Assays and Quality Assurance/Quality Control

by:JPSK     2020-04-25
To ensure reliable sample results, Wildcat has a rigorous QA/QC program in place that monitors the chain-of-custody of samples and includes the insertion of blanks, duplicates, and certified reference standards in each batch of samples. Core is photographed and split in half with one-half retained in a secured facility for verification purposes. Sample preparation (crushing and pulverizing) is performed at Skyline Laboratories, an ISO/IEC accredited lab located in Tucson, Arizona. Skyline Laboratories prepares two pulps of all samples and completes analysis of one pulp sample by ICP for Cu% (copper), Pb% (lead), Zn% (zinc) and Mn% (manganese). The second pulp is shipped to Inspectorate Labs, an ISO: 9001-2008 accredited laboratory in Reno, Nevada, where the duplicate pulp is analyzed for Au (gold) and Ag (silver). Silver values are determined by fire assay (1 AT) with an AA finish. For all samples that assay greater than 200 ppm Ag, the sample is re-run using fire assay (1 AT) with a gravimetric finish. Step-out hole HDS-111B is located on the western edge of the current resource and was successful in extending the known mineralization to the west. Hole HDS-111B intersected 19.8 metres of 282.8 g/t silver, 7.99% manganese, 1.64% zinc, 2.37% lead, and 0.17% copper within an interval of 32 metres averaging 186.2 g/t silver, 6.29% manganese, 1.29% zinc, 1.5% lead and 0.11% copper. Of particular note, step-out hole HDS-119 was drilled to the northeast of the current Hermosa deposit suggesting that silver mineralization continues across the northwest-southeast American Fault. An upper zone encountered 6.1 metres averaging 377.2 g/t silver, 0.02% manganese, 0.02% zinc, 0.64% lead and 0.03% copper within an interval of 12.2 metres of 220.5 g/t silver, 0.10% manganese, 0.01% zinc, 0.61% lead, and 0.03% copper. In the lower mineral horizon, this hole encountered 9.1 metres of 305.5 g/t silver in addition to 21.12% manganese, 1.28% zinc, 2.39% lead, and 0.36% copper. This intersection was within a broader interval of 24.3 metres which averaged 139.9 g/t silver, 15.30% manganese, 5.75% zinc, 1.43% lead and 0.19% copper. Hole HDS-122 is located in the southern extent of the current resource and confirms continuity between widely spaced holes in the southern portion of the deposit. Hole HDS-122 encountered 18.4 metres of 218.4 g/t silver, 8.64% manganese, 1.21% zinc, 0.70% lead and 0.05% copper. The Company intends to continue to aggressively drill to the end of the year as mineralization remains open in all directions. Exploration efforts will primarily focus on step-out drilling with the objective of significantly expanding the current resource. Wildcat now has four drills operating on the property (two core and two reverse circulation). Qualified Person The results of Wildcat's drilling results have been reviewed, verified and compiled by Don Taylor, MSc., PG, vice president of exploration for Wildcat Silver, a qualified person as defined by National Instrument 43-101 (NI 43-101). Mr. Taylor has more than 25 years of mineral exploration and mining experience, and is a Licensed Professional Geologist in several US states.
