Solaris Resources (TSX: SLS)(OTCQB:SLSSF) has reported assay results from numerous boreholes, which were aimed at expanding mineral resources at the Warintza Project, located in southeastern Ecuador. A visual representation of the results can be found in Figure 1, while Tables 1-2 provide detailed results.
Warintza East, discovered in July 2021, had eight drill holes incorporated into the Warintza Central Mineral Resource Estimate in April 2022. Further drilling operations have notably enlarged the size of the deposit, with drilling efforts set to augment resource growth in various directions, including north, northeast, east, and southwest.
Warintza Southeast, a distinct, higher-grade porphyry center south of Warintza East, was identified in May 2023. Positioned beyond the MRE’s boundary, it presents a prospect for adding higher-grade mineral resources. Presently, deeper drilling is being executed, with considerable step-outs toward the southeast in the pipeline. The findings draw from discovery hole SLSE-28, which unveiled a 301m open-ended interval of 0.65% CuEq² in an advantageous andesite porphyry host (Refer to the press release dated June 1, 2023). This data assists in establishing the system’s upper part’s geometry and offers vectors for additional drilling.
Hole SLSE-29 was launched east of SLSE-28 and drilled southeast to the KD-200 rig’s limit, going through a less receptive intermineral diorite porphyry. It returned 175m of 0.50% CuEq² within 289m of 0.40% CuEq² from near the surface. The last 105m averaged 0.60% CuEq², with depth remaining open.
Hole SLSE-30, commenced west of the discovery hole SLSE-28, was drilled southeast to the KD-200 rig’s limit. It yielded 30m of 0.53% CuEq² from near the surface within a wider interval of 275m of 0.48% CuEq². The concluding 41m averaged 0.60% CuEq², still open to depth.
Current operations are underway for deeper drilling that targets extensions of higher-grade intervals observed at the end of each hole. In addition, two more platforms are being developed for step-outs 250m and 500m to the southeast. This area has previously recorded XRF³ values of 0.3% to 0.5% Cu in andesite porphyry.
Highlights from the results are as follows:
Warintza East was discovered in July 2021, with eight drill holes included in the Warintza Central Mineral Resource Estimate (“MRE”)¹ in April 2022. Subsequent drilling has significantly expanded the dimensions of the deposit, with drilling targeting further resource growth to the north, northeast, east and southwest.
- SLSE-27 was collared on the eastern limit of the Warintza East drill grid and drilled vertically to the limit of the KD-200 rig, returning 132m of 0.60% CuEq² from near surface within a broader interval of 246m of 0.55% CuEq², bottoming in mineralization and remaining open at depth
- SLSE-26 was collared 100m north of SLSE-27 and drilled vertically to the limit of the KD-200 rig, returning 212m of 0.52% CuEq² within a broader interval of 310m of 0.45% CuEq² from surface, ending in mineralization and remaining open at depth
- Step-out and deeper drilling is planned with two platforms under construction and a further six scheduled to extend the drilling grid to the north, northeast, east, and southwest
Warintza Southeast was discovered in May 2023 as a distinct, higher-grade porphyry center to the south of Warintza East beyond the limit of the MRE and offers potential to add higher-grade mineral resources, with deeper drilling underway and significant step-outs to the southeast planned.
- These holes follow discovery hole SLSE-28, which returned an open-ended interval of 301m of 0.65% CuEq² in a favourable andesite porphyry host (see press release dated June 1, 2023), and helps establish the geometry of the upper part of the system and vectors for further drilling
- SLSE-29 was collared east of SLSE-28 and drilled southeast to the limit of the KD-200 rig through a less receptive intermineral diorite porphyry, returning 175m of 0.50% CuEq² within 289m of 0.40% CuEq² from near surface, with the final 105m averaging 0.60% CuEq² and open to depth
- SLSE-30 was collared west of discovery hole SLSE-28 and drilled southeast to the limit of the KD-200 rig, returning 30m of 0.53% CuEq² from near surface within a broader interval of 275m of 0.48% CuEq², with the final 41m averaging 0.60% CuEq² and remaining open to depth
- Deeper drilling targeting extensions of higher-grade intervals noted at the end of each hole is underway and two additional platforms are under construction for step-outs 250m and 500m to the southeast where XRF³ values of 0.3% to 0.5% Cu in andesite porphyry were recorded
