The Doc occurrence is located over 2 kilometres west of the South Unuk River, opposite the mouth of Divelbliss Creek.

The occurrence is hosted by folded and metamorphosed Upper Triasssic Stuhini Group andesitic tuffs with interbedded siltstone, wacke and marble that have been intruded by irregular dioritic dikes or sills and small monzodiorite plugs of Middle Jurassic age.

Several mineralized veins, composed of milky white quartz, occur in a shear zone that cuts the rocks. These veins contain from 5 to 10 per cent sulphides with associated precious metals. Three different types of mineralization occur:

1) quartz veining with specularite and gold

2) quartz veining with galena, pyrite and gold

3) quartz veining with chalcopyrite and pyrite containing no precious metals.

The main vein structure (Q17/Q22) is about 2 metres wide and has been traced for 270 metres. The vein strikes at about 110 degrees and has a vertical to steep north dip. The main veins (Q17, Q22) are massive white quartz with sparse sulphide mineralization (5 to 10 per cent) consisting of galena. pyrite. chalcopyrite and sphalerite with associated specular hematite and magnetite. Precious metal values are mostly confined to the sheared edges of veins and immediately adjacent wall rock. Shear zones with very little quartz may also return good values.

Sampling in 1985 revealed that 170 metres of vein structure averaged 15.43 grams per tonne gold and 59.66 grams per tonne silver across an average width of 2.3 metres (Assessment Report 15615).

The veins are different from any others seen in the Sulphurets or Unuk map areas. They have very restricted wallrock alteration aureoles, no apparent zoning, and appear to be limited to a few large fluid pathways. In this they display characteristics of mesothermal veins. Structural control of the vein sets has not been determined but may be due to fractures related to folds in the host rocks (Fieldwork 1988).

A number of other veins—referred to as the TS, JT, Q28 and Q25 veins—have been identified in the area of the Q17/Q22 veins.

The TS vein is located approximately 200 metres north and downslope of the Q17/Q22 veins and approximately 100 metres west of the Doc portal. The TS vein comprises a 0.40- to 0.80-metre-wide quartz vein hosting galena, pyrite and trace magnetite. The vein trends 108 degrees, dips 62 degrees north and has been traced for approximately 25 metres down dip. Historical trenching on the vein is reported to have yielded up to 11.20 grams per tonne gold and 30.2 grams per tonne silver over 0.80 metres, whereas grab samples are reported to have yielded up to 69.02 grams per tonne gold and 541.2 grams per tonne silver (Mitchell, A.J., Prowse, N.D. [2020-06-08]: NI 43-101 Technical Report on the Doc Property).

The JT and Q28 veins are located approximately 120 to 200 metres south-southwest and upslope of the Q17/Q22 veins. The Q28 vein comprises a 0.46- to 219-metre-wide (averaging 1.95 metres), yellow-stained and heavily sheared quartz vein hosting minor pyrite and lesser galena, specularite and magnetite. The vein has been traced along strike for approximately 95 metres. The JT vein is 1.0 to 2.0 metres wide and has been traced along strike for approximately 100 metres and to a depth of approximately 80 metres. Historical trenching on the Q28 vein is reported to have yielded up to 75.00 grams per tonne gold and 252.4 grams per tonne silver over 0.55 metre, whereas drilling on the JT vein is reported to have yielded 3.39 grams per tonne gold over 2.55 metres (Mitchell, A.J., Prowse, N.D. [2020-06-08]: NI 43-101 Technical Report on the Doc Property).

The Q25 vein is located approximately 500 metres west-southwest and upslope of the Q17/Q22 veins. The vein comprises a yellow-stained quartz vein, 0.85 to 1.95 metres wide and averaging 1.37 metres wide, with minor disseminated pyrite, up to 15 per cent galena and possible native gold. The vein has been traced along strike for approximately 115 metres. The vein is also on trend with the Q28 vein and may share the same mineralized structure. Historical trenching is reported to have yielded up to 69.60 grams per tonne gold and 278.8 grams per tonne silver over 1.49 metres of galena-bearing material, whereas a rock sample of barren quartz material yielded 25.82 grams per tonne gold and 15.19 grams per tonne silver (Mitchell, A.J., Prowse, N.D. [2020-06-08]: NI 43-101 Technical Report on the Doc Property).

