SnapshotZonia fits into new copper market dynamics perfectly offering a viable smaller scale and lower cost operation that can be permitted and constructed in half the time required on average to develop new larger concentrate mines. Being a past producer, Zonia’s mineralization is pre-stripped resulting in a 1:1 strip ratio for our new operations, and it has power and water on site.

World Copper has adopted a two-phase plan to move the Zonia project down the production track. Phase one would target only the portion of the project located on private land. To satisfy the parameters of a bankable feasibility study Phase one will move to convert a major portion of the inferred resources in from the PEA to indicated resources. This will most likely entail an infill drilling campaign. Other Phase one programs will include environmental studies, land and water use permits, metallurgical studies, mine planning, engineering, financing modelling and construction planning.

Deposit type

  • Porphyry
  • Metamorphic

Summary:

The Zonia deposit is hosted by steeply dipping, northeast-trending, Precambrian metamorphic rocks of the Yavapai Series, comprising schistose subvolcanic intrusions, volcanic flows and tuffs, and finegrained sedimentary rocks, enclosed in Precambrian granitic plutons. Portions of the area are covered by post-mineralization Quaternary basalt, fanglomerate, and alluvial material. Mineralized units consist mainly of highly variably foliated quartz- monzonite, felsic schist, and diorite, with highly schistose phyllite and chlorite schist along the southeast margin.

The Zonia copper deposit has a north-easterly strike length of about 2,400 m (8,000 ft) and horizontal width varies from 60 m (200 ft) to 460m (1,500 ft). The deposit consists of multiple mineralized zones that dip at various angles to the northwest. The zones are generally in the order of 200 ft (60 m) wide and commonly occur in sub-parallel groups of three or more. Most of the deposit has been drilled to depths of 120 m (400 ft) or less.

The Zonia copper oxide deposit is the highly oxidized portion of a previously supergene-enriched metamorphosed porphyry deposit. Oxidation of the original chalcopyrite mineralization and younger secondary supergene chalcocite has been pervasive and deep, extending down over 250 metres (874 feet) in the central pit at the historical Cuprite mine shaft. Chrysocolla, malachite, azurite, tenorite, and cuprite are the most common copper minerals.
