DST required a demonstration plant to further prove its patented goldextraction process at an industrial scale of 15 tons per day. It wanted to show that its process could operate successfully at a much larger throughput than its pilot plant had been able to produce. As well, the pilot plant had operated in batches.

The deposit contains ounces of gold per ton of highgrade ore and can be acquired at a cost of 10 per ton of ore (cost of mining ore at site). A sodium cyanide process is used to extract the gold from the ore, and various other processing techniques are used to produce % pure gold bullion from the ore.
