Jul 14, 2020 (G Seim) - The Quyta prospect is hosted in a lenticulate mass of (quartz) feldspar porphyry about 2800 feet in length and up to 500 feet wide. The ends of the unit taper out into narrow 'dikes' The long axis of the unit is about 058 degrees. The porphyry intrudes mafic metavolcanics. Quartz+/-iron carbonate+/- tourmaline stringers to veins cut the porphyry. The veins strike 210 - 250 and dip north (avg. 60 degrees). Assays included with diamond drill logs in the assessment files indicate that the gold distribution is very nuggety. Three cuts from the one core sample assayed by 3 different labs. returned values of 0.01 ounce per ton gold, 1488 ppb gold and 14270 ppb over 5.0 feet.

| Vein | 3 | Quartz | Host |
Jul 14, 2020 (G Seim) - The porphyry consists of up to 30% anhedral to subhedral, white feldspar phenocrysts averaging 2-3 mm in cross-section. On the fresh surface the groundmass is aphanitic and pale green in colour. The weathered surface is pale green to brown.

Jul 14, 2020 (G Seim) - The following is from assessment file 52F/16NE-0023-A1: “The gold mineralization found in the Quyta prospect occurs in association with many vein, veinlet, and stringer penetrations into the feldspar porphyry. There appears to be 3 types of veining, i.e. quartz-carbonate, quartz-carbonate-tourmaline and quartz-tourmaline. It is not known if any of these is specifically favoured by the gold. Quartz-tourmaline appears to be the latest as seen through the cross-cutting relationships with the other two. The tourmaline has an amorphous sooty-black appearance ... the veining varies in width from 1 ft. down to 1/2 in. stringers and concentrations of these are seen to make up to 50% of the exposures at some points in the trenching. Dips vary from vertical to almost flat-lying. There is less than 1% fine pyrite present and it occurs mainly in the carbonitized porphyry flanking the veining.” From the 1980-82 drill program, hole Q-4 intersected low values over 90 ft. including 0.14 ounce per ton gold over 3.1 ft., Q-5 had a best assay of 0.66 ounce per ton gold over 5.0 ft., Q-6 low values over 120 ft. best 0.28 ounce per ton gold over 3.3 ft., Q-10 0.11 ounce per ton gold over 4.1 ft. Further assaying of this drill core revealed that highly erratic values could result from the same sample. One 5 ft. sample fire assayed 0.01 ounce per ton gold at Warnock Hersey, 1488 ppb at Bell White and 14,270 at Swastika. From the 1996 drill program: N-96-2 28.1 ft. grading 724 ppb Au, N96-3 2917 ppb Au over 2.0 ft. and 5215 ppb Au over 1.9 ft, N96-5 anomalous values from 327 ft. to 493 ft. including 8068 ppb over 5 ft., 1505 ppb Au over 10.0 ft and 1897 ppb Au over 1.1ft.
Jul 14, 2020 (Therese Pettigrew) - A wide porphyry dike has been traced for a distance of 3,000 feet in a northeasterly direction across the central part of the property... It is elliptical-shaped and is about 400 feet in width at the widest part. Where exposed by cross-trenches, the dike is a dark-green to grey porphyry of intermediate to basic composition with numerous white quarter-inch albite phenocrysts. A series of diagonal quartz tension-fractures from 1 to 3 inches in width are exposed in the trenching. Their predominant strike is N30E, and they dip at 45W. They are spaced 4 or 4 feet apart. Visible gold was noted in one of the fractures associated with sparse cubic pyrite mineralization. Sericitic alteration extends out from the walls for several inches. The fractures appear to be more plentiful towards the south side of the dike at the contact with amygdaloid andesite. There is strong evidence of shearing in the andesite in a northeasterly direction (Chisholm, 1951). The best grab sample collected by Tamaka in 2012 returned 0.287 g/t Au (Assessment report 20000007949).
Jul 14, 2020 (G Seim) - Weak to strong disseminated iron carbonate alteration is ubiquitous throughout the porphyry. Sericite is present in zones of shearing.
