The annual average tonnage mined and sold from the site are best predictions since many factors such
<br /> as the economy, competition, etc. greatly affect the actual sales.
<br /> The life of the gravel operation will be approximately 15 years. Where the gravel is mined from is not
<br /> easy to determine since it is very dependent upon the gold operation. If the gold operation is viable over
<br /> the 12-13 years shown in the plan, a large part (60,000 tpy) of the gravel sold from the site will be the
<br /> waste gravel from the gold plant. If the gold operation is uneconomic, gravel will then be aggressively
<br /> mined from the gravel mine area as shown on Map C-2. For planning purposes, it is predicted that the
<br /> gravel operation will be in place 15 years at an average product sales rate of 130,000 tons per year,with
<br /> 2 possible scenarios:
<br /> Scenario 1
<br /> Year Gravel from piles Gravel from gold Gravel from Total Gravel (tpy)

<br /> 15 0 0 130,000 130,000
<br /> Total 1,230,000
<br /> Scenario 2: The gold mine does not operate for any significant period of time. In this case, the gravel
<br /> mine will produce all sold material from the gravel mine area,which is basically 2,000,000 tons over the
<br /> 15 year period. Almost all of the previously mined areas are reclaimed from gravel mining.
<br /> In either scenario, front end loaders will be used to deliver the raw gravel to the crushing, screening and
<br /> wash plants for separation into various products. Fogger sprays will be present in all three plants to keep
<br /> dust down. The crusher will also employ sprays. The plants will be located to minimize impacts to the
<br /> town of Alma.
