Hasbrouck Exploration
The Hasbrouck property consists of 28 patented mining claims and 583 unpatented mining claims covering an area of approximately 10,750 total acres within Esmeralda County, Nevada. The Three Hills property consists of 13 patented mining claims and 100 unpatented mining claims totaling approximately 2,000 acres.
West Kirkland has identified high-grade epithermal vein and bulk tonnage exploration targets on the two properties. Both properties have recently been expanded and new targets were acquired.
Historic work has been focused predominantly on the known deposits. By September 2014, West Kirkland completed approximated 2,000 meters of reverse circulation and core drilling on the Hasbrouck and Three Hills deposits.
Hasbrouck Deposit
At the Hasbrouck deposit, mineralization is structurally controlled and West Kirkland intends to test newly developed geological concepts.
Drilling in the summer of 2014 followed-up on rock chip samples collected by West Kirkland focusing on an underexplored area on the northeast flank of Hasbrouck Peak. The sampling returned high grades, including 24.6 g/t Au, 6.65 g/t Au and 4.13 g/t Au in select rock chips, and indicated the potential to develop significant tonnage in close proximity to existing resources. Although over 600 holes have been completed at Hasbrouck and Three Hills by previous owners, there is no documented drill testing in this area. The area is within 100 meters of the conceptual pit outline in the ongoing prefeasibility study.

Drilling returned 6.09 meters of 0.38 g/t Au with 6.48 g/t Ag starting at depth of 6.10 meters in hole HSB14R-009 and HB14R-010 returned 4.57 meters of 0.66 g/t Au with 12.2 g/t Ag starting at a depth of 7.62 meters. Each mineralized intercept terminated at the contact between the Siebert formation and the underlying Fraction Tuff. A second phase of mapping, sampling, and trenching will be completed in areas of thicker Siebert formation towards the potential pit area, with the goal of establishing refined drill targets with potential for thicker mineralized intercepts. The Siebert formation, which hosts the main deposit, thickens toward the known resources of the Hasbrouck deposit.
Three Hills Exploration
At Three Hills, the best grades occur where structures have prepared at the contact between the Siebert and Fraction formations. WKM will be systematically evaluating these targets in the coming months.
In July-August of 2014, West Kirkland drilled four exploration holes on the eastern flank of the Three Hills deposit, testing a newly developed structural interpretation of the deposit. The company has identified northwest structures as a potential host of high-grade mineralization. The company tested for zones of structural preparation near the contact between the Siebert formation and the Fraction Tuff.

Hole TH14R-004 returned 50.29 meters grading 0.73 g/t Au and 3.22 g/t Ag within a zone of intersecting structures and includes 9.15 meters at 2.27 g/t Au. Mineralization started 26 meters above the contact between the Siebert and Fraction Tuff and continued 24.4 meters below the contact. This intercept is approximately 70 meters northwest of hole TH12R-15, drilled by a previous owner, which returned 66 meters of 3.3 g/t Au in a similar setting at the same elevation.

Hasbrouck and Three Hills Geology
The Hasbrouck Deposit is a low-sulfidation, epithermal gold–silver deposit and is located in the western portion of the Divide Mining District. Hasbrouck Mountain, which forms the core of the deposit, is composed primarily of tuffs and epiclastic sediments of the Siebert Formation, which is underlain by Fraction Tuff. Several occurrences of chalcedonic sinter, deposited during hot spring activity, have been mapped near the top of the mountain. Gold and silver mineralization outcrops over much of the western half of Hasbrouck Mountain.
The currently-known mineralization extent is approximately 1,900 ft east–west by 1,100 ft north–south and has been drill-tested to a depth greater than 900 ft. Mineralization is open to the north and south at depth.
The Three Hills Deposit is also a low-sulfidation, epithermal gold deposit, with mineralization associated with structural features, rock unit contacts, and with high permeability lithology. Gold mineralization occurs in a zone of pervasive silicification within the Siebert Formation and the upper 10 to 30 feet of the Fraction Tuff. The contact between these two units contains consistently higher grades of gold and is commonly argillized. The currently known resources extend approximately 600 ft east–west by 2,000 ft north–south and have been drill-tested to a depth greater than 1,000 ft. Mineralization remains open to the east, and at depth. The Company continues to explore both deposits.
