The Hasbrouck gold-silver project is located in the northern part of Esmeralda County, near the town of Tonopah, Nevada, USA. The project is 75% owned by West Kirkland Mining (ERM) and 25% of Clover Nevada, a wholly owned subsidiary of Waterton Precious Metals Fund II Cayman.
The project is proposed to be developed in two phases. Phase I involves the development of the Three Hills gold deposit that is to be expected a production period of two years. Phase II is the development of Hasbrouck gold-silver deposit include, are likely to have six years.

The pre-feasibility study (PFS) for the gold and silver project in Nevada was completed in June 2015 and the final approval from the government for the construction of the Three Hills Mine from April 2016. The Perform on the approval of Phase II under environmental assessment began in May 2015, the initial cost to the Three Hills mine is expected in production, is estimated to be $ 54.3 million, while Hasbrouck is funded from the production in Three Hills mine
Hasbrouck Gold-Silver Project Reserves And Production
From June 2015, the Three Hills mine is proven to keep estimated combined and probable reserves of 9.65 million tonnes (Mt) grading 0.018 oz Au / t containing 175,000 ounces of gold.
The Hasbrouck Mine is estimated that proven and probable reserves of combined 35.671Mt grading 0.017 oz Au / t and 0.297 oz Ag / t, with 588,000 ounces of gold and 10.56 million ounces (Moz) of silver.
The hold annual production capacity of the project is estimated at an average of 71,000 ounces of gold. The project is expected to produce 138,000 ounces of gold at the stage in Phase II I and 429,000 ounces of gold, while silver production is estimated in the phase II to 194,000 ounces per year.

Geology And Mineralization
Includes , the two deposits are oxidized, low sulfidation, epithermal vein systems with host rocks tuffs and sediments of Siebert formation with limited mineralization within the underlying fraction Tuff. Gold and silver mineralization is either on the surface or near the surface, above the water level, and is open at depth and to a limited extent in the Northwest and East.

Mining And Processing Of Gold And Silver Project In Nevada
The Three Hills deposit is proposed to be mined as a run-of-mine open pit heap leach conventional open pit, truck and- shovel to integrate operations, while the deposit Hasbrouck be mined as an open pit heap leach ore crushed. The former is to integrate a 15,000t / d heap leach pad, while the latter incorporate a 17,500t / d leach pad.
The ore from two Phase II secondary cones with a primary jaw crusher, crushed crusher, and a tertiary high-pressure grinding roll (HPGR). The comminuted product is transported in a kneading machine with cement and to the leach pad.

The leaching gold and silver from the Hasbrouck deposit and the gold from the Three Hills deposit at their respective locations with dilute cyanide solution that pass on through carbon columns to extract a precious metals.
The loaded carbon is then in adsorption-desorption-recovery (ADR) plant that are in the Three Hills . The loaded carbon from the Hasbrouck mine will be transported by trucks to the ADR facility.

Infrastructure For West Kirkland Mining Flagship Project
The water required for the project is proposed to either be purchased from the Tonopah Public Utilities “(TPU) wellfield in Ralston Valley via an underground pipeline or installed next to each deposit wells.
“the two deposits are oxidized, low sulfidation, epithermal vein systems tuffs with host rocks comprising the sediments and Siebert lineup. “
The current for phase I of liquefied natural gas (LNG) -based generator are supplied, while the performance for the next phase of NV Energy supplied regional power distribution company, via a transmission line. A substation is on Hasbrouck location be built and both sides are a diesel-fired generator integrated to serve as back-up.
infrastructure for phase I, a laboratory will include a reagent storage building, a process Store and a warehouse, and serve three trailers as offices, will be relocated to Hasbrouck location in the next phase.
Important infrastructure at Hasbrouck site is building inclusion include administrative offices, a warehouse, a test laboratory and accommodations.
