The Scottie Gold mine is situated near the northwestern tip of Summit Lake, south of the Berendon Glacier. The property was staked in 1930 and extensive diamond drilling and limited underground development was carried out subsequently until 1949. Production began in 1981 and continued until 1984.

The Scottie Gold deposit is hosted by steeply east dipping volcaniclastic rocks of the Lower-Middle Jurassic Unuk River Formation of the Hazelton Group. These consist of green andesitic breccia and conglomerate with thin intercalated volcanic sandstones and tuffaceous bands. The strata are cut by mineralized veins, faults and lamprophyre, microdiorite and porphyry dikes. Several alteration assemblages are developed in the area.

The Lower Jurassic Summit Lake stock, which comprises hornblende quartz monzonite and/or hornblende granodiorite, lies to the northwest. The intrusives are locally sheared and chloritized, in particular, where it is transected by the Morris Summit fault. A wide but variable aureole around the intrusive is present with the inner envelope being a pervasively silicified contact zone with fine disseminated pyrrhotite grading outwards to altered volcanic breccias.

Structurally, the property is dominated by a set of north striking faults, the most dominant of which is the west dipping Morris Summit fault. East of the Morris Summit fault zone the area is dominated by north striking faults and to the west, by east striking faults and lineations. The eastern area is cut by a suite of north striking microdiorite dikes. The mineralized veins are components of secondary shears of the Morris Summit fault.

Alteration to the north of the property is characterized by the development of fine-grained pyrrhotite or pyrite in the volcanic host. To the south, the alteration zone has a gradational contact with less altered Hazelton rocks. Overprinting of the regional assemblage by the Summit Lake stock occurs. To the west of the Morris Summit fault, the Hazelton Group is metamorphosed to greenschist facies and locally altered to a grey to green fine- grained quartz-chlorite-pyrrhotite-pyrite assemblage.

The Scottie deposit consists of several mineralized quartz-carbonate veins, each forming an en echelon or ladder vein pattern across a 120-metre width and up to a 300 metre depth. The veins, which are up to 7 metres wide and average 2 metres wide, show variable sulphide content and occur north of Main Creek. Referred to as No. 1, 2 and 3 veins, the steep, north dipping mineralized veins strike west and converge with the northwest striking Main zone. Elsewhere in the area, (south of Main Creek) the veins are erratic in strike length and width. The overall mineralized area measures about 400 by 250 by 300 metres.

The veins contain lenses of massive sulphide, consisting largely of pyrrhotite and pyrite, with lesser sphalerite, chalcopyrite, galena, arsenopyrite, tetrahedrite and gold. The veins occur along near vertical fracture systems and are bordered by siliceous replacement zones with poorly defined walls.

About 250 metres north of the Main zone is a 15-metre-wide quartz vein. The vein, which strikes 160 degrees and dips 60 degrees west, contains a 5-centimetre-wide stringer of massive galena, and minor pyrite and tetrahedrite.

Other zones of mineralization in the area of the main Scottie Gold occurrence include the Lone Wolf and 6 Ounce zones. The Lone Wolf zone is exposed approximately 150 metres due west of the M zone and consists of sheeted quartz-carbonate-sulphide veins. The 6 Ounce zone is location approximately 600 metres south of the Scottie Gold occurrence and comprises a sheeted set of narrow quartz-carbonate-pyrite shear vines.

Work History

In 1928, a series of gold bearing veins were located at Summit Lake. The original showings were staked in 1930 by Ted Morris and associates of Stewart as the Salmon Gold group of 26 claims. Some of the claims were reportedly a restaking of the old Columbia group, of which no record has been found. Crown-grants were issued for 15 claims, the Gold No, 11 (Lot 6270), Summit Lake Nos. 1-8 (Lots 6296-6301, 6405, 6406), and Prince Nos. 1, 2, 4-6, and Prince Fr. (Lots 64074412).

