Quimbaya Gold Inc. (CSE: QIM,OTC:QIMGF) (OTCQX: QIMGF) (FSE: K05) (‘Quimbaya’ or the ‘Company’) reports the completion of drone-based magnetic and radiometric surveys covering approximately 800 hectares of the Tahami Center concession. The survey area includes zones where geological reconnaissance and sampling have identified features interpreted as potentially associated with a porphyry-style copper system. These features define a prospective surface trend of approximately 3.1 km by 1.3 km.

Highlights

• High magnetization vector intensity (MVI) anomalies show two subvertical zones dipping to the southeast. These are interpreted to be porphyry intrusions. They coincide with the mapped porphyry-style potassic alteration and veining with anomalous Cu, Au and Mo geochemistry.

• A MVI low anomaly on the SE side coincides with the mapped lithocap in which alteration is magnetite-destructive.

• Magnetic anomalies interpreted to be associated with a porphyry intrusive suite extend over approximately 3.1 km in length and 1.3 km in width, with a dominant northwest-southeast orientation (Figure 1).

• Pad locations for the maiden drilling program at the Tahami Center target area will be defined following the completion and integration of soil, rock and stream sediment geochemical assay results, detailed geological mapping, and preliminary 3D geological – geophysical modeling. This work is expected to be finalized this month.

‘The work completed to date at Tahami continues to strengthen our confidence in the exploration potential of the project,’ said Alexandre P. Boivin, CEO of Quimbaya Gold. ‘This survey materially strengthens our technical thesis at Tahami Center. We are seeing a large, coherent subsurface magnetic system that aligns with mapped surface mineralization and alteration. That level of consistency supports advancing confidently toward drill testing as we define our initial targets.’

‘The presence of well-developed porphyry-style veinlets at surface is considered significant in the context of the Company’s exploration model for a porphyry copper-gold-molybdenum system,’ stated Ricardo Sierra, B.Sc., MAusIMM, Vice President Exploration and Qualified Person. ‘Geophysical cross-sections and a plan view at approximately -700 meters in elevation (Figure 2) demonstrate a spatial correlation between the mapped surface porphyry-style mineralization and a projected subsurface magnetic high identified in the recently completed airborne magnetic survey. These magnetic anomalies may reflect zones of increased magnetite content, which in porphyry systems can be associated with potassic alteration. This interpretation is conceptual in nature and has not yet been confirmed by drilling. Confirmation will require diamond drilling and the integration of pending radiometric survey, soil and rock geochemical assay results.’

Detailed geological mapping has identified an area interpreted as a preserved lithocap in the east – southeastern portion of the mining concession. This zone spatially coincides with low magnetic susceptibility values observed in the MVI survey. The reduced magnetic response is interpreted to reflect magnetite destruction associated with intense advanced argillic alteration. This alteration is locally associated with quartz vein systems in which gold, silver, and copper mineralization has been identified through surface sampling.

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.

Transition Metals Corp. (TSXV: XTM) (‘Transition’, ‘the Company’), is pleased to announce that it has vested a 100% interest in the Pike Warden property, a porphyry-epithermal exploration asset located in southern Yukon. This acquisition consolidates the Company’s control over the property and positions it for continued exploration activities and partnering opportunities. The Company will seek a partner to more aggressively explore the large mineralized system opportunity.

‘This acquisition represents an important step in expanding Transition Metals’ portfolio of high-quality exploration assets,’ said Scott McLean, CEO of Transition Metals. ‘The Pike Warden property has strong exploration potential, and the work carried out by Transition to date has identified over 30 high grade Au-Ag epithermal and Cu-Mo porphyry showings, which together with the geophysical and mapping data demonstrate a large porphyry and epithermal mineralizing system.‘

Terms of Vesting

The project was optioned from a local geologist in 2022 (see news release dated June 28, 2022). The Company has vested its interest by paying the Optionor $120,000, issuing 1,000,000 shares, and spending $1,000,000 in exploration over the four-year period. The Optionor retains a 1% Net Smelter Return royalty on the Property.

