Garin is situated approximately 70 kilometres to the east of the well-known mining city of Copiapo. The primary tenements held are a series of mining claims (Mensuras), covering approximately 8.5 km2.
This district is primarily associated with silver mining. Gold and copper extraction have also been undertaken but to a lesser degree. Silver mining in the district started in a small way during the mid-nineteenth century, continuing intermittently to some reasonably extensive artisanal silver mining taking place in the late 1970’s, and continuing into the early 1980’s. A characteristic of the Garin silver mines is that they operated longer than most when the silver price was low, due to the locally high silver grades encountered in the mining district.
There are a number of Exploitation Concessions of the old code inside the area covered by Comet’s tenements indicated in green and orange in the plan below. These areas (as granted Mensuras) take precedence over Comet’s claims in the area.
The key external tenement is Copiapina 1 al 10 (green outline in plan above), over which the Company has an agreement to enter in an option.
The bulk tonnage target at Garin is a shallow seated large tonnage porphyry copper gold system. The potential for this target is supported by the geology, mineralisation and alteration patterns.
Multiple high grade gold and silver bearing structures occur pervasively through the tenements. Further targets have been defined by reconnaissance sampling.
Professor Ferenc Molnar a renowned expert in South American porphyries and IOCG’s said:
“The most prominent feature of the Garin property and surrounding areas is the large propylitic alteration zones centred on the argillic alteration area of Copiapina. The characteristics of alteration and mineralization at Copiapina (disseminated-stockwork ore under an advanced argillic-phyllic alteration blanket) together with surface mineralisation features observed in the field invokes that mineralization of the whole area could be modelled in a porphyry intrusion related magmatic-hydrothermal system”
Comet has undertaken a thorough surface and underground rock chip sampling program over an extensive area of the Garin Project. There are a multitude of mineralised structures in the tenements and there is significant detailed work remaining to be carried out. The Company now has available approximately 450 samples from the Garin project with extensive digital field notes for the sampling program.
There are numerous wad stockwork occurrences in the Garin property. Wad is an old mining or generic term for any black manganese oxide or hydroxide mineral rich rock in the oxidised zone of various ore deposits. Typically wad is closely associated with various iron oxides. Wad often contains significant amounts of hydroxides/oxides of other metals and adsorbed metals such as Ni, Co, Cu, Fe, and other transition metals such as silver, as well as alkali elements.
These stockwork zones of wad at Garin are often found associated with the areas between the epithermal vein swarms and present potential bulk tonnage targets.
