Green Mountain Section
The Green Mountain section forms the western extremity of the Dawson-Green Mountain property and comprises 13 unpatented lode mining claims and one patented lode mining claim totaling approximately 108 hectares (268 acres) located 3 km west of the El Plomo section.
Green Mountain is interpreted to be the western, faulted offset extension of the mineralized trend on the Dawson section, exhibiting similar geochemistry and rock types. As such, the Green Mountain section is considered to be prospective for Dawson type gold mineralization. Discovered in ca. 1882, Green Mountain was mined for copper on a small scale from shallow shafts with a maximum depth 76.2 m (250 ft) on a massive sulphide horizon in the mineralized trend. Historical records indicate a small tonnage (1,187 t) of high grade material (12.6% copper, 3.8 g/t (0.11 oz/ton) gold and 47.6 g/t (1.39 oz/ton) silver), was shipped direct to a smelter early in the last century. Modern exploration programs targeting base metals were carried out by Phelps Dodge between 1979 and 1984 and by Inco Ltd. between 1992 and 1994. Phelps Dodge core drilled 13 holes totaling 2,172.6 m (7,128 ft) with the best hole GM-2B, drilled below the old workings intersecting 1.4 m (4.5 ft) grading 18% copper, 4.3% zinc and 181.6 g/t (5.3 oz/ton) silver at a drill hole depth of 123.5 m (405 ft) and remains open at depth*. Zephyr’s studies suggest this sulphide horizon is analogous to that in the hanging wall rocks or southern contact of the mineralized trend at the Dawson section. Research of historical data in Company files suggests the zone below, or footwall to the massive sulphides has not been tested for gold. The footwall zone in the mineralized trend is host to the gold mineralization at the Dawson section.
Seventeen grab samples collected on a reconnaissance traverse on the patented claim yielded encouraging results with five exceeding 1 g/t gold, including one sample of garnetiferous biotite gneiss which assayed 13.6 g/t gold. This rock-type is one of the principal gold hosts at the Dawson Gold section and further points to the gold prospectivity of the Green Mountain section. Grab samples are selected samples and are not representative of the mineralization hosted on the property. See news release of July 25, 2018.
