The Rovina, Colnic, and Ciresata porphyry deposits are the principal targets for exploration and mining within the Rovina Valley Project (RVP), with their locations defining a north-northeast trend. The Rovina porphyry is the northern-most deposit, with the Colnic porphyry lying approximately 2.5 km south of the Rovina porphyry, and the Ciresata porphyry approximately 4.5 km south of the Colnic porphyry.

Geometry of the mineralisation and host porphyries is different for each of the deposits. At Rovina, the host porphyries are generally cylindrical and vertical. At Colnic, the porphyries are lobate, with mineralisation decreasing with depth and a phyllic-altered cap locally preserved. Both Rovina and Colnic porphyries intrude extensive igneous-magmatic breccia carapaces, whereas Ciresata mineralisation is centred on a relatively narrow subvolcanic “neck” with a significant amount of mineralisation hosted in adjacent hornfelsed sediments.

Rovina Mineralisation Descriptions
Gold-copper mineralisation is associated with pyrite-chalcopyrite-magnetite occurring in veinlet stockworks and as finely disseminated grains. Oxidation is restricted to the uppermost few metres, except for a small area in Baroc Valley at the Rovina porphyry where weathering oxidation is 15 m to 25 m deep within the copper-gold mineralisation. In this area, secondary copper minerals malachite and chrysocolla are observed in the weathering zone, and minor occurrences of supergene c ........

All deposits will be mined utilising conventional truck and shovel methods to supply ore to the ROM tip and waste to the respective pit’s waste crushing and conveying station, which will transport the waste to the Colnic stockpile area and backfill the Colnic pit.

A LOM schedule has been developed to supply one processing plant for the full LOM. The processing plant has a planned throughput of 7.2 Mt/a (Colnic pit and then Rovina pit) and a LOM of 16 years, excluding the Colnic low-grade stockpile. The LOM schedule considers the in-pit and stockpile blending requirements during the life of each pit, as well as the changeover from Colnic to Rovina ore supply to the processing plant.

The Owner’s mining fleet will be responsible for all mining-related earthmoving activities.

Most of the ore and waste materials will be drilled and blasted as there is a nominal amount of free dig/oxidised materials.

Free-dig and blasted waste will be loaded with 200 t class hydraulic backhoe excavators, hauled with 90 t haul trucks, and stockpiled at designated waste stockpile locations, which will be systematically dozed and levelled to allow the stockpiles to be raised in accordance with the design parameters.

Free-dig and blasted ore will be loaded with 200 t class hydraulic backhoe excavators and hauled with 90 t haul trucks to the plant feed ROM pad. There the ore will either be direct tipped into the crushing facility or placed on the RO ........
