The Angus Vein is one of 6 mineralized vein structures identified to date in the Campbell-Crawford prospect and Kuya Silver has intersected mineralized veins in all Campbell-Crawford reported drill holes

Kuya Silver Corporation (CSE: KUYA) (OTCQB: KUYAF) (FSE: 6MR1) is very pleased to announce additional assay results from the Campbell-Crawford area (Table 1; Figure 1). These results include remaining drill hole assay results from hole 23-SK-08 (3.80 m previously reported in Kuya Silver news release dated April 4, 2023), as well as drill holes 23-SK-11, -12 and -13. To date, the Company has reported a total of 1,287 m in four drill holes of a total 2,334 m in seven drill holes at Campbell-Crawford.

Highlights:

• Hole 23-SK-13
  • Angus Vein intersected 5,935 g/t (191 oz/t) silver, 0.06% cobalt over 1.00 m (from 258.19 m) within a wider mineralized zone of 2,424 g/t (77.9 oz/t) silver, 0.03% cobalt over 2.49 m, deeper and along trend from discovery hole 23-SK-08 intersection
  • 5 additional silver or cobalt mineralized veins or vein zones including 151 g/t silver over 1.27 m (from 252.73 m)
• Hole 23-SK-08
  • Mineralized zone of Angus Vein has been widened to 15,372 g/t (494 oz/t) silver over 3.34 m (from 234.90 m) with an additional 514 g/t silver assayed over 0.30 m

  • Registration: https://event.webinarjam.com/channel/KuyaJune2023

Assays are pending for drill holes 23-SK-01 to -06 (North Drummond and Silver Leaf targets, Kerr Lake area) and 23-SK-07, -09 and -10 (Campbell-Crawford area).

David Lewis, Kuya Silver Vice President Exploration, commented: “I am very pleased to report that we have intersected high silver grades over good widths twice in the Angus Vein, first with discovery hole 23-SK-08 and now, 18 m deeper and 10 m along trend, in hole 23-SK-13. Silver in the Cobalt mining camp is known to hug the lower Nipissing Diabase contact, which our drilling of the Angus Vein is confirming, and mineralization remains open particularly along trend. We are very encouraged to have identified numerous other mineralized veins in these drill holes, each of which has the potential for higher grades nearer to the diabase contact. The Campbell-Crawford prospect is showing classic signs of a significant Cobalt, Ontario-style silver/cobalt deposit and, with our updated understanding of the mineralization, we’re ready to test the size and grade of the area.”

David Stein, Kuya Silver’s President and CEO, stated: “In a very short period of time, Kuya Silver has made an exciting new discovery at the Campbell-Crawford prospect with very limited drilling to date. We are especially enthusiastic about the number of mineralized vein structures identified in this vein cluster given the presence of high-grade silver demonstrated by the Angus Vein. The recognition of multiple veins in close proximity and bonanza-style native silver mineralization are two important hallmarks of the larger historic producers in the Cobalt camp, and although we are in the early days of exploring this new area, Kuya Silver is off to a fantastic start.”

David Stein continued, “I am also very pleased to announce the promotion of David Lewis, P. Geo., to VP Exploration. His leadership on our geological team has been critical to Kuya Silver’s success over the past few years, and as our exploration programs expand in both Peru and Canada we entrust him to take a greater role in the Company’s growth.”

Angus Vein High-Grade Silver Mineralization Expanded

The Angus Vein has now been intersected in three oriented drill holes with drastically different silver/cobalt grades (Figure 1). The mineralized grades can be linked to the vertical distance from the Nipissing Diabase rock contact (Figure 2):

• 15,372 g/t silver, 0.08% cobalt over 3.34 m approximately 10 m below the diabase contact in Archean volcano-sedimentary rocks (23-SK-08 – 237 m),
• 2,424 g/t silver, 0.03% cobalt over 2.49 m approximately 30 m below the diabase contact in Archean volcano-sedimentary rocks (23-SK-13 – 258 m), and
• Low grade cobalt and arsenic identified by pXRF over 0.03 m (3 cm) carbonate vein approximately 115 m above the Nipissing Diabase contact and within the diabase (23-SK-07 – 108 m).

