GEOLOGY AND MINERALIZATION

The Labrador Trough, straddling parts of Labrador and Québec, is known for Superior-type iron formations that have been explored and mined for iron since 1954. The principal iron formation unit of the area, is the Sokoman Formation, a 30 to 350 metre-thick iron-rich stratigraphic unit running along the length of the Labrador Trough. The lower and middle members of the Sokoman Formation are the most economically important, responsible for world-class iron-ore deposits commonly containing more than 50% hematite and magnetite. The Property is positioned over a synclinal fold structure affecting the Sokoman Formation (Figure 2) and is viewed as favourable for iron mining in the district.

HISTORICAL RESOURCES

Mineral exploration at the Property began in the 1970s when the Iron Ore Company of Canada conducted reverse circulation (‘RC’) drilling, diamond drilling, and trenching, producing a mineral inventory on the Property in 1982. In the decade following 2006, Labrador Iron Mines Ltd. conducted diamond drilling and RC drilling, along with LiDAR surveying and airborne gravity and magnetic surveying over the Property, and commissioned an inaugural mineral resource estimate (‘MRE’) for the Property in 2012 which was updated in 2014. The 2014 MRE is summarized in Table 1.

Table 1: Knob Lake Property Historical Mineral Resource Estimate (Dupéré, 2014)¹

¹The mineral resource for the Knob Lake Deposit (Dupéré, 2014) is considered historical in accordance with NI 43-101 (see paragraph below for important disclosures regarding historical resources)
²Historical mineral resources are rounded to the nearest 10,000 tonnes

Riverside Resources Inc. (TSXV: RRI) (OTCQB: RVSDF) (FSE: 5YY) (‘Riverside’ or the ‘Company’), is pleased to announce that the next stage of exploration is now progressing, following the successful completion of the joint Q4 2024 drilling program at the Cecilia Gold Project in Sonora, Mexico. The drill program was conducted in partnership with Fortuna Mining, which continues to advance their earn-in option on the project (See news release: March 13, 2024). Riverside, acting as the operator, completed an initial five-hole, 2,250-meter drilling campaign designed to test four distinct target areas generally with one geological evaluation drill hole per target to seek scale and evidence of a potentially strong hydrothermal system which would set up for a follow up 2025 exploration program which has now begun. The drilling in Q4 hit favorable indicators as outlined below and continued to develop the district scale targets both at Cerro Magallanes and on the broader >60 km sq property package with vast areas to expand.

The drill program announced in September (See press release: September 10, 2024), where Riverside outlined its goals to define and expand key targets at Cecilia. The latest program hit gold mineralization in each target area and broader epithermal alteration consistent with target styles like the nearby Mercedes Mine Sonora and Oatman Gold District Arizona. At Magallanes Hill, two holes were drilled at the San Jose target, followed by one hole on the eastern flank, referred to as the East Target. Additionally, two holes were drilled in the Mesa area to the south: one testing the Mayra Vein concept and the final hole drilled eastward to intersect the Mesa Fault, a significant structural target.

‘We are encouraged by the results of the Q4 2024 drilling program, which focused on testing geological features with limited previous drilling, just one or two holes in each area, and yielded positive indicators while also uncovering some unexpected geologic surprises,’ said John-Mark Staude, President and CEO of Riverside Resources. ‘This program not only confirmed earlier gold intercepts but also expanded the scale of exploration with significant step-outs and new target areas. The ongoing work underscores our commitment to unlocking new opportunities and delivering sustained value to our stakeholders.’

