Long Island Mining
==> picture [330 x 368] intentionally omitted <==
==> picture [111 x 45] intentionally omitted <==
Long Island Study based on strip mining strategy designed to significantly reduce waste mining costs:
-
Short, horizontal hauls to backfill void, instead of conventional longer hauls out of the pits to remote, elevated waste dumps
-
Modification of the mining strategy possible given tabular geometry and strike extent
-
Tropicana LoM pit identified for use as the starter pit
-
25-30% potential reduction in unit mining costs per tonne with introduction of Long Island mining strategy
Current strategy is to use the LoM Tropicana pit as a starter pit, or void, which will be backfilled with material from Boston Shaker to the north and Havana to the south

Capitalised Waste Stripping increased from $29M to $36M to revised forecast of $37M to $43M due to accelerated mining rates and grade streaming
-
Improvement Capital increase from $2M to $3M to a revised forecast of $7M to $8M to deliver an additional 200 - 400ktpa plant throughput by end of CY17
-
No change in AISC although likely to be at the higher end of FY17 guidance of $1,150/oz to $1,250/oz
