill program. We have identified new drill collar locations to continue to test the Copper Zone on the western extension in addition to potential locations that avoid the shear zone in the south. New permitting is underway in preparation of an exciting 2026 campaign at the Wedge, including our West Wedge and Tribag Target Trend drill programs.’

2025 Drill Program Overview:

The program consisted of 7 drill holes totaling 1,654 meters with 5 holes targeting copper mineralization in the western extension of the Wedge Mine with two additional holes collared in the northwest to facilitate BHEM (Bore Hole Electromagnetic) surveying this spring. The goal is to map the depth of the deposit and define the new copper zone. We should also be able to map the western parameters of the deposit, heading west towards the Tribag and West Wedge along trend.

The 2025 drill program was highly successful, with all five drill holes targeting copper mineralization intersecting both massive VMS (Cu, Pb, Zn, Ag, Au) and banded copper sulphide mineralization. The two holes collared to facilitate BHEM geophysical surveying were also successful, collared in the northwest portion of the western extension, away from the large, graphitic shear zone that bounds the deposit in the south and west of the interpreted extent of previous, underground workings. BHEM surveying has its best results when drilled away from the mineralization and the magnetic interference.

The five drill holes targeting mineralization were all collared in the southwest, crossing through a brecciated, graphitic shear zone (tectonic melange) before intersecting a well-defined massive VMS (Cu, Pb, Zn, Ag, Au) horizon. This is characteristic of the mineralized contact after which a sequence of intercalated sediments and volcanics are cut prior to the holes intersecting the main zone of VMS mineralization with mineralized widths between 13 and 48 meters.

The VMS mineralization consisted of abundant pyrite and lesser chalcopyrite, sphalerite, and galena. Local, secondary copper, covellite (CuS) and bornite (Cu₅FeS₄), was also identified in drill holes WD-25-02 and WD-25-04.

In the west, the metal zonation appears different than the drill holes completed in the east with the prevalence of a greater concentration of chalcopyrite and pyrite with lesser galena (Pb) and sphalerite (Zn). Although it is early in the process, we have confirmed the presence abundant chalcopyrite and coarser grained pyrite in the western extension.

The key observations in this program include:

• Graphitic Shear Zone in contact with VMS confirmed as a diagnostic marker horizon in the southwest.
• Mineralized siliceous volcanics were intersected in numerous drill holes, defining an additional, mineralized sequence.
• VMS mineralization occurs in multiple horizons as seen in holes WD-25-01 and WD-25-02.
• The intersected units (Argillite, VMS and Felsic Volcanics) are of substantial width and extent which will assist in the 3D modeling of the deposit and subsequent drill hole targeting.

Patrick J Cruickshank, MBA, CEO & Director, stated, ‘We are thrilled with the success of our Wedge Phase 2 Drill Program. To have all 5 holes strike mineralization was more than we expected. It is a testament to our Technical Team and specifically, Mike Dufresne and Gary Lohman. We already have identified Phase 3 Drill holes and are determined more than ever to expand this deposit’s footprint and expose this entire new 3^rd High Grade Copper Lens. In addition, the BHEM surveys, the Phase 3 Wedge Drilling, the TriBag & West Wedge drilling to test this VMS Cluster Trend, 2026 will be filled with Wedge Project activity. We expect our first Assays to arrive this week from ALS Global and look forward to sharing the results.’

Tartisan Nickel Corp. (CSE: TN,OTC:TTSRF) (OTCQB: TTSRF) (FSE: 8TA) (‘Tartisan’, or the ‘Company’) is pleased to announce that the Company has acquired eleven additional claims in the Turtle Pond Area, approximately 40 kms south of Dryden, Ontario and approximately 70 kms east of the Company’s flagship Kenbridge Nickel-Copper-Cobalt Project.

The total property package now consists of 161 claims covering 3,375 ha. The claims are owned 100% by Tartisan Nickel Corps. wholly owned subsidiary Canadian Arrow Mines Limited. The property is situated in an area with excellent infrastructure.