Financing

The Company is pleased to announce that it intends to raise up to $1,000,000 by way of a non-brokered private placement consisting of up to 8,695,652 Charity Flow Through Units (the ‘CFU‘) at a price of $0.115 per CFU. The initial Purchasers of the CFU may subsequently donate such CFU to registered charitable organizations, who may in turn choose to sell such CFU Units (the ‘Re-Offered Units’) to purchasers at a price of $0.08 per Re-Offered Unit (the ‘Re-Offer Price’) or sell such Re-Offered Units to purchasers at the Re-Offer Price. The Company will not be a party to any such arrangements. The Re-Offered Units will consist of a common share and a half warrant. Each full warrant entitles the investor to purchase a common share in the Company at any time for $0.115 for a period of 18 months. A finder’s fee may be paid in connection with the Offering to finders, as determined by mutual agreement between the Corporation and the finders and subject to regulatory approval. The finders’ fee will consist of 6% cash for Units sold to investors introduced by such finders, and non-transferable share purchase warrants equal to 6% of such CFU sold to investors (‘Compensation Warrants’). The Compensation Warrants will permit the purchase of one common share in the capital of the Company for 18 months from closing at a price of $0.115.

Proceeds from the CFT Shares issued in connection with the Offering will be used to explore and advance critical minerals properties in Ontario (Saturday Night PGM) and Northwest Territories (Dessert Lake U) as well as Ontario precious metal project (Gowganda Au). The securities issued in connection with the Offering, including any common shares issued upon exercise of the Compensation Warrants, will be subject to a four-month restricted resale period and applicable securities legislation hold periods outside of Canada from the closing date. Completion of the Offering will be subject to all necessary approvals, including the approval of the TSX Venture Exchange.

Radisson Mining Resources Inc. (TSXV: RDS,OTC:RMRDF) (OTCQB: RMRDF) (‘Radisson’ or the ‘Company’) is pleased to report an updated Mineral Resource Estimate (‘MRE’) at its 100%-owned O’Brien Gold Project (‘O’Brien’ or the ‘Project’) located in the Abitibi region of Québec. The Company is currently undertaking a fully-funded 140,000-metre step-out drill program at the Project with the objective of determining the scope of mineralization to a depth of 2 kilometres. This program commenced in 2025 and is expected to continue through the first half of 2027. Today’s updated MRE is an interim report that demonstrates the impact of recent drilling successes completed as of December 31, 2025. Highlights include:

• 82% increase in Inferred Mineral Resources from step-out drilling intersecting new mineralization, with 1.69 million ounces (‘Moz’) in 10.37 million tonnes (‘Mt’) at 5.08 grams per tonne (‘g/t’) gold (‘Au’);

• 8% increase in Indicated Mineral Resources with 0.63 Moz in 3.49 Mt at 5.59 g/t Au;

• Estimated using US$2,500/oz Au and 2.2 g/t Au cut-off, with a refined geological model and capping strategy, establishing the go-forward basis for future, modern mine development.

Matt Manson, President and CEO: ‘Today we report the first of several planned, step-by-step updates to the MRE at the O’Brien Gold Project, quantifying the impact of our recent drilling success and establishing a clear foundation for future, modern mine development. With just 25% of our 140,000 metre step-out drill program completed, the new vein mineralization delineated beneath the historic mine workings and the previous mineral resource volume (Radisson news release dated February 12, 2026) has resulted in an 82% increase in the quantity of Inferred Mineral Resources, now 1.69 Moz (10.37 Mt at 5.08 g/t Au). At the same time, we have refined the estimate of Indicated Mineral Resources, incorporating more tonnes at a lower average grade for an 8% increase in contained ounces, now 0.63 Moz (3.49 Mt at 5.59 g/t Au). Our estimates utilize a 2.2 g/t Au cut-off at a reasonable gold price assumption of US$2,500/oz.’

‘The former O’Brien Mine was known for high-grade ore-shoots mined in small volumes. Mining ended in 1957 with the gold price at US$35/oz. Significant volumes of mineralized vein material, below what we believe to have been a 7 g/t to 8 g/t Au cut-off, were left untouched. Now, we are presenting the Project as it should be viewed for future development: not as a bespoke deposit of extreme grade and limited scale, but as an extensive Abitibi vein deposit with a substantial inventory of mineralized material amenable to modern mechanized mining at higher throughput.’

