Guyana: The Aranka North Project
General Geology of Guyana
Guyana hosts one of the largest and most undeveloped gold provinces known in the world. Geologists recognize it as the western half of the west African gold belt that was rifted away from the African continent with the opening of the Atlantic Ocean and the separation of the South American continent from the African continent. Combined these two gold provinces host in excess of 180 million ounces of gold in known deposits, with +80 million ounces of that on the South American continent and at least 20 million ounces of gold in undeveloped deposits in Guyana.
The gold provinces occur within Precambrian aged granite-greenstone belts, with individual gold deposits occurring in shear zones similar in nature to shear-zone hosted gold deposits of the Canadian shield, in granitic, meta-volcanic, and meta-sedimentary rocks. One of the attractions to this gold province is there does not appear to be a single unique geologic setting for the occurrence of multi-million ounce gold deposits. This suggests the opportunity is wide open for discovery of additional world-class gold deposits in a number of geologic settings. Reinforcing this is the widespread occurrence of alluvial (placer) gold deposits and occurrences across Guyana, production from which generates in aggregate in excess of 300,000 ounces of reported gold production annually. Alluvial gold deposits tend to be in proximity to the bedrock source that generated the alluvial gold in gravels shed off of the bedrock terrain.
Toroparu-Aurora-Sulfur Rose Gold Trend
One of the most pronounced and productive gold trends in Guyana is the northeasterly alignment of the Toroparu (+7 million ounces), Aurora (+6 million ounces) and Sulfur Rose-Aranka (+1 million ounces) gold deposits. This trend alone hosts +14 million ounces of gold or approximately 70% of the quantified bedrock gold deposits currently known in Guyana. The Aranka North Project lies along this trend to the northeast of the known gold deposits, where this gold trend intersects a NW alignment of known gold deposits. It is the intersection of these two structural trends that establishes the Aranka North project area as an exciting exploration opportunity for hosting a major bedrock gold deposit.
Aranka North Property Geology
The Aranka North property consists in general of granite-greenstone terrain, with granitic terrain comprising the northern portion of the property and with meta-volcanic and meta-sedimentary belts comprising the southern portion of the property. Regional aeromagnetic surveys flown previously identify several long aeromagnetic lows that are potentially indicative of intensely altered meta-volcanic and meta-sedimentary rocks which are typical of the host terrain for large gold deposits. These magnetic anomalies are in excess of ten kilometers long each.
Canamex Guyana Inc. is in the processing of staffing up to commence a field program for the upcoming dry season commencing in August and lasting through November (in general). GMV Minerals Inc. flew the property for follow-up geophysical aeromagnetic and radiometric data. Canamex will acquire these data from GMV Minerals, complete the processing of the data, and interpret the data with respect to both aeromagnetic low targets and radiometric high targets, both of which tend to be indicative of mineralized zones within the granite-greenstone terrain.
The field program will consist of confirming access and alluvial mining locations, which in general are undocumented and need to be mapped, and any geologic characteristics that can be gleaned from the open cuts created by the alluvial miners, and regional geology. If ground geophysical crews are available in country we may follow up the high priority airborne anomalies with ground surveys yet this fall, and with stream sediment and soil sampling surveys to define the possible source drainages of the alluvial gold occurrences.
