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.

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.

Sranan Gold Corp. (CSE: SRAN) (OTCQB: SRANF) (FSE: P84) (Tradegate: P84) (‘Sranan’ or the ‘Company’) is pleased to announce that it has entered into an option agreement (the ‘Agreement’) with Lawantino N.V. (the ‘Vendor’) to acquire up to a 100% interest in the 18,468-hectare Lawantino Gold Property (the ‘Property’) situated in southeastern Suriname. The acquisition of the Property, which is currently the focus of extensive artisanal alluvial mining (see Figure 1), strengthens Sranan’s position within the highly prospective Guiana Shield, a region recognized for structurally controlled gold mineralization. The Company now controls 47,500 hectares of high-potential land for exploration.

The Property is strategically located along the same deep-seated regional structure, the Central Guiana Shear Zone (CGSZ), that hosts Founders Metals’ Antino Gold Project and Miata Metals’ Sela Creek Project, two of the most active gold exploration projects in Suriname.

The Company has confirmed the presence of extensive active artisanal alluvial mining (see Figure 2) with multiple generations of mining (miners return to the same sites with more effective equipment). Sampling of limited saprolite exposure encountered shear-hosted quartz veins cutting granite near the contact with basaltic rocks. Two samples returned 4.24 and 1.88 grams per tonne gold, which are considered significant given the limited evaluation completed.

Oscar Louzada, Sranan’s CEO, stated: ‘The Lawantino acquisition is a strategic addition to our Suriname exploration portfolio, strengthening our position along a proven and highly prospective structural corridor. The Project benefits from favourable geology, clear evidence of gold endowment through ongoing artisanal mining, and proximity to two active gold exploration projects. Lawantino fits well with our disciplined growth strategy and complements our ongoing work at Tapanahony as we continue to build value through systematic exploration.’

Sranan’s initial exploration program will focus on integrating areas of artisanal mining with satellite interpretation, geological mapping, geochemical sampling, and structural analysis to prioritize targets for future trenching and drilling. The approach is to develop targets quickly and efficiently. A variety of lithologies observed in mine workings, including basalt, siltstone, and other metasediments, suggest a variety of potentially favourable lithologies and structures to test.

Auracle Geospatial Science Inc. (‘Auracle’) was contracted by Sranan to analyze the structural complexity of the Lawantino Property by means of its proprietary Mapped Underworld Dimension (MUD® SAR) remote-sensing system. Results from Auracle’s analysis show a distinct increase in fracture density in association with abundant small-scale miners (see Figure 3). A similar increase in fracture density is observed on the east portion of the Lawantino Property.

Lawantino Agreement Terms

Pursuant to the terms of the Agreement, dated February 5, 2026, Sranan may earn a 100% interest in the Property by making cash and share payments and completing exploration-related expenditures. Over a 5-year period, the Company may earn 90% interest in the Property by making total cash payments of US$1,900,000, issuing 1,800,000 common shares to the arm’s-length Vendor, and completing exploration expenditures on the Property totaling US$1,700,000. Upon completion of the 90% earn-in, the Vendor will retain a 10% interest in the Property and a 2% net smelter return royalty (‘NSR’) on all metals production from the Property. There was no finder fees paid.

Sranan may repurchase the 2% NSR for US$3.0 million and, upon the establishment of a minimum 750,000-ounce measured and indicated gold resource, may acquire the remaining 10% interest in the Property based on an independent valuation.

Dr. Dennis LaPoint, EVP of Exploration and Business Development, states, ‘I am very excited about this new acquisition along the same structural trend of the CGSZ that hosts two active gold exploration projects. Lawantino complements our ongoing drilling program at our Tapanahony Gold Project and demonstrates that Sranan will continue to expand our portfolio of gold projects based on our extensive knowledge of Suriname. The agreement with Lawantino N.V. represents a major step in expanding our footprint within Suriname’s highly prospective southeastern part of the Marowijne greenstone belt along one of the major controlling structures for large gold deposits. A strength of the Sranan team is our ability to develop early-stage projects into potential new discoveries. I first reviewed this area in 2007 when held by Canarc, so I am very pleased with our cooperation and relationship with Lawantino shareholders.’

Samples were prepared and assayed by Filab in Paramaribo, Suriname. All samples >2 g/t Au were re-assayed with 50-gram re-assay and gravimetric assay. Standard QA/QC procedures were followed and showed a satisfactory level of reproducibility. The Company notes that the drill intercepts may not represent true underlying mineralization. Core logging, photography, and sampling are completed under strict industry standard QA/QC protocols (Oreas certified reference materials, assayed coarse blanks, duplicates of core).
