The Company secured exploration rights and an option to purchase a group of claims in the Pyramid Mining District of Nevada in May 2019.
The project is located 25 miles northwest of Reno and is readily accessible from State Highway 445 which crosses the northwest tip of the project.
The Pyramid Mining District lies at the northwest end of the Walker Lane mineral belt which is host to numerous past and currently producing multi-million ounce epithermal gold deposits as well porphyry copper and porphyry molybdenum deposits.
The Company’s claim interests cover the Ruth vein system and a number of parallel vein systems and zones of alteration. In addition to abundant quartz and pyrite, vein minerals in unoxidized ore from the Ruth vein system include barite, anglesite, galena, sphalerite, acanthite, gold, and cassiterite.
In 2020 the Company carried out a soil sampling programme. This confirmed a historic soil anomaly over the “Western Line” over a strike length of 1000m with values up to 349ppb gold (0.35 g/t Au) and 22 ppm silver. Wider spaced sample lines to the southeast suggesting a possible 750m extension to the Western Line Anomaly where infill sampling has been completed and results are awaited.
The survey also identified two new, untested soil anomalies, anomalous for both gold and silver. The first of these appears to be a splay off Western Line (the Western Splay Anomaly) and has a length of 550m open to the south. The second is an 800m-long anomaly located to the northeast of the Western Line Anomaly and follows a northern projection of the Ruth Mine vein system (the “North Ruth Anomaly”).
Follow up prospecting has identified areas of silicified and brecciated Tertiary-age volcanics at the North Ruth Anomaly and samples of spoil from an old shaft were analysed to contain 314 g/t silver (9.16 ounces/ton) amongst eight samples averaging 91 g/t silver (2.67 ounces/ton) and 0.26 g/t gold.
Seven rock chip samples were taken from within the open ended 900m length of the Western Line soil anomaly, at the northwest and southeast ends, due to limited outcrop in between. The samples averaged 1.49 g/t gold and 99 g/t silver (2.89 ounces/ton) with a maximum value of 6.29 g/t gold and 158 g/t silver (4.61 ounces/ton) from a select rock chip sample of a narrow vein exposed at the collar of an old shaft.
Five of the samples were taken at the southeast end of the anomaly over an anomaly width of approximately 60m. These samples averaged 0.77 g/t gold and 104.11 g/t silver, with the best sample returning 1.43 g/t gold and 327 g/t silver from a 0.30m outcrop channel sample. An additional 2 samples located approximately 900m further southeast were taken in what is interpreted to be a potential extension to the Western Line. Both samples contained anomalous Au/Ag with Sample PR 29 returning 0.49 g/t Au and 51 g/t Ag. Numerous prospector pits follow the strike of the anomaly suggesting a total length of up 1,700m.
Phase 1 trenching was restricted to the North Ruth and Western Line soil anomalies where they fall within the private land portion of the Pyramid Property under lease to the Company. Six trenches were dug in April 2021 to expose bedrock over continuous sections of these two anomalies.
Two trenches, Nos. 1 and 2, were located over the north and south ends of the North Ruth anomaly respectively. Assay results from Trench No.1 revealed a 45.7m continuous width of mineralisation grading 61ppm silver (1.78 ounces/ton) and 0.09ppm gold starting 42.67m from the east end of the trench and continuing up to the western end where it ended in mineralisation.
This 45.7m section contained two separate higher-grade zones of 9.14m grading 146 g/t silver (4.27 ounces/ton) and 0.10 g/t gold and 3.05m grading 99 g/t silver (2.88 ounces/ton) and 0.15 g/t gold. The silver bearing zone is flanked on the eastern side by a 9.14m wide zone with higher gold values averaging 0.54 g/t gold and 11 g./t silver.
The next nearest trench, Trench No.2, some 460m along strike, cut 3.05 m grading 260 g/t silver (7.58 ounces/ton) and 0.27 g/t gold.
Four other trenches were cut at spacings of between 95m to 250m over a 470m strike length of the Western Line soil anomaly and cut through a number of narrow zones of low-grade gold and silver mineralisation as shown in the table below. Further work on the Western Line soil anomaly, at least within the private land portions of the property, is not currently a priority.
The silver mineralisation in Trench No.1 occurs within a quartz latite tuff showing varying levels of epithermal argillic alteration and silicification. Additional infill soil sampling has been completed on the south end of the project area, on public lands secured by mining claims, and results are awaited.
In August 2021, the Company conducted a Phase 2 trenching programme at Pyramid using a larger and more powerful excavator to further define surface silver mineralisation at North Ruth and test additional gold and silver in soil anomalies located on the public land portions of the Project Area. Five trenches (numbers 1 EXT, 7, 8, 10 and 11) were completed for a total of 443m. Three trenches (1 EXT, 7 and 8) were located at North Ruth to follow up on the positive results of the Phase 1 trenching programme.
Trench 1 EXT was designed to deepen and extend Trench No. 1 to better define the width of mineralisation at that location. Trench 1 EXT extended the grade of the mineralisation cutting 58.98m of continuous silver mineralisation grading 73g/t silver (2.14 ounces/ton) with 0.13g/t gold. This includes two high grade intervals of 3.35m grading 218g/t silver (6.37 ounces/ton) with 0.25g/t gold and 2.13m grading 595g/t silver (17.35 ounces/ton) with 0.66g/t gold. The latter high-grade intersection is within that part of trench 1 EXT that extended Phase 1 Trench 1.
Trenches, No. 7 and No. 8, were excavated along strike from Trench 1 EXT. Trench No.7, located approximately 73m to the northwest, cut 2.44m grading 64g/t silver (1.88 ounces/ton) with 0.47g/t gold. Trench 7 was not able to be completed to its full planned width due to the steepness of the slope.
Trench 8 was located 65m southeast of Trench 1 EXT and approximately 395m northwest of Phase 1 Trench 2 which previously reported an intersection of 3.05 m grading 260 g/t silver (7.58 ounces/ton) and 0.27 g/t gold. Trench 8 cut 26.80m grading 37g/t silver (1.08 ounces/ton) with 0.12g/t gold which included a higher-grade zone of 6.09m grading 102g/t silver (2.96 ounces/ton) with 0.26g/t gold. Trench 8 also cut a separate gold bearing zone 6.09m wide grading 0.73g/t gold with negligible silver.
Two additional trenches were located on the public land portions of the Project Area to test the Western Line and Western Splay soil anomalies. Narrow zones of mineralisation were encountered in both trenches. Results include 0.6m grading 78g/t silver (2.27 ounces/ton) and 0.45g/t gold from Trench 10 and 1.2m grading 6g/t silver (0.16 ounces/ton) and 1.65g/t gold in Trench 11.
Taken together, trenches 1, 1 EXT, 2, 7 and 8 define a zone of silver mineralisation at North Ruth that is at least 530m long.