‘Our step-out drill campaign at O’Brien is ongoing with up to eight rigs. We expect to complete 72,500 metres in 2026 and 32,500 metres in the first half of 2027. This is in addition to the meterage supporting today’s updated MRE. The vein mineralization system we have been intersecting is open at depth. In fact, since our step-out drilling began in the fall of 2024, we have been seeing an impressive 84% success rate in intercepting classic O’Brien quartz-sulphide-gold veins with grades and thicknesses consistent with today’s updated MRE. Looking to a 2-kilometre exploration floor, we believe an appropriate Exploration Target at O’Brien is another 5 Mt to 10 Mt at grades of between 4.0 g/t and 6.0 g/t Au containing 0.6 Moz to 2.0 Moz. We expect to complete further step-by-step updates to the MRE as our drilling progresses.’

Cautionary statement: Readers are cautioned Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, socio-political, marketing, or other relevant issues including risks set forth in Radisson’s filings made with Canadian securities regulatory authorities. The potential quantity and grade of an Exploration Target is conceptual in nature, there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.

A video presentation of today’s news by Matt Manson can be found at https://www.youtube.com/watch?v=5IZwSSYbO70.

Mineral Resource Estimate (effective January 31, 2026)

The MRE is based on 428,440 metres of drilling completed to the end of December 31, 2025, and has been authored by SLR Consulting (Canada) Ltd. (‘SLR‘). The estimate utilizes a 2.2 g/t Au cut-off at US$2,500/oz and makes certain assumptions on mining and processing costs, currency exchange rate, and metallurgical recovery (Table 1 and Figure 1). A wireframe vein model prepared by Radisson and reviewed by SLR constrains the estimate and applies a minimum width of 1.2 metres. Individual assays are capped at 60 g/t Au prior to compositing to full width of the veins, and the block model utilizes 5 by 2 by 5 metre blocks consistent with recent mine design studies.

Table 1: Mineral Resource Estimate, Effective January 31, 2026

An MRE for the Project was previously published in March 2023 (Radisson news release dated March 2, 2023) based on 325,509 metres of drilling completed to the end of 2022. Indicated Mineral Resources (effective March 2, 2023) were estimated at 0.50 Moz (1.52 Mt at 10.26 g/t Au) with additional Inferred Mineral Resources of 0.45 Moz (1.60 Mt at 8.66 g/t Au). The 2023 study applied a 4.5 g/t Au cut-off at US$1,600/oz Au.

In July 2025, Radisson published a Preliminary Economic Assessment (‘PEA‘) for the Project that utilized the 2023 estimate re-blocked by SLR in the Z-direction from 10 metres to 5 metres to allow for more flexible underground mine design. A cut-off of 2.2 g/t Au at US$2,000/oz Au and an updated set of economic criteria were applied in the re-blocking exercise consistent with the parameters used for the optimization of the PEA’s underground mine schedule. No other changes were made. Indicated Mineral Resources (effective May 6, 2025) were estimated at 0.58 Moz (2.20 Mt at 8.22 g/t Au) with additional Inferred Mineral Resources of 0.93 Moz (6.67 Mt at 4.35 g/t Au).

The updated MRE released today benefits from 66,387 metres of additional drilling in 122 drill holes conducted between 2023 and 2025, which is the most significant factor in the increase of Inferred Mineral Resources (Figure 2). Radisson has also validated an additional 36,544 meters of historic drilling. The updated MRE utilizes similar estimation parameters to previously, but a more restrictive approach to capping. In the March 2023 estimate, and as incorporated in the re-blocked May 2025

estimate, capping at 40 g/t Au was applied to the full-length composites. In the updated MRE, capping has been applied at 60 g/t Au to the underlying assays prior to compositing. This has the effect of reducing the average grade by approximately 12%, and in the opinion of Radisson and SLR is an appropriate approach to a narrow high-grade vein deposit such as O’Brien.

