Questcorp Mining Inc. (CSE: QQQ) (OTCQB: QQCMF) (FSE: D910) (the “Company” or “Questcorp”) is pleased to announce that, further to its news release dated May 6, 2025, the Company has issued 6,285,722 common shares in the capital of the Company (the “Common Shares”), representing 9.9% of the issued and outstanding Common Shares as of May 20, 2025, to Riverside Resources Inc. (“Riverside”) and completed the required payment of $25,000 CAD to Riverside, all pursuant to the terms and conditions of the option agreement among the Company, Riverside and its wholly-owned subsidiary, RRM Exploracion, S.A.P.I. De C.V, dated May 5, 2025, in respect of the 2,520.2 hectare La Union carbonate replacement project located in Sonora, Mexico (the “La Union Project”).

The La Union Project

The La Union Project is a carbonate replacement deposit (“CRD“) project hosted by Neoproterozoic sedimentary rocks (limestones, dolomites, and siliciclastic sediments) overlying crystalline Paleoproterozoic rocks of the Caborca Terrane. The structural setting features high-angle normal faults and low-to-medium-angle thrust faults that sometimes served as mineralization conduits. Mineralization occurs as polymetallic veins, replacement zones (mantos, chimneys), and shear zones with high-grade metal content, as shown in highlight grades of 59.4 grams per metric tonne (g/t) gold, 833 g/t silver, 11% zinc, 5.5% lead, 2.2% copper, along with significant hematite and manganese oxides, consistent with a CRD model (see the technical report entitled “NI 43-101 Technical Report on the Union Project, State of Sonora, Mexico” dated effective May 6, 2025 available under Questcorp’s SEDAR+ profile). These targets also demonstrate intriguing potential for large gold discoveries potentially above an even larger porphyry Cu district potential as the Company’s target concept at this time.

Questcorp cautions investors grab samples are selective by nature and not necessarily indicative of similar mineralization on the property.

Riverside, the operator of the La Union Project, is currently lining up the various geophysical contractors to immediately undertake orientation surveys and follow up detailed survey to confirm and enhance the drill targets.

Early-stage exploration results align with proven discovery model in the Segovia district.

Quimbaya Gold Inc. (CSE: QIM) (OTCQB: QIMGF) (FSE: K05) (“Quimbaya Gold” or the “Company”) is pleased to announce initial results from the recently initiated field programs at its Tahami South Gold Project in Antioquia, Colombia. Current work includes detailed geological mapping, rock channel sampling, stream sediment surveys, and soil sampling, all designed to refine and prioritize targets ahead of the Company’s maiden drill campaign scheduled to commence in Q2 2025 (Figure 1).

The Tahami South Project is located within one of Colombia’s most prolific gold-producing regions, the Segovia-Zaragoza belt and sits just 1.8 kilometres northeast of Aris Mining’s flagship Segovia operation, which contains over 13.8 million ounces of gold, and continues to host one of the country’s most robust resource bases (Historical production 7,962 Moz, M &I resources 3,629 Moz, inferred resource 1,823 Moz; Wilson & Redwood, 2010; De Marc et al., 2023).

Recent surface exploration by Quimbaya Gold has further validated the geological prospectivity of the area, returning high-grade gold values up to Au@ 11.21 g/t & Ag@ 6 g/t for grab rock, and Au@ 1.4 g/t & Ag@ 23.3 g/t for panel rock sample, supported by classic epithermal pathfinder geochemistry and strong structural control (figure 2). Together, these results align closely with known mineralization styles in the district and provide a robust technical foundation for the Company’s upcoming drill campaign in Q2 2025 – an initiative aimed at unlocking a potentially significant high-grade vein system along this underexplored extension of the Segovia trend.

Key Technical Highlights

• Surface rock sampling at Tahami South returned high-grade gold values up to 11.21 g/t Au, with multiple samples exceeding 1 g/t, supporting the company’s thesis of a robust precious metal system at surface. These results were generated from 60 channel and grab samples across 144 hectares of jungle-covered terrain – an early-stage success that underscores the potential of the target area.

• In addition to strong gold values, the geochemical suite includes consistently elevated levels of key pathfinder elements such as arsenic (As), antimony (Sb), copper (Cu), lead (Pb), and zinc (Zn) – all characteristic of epithermal to intermediate sulfidation systems found along the Segovia-Zaragoza trend. Select samples also returned anomalous Molybdenum values up to Mo@ 70 ppm, further supporting the potential for structural overprinting or hybrid mineralizing events. Collectively, these signatures reinforce the project’s alignment with the geological architecture and mineralization styles that have yielded some of Colombia’s most significant gold discoveries.

• The company’s use of geologic mapping, Lidar, and systematic geochemical sampling follows discovery techniques that, as documented by Dr. Stewart Redwood, have accounted for the majority of significant gold finds in Antioquia over the past 50 years.

• This detailed technical groundwork is a deliberate and essential step in Quimbaya’s exploration strategy, helping to refine and prioritize the most compelling targets for the Company’s upcoming drill campaign in Q2 2025. By advancing this program with precision and discipline, the team is building a stronger foundation for success – one rooted in geological confidence and targeting certainty. These early-stage results not only validate the exploration model but also enhance the Company’s conviction in the broader potential of Tahami South as a district-scale, high-grade gold system.

“Tahami South exhibits all the essential hallmarks of a fertile gold system at the reconnaissance stage: strong surface gold grades, well-developed quartz-sulfide veining, and a classic pathfinder suite including arsenic, antimony, lead, and zinc – all within a structural corridor that aligns with known productive trends in Antioquia. These are the types of indicators that have preceded many of Colombia’s most significant discoveries. When supported by systematic mapping and geochemistry, as Quimbaya is doing here, such signatures significantly enhance the probability of drilling into a meaningful mineralized system.” Dr. Stewart D. Redwood, Economic Geologist & SEG Fellow.

Connecting Structure, Geochemistry and Scale

Exploration at Tahami South is being guided by a disciplined, model-driven approach that integrates structural mapping, geochemical data, and high-resolution topographic analysis to define the structural controls on mineralization. Recent work has outlined a network of northeast- and east-west-trending quartz veins and hydrothermal breccias hosted within andesitic and intrusive rocks – a structural architecture closely aligned with productive corridors in the Segovia district. Lidar interpretation and field mapping have revealed vein exposures and alteration zones that correlate with elevated gold and pathfinder element values, including arsenic (As), antimony (Sb), copper (Cu), lead (Pb), and zinc (Zn). These features, taken together, suggest an intermediate-sulfidation epithermal system with potential for multiple mineralized shoots. The geochemical vectoring – particularly where pathfinder anomalies overlap key structural intersections – is now informing high-priority targets as the Company prepares for its inaugural drill campaign. The scale and coherence of these features suggest the potential for a significant mineralized system emerging within an underexplored extension of the Segovia trend.

“Everything we’re seeing tells us we may be sitting on something significant, and that’s why we’re taking a disciplined and methodical approach. When you test a system like this for the first time, it is very important to get everything right, and this foundation gives us strong conviction heading into our upcoming drill campaign, and we’re excited about what’s ahead.”
