The Nevada Properties
The Ecru project is located 40 kilometres southeast of Battle Mountain in Lander County, Nevada. It is located in the heart of the highly endowed Battle Mountain-Eureka trend (see Figure 1), adjacent to Barrick's Pipeline, Cortez Hills and Goldrush deposits which have a collective gold endowment of approximately 50 million ounces.
The project is situated in an area covered by a veneer of transported colluvium ("pediment") and is centered on a large gravity high that is interpreted to represent an upthrown block of teh same carbonate rocks that host the nearby world class deposits (see Figure 2).
Historic drilling by third parties on adjacent parts of the same gravity high has yielded significant gold minerlization in both the favourable carbonate rocks of the lower plate and the less favourable upper plate sequence, with one upper plate sample in excess of 10z/t gold. Geochemical sampling of the pediment has also defined an anomaly within the transported colluvium overlying this gravity anomaly.
Additionally, the project is interpreted to contain geology analogous to that at Barrick's Pipeline deposit, which occurs where lower plate carbonates have been throust over teh upper plate sequence, with the receptive carbonate host rock and mineralization being exhumed (exposed) by partial erosion of the overlying rocks, before being buried beneath more transported colluvium (see Figure 3).
The South Roberts project is located in Eureka County, Nevada, 35 kilometres northwest of Eureka. It is located on the Battle Mountain-Eureka trend of world class gold deposits (see Figure 1) and on teh western margin of the northern Nevada rift in a very similar setting to Barrick's Goldrush deposit to the north.
The project covers the southern extension of an uplifted block containing known gold mieralization that plunges southwards beneath transported volluvium (pediment) as evidenced by a gravity anomaly (see Figure 8) and confirmed by a six hold first pass drilling program conducted in 2014.
Within this area, several targets have been defined by northwest trending structures (considered a dey ingredient in the formation of Carlin-style gold deposits) with coincident Carlin-style geochemical anomalism in the overlying pediment (ie, coincident elevated gold, silver, arsenic, antimony, mercury and thallium see Figure 9).
The previous first pass drilling program comprised six wide (1 kilometre) spaced holes drilled through the pediment and into expected lighologies - namely the appropriate "caprock" to act as a seal, adn favourable receptive carbonate host rock unit beneath it (see Figure 9). The lithologies intersected in this drilling also contain textures indicative of hydrothermal activity (solution collapse breccias) and anomalous gold (up to 0.28g/t).
Two of these holes targeted the twin gold peaks observed in partial leach geochemical sampling of hte colluvium, and intersected gold both in the cap rock and in the favourable host carbonate beneath it, in a position subsequently interpreted to be on the flanks of an anticline (see Figure 9). However, in partial leach geochemistry, anomalies classically form either side of the source, adn not directly above it in a pattern known as a rabbit ear anomaly. Theoretically, the source of the anomaly (and the best part to drill) is located directly beneath the dead spot between teh two flanking highs. This position coincides witht the crest of a interpreted anticline in a untested position midway between these two holes, representing an obvious drill testable target (see Figure 9).