Compared to previous estimates, the aggregate impact on the Indicated Mineral Resources of the new drilling, the 2.2 g/t Au cut-off, and the updated capping strategy has been to add more tonnes at a lower average grade for an overall increase in contained ounces. The aggregate impact of these three factors on the Inferred Mineral Resources has been the addition of more tonnes at a higher average grade for an overall increase in contained ounces. Indicated Mineral Resources have increased by 8% to 0.63 Moz, based on an increase in tonnes of 58% to 3.49 Mt and a decrease in grade of 32% to 5.59 g/t Au. Inferred Mineral Resources have increased by 82% to 1.69 Moz, based on an increase in tonnage of 55% to 10.37 Mt and an increase in grade of 17% to 5.08 g/t Au.

O’Brien’s system of Quartz-Sulphide-Gold vein mineralization remains open to depth across a broad front beneath the historic mine workings and the updated MRE. The potential continuation of this mineralization to a 2 kilometres depth defines an Exploration Target of an additional 5 Mt to 10 Mt at grades of between 4.0 g/t and 6.0 g/t Au containing 0.6 Moz to 2.0 Moz. The potential quantity and grade of an Exploration Target is conceptual in nature, there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.

A New Vision for the O’Brien Gold Project

The historic O’Brien mine produced over half a million ounces of gold at an average grade exceeding 15 g/t Au. It is clear that the former mine was ‘high-graded’, with manual mining methods applied to the highest-grade veins and ore shoots at an estimated cut-off grade of 7 g/t to 8 g/t Au. Parallel but lower-grade mineralized zones, which would be well above an economic cut-off grade today, were left unmined.

The updated MRE does not incorporate any mineral resources potentially remaining in the former mine. However, in applying the lower grade cut-off of 2.2 g/t Au based on a gold-price estimate of US$2,500, the new estimate captures the overall volume attributes of the O’Brien mineralizing system, with more tonnes and more ounces at a lower average grade. This has the benefit of improving the continuity of mineralization for future mine planning, with larger stopes and more development headings supporting a higher potential mining rate. The Project has existing mining infrastructure to support such a vision, such as a shaft in the former mine extending to a 1,000 metres depth and multiple mills in the region with significant future capacity.

Table 2 illustrates sensitivities on Indicated and Inferred Mineral Resources and the MRE block model based on cut-off grade. These are:

• a) 8.0 g/t Au (US$700/oz) representing the former mine,

• b) 4.5 g/t Au (US$1,250/oz) representing the MRE effective March 2, 2023,

• c) 2.2 g/t Au (US$2,500/oz) representing the updated MRE, and

• d) 1.5 g/t Au (US$3,800/oz) representing the recent long-term consensus price of gold.

The comparison clearly indicates the relationship between volume and grade based on cut-off, the directionality of steeply-plunging grade shoots at O’Brien, and the increased continuity of mineralization achieved at progressively lower cut-offs.

Gold Mineralization at O’Brien and Step-Out Drill Program

Gold mineralization at O’Brien occurs within quartz-sulphide veins developed primarily within the interlayered mafic volcanic rocks, conglomerates, and porphyritic andesitic sills of the Piché Group occurring in contact with the regionally significant Larder Lake-Cadillac Break (‘LLCB’). Individual veins are generally narrow, ranging from several centimetres up to several metres in thickness, and are associated with mineralized alteration envelopes of up to several metres in thickness. Multiple veins occur sub-parallel to each other, as well as sub-parallel to the Piché lithologies and the LLCB. As mapped at the historic O’Brien mine, and now replicated in the modern drilling, individual veins have well-established lateral continuity, with steeply plunging grade shoots developed over significant lengths.

Since the end of 2024, Radisson has been pursuing a program of broad step-out drilling at O’Brien with the objective of determining the overall scope of mineralization at the Project to a depth of 2 kilometres (Figure 1). The priority is the quantity and distribution of mineral resources with step-outs rather than in-filling to upgrade the classification of the existing mineral resources.

This drilling is accomplished with pilot holes followed by wedges and directional drilling to maximize drill efficiency. In October 2025, Radisson announced the expansion of the program to 140,000 metres employing an eventual eight drill rigs (see Radisson news release dated October 16, 2025). An initial 35,000 metres of the program were completed in 2025, with 72,500 metres budgeted for 2026, and a further 32,500 metres scheduled for the first half of 2027.
