Copper Mine – Jujuy – Argentina

The complex Bronze Martin is in the Northwest Region of Argentina, it encompasses Martin Bronze Mine itself, the mining camps Copper King Maximilian, Santos Copper and Martín Ignacio.


The deposit is situated in the far north of the Sierra Santa Barbara, at the intersection of the geographical coordinates 64 º 59 ‘West and 24 º 03’ South approximately in the district of Palma Sola, Santa Bárbara Department, in the Jujuy Province, and is 150 Km ENE of San Salvador de Jujuy.

The mine is located on the No. 1 and No. 6 provincial roads and access via Provincial Highway No. 6. And then by a dirt road of 12 km in length, to get to the place of exploitation which lies wholly within the property, which also has several roads that connect different parts of it.
The mine has a medium voltage power line and hot water springs that can supply both drinking water and water for the industrial operations. Martin Bronze is 18km (tarmacked road) from the train station (Yuto) and 105km from the International Airport Dr. Horacio Guzman. “
Using the “Paso de Jama”, is easily accessible to deep-water ports along the Chilean coast, a distance of approximately 800km.

Type of deposit, reserves and percentage of the deposit

The deposit is stratus type.
The different types of reserves and ley are:

Reserve Type

Quantity (MT)






1.5% Zn – 3oz Ag /MT  – 0.5g/MT Au



2.5 or better

3oz Ag /MT  – 99% cretainty




Totality of Mining Field

The mine has several certified analysis, undertaken by both academic institutions and by private laboratories.


The ore consists of massive malachite, compact, very fine grained, or radial acicular crystals up to 0.5-mm clasts cemented sandstone, and fill cracks and microcracks.
To a lesser proportion there is brochantita, azurite, hematite, limonite, chalcocite, covellite, pyrite and chalcopyrite.
The sulfides are isolated individuals of 0.01 to 0.1 mm partially altered to minerals and iron copper oxide.

Regional geology

The deposit consists of a sedimentary sequence of units that range from Paleozoic to Cenozoic.
The Paleozoic sediments are composed of Ordovician shale and sandstone, quartz sandstone and quartzite of Devonian (F. Ao. Colorado), then a succession unconformably deposited continental-marine of the “Salta Group” of upper Cretaceous age (Pirgua and Balbuena Subgroup).
The carrier unit is base bed, on top of which is mineralised lenticular levels, whose power ranges from 0.90 to 18 meters. The estimated average power is 10 meters. The deposit is located on the eastern flank of an anticline failed.
