The Mot 1 prospect is located approximately 3.5 kilometres northwest of Motase Lake.

The prospect comprises five zones which are, from northwest to southeast, the Huestis, Moran, Goudridge, Solomon, and Charles (Assessment Report 20505). Of these five zones, the Huestis and the Goudridge zones are considered to be the most important.

The zones occur along the eastern margin of the Bowser basin. The area is underlain by Upper Jurassic to Lower Cretaceous sediments of the Bowser Lake Group. Further to the east, volcanics of the Upper Triassic Takla Group and the Middle to Upper Jurassic Hazelton Group dominate. The rocks are intruded by feldspar porphyry and granodiorite dikes and sills. These intrusions are related to either the Eocene Kastberg Intrusions or the Cretaceous Bulkley Intrusions. The Bulkley Intrusions occur further to the south.

All of the zones lie within a west-northwest trending gossan, approximately 3 kilometres long. This zone consists of fine-grained argillite, greywacke and coarse pebble conglomerate, which strike northwest and dip southwest. Thin quartz veins, commonly striking about 10 degrees with vertical to steep east dips, cut both the feldspar porphyry and the sediments. The quartz veins contain white quartz, a few vugs and a small amount of disseminated sulphides. The sulphides are pyrite, sphalerite, chalcopyrite, galena, molybdenite, pyrrhotite, arsenopyrite, and scheelite (Assessment Report 10432).

A 1.5-metre diamond drill interval from the Huestis zone contained 20.6 grams per tonne gold and 322.3 grams per tonne silver (Assessment Report 20505). A 3-metre chip sample from the Goudridge zone assayed 11.9 grams per tonne gold and 16.1 grams per tonne silver (Assessment Report 20505).

WORK HISTORY

The area of the Mot prospects (094D 001 and 042) was first staked by H.H. (Spud) Huestis (one of the founders of Bethlehem Copper Corporation) in 1948. Mr. Huestis prospected the claims and found several gold-bearing quartz veins, one of which occurs on FC #13, the Huestis zone.

Subsequent to discovery, three areas with gold showings were identified on the property and are named the 'Huestis', 'Goudridge', and 'Moran' with the majority of the work having been carried out on the Huestis zone which consisted of quartz veins, altered sediments, and feldspar porphyry intrusions.

In 1962, the F.C. group of nineteen claims, held by Huestis Mining Corporation Ltd, were optioned by Noranda who then completed EM and magnetic surveys and drilled 5 short EX holes, totalling 92 metres. Noranda’s best intersection was of 10.97 grams per tonne gold over 9.14 metres (estimated to be 6.1 metres apparent true width) (as reported in Assessment Report 17339 (page 1)). Noranda dropped the option in late 1962 and eventually all claims lapsed except FC #13 and #15.

As reported in Assessment Report 17339 (by Prolific Resources), in 1973, Canadian Superior Exploration Limited carried out geological mapping, prospecting, and stream geochemical sampling in an area immediately north of (what would later be) the MOT claim of Amoco Canada Petroleum Company Ltd. Canadian Superior encountered weak molybdenum, copper, and gold values in float boulders of hornfelsed sediments. No gold analyses were carried out on silt samples. The following year (1974), Ducanex Resources carried out trenching, geological mapping, and soil geochemical sampling for Canadian Superior in the same claim area.

In 1980, Amoco Canada Petroleum Company Ltd staked the MOT 1 claim (20 units) and collected 245 soil samples, resulting in several areas anomalous in Cu, Mo, Au, and Ag (Assessment Report 8844). The MOT 1 covered the Huestis, Goudridge and Moran zones. In 1981, based on the results of a regional stream geochemical sampling program, Amoco Canada staked claims over the Mot area entirely surrounding Cominco's FC #13 and #15 claims. They followed up with soil geochemical sampling, rock sampling, geological mapping, and diamond drilling. Amoco defined a sizeable geochemical anomaly (copper, molybdenum, gold, silver, and tungsten) covering a northwest trending area about 2500 metres by 750 metres which included the Huestis zone. A gold anomaly outlined an irregular area for values of 1000 parts per billion that measured 450 metres by 200 metres. Gold values of 400 parts per billion extended over an area 800 metres and averaged 350 metres in width. 916 metres of drilling was completed in four holes, targeting potential porphyry style mineralization to the east of the Huestis zone, with negative results. The claims were once again allowed to lapse in 1985.

In 1983, on the FC #13 and #15 and MOT 1 claim, Cominco carried out detailed mapping and re-sampling of the old Noranda core and sampled outcrop a few metres above Noranda’s drill holes 2 and 2A (Assessment Reports 11630 and 11631). Drill hole sampling revealed high gold and silver values are associated with intercepts of quartz veins. The best value came from hole N-1 where 11.5 metres graded 11.3 grams per tonne gold (Assessment Report 11630). The Goudridge zone was reported by Cominco to consist of quartz within an alteration envelope at the contact between feldspar porphyry and sedimentary rocks. Here, a 3-metre chip sample yielded 11.86 grams per tonne gold, 16.11 grams per tonne silver, 0.017 per cent molybdenum, and negligible copper, lead, and zinc (Assessment report 11631). Cominco also named the Moran zone, which occurs near the ridge top to the southeast of the Huestis area. A 0.1 metre quartz vein sample graded 26.4 grams per tonne gold, 96.1 grams per tonne silver, 1.4 per cent lead, 0.04 per cent zinc and 0.08 per cent copper (Assessment report 11631). Cominco allowed all of the claims to lapse with the exception of the two core claims covering the Huestis zone.

