The Kalavasos Project, consolidates 14 massive sulphide deposits within a recognized VMS camp located north of Larnaka. The Company has identified multiple target types within the current portfolio for evaluation including remnant Mineral Resources left following premature closure of some of the mines.
- The Kalavasos Project comprises 5 contiguous licences covering a combined area of 18.45km2
- Recorded production included 4.68 million tonnes at >1.0% Cu.

Multiple Target Types at Kalavasos
- High-grade Sulphide Ore – A number of the former producing mines are reported by the Mines Department to contain remnant ore totalling 2.58Mt @ 0.5 – 2.5% Cu (+ Au), to be re-evaluated as a potential source of mineable ore.
- Previously Undiscovered High-Grade Sulphide Mineralisation – Previous mining operations focused on those easily accessible, high-grade deposits visible at surface. No systematic exploration was completed in areas where potential mineralisation is covered by overlying rocks. Three new licences contiguous with the existing VMS camp have never been explored in any detail. This is an unusual situation as under normal circumstances these highly prospective areas would have been explored in detail as part of a systematic programme. These licences will be targeted for previously undiscovered high-grade sulphide VMS deposits.
- Mineralised Dumps & Low-Grade Stockpiles – Numerous dumps occur throughout the licences close to former producing mines. Copper mineralisation is visible in some dumps and will be evaluated as a possible low-cost, short lead-time, revenue stream. Gold mineralisation largely ignored by previous miners is known to occur within the Kalavasos Camp and prospective rocks will be analysed for the precious metal. A gold by-product in copper ore and concentrates will add value and enhance economic viability.
- Bulk Tonnage Potential – Historic mining focused on high-grade copper ore and not the stockwork-type lower-grade disseminated mineralisation that typically sits in the footwall, beneath the high-grade sulphides. Stockwork-type mineralisation is clearly evident at surface in some of the former open pits. This will be mapped, sampled and evaluated as an additional future source of feedstock.
- Gold By-Product – Gold was largely ignored by previous miners with the exception of the high-grade “muds” located at surface. The implication is that lower grade copper mineralisation may now represent a viable resource based on the presence of a gold by-product.
