Casablanca Mining Constitutes Majority of Mining Claims at Casuto, Its Flagship Gold Property in Chile
SAN DIEGO--(BUSINESS WIRE)-- CASABLANCA MINING (OTCQX: CUAU) announced today that its wholly-owned subsidiary, Santa Teresa Minerals, S.A., has completed constituting a majority of its mining claims at its Casuto Gold Property ("the Property"). The Property is located in IV Region Coquimbo, Choapa Province, Chile. The property is situated 20 km north of the city of Los Vilos, 215 km south of the city of Coquimbo-La Serena and 195 km northwest of the city of Santiago, the capital of Chile. The Property is readily accessible from the city of Coquimbo-La Serena or the city of Los Vilos.
There are 2 types of mining claims, exploration (searching in small amounts) and exploitation (5,000 cubic meters per month initially and above 5,000 cubic meters per month after permits are approved). Constitution is the final process in perfecting mining claims in Chile. It is the goal of the company to have 100% of its Casuto claims constituted for exploitation in 2013. Here is a breakdown of the exploitation and exploration claims Santa Teresa has constituted or pending constitution at Casuto:
Constituted Exploitation Claims (900 hectares in total)
Tauros 1-5 are constituted and Tauro 6 is manifested and pending constitution.
Los Azules 1-3 are constituted.
8/9 of the claims covering 900 hectares are fully constituted for exploitation (this means 8 X 5,000 c/m per month = 40,000 c/m per month immediately after property access rights are completed).
11 Chipi claims are already manifested for exploitation and are pending constitution.
11 Chipi claims are in the process of being manifested for exploitation.
Constituted Exploration Claims (5,300 hectares in total)
22 Chipi claims are all fully constituted for exploration.
43-101 Technical Report on Casuto:
The 43-101 report work was conducted under the supervision of Michael Thompson, HBSc, P.Geo. and Caitlin Jeffs, HSBc, P.Geo. of Fladgate Exploration and is detailed in a National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") technical report on the Property entitled "Independent Technical Report Casuto Project IV Region Coquimbo, Chile (the "Technical Report"). The complete Technical Report is available at:
The Casuto Project is comprised of 22 contiguous exploration concessions or "pedimentos" totaling 6,200 hectares. All concessions are registered in the name of, and owned 100% by, Santa Teresa Minerals S.A., a 100% owned and subsidiary of Casablanca Mining. The deposit is thought to extend through the valley and into Chigualoco Bay for a total length of approximately 13km. Abundant historic pits, shafts and underground workings are evidence of the historical exploitation on the project. The historic workings cover approximately 4km of the 13km long valley.
There are two gold bearing units on the Casuto Project, the higher grade cirque and the lower grade alluvial sediments. The cirque is a gold rich layer where fine gold particles have collected in cracks and pits on the surface of the bedrock. The Casuto alluvial sediments are located in the Casuto-Chigualoco River basin and estuary and on glacial river terraces all deposited through a series of erosive events. The Casuto-Chigualoco River basin and estuary has been protected from sea tides through the evolution of the river and this has created a basin where gold, being carried by the river, has been deposited instead of being carried out to sea. The source of the gold is thought to be high grade gold veins in the surrounding intrusive rocks of Jurassic age.
From 1836 to 1846, the population of the Casuto area reached 6,000 workers and had a town with more than 40 stores and trading houses. No formal records can be found stating how much gold was produced during this time, but verbal history say that daily production was between 11 and 22 kg of gold. The Casuto gold boom lasted until 1846 and then began to slow down. Two things contributed to the decline in production in the area. Sediments were being taken from shafts sunk into thick sedimentary units and many of the shafts were reaching the water table making exploitation difficult.
Monge's Memorandum on Mining Claims Held: Compania Minera Casuto indicates that numerous small operators mined in the Casuto area between 1900 and 1950. These operations were not large and reports indicate grades between 1g/m3 and 4.2g/m3. Operations were difficult due to scarcity of water. The largest operation reported during this time was in 1906 when an English engineer named William Murray formed a company to work the Casuto deposit. Murray's company dug 1200 pits with depths between 3 and 5m without reaching bedrock. The average grade reported from these pits was 4.2 g/m3 (Consultores Geologicos Asociados, 2010).
In 1980 a preliminary study was performed on the Casuto area over a period of 15 days. Two crews of two men collected a total of 940 soil samples during this period. No sample locations or sample descriptions were recorded for these 940 samples, but a report states that results showed between 8 and 15g/t gold (Honour, 1980). The area covered during this study included the Casuto-Chigualoco River basin and the mountains surrounding the basin.
In early 2010 Consultores Geológicos Asociado took five alluvial samples on the property. Samples were taken and washed in a sluice box to concentrate heavy particles. The heavy particle concentrate was then sent to CIMM laboratories in Santiago for analysis of gold content. Results of this analysis show alluvial gold concentration ranging from 0.514g/m3 to 0.650g/m3 gold.
Juan Carlos Camus, CEO, said, "Casuto has historically been one of the largest gold properties in Chile. We are continuing our exploration of the property and intend to pursue additional drilling programs to demonstrate the potential value of the property."