Previous exploration efforts identified nickel-copper sulphide mineralization in twelve trenches along a 700-metre trend at the Glatz nickel copper showing. The zone, discovered in 1965 by local prospector A. Glatz, is up to 40 metres wide and is open along strike and at depth. Historical grab samples were reported to contain up to 1.95% Ni. In 2007, Canadian Arrow Mines Limited conducted a surface grab sampling program which produced the following results: 1.28% Ni, 0.26% Cu re Glatz Trench 3; 0.99% Ni, 0.18% Cu re Glatz Trench 3; 0.39% Ni, 4.06% Cu re Trench 4. The mineralization varies from disseminated sulphides to narrow semi-massive sulphide bands. Six short drill holes were completed at that time with hole GZ-09- 02 encountering 0.34% Ni, 0.16% Cu and 0.02% Co over 5.9 m from 45.0-50.9 m.

A nickel-copper-PGE discovery on the Double E airborne VTEM anomaly was identified in 2008. The drilling intersected two separate upper and lower mineralized zones in 2 drill holes. Hole EE-09-02 intersected 4.2 metres of 0.81% Ni, 0.52% Cu, 0.20gpt Pt, 0.16gpt P and 0.20gpt Au at a depth of 25.5 metres. This included 2 metres of 1.35% Ni, 0.81% Cu, 0.36gpt Pt, 0.27gpt Pd and 0.31gpt Au. A second zone was intersected at a depth of 135.1 metres containing 8.2m of 0.55% Ni and 0.38% Cu. Hole EE-l0-04 intersected 1.9 metres of 0.51% Ni, 0.24% Cu at a depth of 21.4 metres and a second narrow intersection of 1.9 metres of 0.52% Ni, 0.28% Cu at a depth of 28 metres.

Exploration diamond drilling work completed in 2009 and 2010 on the Night Danger nickel-copper reported a nine-metre-wide section of stringers and blebs of sulphide which assayed 0.57% Ni and 0.45% Cu at a drill depth of 79m in hole ND-09-1. Two sections within this interval assayed greater than 1% nickel. Drill hole ND-10-1 intersected 4.53% Ni over 0.7m at a drill depth of 57.5m (Source; MNDM assessment files and Canadian Arrow Mines Limited news release dated June 1, 2010, SEDAR).

From November 28^th to December 21^st, 2024, a TDEM Geophysical survey was performed on the Turtle Pond Property undertaken by Expert Geophysics Limited (SEDAR+ February 27, 2025). Tartisan Nickel Corp. conducted this survey for the purpose of determining drill targets and potential future exploration work on the Turtle Pond Project.

Mark Appleby, President and CEO of Tartisan stated ‘The Glatz, Double E and Night Danger nickel-copper showings display similar nickel and copper tenors as what we find near surface at our Kenbridge Nickel-Copper-Cobalt Project. Acquisition of these claims complement the company’s larger objective of developing the Kenbridge Nickel-Copper-Cobalt Project into an operating mine with a central milling facility. The Company will be formulating an exploration program consisting of surface sampling and potentially diamond drilling for 2026-27.

Sankamap Metals Inc. (CSE: SCU) (‘Sankamap’ or the ‘Company’) is pleased to announce assay results from its Oceania Project on the Fauro Property. The preliminary exploration program on Fauro’s 24,000-hectare (‘Ha’) property located in the Shortland Islands, Western Province, Solomon Islands, included grab samples during a November 2025 site visit. These samples returned multiple high-grade gold (Au) and silver (Ag) results at the Meriguna Target, including up to 116 grams per tonne (gt) Au and 87.5 gt Ag.

CEO, John Florek, commented:

‘Once again, our work at the Fauro Property has delivered very high-grade results. At Meriguna, about 2.5 kilometres north of the Kiovakse target, which previously returned exceptional gold and copper values (see press release dated July 16, 2025), we continue to see compelling evidence of a robust mineralized system.

The scale of mineralization and the strength of the grades encountered across the property underscore its significant discovery potential. Importantly, multiple analogous geophysical signatures along the rim of the caldera remain untested, providing substantial upside as we advance our exploration program.’

Highlights

• Meriguna returned several high-grade gold values, of up to 116 g/t Au, and an average grade of 16.4 g/t Au across all rock samples.

• Silver values show a strong correlation with gold, returning assays of up to 87.5 g/t Ag.

• Visible gold was identified throughout the property in surface alluvial workings from local artisanal miners at the Meriguna Prospect.

• Meriguna and the Kiovakse target demonstrate strongly comparable alteration and mineralized signatures highlighting the potential scale and continuity of mineralization across the area.

• The team is advancing and refining mineralized zones to generate high-priority drill target.

