The Mohawk (Lot 4571), 4 kilometres by steep road southeast of Camborne and east of Mohawk and Pool creeks, is similar to a system of mineralized veins along the south side of Pool Creek. See the nearby Spider mine (082KNW045).
The area is underlain by metasedimentary rocks of the Lower Paleozoic Lardeau Group, Broadview Formation, which includes medium grey to greenish quartzites, greywackes, carbonaceous phyllites and quartz sericite schist.
Two veins, the Mohawk and Fresno, cut the metasediments and contain galena, sphalerite and pyrite. The Mohawk vein, 1.2 metres wide, strikes 155 degrees and dips 72 degrees east. Samples assayed up to 1738 grams per tonne silver, 3.4 grams per tonne gold and 65.3 per cent lead (Annual Report 1914, page 261). The Fresno vein strikes 160 degrees and dips 80 degrees east. Samples assayed traces in gold and silver. Adits explore both veins.
It is associated with propylitized or silicified rock in the hangingwall and less commonly in the footwall of the bedding plane faults. The propylitic rock displays either a gradational contact to phyllite or gritty phyllite, where bedding is at a shallow dip, or by shear contact where bedding is steep. Galena and sphalerite occur in quartz - siderite stringers and lenses which form an anastomizing stockwork within the propylitic alteration zone. The majority of these fractures are oriented north to north-east with steep easterly dips. This type of mineralization is observed along the Excise - Mohawk vein. In the Mohawk area, this mineralization was intersected at a depth of 19 meters in DDH M87-02; the section 19.1 to 19.8 meters assayed 1.78 grams per tonne gold, 13.03 grams per tonne silver, 0.29 per cent lead and 1.65 per cent zinc (Assessment Report 19018).
Mineralization also occurs within the footwall of the bedding plane faults. Galena, sphalerite, pyrite and chalcopyrite is localized within thin concordant bands in contorted phyllites and argillites and also along jointing and fracturing planes within these rocks. This type of mineralization is characterized by the absence of quartz - siderite as the gangue and is observed only in the immediate vicinity of the bridge over Mohawk creek. This type of mineralization was intersected at a depth of 75 meters in DDH M86-01; a 1.0-meter-long core length of this material assayed 0.48 grams per tonne gold, 48.69 grams per tonne silver, 1.18 per cent lead and 2.0 per cent zinc (Assessment Report 19018).
Mineralization also occurs in north-northeast oriented quartz veins and stockwork zones that transect all structures. This mineralization is typical of that developed in the Spider and Eclipse mine workings and consists of massive galena with sphalerite and pyrite and is observed at all of the various prospects. Samples from this type of mineralization at the Excise workings (082KNW043) yielded grades of up to 11.38 grams per tonne (Assessment Report 19018). Sulfide minerals form either coarse clusters in a gangue of quartz and siderite (ankerite?) or what is termed “solid steel galena”; fine grained, banded material generally less than 0.30 meters wide. DDH M87-05 was collared in this style of mineralization; a section from 1.1 to 3.2 meters assayed 8 grams per tonne gold, over 100 grams per tonne silver, 2.8 per cent lead and 6.3 per cent zinc (Assessment Report 19018).
In 1963, Dakota Silver Mines Ltd. recovered 13.5 kilograms of silver, 1358 kilograms of lead and 1699 kilograms of zinc from 8 tonnes of crude ore.
In 1980/81 Westmin Resources cleaned out and resampled the oxidized surface showing on a group of claims which included the Mohawk and Eclipse (082KNW044) occurrences. Between 1985 and 1987, Triple M sampled the Eclipse mine workings, upgraded road access to the Spider mine workings, completed detailed VLF-EM and magnetometer surveys and completed four diamond drill holes for a total of 608 meters. Between 1986 and 1988 Royal Crystal Resources Ltd. optioned the Marlow claims, constructed log bridges to cross Mohawk and Pool Creeks, and drilled 14 holes for a total of 1,167.6 meters to test the Excise - Mohawk vein system. During 1989, Royal Crystal carried out additional geological mapping within the claim area, reviewed available exploration data and prepared a new compilation geological map. In the Mohawk area mineralization has been noted as occurring in several ways.
In 2016 and 2017, Explorex Resources Inc. completed programs of prospecting and rock and soil sampling on the area as the Silver Dollar property. A select grab sample of quartz vein float assayed 6.51 grams per tonne gold, 78.5 grams per tonne silver and 2.81 per cent lead (Chapman, J. (2019-03-20): National Instrument 43-101 Technical Report on the Silver Dollar Property).
In 2019, Mariner Resources Corp. completed a 624 line-kilometre airborne magnetic and radiometric survey on the area as the Silver Dollar property.
