Includes High Grade Sample 4,311g Ag Eq/t (3,994g Ag/t, 3.28g Au/t, 2.01% Pb)
Ottawa, Ontario--(Newsfile Corp. - March 21, 2022) - Mayo Lake Minerals Inc. ('Mayo or the Company') is pleased to announce the results of its summer 2021 prospecting and soil sampling program in the Carlin West area of its Carlin Roop silver project bordering on the southern portion of Metallic Minerals' Keno property, Yukon Territory. The results were first released on SEDAR (please see: Mayo Lake Minerals Inc., Technical report, December 15, 2021).
Thirteen (13) grab samples1 were collected during prospecting at Carlin West. The silver content of seven (7) rock samples ranged from 72g Ag Eq/t to 4,311g Ag Eq/t. The full results are listed in Schedule 1 hereunder with their locations on Figure 1.
The grab sample yielding 4,311Ag Eq/t was located at the northern end of a very strong Ag in soil anomaly (Priority Anomaly2) on Figure 1 at Carlin West. It was part of the Priority Anomaly where the anomaly showed its highest values. Another rock sample that yielded 737g Ag Eq/t was located along a more subtle secondary Ag in soil anomaly. This latter anomaly was at an obtuse angle to the Priority Anomaly. Four grab samples, yielding 562, 199, 197 and 72g Ag Eq/t, were located along an Ag in soil anomaly that was defined during the 2021 detailed soil grid sampling.
Soil sampling at Carlin West has now delineated four (4) Ag in soil anomalies beyond the Priority Anomaly, all of which provide favourable drill targets for high-grade Keno Hill Silver Mineralization. These targets will be fully tested during Mayo's summer 2022 diamond drilling campaign.
Dr. Vern Rampton, CEO and President of Mayo, commented, "Last summer's prospecting confirmed that the zones (linear Ag in soil anomalies) defined by the soil sampling could well be indicative of mineralized bedrock with grades equivalent to those at the Keno Hill mines." He further stated, "Our primary objective this year is to diamond drill a minimum of 1500m, fully testing the soil anomalies defined to date, including the Priority Anomaly. The Priority Anomaly was only tested by scout diamond drill holes with limited mobility to position on advantageous collar locations in 2020 and 2021. In 2022, we will have greater on site mobility for properly positioning collar locations. In addition, the base of the ridge is now accessible by secondary roads connecting with the territorial road network at Keno. Another objective at Carlin West is to delineate more drill targets through soil sampling and IP-Resistivity."
In July 2021, in addition to the 13 rocks, a total of 131 soil samples from the C-horizon were collected on a 30m square grid at Carlin West. They were forwarded to the Bureau Veritas Commodities Canada Ltd (BMV) laboratory where 15g of each sample was analyzed by Aqua regia digestion, ICP-MS analysis (BMV AQ201) for 36 elements (Ag, Al, As, Au, B, Ba, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, Hg, K, La, Mg, Mn, Mo, Na, Ni, P, Pb, S, Sb, Sc, Se, Sr, Te, Th, Ti, Tl, U, V, W, Zn). Those rocks exceeding the upper limits of detection for AQ201 were analyzed by Aqua Regia ICP-ES (BMV AQ370) and the one sample with Ag exceeding the upper limits of detection was analyzed by fire assay (BMV AQ370). BMV's management system meets the requirements of ISO/IEC 17025 and ISO 9001 with their oversights and processes. Appropriate duplicates, standards and blanks are inserted in each analytical run. Mayo has independently inserted sample duplicates at a rate of one per thirty-three collected samples.

About Keno Hill Silver District (KHSD): The Keno Hill Camp is a belt, 21 km long by 2 - 6.5 km wide that contains numerous silver deposits, two with probable reserves of 37.2 million oz Ag at 804g Ag/t; 14,000 oz Au at 0.3g Au/t; 84 million lbs Pb at 2.6% Pb; and 122 million lbs Zn at 3.8% Zn (74 million oz Ag Measured and Indicated and 25 million oz Ag Inferred). These reserves are currently being mined by Alexco Resources.
The mines at Keno Hill in the Central and Western Sector of the KHSD are all characterized by high-grade Keno Hill Style Mineralization (KHSM), silver-lead-zinc vein deposits with notably high-grade silver contents, commonly in excess of 1000 grams (approximately 32 ounces ) of silver. Over 214 million ounces of silver have been mined to date from the camp. The Elsa Mine, the second largest at Keno, produced 30 million ounces from 150 metres of vein strike length.
Mayo's Carlin Roop property and Metallic Minerals' Keno property cover most of the terrain within the Eastern Sector of the KHSD. This sector has been subjected to modern exploration and drilling only over the last two years. Both Metallic Minerals and Mayo have successfully defined areas showing high-grade KHSM. The Eastern Sector of the KHSD is marked by similar structural setting and history, geologic units, alteration and mineralization as found in mines in the Central and Western Sectors of the KHSD.
About Mayo Lake Minerals Inc.: Mayo Lake Minerals is focused on the on the rapid development of precious metal projects in the Mayo Mining District of the Yukon Territory. It presently has, subject to certain net smelter royalties, a 100% interest in 1139 claims, totalling 232 sq.km in area. It's five claim groups all lie within the Tombstone Plutonic Belt of the Tintina Gold Province in the Yukon Territory. Four claim groups are focused on gold and one on silver. It currently has 90.8M shares outstanding.