• A phased 2026 exploration program will continue systematic sampling to validate historical results, followed by targeted geophysical surveys. All data will be integrated to design a focused drill program aimed at confirming historical intersections and testing extensions of mineralization that remain open at depth and along strike.

Discussion of Results

The Meriguna target at the Fauro Property continues to deliver highly encouraging results and is located approximately 2.5 km from the Kiovakse target, highlighting the broader prospectivity of the area. The November 2025 site visit successfully validated historical data while generating new geological vectors to refine and prioritize future drill planning. As summarized in the accompanying table (see Table 1), surface sampling returned multiple high-grade gold results, including exceptional assays of up to 116 g/t Au, underscoring the presence of a robust mineralizing system at Meriguna.

These high-grade gold values, together with consistently elevated gold, silver, and copper results from both the Meriguna and nearby Kiovakse targets, underscore the effectiveness of the Company’s focused and systematic exploration strategy. Collectively, the results support the presence of a strong epithermal system and continue to advance multiple high-priority targets across the Fauro Property.

Oreterra Metals Corp. (TSXV: OTMC) (OTCID: RMIOD) (FSE: D4R0) (WKN: A421RQ) (‘Oreterra’ or the ‘Company’) (previously, Romios Gold Resources Inc.) is pleased to announce that it intends to complete a non-brokered private placement financing for aggregate gross proceeds of up to $6,000,000 through the issuance of a combination of hard-dollar units (‘HD Units’) of the Company at a price of $0.45 per HD Unit and flow-through units (‘FT Units’) at a price of $0.50 per FT Unit (collectively, the ‘Offering’). Closing of the Offering is scheduled for March 20, 2026. The majority of the gross proceeds from the sale of both the HD Units and the FT Units will be used to carry out the first-ever drilling in the approaching field season of the large-scale Trek South porphyry copper-gold prospect located in northwestern B.C. The Trek South prospect is new to science, having been revealed by ice melt in recent years, and consists of stacked, high-order alteration, geochemical and geophysical anomalies. It is located in BC’s Golden Triangle, adjacent to Teck-Newmont’s Galore Creek deposits in ideal terrain, and close to partially completed infrastructure. A comprehensive NI 43-101 technical report on the Trek property dated January 20, 2026, can be found at www.oreterra.com and on the Company’s issuer profile at www.sedarplus.ca. An investor presentation summarizing the Trek South prospect can also be found at www.oreterra.com.

In connection with the Offering, the Company has entered into a fiscal advisory agreement with Canaccord Genuity Corp. (‘Canaccord‘). Subject to the approval of the TSX Venture Exchange (‘TSXV‘), the Company shall compensate Canaccord in the amount of $25,000, payable in HD Units of the Company (the ‘Compensation Units‘) to be issued at C$0.45 per Compensation Unit with the same terms as HD Units. In addition, 6% finder’s fees in cash or securities, or a combination of both, may be payable by Oreterra in connection with the Offering, subject to the rules of the TSXV.

Insiders may participate for up to 10% of the Offering. Such insider private placements will be exempt from the valuation and minority shareholder approval requirements of Multilateral Instrument 61-101 (‘MI 61-101‘) by virtue of the exemptions contained in sections 5.5(a) and 5.7(1) (a) of MI 61-101 in that the fair market value of the consideration for the securities of the Company which will be issued to the insiders will not exceed 25% of its market capitalization.

About Oreterra Metals Corp.

Oreterra Metals Corp. commenced trading on February 2, 2026, under the new ticker OTMC, following a months-long effort to restructure the former Romios Gold Resources Inc. Management took on the task because it believes the Company’s wholly-owned Trek South porphyry copper-gold prospect represents, based upon the impressive results of the spectrum of geosciences applied to the target area to date, among the finest new targets of its kind in BC’s Golden Triangle. The Company recently released (news, January 22, 2026) a National Instrument 43-101 Technical Report for the Trek property which recommends two initial phases of drilling at Trek South, for execution in the approaching 2026 field season. A copy of the Technical Report is available on the Company’s website at www.oreterra.com, and on the Company’s SEDAR+ issuer profile at www.sedarplus.ca.