These three intersections match well with the mining camp model: mineralized vein structures are traditionally the most prolific close to the Nipissing Diabase contacts. Historically, the Archean volcano-sedimentary rocks are generally more prolific host rocks than the Nipissing Diabase, but extremely high silver grades are sometimes known just into the diabase host (for example Keeley-Frontier, Silver Cliff mines; Sergiades 1968) and this zone is untested at Campbell-Crawford.

The assay results also indicate metal zonation with high-grade silver zones transitioning into mixed silver-cobalt-nickel zones at depth or on vein margins (see January 9, 2023 news release). Very importantly, the NE-trending Angus Vein orientation and metal zonation suggests that these zones track along the lower diabase contact and may continue along trend (Figure 1, 2); other NE-trending veins, indicated in these drill results and especially veins drilled within the Nipissing Diabase, have the same mineralizing potential as the Angus Vein near the lower diabase contact, with associated significant to high grades of silver, cobalt and nickel.

Portable XRF measurements were captured using a handheld Thermo-Scientific Niton XL3t instrument, which was professionally calibrated in 2021 by Elemental Controls in Mississauga, Ontario.

David Lewis, M.Sc., P.Geo. Promoted to Vice President, Exploration (effective July 1, 2023)

Mr. Lewis is a structural and exploration geologist who joined Kuya Silver in 2021 to manage the Kerr Project and Silver Kings Joint Venture. He has 20 years’ experience in applied structural geology in consulting, mineral exploration, government, and academic roles throughout Canada and internationally, including in Arizona (USA), Greenland, and Mali (West Africa) on a variety of mineral deposit types. He was involved in defining structural controls on the Rosemont Skarn Deposit with Hudbay Minerals in 2018, the expansion and definition of the 1 km+ Tarabala gold trend with Compass Gold in 2020, the 71 m drilling intercept of the polymetallic Niish zone with Laurion Mineral Exploration in 2021, and he led the grassroots discovery of the silver-cobalt Angus Vein with Kuya Silver in 2023. In the Cobalt, Ontario mining camp, David worked as Senior Exploration Geologist with First Cobalt Corp. (2017-2019; now Electra Battery Materials Corp.) and now directs mineral exploration as the Technical Qualified Person at the Silver Kings Project on behalf of Kuya Silver Corp. In addition to his work with Kuya Silver, David teaches Structural Geology and Rock Mechanics at Fleming College, Lindsay, Ontario. David obtained his B.Sc. in Geological Sciences from the University of Saskatchewan and M.Sc. in Geology at Laurentian University.

Ongoing Work Plans

A surficial bedrock stripping program is commencing shortly in the Campbell-Crawford area to identify and trace surficial mineralized veins. Veins will be uncovered both along and across trend, testing for vein density, orientation and continuity and projected to depth, in preparation for a 2023 phase 2 drill campaign.

Quality Assurance and Quality Control

The drill core samples were logged and sampled with limestone blank material and standard reference material added in sample sequence and/or following visual identification of silver or cobalt mineralization. The samples were cut or split perpendicular to veining by core saw and were secured in labelled vinyl sample bags. Samples were shipped to AGAT Laboratories in Mississauga, Ontario, where they were weighed, crushed and pulverized. Silica wash material was used to clean the equipment between each pulverization for samples analyzed by Screened Metallics at SGS Labs.

At AGAT Labs, samples were digested by 4-acid and analyzed by ICP-OES (maximum undiluted detection limit of 500 g/t silver).

At SGS Labs, samples were processed by 500 g Screened Metallics. This method is suitable for coarse native metals (e.g. gold, silver, copper, palladium and platinum) with no upper detection limit. Samples were screened to 106 microns and fire assayed.