In 1986, the MOT and MOT 2 claims were staked by B. H. Kahlert, who carried out limited rock sampling. The MOT and MOT 2 claims were optioned from Kahlert by Prolific Resources Ltd., and along with the purchase of the Cominco claims, formed the Motase Lake property. In 1987, Prolific Petroleum Ltd. conducted an exploration program on the MOT 2 claim, just north of the MOT claim where the historic mineralization of the Mot 1 prospect (094D 001) (Huestis zone) is located. Work completed on the MOT 2 claim during June 1987 consisted of detailed prospecting and geological mapping. Thirty-six rock samples were taken by prospectors. Rock samples consisted primarily of quartz vein material. Results ranged up to 4.74 grams per tonne gold and up to 52.0 grams per tonne silver (Assessment Report 16305).

From July to September 1987, Prolific Resources Limited completed significant work on the MOT claim area including 976 metres of drilling in 10 holes on the Huestis zone together with extensive prospecting and surface geochemical surveys (Assessment Report 17339). The best drill intersection from this program was 5.2 metres grading 8.9 grams per tonne gold and 17.83 grams per tonne silver (Assessment Report 17339). Prolific collected 117 rock samples during the program. The eastern half of the Huestis zone was extensively prospected. Chip sampling across a quartz zone returned 8.91 grams per tonne gold over 4 metres (Assessment Report 17339). Grab samples grading up to 68.5 grams per tonne gold were obtained from surface sampling on the Huestis zone. The Goudridge zone was extended to the north and northwest. Rock samples grading up to 14.6 grams per tonne gold were acquired from the Goudridge zone and values up to 4.8 grams per tonne gold were obtained from the Moran zone (Assessment Report 17339).

In 1987, investigation by Prolific Resources Limited of the 1981 Amoco soil-grid anomalies defined the "North" (Anomaly 6), thought to be the Mot 2 showing (094D 042). As well as the North (Anomaly 6) zone, the Solomon, and Charles zones were defined and also described as gold-bearing quartz vein systems (Assessment Report 17339, Figures 3 and 5 and Map 1).

In August 1988, a one-day exploration program consisting of prospecting and rock geochemical sampling was undertaken by Taiga Consultants Ltd. A total of 14 rock samples were acquired on the MOT 1 Mineral Claim during the evaluation. The MOT 1 claim, held by Taiga, covered the original Mot 1 prospect (094D 001) zones including the Huestis zone. Of the 14 samples collected, 8 samples were significant, ranging between 5.93 grams per tonne gold and 24.79 grams per tonne gold (Assessment Report 18361, 18390).

In 1990,Taiga Consultants Ltd. was contracted by Leeward Capital Corp. to undertake a geochemical report on the Mot 1 mineral claim. Selected pulps from the 1987 and 1988, programs were analyzed for copper, lead, and zinc (Assessment Report 19610). In September a one-day exploration program, directed at investigating the Goudridge Zone on the Mot 1 prospect (094D 001) was undertaken. Sampling of this area was reported to have revealed significant gold mineralization in a quartz vein system. Fourteen rock samples were collected. The zone was reported to be up to 8 metres wide, consisting of a number of parallel quartz veins. The strike of the zone was 260 degrees, dipping 50 degrees south, and contains two quartz-rich sections 3.8 metres and 1.0 metre wide. Sampling yielded 0.89 gram per tonne gold over 3.0 metres and 22.01 grams per tonne gold over 1 metre (Assessment Report 20505).

In 1995 Skeena resources completed 5.1 kilometres of grid emplacement, followed by magnetometer and VLF-EM surveys, and the collection of 191 soil samples on the FC-15 claim, the Solomon Zone on the MOT 1 claim (Assessment Report 24266). Significant gold-in-soil anomalies were found on both FC-15 and Solomon grids.

In 1998, Electrum Resource Corp. commissioned a satellite image interpretation of the property from Earth Science Surveys Inc. in order to identify larger scale structures with which gold mineralization could be associated (Assessment Report 26201).

In 2007, Electrum Resources conducted a program of prospecting collecting 45 rock, 25 stream and 2 soil samples on the MOT North group; 11 rock and 5 stream samples on the MOT South group; and 15 stream samples from the MOT West group. On the MOT North group, consisting of tenures 517965 and 550767, there are at least two occurrences of polymetallic mineralization, one is mineralized float at 616830E, 6216550N and the other, on tenure 517965, is thought to be the MOT 2 showing (MINFILE 094D 042) located at 616280E, 6217230N. This is reported to be located within an area designated the “North Zone” on a map by Davis and Jamieson (1988a) (Assessment Report 18361). One 3-centimetre vein graded 35.8 grams per tonne silver, 0.04 per cent copper, 0.88 per cent lead, 0.18 per cent zinc, and 60 parts per billion gold (Assessment Report 29796). Veins were reported to be up to 20 centimetres thick. MOT West manifested no signs of mineralization. MOT South was only partially prospected.

In 2012, Copper Mountain Mining Corporation optioned seven properties in the Bear Lake area from Electrum Resource Corporation including the Mot Group (Assessment Report 33596). Three traverses were run on the Mot property with the intent to sample the south gossan area, to collect rock chip samples from the Huestis zone and to cover as much property area and see as many zones as possible. The work was undertaken with the purpose of evaluating the area for deep seated porphyry copper-gold deposits or in the case of the MOT area for a bulk tonnage style gold deposit.

In 2013, the objective of Copper Mountain for the MOT property was to examine the northern parts of the property that had not been examined in 2012 (Assessment Report 34670). A total of 41 stream sediment samples (including 7 moss mats), 31 soil or talus fines samples and 7 rock samples were collected.
