Lots on the tale
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.
Exploration Plan
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.
Nevada: The Bruner Project
The Bruner project is comprised of 98 unpatented and 21 patented mining claims covering a total of ~2100 acres. The project is located in central Nevada near the Paradise Peak Mine (15 miles south), Round Mountain Mine about 45 miles southeast and the Rawhide mine about 25 miles west. Historic production includes approximately 100,000 ounces at an average grade of 0.56 opt gold.
Historic work by Morrison-Knudsen, Miramar, Glamis, Newmont, Kennecott and others identified a low-grade resource near the center of the property. The work by Newmont, Kennecott and Miramar was summarized in a report by John Schilling in 1991. The resource section of the report identifies approximately 383,000 ounces of gold within the January-Duluth area of the project (this is not a NI 43-101 defined resource). Since that time an additional 75 holes have been drilled within and along strike of the resource area. There has been no definitive report of resources since the 1991 report.
The above historic low grade resource is complemented by a recently discovered high grade vein east of the historic Penelas Mine, which produced most of the 100,000 tons grading 0.56 opt gold on the property. Canamex’s focus will be on quantifying this high grade vein system at Penelas and Penelas East, while evaluating the potential to expand and increase the historic low-grade resource on the property located to the west of the high grade veins.

Bruner Historic 3D Model
We have developed an initial 3D visualization model of the historical resource area at the Bruner Project. The Bruner Historic Model portrays the grade distribution in the historic drilling area where we have more than 40 drill holes into the deposit.
In the video you will first see a rotating overview of the deposit area from the air (brown surface pattern) with the drill hole collar locations shown and the higher-grade intercepts projecting up through the surface from beneath. The model will then slowly rotate downward such that the viewer is taken below the surface (underground) and is looking sideways at the deposit area as the model rotates around the deposit. The effect is as if you were holding the deposit in your hand and rotating it to see it from all angles.
The use of this method is very helpful in identifying trends in the deposit, places where there are insufficient data and where additional drill holes are needed within the deposit areas to connect zones of higher grade, and where there may be undrilled extensions to the deposits.
We will be refining this model as we become more familiar with the capabilities of the program and as we add data through receipt of drilling results from the 2011-2012 drilling program. Also, we will be applying this modeling technique to the exploration target areas and as we get sufficient drill hole data to apply the visualization methods we will post those to the web also.
The colored shells in the model reflect the following grade boundaries:
Orange: + 0.058 opt Au (+2 ppm Au)
Green: +0.0234 to 0.058 opt Au (0.8-2 ppm Au)
Blue: +0.009 to 0.0234 opt Au (0.3 -0.8 ppm Au)
These are grade intervals that are expected to be significant as we continue to evaluate the deposit area in order to bring the historic resource up to modern reporting standards in accordance with NI 43-101.
A qualified person has not done sufficient work to classify the historical resource as current mineral resources or mineral reserves and Canamex Resources is not treating the historical resource as current mineral resources or mineral reserves.
