Heritage Cases

 DESCRIPTION OF PLANNED NON-INVASIVE ACTIVITIES: PHASE 1: Field Mapping - This method includes the identification of quartz veins, often bounding sinkholes, through aerial photo interpretation, satellite image interpretation, ground mapping of surface depressions and vegetation types as they are often indicative - 6 months for Phase 1. PHASE3: Geophysical survey (Magnetic Survey) - Magnetic geophysical surveys will be conducted over selected target areas on a 40m x 20m grid using a magnetometer. Ground magnetic measurements are usually made with portable instruments at regular intervals along more or less straight and parallel lines which cover the survey area. Often the interval between measurement locations (stations) along the lines is less than the spacing between lines. The magnetometer is a sensitive instrument that is used to map spatial variations in the earth's magnetic field. In the proton magnetometer, a magnetic field, which is not parallel to the earth's field, is applied to a fluid rich in protons causing them to partly align with this artificial field. When the controlled field is removed, the protons process toward realignment with the earth's field at a frequency which depends on the intensity of the earth's field. By measuring this precession frequency, the total intensity of the field can be determined. The physical basis for several other magnetometers, such as the cesium or rubidium-vapor magnetometers, is similarly founded in a fundamental physical constant. The optically pumped magnetometers have increased sensitivity and shorter cycle times (as small as 0.04 s) making them particularly useful in airborne applications - 6 months for Phase 3.  DESCRIPTION OF PLANNED INVASIVE ACTIVITIES: PHASE 2: Geochemical survey - Following the mapping various geochemical sampling programs such as whole rock, soil and or stream sediment sampling might be considered to outline potential mineralized areas. These samples are normally analyzed by doing 50g nominal weight (pulverized sample) fire assay for diamonds - 6 months for phase 2. PHASE 4: Areas where surveys showed potential small test pits of 2m x 2 m x 4 m deep will be taken to get samples of the kimberlite to be analyzed in the laboratory. These test pits will be taken with an excavator, and it is envisaged that 250 test pits will be taken on the area confirmed by the surveys. If these areas do show potential in kimberlite deeper drilling holes will be performed - 18 months for Phase 4. PHASE 5: Reverse Circulation Drilling Method - Using a variety of drilling rigs such as truck or trailer mounted, rods and hammers, the ore body can be evaluated by drilling intersecting holes at locations predetermined by the Geologist. Drilling is done in phases, over anomalous target areas, using reconnaissance lines or a grid of 250x250m depending on the level of confidence in the targets and the level of information required. The holes will be approximately 10 - 30m metres deep (average 20m) depending on local depth of the sand. It is envisaged that 20 boreholes will be drilled. Surface area disturbace by drill rig = 1,5 m x 1m. Thus 0,03 ha in total for 20 boreholes.
