The Midway property includes the Texas (Lot 662) and Granada (Lot 869) reverted Crown grants, located six kilometres west of the village of Midway in south-central B.C.

The Midway property contains a copper-gold mineralized system related to skarn alteration within Triassic sediments. These sediments, together with lesser Triassic volcanics and minor Paleozoic volcanics, are exposed within the Midway Window or Inlier, centrally located in the north-trending Eocene age Toroda Creek Graben. This window is surrounded by Eocene volcanics and epiclastic sediments.

The Triassic sediments consist of two major stratigraphic units, a lower limestone and an overlying chert-pebble (sharpstone) conglomerate. These are extensively intruded by at least four phases of monzonitic porphyritic intrusions interpreted, on regional considerations, to be Cretaceous in age. The "crowded-feldspar porphyry" phase, perhaps later than the rest, appears to be genetically related to the formation of extensive garnet-epidote-pyroxene skarn along the limestone - conglomerate contact. The skarn is locally well mineralized with chalcopyrite and pyrite. The stratigraphic units, the intrusions, and the skarn are divided by northeast trending faults.

Although only two crown grants remain in the Midway property area (the Texas and the Granada), a copy of the 1932 claim map for this area shows a total of 19 former claims and crown grants. On the Texas reverted crown grant, a number of small pits and adits explore an area of chalcocite mineralization in pale epidote-hematite-diopside skarn and skarny limestone. Locally up to 10 per cent disseminated or bands of chalcocite, with lesser chalcopyrite, occur. Massive magnetite also occurs along a volcaniclastic/limestone contact in the Brooklyn Formation at the Texas adit.

A large northwest trending copper-gold (plus arsenic and zinc) soil anomaly occurs at the Texas. Values to 4.72 grams per tonne gold, 172.6 grams per tonne silver, 7.7 per cent copper and 15,478 ppb mercury were derived from grab samples from this area (as reported in Assessment Report 27466). The presence of typical skarn minerals and the traditional skarn driven exploration in the Greenwood area have resulted in this zone being categorized as a copper-gold skarn system, although the very high mercury and the gold-mercury association are not typical of skarn systems but more suggestive of epithermal mineralization.

To the northeast of the Texas, several workings are located on the former Potter-Palmer crown grant including an old adit and a large surface scrape on a skarn zone with local pods of massive pyrite, chalcopyrite and locally chalcocite. Nearby, a gold soil anomaly defined by Battle Mountain occurs and is associated with a bleached fine grained volcaniclastic cut by up to 10% silica-pyrite stringers.

The Granada reverted crown grant is situated about 800 metres northwest of the Texas showings. Little is documented about the mineralization in this area. A thick sequence of Brooklyn Formation sharpstone conglomerate is mapped in this area, and a large copper soil anomaly extends northwest from the Texas showings to cover this zone.

Mineralization in the Texas area is reported to have characteristics of copper-gold skarn mineralization, volcanogenic magnetite-sulfide mineralization and epithermal-style gold mineralization.

Work History

In 1894, a tunnel had been run on the Texas claim for 9 metres. In 1895, the old tunnel was in 23 metres and a new one was in 15 metres. In 1897, the Texas was Crown-granted to Edwin Graham. In 1922, new work consisted of trenching and a 4.5 metre tunnel. In 1928, tunnelling was continuing 137 metres lower in elevation than from where a 20 metre deep shaft was excavated with no positive results. In 1962, Yankee Dundee Mines (Midway Syndicate) held the Texas and Granada claims and other claims and drilled 4 holes totaling 122 metres. During 2008 through 2012, Grizzly Discoveries Inc. completed programs of rock and soil sampling on the area as the Copper Mountain claim black of the Greenwood property. During 2015 through 2018, Kinross Gold Corp. completed programs of geological mapping, geochemical (rock, soil and silt) sampling and diamond drilling on the area as the Midway property.
