Project Management

Minera Camargo is well-equipped to manage and execute projects from the conceptual stage through target selection, staking and land acquisition, surface surveys to exploration drilling and development. We have a modern office with state-of-the art computing and plotting facilities, three off-road vehicles, and storage facilities for exploration equipment and samples at a ranch near our office. We have access to trained prospectors, national and expatriate geologists, geophysical contractors and all of the other personnel required for a successful exploration program.

Concept

The conceptual stage of exploration involves applying appropriate ore genesis models to specific areas of interest for a marketable commodity. For example, Minera Camargo started exploring the calderas in the Ignimbrite Belt of the Sierra Madre Occidental for gold and silver in 1997. Specifically, the calderas represent collapsed volcanic centers, or heat engines, which circulated gold and silver-bearing fluids through fractured rocks. Today, these fractures are preserved as gold and silver bearing quartz veins, stockworks and disseminations

Data Compilation

Example of COREMI Geological-Mining map.

Mexico has well-developed geographical (INEGI) and geological (COREMI) survey branches. Geographical maps both in raster and vector format are available from INEGI. Geological-mining maps at 1:50 000 and 1: 250 000 scale are available from COREMI. They also have satellite coverage of Mexico, magnetic data from airborne surveys, regional stream sediment geochemical surveys and detailed surveys of most of the known showing areas in Mexico. All of Minera Camargo's concept evaluations start with a review of the existing data from INEGI and COREMI, as well as data from other sources

Target Selection

When the exploration data supports the concept, a valid exploration target has been defined. For example, the Bramador Mining District in Jalisco is known to have several Kuroko-type volcanogenic massive sulfide (VMS) deposits. Regional stream sediment geochemistry suggests that the massive sulfide horizon extends beyond the known showing areas.

Minera Camargo evaluated the data for International Croesus Ventures Corp. (ICU), and our interpretation of the geological and geochemical data shows that much of the VMS potential of the Bramador District may be controlled by the down-plunge axis of the Bramador Syncline

Staking and Land Acquisition

Example of "Trabajos Periciales" for one of the properties staked by Minera Camargo.

Exploration Targets that merit additional work can be acquired either by staking or negotiating with the owner. As staking is the most secure, and cheapest form of Mineral Tenure, Minera Camargo prefers to make property acquisitions that way. See our section on "Mineral Land Tenure" for more information on staking claims in Mexico

Surface Surveys (e.g. Geochemistry, Mapping)

Exploration capital at the beginning of a new venture is valuable, and Camargo crews are conscientious about being as efficient as possible with their exploration. We always try to establish a camp as close as possible to the site under investigation, and enlist a local crew. As the local people usually know where the mineral showings are, enlisting their help and support from the beginning is strategically important to the overall success of a new project.

Sometimes our mapping has had surprising results. For example, the Ignimbrite Belt of Mexico is widely advertised as consisting of dominantly andesitic rocks of pre-Eocene age, and younger (Oligocene to Miocene) rhyolite ash-flow tuffs. In fact, the Eocene and older rocks have a very high proportion of rhyolitic flow-dome complexes and ash-flow tuffs.

Development

Aspects of project development include permitting, negotiating land access from the local owners, building access routes, exploration drilling and sometimes underground development.

Minera Camargo has been doing advanced exploration of the Picachos Property with RNC Gold Inc. since 2002.