Additional wholly-owned Company property interests include two former producers in Nevada: the Kinkaid claims in the Walker Lane trend covering numerous shallow Au-Ag-Cu workings over what is believed to be one or more porphyry centres (source: J. Biczok, P.Geo, June 2025, Kinkaid Gold-Copper-Silver Project, www.oreterra.com), and the Scossa mine property in the Sleeper trend which is a former high-grade gold producer (source: J. Biczok, P.Geo, July 2025, Scossa Historic Gold Mine Property, www.oreterra.com). The Company also holds a 100% interest in the large Lundmark-Akow Lake Au-Cu property adjacent to the northwest of the Musselwhite Mine in northwestern Ontario, where drilling by the Company has produced highly encouraging, broad VMS-style Au-Cu intersections.

Neither the TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.

Cardiol Therapeutics Inc. (NASDAQ: CRDL) (TSX: CRDL) (‘Cardiol’ or the ‘Company’), a late-stage life sciences company focused on advancing the development of anti-inflammatory and anti-fibrotic therapies for heart disease, today announced the publication of results from its Phase II ARCHER study in ESC Heart Failure, a journal of the European Society of Cardiology.

The peer-reviewed article reports results from a randomized, double-blind, placebo-controlled trial evaluating CardiolRx, Cardiol’s lead oral drug candidate, in 109 patients with acute myocarditis using advanced cardiac magnetic resonance (CMR) imaging measures of myocardial inflammation and remodelling.

In the study, treatment with CardiolRx produced a significant reduction in left ventricular mass versus placebo (-9.2 g; p=0.0117), along with a decrease in left atrial remodelling, and favorable trends across multiple markers of myocardial inflammation. CardiolRx was also shown to be safe and well tolerated. Reduction in left ventricular mass is widely considered consistent with decreased myocardial edema and inflammatory burden in myocarditis and improved clinical outcomes.

The biological signals observed in ARCHER are directly relevant to Cardiol’s ongoing pivotal Phase III MAVERIC trial in recurrent pericarditis. Myocarditis and pericarditis are inflammatory diseases of the myocardium and pericardium, respectively, and are recognized to fall within the spectrum of inflammatory myopericardial syndrome, an umbrella term describing the potential myocarditis-pericarditis overlap: similar causes, anatomical contiguous structures, and mixed forms with possible reciprocal involvement, such as myopericarditis and perimyocarditis.

‘This publication marks an important moment in the broader dissemination of CardiolRx’s therapeutic potential,’ said David Elsley, President and Chief Executive Officer of Cardiol Therapeutics. ‘ARCHER provides additional compelling clinical evidence that CardiolRx impacts the underlying biology of inflammatory heart disease and reduces inflammation-driven structural damage in the heart, increasing our confidence in MAVERIC, which is focused on delivering meaningful outcomes for patients with recurrent pericarditis.’

About Cardiol Therapeutics

Cardiol Therapeutics Inc. (NASDAQ: CRDL) (TSX: CRDL) is a late-stage life sciences company focused on advancing the development of anti-inflammatory and anti-fibrotic therapies for heart disease. The Company’s lead small-molecule drug candidate, CardiolRx, modulates inflammasome pathway activation, an intracellular process known to play an important role in the development and progression of inflammation and fibrosis associated with pericarditis, myocarditis, and heart failure.

The MAVERIC Program is evaluating CardiolRx for the treatment of recurrent pericarditis, an inflammatory disease of the pericardium associated with symptoms including debilitating chest pain, shortness of breath, and fatigue, which can lead to physical limitations, reduced quality of life, emergency department visits, and hospitalizations. The program comprises the completed Phase II MAvERIC-Pilot study (NCT05494788) and the ongoing pivotal Phase III MAVERIC trial (NCT06708299). The U.S. FDA has granted Orphan Drug Designation to CardiolRx for the treatment of pericarditis, including recurrent pericarditis.

The ARCHER Program is also studying CardiolRx, specifically in acute myocarditis-an important cause of acute and fulminant heart failure in young adults and a leading cause of sudden cardiac death in individuals under 35 years of age. The program comprises the completed Phase II ARCHER study (NCT05180240), which evaluated the safety, tolerability, and efficacy of CardiolRx in this patient population.

The Company is also developing CRD-38, a novel, subcutaneously administered drug formulation intended for the treatment of inflammatory heart disease, including heart failure-a leading cause of death and hospitalization in the developed world, with associated healthcare costs in the United States exceeding US$30 billion per year.
