Eagle Hill Exploration Corporation is a Canadian mineral exploration company focused on the exploration and development of the high-grade Windfall Lake Gold Deposit, located between Val-d'Or and Chibougamau in Quebec, Canada. This area is known for its gold and copper production and excellent infrastructure for exploration and mining.
In April 2015 Eagle Hill published the results of a Preliminary Economic Assessment (“PEA”) for the Windfall Lake Project. The PEA outlines the design of a 1,200 tonne per day underground mine producing 106,200 ounces of payable gold annually for 7.8 years at an average total cash cost of $558/oz of gold (US$480/oz). At a base case gold price of US$1,200/oz the project has a pre-tax internal rate of return (“IRR”) of 23.6% and a pre-tax net present value discounted at 5% (“NPV5”) of $241.4 million. Initial project capital costs are estimated at $240.6 million. Eagle Hill intends to complete a pre-feasibility study for the Windfall Lake project by 2017.
The current mineral resource is estimated at 2,762,000 tonnes grading 8.42 g/t gold for 748,000 ounces in the indicated category, and 3,512,000 tonnes grading 7.62 g/t gold for 860,000 ounces in the inferred category. 1 High-grade mineralization has been identified in multiple zones, yet only a small portion of the 12,400 hectare property has been tested to date. Mineralization has been identified only 30 metres from surface in some areas and as deep as 870 metres in others, with significant potential to extend mineralization along strike and at depth. Many gold deposits in this region continue well below 1,000 metres depth.
Next steps include extending the existing ramp and taking a bulk sample, drilling both from surface and underground with the objective of expanding and upgrading the quality of the resource and testing continuity of grade, and finalizing the various studies required for a pre-feasibility study.
1. The resource estimate was calculated by SRK Consulting (Canada) Inc. using a 3 g/t cut-off grade, assuming an underground extraction scenario with an assumed gold price of US$1,200 per ounce and metallurgical recovery of 96%, with an effective date of November 13, 2014. Inferred resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. It cannot be assumed that all or any part of the inferred resources will ever be upgraded to a higher category. Mineral resources are not mineral reserves and do not have demonstrated economic viability. See Cautionary Notes.
