Ann: Sulphuric Leach Project Focus, page-42

Sorry Doc but I won't get the chance to address your question more directly until later:

Keeping in mind the announcement states "on-site sulphuric acid plant to produce acid and steam for process heating and power generation orthe alternative of imported acid and/or contract power generation" so I assume management are evaluating both avenues of either producing our own or importing acid and contracting for power.

This link may provide some info in the meantime..

"Rowe has also earned himself some brownie points with federal regulators through the design of the planned sulphuric acid plant, which will produce excess energy as a by-product that can go back into the grid, qualifying as a green source of power"

TSX:KAT may also be of interest also and you can read further below, I'll also include a link:

"The Board also approved US$237 million in capital expenditure spread over 2018 and 2019 to construct a Sulphuric Acid and Sulphur Dioxide production plant at KCC. This will improve the reliability of the supply of these reagents to the WOL processing circuit. The acid plant is designed to produce 1,900 tpd of of Sulphuric Acid, 200 tpd of Suphur Dioxide and 17MW co-generated power. This will reduce KCC's reliance on imported volumes of reagents brought to the mine through various international borders. The Internal Rate Of Return (IRR) for the Sulphuric Acid and Sulphur Dioxide production plant project is expected to be approximately 60%. The hot commissioning of this plant is expected to commence in

H2 2019"