In September 1931 Premier Gold Mining Company, Limited optioned the property. Work by the company included open cutting, and 219 metres of diamond drilling in 12 holes; the option was dropped late in the year. Salmon Gold Mines, Limited was incorporated in June 1933 to acquire the property. The Consolidated Mining and Smelting Company of Canada Limited acquired an option on the property in 1934 and during that and the following year carried out diamond drilling in several deep holes, one of which intersected good gold mineralization. The 3600-level adit (upper adit), begun in 1936 to investigate the values found in drilling, was extended to a total of about 457 metres of drifts and crosscuts by 1939. The Consolidated Mining & Smelting Company dropped the option at the end of July 1939.

The owners transferred the property to a new company Morris Summit Gold Mines, Limited which they had incorporated in December 1945. Diamond drilling in 1945 and 1946 totalled 1786 metres. During 1946 the lower adit (3,000 level) was begun at the 891 metre elevation, some 183 metres below the upper adit. The adit was driven westerly and southwesterly for 731 metres to the mineralized zone. Development work on the mineralized zone in 1947 and 1948 included about 396 metres of drifting, 109 metres off crosscutting, and 58 metres of raising. About 1450 tonnes of ore-grade material was broken in drifting on the veins. Underground diamond drilling during 1947 and 1948 totalled 3195 metres. Work on the property ceased in 1949. Reserves in the A and B veins, over widths of 2 metres and 0.74 metre respectively, were estimated at 107,750 tonnes averaging 31.89 grams per tonne gold (uncut), or 7.09 grams per tonne(cut) (E.E. Harris, Oct. 1948 Rept. for Morris Summit Gold Mines)

Scottie Gold Mines formed in 1978 to develop the Summit Lake Property. In 1980, the decision was made to place the property into production and from 1981 to 1984 inclusive the mine produced 2,984,054 grams of gold and 1,625,145 grams of silver from 160,264 tonnes of mined ore. Royal Scot Resources and Tenajon Resources Corp completed limited exploration at the Summit Lake Gold Mine from 1985 to 2003, including the C, Bend and other zones.

Underground mineable reserves at Scottie Gold are 28,992 tonnes grading 18.51 grams per tonne gold (D. Alldrick, personal communication, 1992).

In 2004, Tenajon Resources Corporation reactivated exploration at its Summit Lake (Scottie) underground gold mine. Fourteen holes totaling 1280 metres were drilled from the mine workings to confirm historic drill intersections and to extend the L, M and N zones. Intercepts range from 2 to 40 grams per tonne gold over apparent widths of 0.3 to 4 meters (Exploration and Mining in British Columbia 2004, page 31).

In 2004, the Summit Extended claims of Seeker Resources and Trans Pacific Mining envelop the Scottie/Summit Lake Crown Grants covering the much of the ground of Royal, Prince, Scot Summit Lake and Tide Claims formerly owned and operated by Royal Scot Resources Ltd (during the 1980s and into the early 1990s (Assessment Reports 16768, 20987, 23874, 25225). Work in 2004 provides location and assessment of mineral occurrences, geochemical and geophysical anomalies in the vicinity west of Summit Lake and in the area of Scottie Gold (Assessment Report 27502).

In November 2004, Tenajon released results from its 14-hole underground drill progam. Highlights included 4.36 metres grading 38.98 grams per tonne gold and 4.2 metres grading 32.95 grams per tonne gold (Tenajon Resources Corp., News Release, November 22, 2004).

In 2004 and 2005, Tenajon Resources Corp. began a 1,200-metre underground drilling program at the Summit Lake project (Scottie past producing mine). In 2005, Tenajon reported a drillcore intersection that assayed as high as 121.29 grams per tonne gold in a 1.52-metre intersection Canadian Mining Journal, November 16, 2005). The Summit Lake project is the site of the old Scottie gold mine, located 50 kilometres north of Stewart. When the former mine was shut down, employees made a non-NI 43-101 compliant estimate that there remained 120,000 tonnes of ore grading 19.13 grams per tonne gold in the mine (Canadian Mining Journal, November 16, 2005).

In 2005, Tenajon Resources Corporation drilled nineteen underground holes testing the M zone (east and west of previous mining) and the N and L zones. Intercepts ranged between 3.5 grams per tonne gold and 24.6 grams per tonne gold over widths of 0.5 to 8 metres (Exploration and Mining in BC 2005, page 33). Surface drilling (16 holes, 639 metres) tested the Bend (MINFILE 104B 132), Blueberry (MINFILE 104B 133) and Road veins, and returned intercepts of 10 to 20 grams per tonne gold over true widths of 1 to 2 metres (Exploration and Mining in BC 2005, page 33).