Highlights of the Drill Program:

San Jose Vein System (North Breccia): Two holes were drilled to extend testing of this structure, building upon results from previous drilling and assay work. The San Jose system has shown significant mineralization potential, as highlighted in prior programs including samples returning values of up to 48.3 g/t Au over 0.75 m at surface (See press release: January 28, 2021). Drilling to depths of 500 to 800 meters successfully intersected the San Jose structure in both holes, confirming the continuity of this extensive vein system. Notably, hole CED24-010 returned an intercept of 3.41 g/t Au over 4 meters, starting at a depth of 76 meters, with an additional lower intercept including 0.39 g/t Au over 5.25m starting at 319m identified along the projected extension of the San Jose vein which topographically is over 500m below the Magallanes peak and previous drill intercepts in the upper part of the San Jose vein system. These results are illustrated in the cross-section below.

East Target: A single hole was drilled perpendicular to known mineralization identified in surface samples and previous drilling by Cambior (1996). This hole crossed through thick zones of alteration, adding valuable geological data for this target and confirming that Cecilia has strong feeder zones for gold. The hole intersected at least 6 gold bearing intervals with one being 0.38 g/t Au over 1.75m starting from 149.25m. This hole was drilled eastward in order to constrain the dip as past drill holes had been drilled westward. The single new hole intercepted multiple veins for this part of the eastern Magallanes system as shown on the map below and on the Company website

Mesa Ranch Area (Mayra Vein): The 2024 program was the first time the Mayra Vein has been tested with this the first drill to be conducted on the broader Cecilia project, which encompasses over a dozen identified targets. This hole was intended to test the northwest trending epithermal veins related with felsic dikes that potentially feed toward and likely cut the Puma Dome. These district-scale targets from the Mesa Ranch area have potential along strike for further exploration. Core drill hole CED24-011 intersected multiple vein zones, including an interval of 0.21 g/t Au over 2 meters starting at 281 meters. The gold-bearing interval featured quartz veining and oxides whose projection aligns with surface-sampled veins that extend over 700 meters along strike, further highlighting the potential and continued interest in these vein systems.

South Mesa Fault Zone (Mesa South): The final hole of the program focused on the extensive South Mesa Fault; a 10 km-long structure comparable to fault-controlled gold systems like those in Nevada’s Midas District. Drill hole CED24-012 intersected the fault at 110m and comprises a 5m thick interval of sheared brecciated rock which can be projected to surface and followed along strike. Surface samples returned gold values of over 2 g/t gold along the surface projection of this fault. Plans are in place for additional exploration of the Mesa South region for the first half of 2025, which will include tracking the Mesa fault’s continuity along strike.

The table below summarizes the locations and depths for the five holes completed in this first drilling round with Fortuna Mining.

The drilling location map below shows the 5 holes (3 drill pads) which correlate with the drill hole descriptive table above. Drill hole CED24-008 at Magallanes was deeper than any previous drilling. Figure 1 shows the drill traces as they intersected the down dip projection of the veins.

Figure 1– Geology map and location of the five 2024 drill holes shown in red. The straight and thin black lines near Magallanes are drill holes from previous campaigns. This new program stepped out to test the East Target (CED24-009) and the Mayras and South Mesa with single holes.

The cross-section figure below highlights hole CED24-010 from the drill program, which demonstrates the intersections of multiple vein structures. These structures are now interpreted to potentially extend over 800 meters vertically, suggesting they could be part of a significant epithermal system. Further exploration is planned for 2025, including an MT (Magneto-telluric) geophysical survey to refine our targeting of the system. Based on the results of these surveys, additional drilling may be undertaken to further evaluate the system’s potential. The Project includes numerous untested targets throughout the 60 km sq land package.

This drill program advanced the understanding of the Cecilia system’s geology, confirming significant low-sulfidation epithermal features in the Cerro Magallanes area. Data from the drilling suggests the mineralization system is tilted southeast, supported by surface mapping, geochemical analysis, and structural modeling.

The Cecilia Gold Project continues to demonstrate significant potential. Fortuna Mining’s technical expertise and funding have enabled systematic exploration, with the partnership potentially targeting a larger follow-up program in 2025. The drilling positively demonstrated scale and alterations consistent with a mineralized system worthy of more advanced drilling in addition to continued target testing.