Combined (proven, probable, possible) reserves in Q17 and six other veins are 426,337 tonnes grading 44.9 grams per tonne silver and 9.2 grams per tonne gold (Northern Miner - November 7, 1988).

Work History (from Assessment Report 26256 (reserves not NI-43-101 compliant))

In the 1880s gold mineralization was discovered in the area by prospectors exploring the Unuk River Valley via Alaska. The Globe claims, adjacent to the Doc, were staked in 1899; and two veins were explored by several trenches and four adits. A small stamp mill was erected, and 45 tons of high-grade ore were stockpiled, but no shipments were made.

In 1945. Leitch Gold Mines identified gold veins and optioned mineral claims covering the property, then known as the Gracey Group, to Halport Mines. In 1947, Halport discovered new veins by prospecting and trenching. In 1948, Halport drilled 19 holes on the 417 and Q22 veins. In 1949, ten holes were drilled on the Q25 vein.

In 1974. New Minex Resources acquired the claims, and channel sampled the Q17 and Q25 veins. Ground magnetic and VLF-EM surveys were completed in 1975.

In 1985, Silver Princess Resources optioned the property from Tom McQuillan and resampled old trenches on the Q17 and Q22 veins.

In 1986 Magna Ventures optioned the ground and conducted 1065 metres of diamond drilling in 13 holes, 33.5 metres of access tunneling on the 417 and 422 veins. and further staking and prospecting.

In 1987. Magna completed a total of 377 metres of underground development, 695 metres of underground drilling in 8 holes, prospecting (1647 samples), and collection of 269 samples from 48 trenches/adits. A total uncut, undiluted mineral inventory, including all categories of reserves of 425,892 tonnes grading 9.26 grams per tonne gold and 44.91 grams per tonne silver was reported for seven veins on the property, including the Globe North and South veins. Further details are provided in Assessment Report 26256.

In 1988, Echo Bay Mines Ltd entered into a joint venture agreement with Magna and Silver Princess to proceed with further development and reserve definition on the Q17 and Q22 veins, and to establish a multi-million-ounce gold resource. Echo Bay completed 3074 metres of diamond drilling in 32 holes; 239 metres of underground development, and underground mapping and sampling. Including all categories of reserves, total mineral inventories were established as 91,490 tonnes grading 8.85 grams per tonne gold for the Q17 and Q22 veins using a 3.43 grams per tonne ton cut-off. Further details are provided in Assessment Report 26256.

In 1996, the property was allowed to lapse as a result of a dispute between the previous claim owners and was immediately staked by the Hunter Exploration Group. In October I999 a prospecting program was conducted by Hunter Exploration on the property resulting in the discovery of BGS showing.

In 2013, UTM Exploration Services Ltd conducted an exploration program on the Doc property on behalf of John Bot. Proposed work for the 3 days was to identify the main vein systems and continue along trend, as well as on trend parallel to the main veins in hopes of locating new veins. More exploratory work was to focus on the northeast wooded sections, and the southwest. The adit, a couple of trenches, and five (5) exposures of quartz veins, as well as potential new locally mineralized zones were found. Eighteen rock samples were collected on the Doc property with 9 of those samples being collected in the BGS (104B 615)/Quinn-Eskay (104B 471) area about 1 kilometre or more south of the Doc occurrence where a new mineralized vein set was discovered. See the BGS showing for details of the new vein set.

During the 2015 field season, John Bot contracted CJL Enterprises Ltd. of Smithers, B.C. to conduct a limited prospecting and sampling program on the DOC Property. The 2015 exploration program focused on the old hand trenches and veins located on the claim block 1,036,952 which is the center of the claim block. Twenty-six rock samples were collected and assayed for gold and silver. The quartz veins sampled ranged from heavily mineralized to barren bull quartz with the highest grade samples assaying 103 grams per tonne gold with 515 grams per tonne silver (sample 1151221), 58.6 grams per tonne gold with 343 grams per tonne silver (sample 1151217), and 41 grams per tonne gold with 189 grams per tonne silver (sample 1151219) all associated with galena (Assessment Report 35635).

In 2018, Tudor Gold Corp. completed a reconnaissance rock sampling program a short distance west of the BGS (MINFILE 104B 615) zone.

In 2019, Hanstone Capital Corp. completed a program of prospecting, geological reconnaissance, rock sampling and 30.5 line-kilometres of ground magnetometer surveys on the area as the Doc property.
