Here's a bit from Heron's website about their nickel laterite project - Feasibility, CAPEX, OPEX... stuff... similar to Young but bigger.

At Heron's 100% owned Jump-up Dam Project, exploration success continued with new resource estimates for Jump-up Dam and Boyce Creek. The Jump-up Dam resource was updated to include 22mt of ore at 1.05% nickel, classified in the indicated category. Heron's total resources stand at 987mt at approximately 0.74% nickel - just short of 1 billion tonnes of ore.

Pre-Feasibility Study
On 25 January 2008, Heron announced the PFS at Jump-up Dam had concluded that based on current configurations, the Heap-Leach process does not make an adequate return on investment.

Trial mining at Jump-up Dam will continue as originally planned for mining studies and grade reconciliations; however, the proposed demonstration heap leach operation will be placed on care and maintenance.

The PFS estimated capital expenditure at A$681.9 million and operating costs of A$6.39 per pound of nickel production. These costs represent escalations of approximately 50% and 56% respectively from the Scoping Study completed in April 2007. Escalations in capital expenditure are due to significant increases in the capital cost of acid plants and power plants (97% increase). Escalations in operating costs are predominantly due to sulphur price rises, and the impact of higher oil prices on transport and mining costs. Ongoing increases in construction and labour costs also contributed to the escalated PFS outcome.

Heron will draw on opportunities presented by its recently announced Technology Licensing and Product Supply Agreement to fully evaluate Atmospheric Leach as a processing option for Jump-up Dam and surrounding deposits. Atmospheric leaching allows beneficiation to provide a higher leach feed grade and better utilisation of the resources within the Yerilla District. Heron has gained specific experience in laterite beneficiation during the past eight years and will be applying this knowledge to the Kalgoorlie Nickel Project.

Significantly, nickel laterite discoveries during the last year at Jump-up Dam South, Boyce Creek, Aubils and Pianto Road will now provide a major opportunity for nickel production increases in future Atmospheric Leach development scenarios.
