Tablachaca: Geology and Minerals

Mineralization
A placer gold deposit occurs in Tablachaca River along the entire property and extends beyond the limits of the concessions. The gold and associated heavy minerals like wolfram are currently recovered by panning and sluicing by people of the neighborhood. Limited sampling of Tablachaca River made by Altai Resources yielded 0.3 gr per cubic metre. The gold recovered by occasional miners has different forms like scales, plates and nuggets.The gold mineralization comes from the hidtothermal gold scattered along the Pallasca – Cabana area.

Local Geology
Locally the property is underlain by river gravel deposits which overlain sediments of the Chicama and Chimu Formations. The thickness of material alluvial has been surveyed by Georadar Method that shows two different layers, the upper consist of gravel poor cemented of 7 metres of thickness while the lower layer of 15 metres thickness is interpreted as consolidated gravel. Along the Tablachaca river several terraces occurs.

Structural Geology
The concessions area is situated on the Eastern flank of the Cordillera Occidental of the Andes.The regional geology consists of rocks of Upper Jurassic and Lower Cretaceous age and consist of black shales of the Chicama Formation, quartzites interbedded with anthracite of the Chimu Formation and limestones, sandstones and shales of the Santa and Carhuaz Formations. These sediments are intruded by intrusive rocks and are unconformably overlain by Lower to Middle Tertiary andesitic to dacitic volcanics of the Callipuy Group.
