Visualized Outcome: Discovery Harbour: Caldera - 1,500 tpd UG Sleeper Clone
The Caldera project owned 100% by Discovery Harbour is located in Nevada's Humboldt-Toiyabe National Forest and falls under the jurisdiction of the USFS. The analogue target is the low sulphidation epithermal Sleeper deposit whose high grade set of veins was mined in 1986-1996 by Amax by open pit and milled with 90%-95% recovery to produce 1,219,880 oz gold. About 45 million t of lower grade stockwork ore averaging 0.7 g/t gold was heap leached with a 49% recovery to produce 438,609 oz gold. Total throughput for a mill with initial 500 tpd capacity is not available but head grade seems to have ranged 10-15 g/t annually. The lower grade material averaging 0.4 g/t still in place has been the subject of modern economic studies. Because Caldera has already seen lots of exploration for disseminated Round Mountain type mineralization within a couple hundred metres of surface, and the exploration model is to assess the projected voiling zone at a vertical depth of 300-500 metres for bonanza vein mineralization within the two main structural trends, only the high grade portion of Sleeper (4 million t @ 13 g/t gold) that can be underground mined is used for this OV.

MSV (Market Cycle S Curve): Market Speculative Value represents the typical market pricing pattern of a new discovery as it moves through its exploration-development cycle. The irrational pricing behavior of the yellow channel contrasts with the fair speculative value of the blue channel as defined by the rational speculation model because during the pre-economic study stages there is great uncertainty about how big the discovery will turn out.

View Detailed Visualized Outcome (KRO Members Only)
Disclaimer: A visualized outcome is one of many possible outcomes for an exploration project as it moves through the 9 stages of the exploration-development cycle from grassroots to a producing mine with failure as an outcome at any point along the way. The range of possible outcomes for the physical nature of a deposit shrinks after delivery of an initial 43-101 resource estimate. While the nature of the deposit constrains the range of mining scenarios, the cost assumptions will vary as the project moves through the feasibility demonstration stages of the cycle, which affects the economic value of the final outcome. This economic value will also vary according to the prices of the metals targeted for extraction which may change during the years it takes for a project to become a mine. An outcome visualization is thus a compilation of best guess assumptions for the key variables that drive the discounted cash flow model, the basis for assigning an economic value to a mine. An OV is not intended as a prediction, but rather as a framework that allows the incorporation of new information generated by the exploration-development cycle for the project into a valuation model on an ongoing, dynamic basis.