On October 1, 2011, Rotation Minerals Ltd announced that it had entered into an agreement to purchase an 80 per cent interest in the former Scottie Gold mine. Indicated resource for the L, M, N and O veins of 20,000 tonnes grading, 9.91 grams per tonne gold, 4.32 grams per tonne silver; an Inferred resource for the L, M, N and O veins of 203,000 tonnes grading 8.40 grams per tonne gold and 4.25 grams per tonne silver (Rotation Minerals Ltd website). This resource is not considered 43-101 compliant by Rotation Minerals.

In 2012, Rotation completed a program of preliminary evaluation which included sampling several known vein structures in addition to several newly located gold bearing structures (Press Release, December 4,2012, Rotation Minerals Ltd). The Company sampled the Bend (104B 132), Road (104B 133), Blueberry (104B 133), the “M” vein underground and 3 newly located veins.

In 2016, a total of 2648.78 meters of diamond drilling was completed in 21 holes from 5 different pads. A total of 1935.36 metres of drilling was completed on the Sum 1 claim. Diamond drilling was carried out on an area called the “C” and “D” zones in previous work. This area is 2 kilometres northeast of the mine workings and is readily accessible through the nearby mine access roads. In 2016, drilling by Rotation intersected up to 1.13 metres of 31.54 grams per tonne gold in DDH-SG-4. Drilling was primarily focused on the intersection of the projected C and D veins (Rotation Minerals Ltd., News Release, October 18, 2016).

In 2016, Rotation Minerals Ltd. discovered a new wide zone of altered rocks containing veins and stockworks of sulphides on the Scottie gold property. The zone is in an overburden covered area and was exposed by drill pad building activities. It consists of massive pyrrhotite veins and stringers containing minor chalcopyrite cut by later narrow pyrite veins. Molybdenum and visible gold have been noted in one area of an exposed massive pyrrhotite vein. The overall width of this new alteration zone appears to be seven to eight metres. Drilling from this location was initially intended to intersect the C vein, A total of 21 grab samples were collected from the main zone area over 15 metres and assays ranged from 1.4 grams per tonne gold to the high of 447.95 grams per tonne gold (Rotation Minerals Ltd., News Release, September 14, 2016). These grab samples are not representative of the entire zone area.

In 2016, Triangle Exploration Limited (optionee from Eilat Explorations) completed a 566-kilometre airborne magnetic and radiometric survey which extends east, north and south from the eastern shore of Summit Lake to the eastern boundary of Eilat Exploration's 2012 airborne survey. The 2016 survey is a continuation of the airborne survey flown for Eilat Exploration in 2012 (Assessment Report 33511). Data collected from the 2016 Summit Lake survey block were merged with data collected in 2012 (Assessment Report 36318). The combined data covers 10 mineral occurrences documented in MINFILE: Scottie Gold (104B 034), St. Eugene (104B 036), Scottie North (104B 074), Blueberry (104B 133), Hicks (104B 139), Summit 5 (104B 436), Summit Gossan (104B 648), Summit Nunatak (104B 649), Glacier Edge (104B 650). Scottie Gold mine and the outlying areas held by Rotation Minerals Ltd are covered by the combined 2012 and 2016 airborne survey.

During 2018 through 2020, Scottie Resources Corp. completed programs of rock and auger (tailings) sampling, airborne and ground geophysical surveys and diamond drilling on the Scottie Gold property.

In 2019, drilling on the M zone expanded the zone approximately 50 metres down plunge and 30 metres up plunge yielding up to 11.7 grams per tonne gold over 11.0 metres in hole SR19-13, whereas drilling on the O zone yielded several intercepts of greater than 50 grams per tonne gold and up to 150.8 grams per tonne gold and 49 grams per tonne silver over 1.8 metres in hole SR20-27, extending the known zone approximately 30 metre in depth and along strike for 60 metres (Equity Exploration Consultants Ltd. [2021-06-07]: Technical Report on the Scottie Gold Mine Property, British Columbia, Canada).
