Hot Rock Limited is an Australian energy company formed to develop geothermal energy in Australia and overseas.
Strategically, the Company is focussed on exploring and developing its extensive portfolio of volcanic prospects in Chile and Peru complimented with Hot Sedimentary Aquifer prospects in Australia.
The Company moved early and acquired a wholly owned portfolio of projects with good evidence for geothermal reservoirs suitable for electricity generation in countries with attractive infrastructure, markets and government policy.
Joint Ventures
- HRL and Energy Development Corporation (EDC) entered into joint ventures on two geothermal projects in each of Chile and Peru.
- EDC will acquire a 70% interest by paying HRL up to US$4m in cash, sole funding of certain resource development costs in respect of each of the projects to financial close.
- The resource development stage of each project is expected to cost up to US$12m and includes geological, geochemical, geophysical surveys and at least one production well.
Chile
- Planning is advanced for large (>100 station) MT surveys to be run at each of the Longavi and Calerias projects in Q1 2012 to more closely delineate the geothermal resources for selection of exploration drilling targets
- Land access and indigenous community approvals have been obtained at the Santa Macarena project and geoscientific work is now commencing
- Three earlier filed but not granted exploration concessions have been resubmitted and these are now likely to be granted
- Further large international companies have taken up aggressive geothermal tenement positions in Chile. HRL remains a major tenement holder
Peru
- Community information programs and land access negotiations have been successfully completed at the granted Chocopata and Quellaapacheta projects. Detailed surface exploration is to commence as soon as environmental clearance is obtained
- An application for an exploration authorization has been granted for the Turu project and a further application submitted for a new prospect at Huisco. HRL is now holding 4 granted authorizations in Peru, with 5 more applications in process.
Otway Basin
- HRL holds over 27,000km2 covering a large part of the on-shore Hot Sedimentary Aquifer (HSA) geothermal targets in the Otway Basin, Victoria.
- Koroit Project in the Otway Basin contains stored heat of indicated resource of 7,800PJ and inferred resource of 59,000PJ to a depth of 4000m.
