The SSW Probe developed by Instrumentation GDD Inc. It reduces dilution and increases ore grade within mining operation.

Several mines use the GDD SSW probe to log nickel, copper and iron sulphides in blast holes. By lowering the probe in the blast hole, a profile of the electromagnetic (EM) response is measured and obtained in real time making it useful for finding out ores content. Indeed, logged drill holes in nickel mines have demonstrated that ores content of nickel, cobalt, copper, and PGM are often proportional to the intensity of the probe EM response. Quick and inexpensive, probing a 30 m depth blast hole within 10 cm intervals will take less than 2 minutes.

Surveying a drill hole with a GDD SSW probe helps to determine the shape of the high-grade ore body within the waste rock and low grade ore. Using this tool, user will know exactly where to stop blasting thus saving time and money. The SSW probe can also be used to discover and mine pockets of rich ore that are otherwise left in place. Increase ore grade at the mill and get rid of the waste!

The 2009 Exploration Program at the MAN, Alaska project included a new ZTEM airborne survey (Z axis Tipper Electromagnetic system), extensive geological mapping and a proprietary fluxgate time domain ground EM surveys (full waveform streaming multi sensor fluxgate array).  The 2009 geophysical programs (ground fluxgate TEM, ZTEM, and BHEM) were considered a great success.  These very compelling geophysical targets, are the best discovered to date on the MAN property and the foundation for a productive 2010 exploration program.

3D inversions of aeromagnetic data, as well as several widely spaced deep drill holes show a consistent presence of abnormally thick ultramafic bodies with localized deep feeders. Last year’s results add to the evidence that the MAN property is the main intrusive centre for Triassic magmatism that generate the extensive nickel, copper and PGE (platinum group elements) bearing ultramafic intrusions and coeval lavas within the Alaska, Yukon and BC, segments of the Wrangelia terrain.  Drill results to date come from the holes targeted using the proprietary ground time domain EM survey (TEM), in conjunction with the new ZTEM airborne survey and previous ground gravity and VTEM airborne surveys.

Interpretation of the 2009 MAN drilling results assays indicates the presence of a disseminated NI-Cu PGE (platinum group elements) concentration build up extends beyond 600 meters in DDH PNI-09-024 and over 1000 meters in DDH PNI-09-025.  Geophysical surveys show that these conductive bodies are associated with the strongest Fluxgate TEM anomalies on the property,  in addition, strong responses to the BHEM surveys indicates late channel (high conductance channels) conductivity build up beneath the drill holes.

The surveys described below were used to model the interpretation of conductive anomalies on the property. The analysis concludes that the anomalies are deep, large and very compelling.

1. ZTEM Survey – has for the first time identified at depth the shape structure, and conductive zones of the mafic and ultramafic intrusions.
2. Ground TEM – proprietary long time constant, time domain electromagnetic surveys allowed for deep search (> 800 meters) for high conductance bodies commonly associated with Ni-Cu sulphides that have been missed by previous surveys methodologies.
3. Ground and Airborne Magnetic Survey’s - these survey’s help to define the magnetic bodies below surface that often correlate to the ultramafics and mafic rocks on the property.  In addition, UBC 3D inversions and Euler 3D inversions are employed to help determine the location of the form, internal structure, and deep kneels or feeder dykes associated with the intrusive bodies.
4. BHEM Survey – a borehole electromagnetic survey is performed down the drill hole to detect conductive anomalies within, beside and below the drill hole to aid in the correlation with the new high priority, long time constant, surface TEM survey results constraining more accurate location of the conductor.

One of the most exciting targets from the 2009 geophysical program was the identification of the location for drill-hole PNI-09-025 based on the initial results from the TEM surveys.  The hole was drilled to a depth of 1066 metres and terminated due to the limitations of the drill.  The BHEM (down hole geophysical survey) showed an increasingly large response towards an anomaly below the hole’s final depth.

Low-frequency borehole electromagnetic surveys (BHEM) were carried out in five of the 2009 drill holes, as well as seven older drill holes. A number of moderate to strong off-hole conductors were detected and are being evaluated as follow-up drill targets for the 2010 program. Three holes (07-001, 09-023 and 09-025) show anomalous increases in late time channels indicative of deep conductors below the base of the holes. These deep conductive zones correlate with high-priority long time-constant surface TEM anomalies.

Extensive geophysical work was conducted concurrent to the drilling program.  In particular, a new ground time domain EM system (full waveform streaming multisensor fluxgate array), was deployed extensively through the latter half of the exploration season.  This was the first instance of this technology being used in North American nickel exploration.  This ground based EM technology developed by Dr. Mark Shore (Magma Geosciences Inc.) provided Pure Nickel exploration team with the ability to collect low-noise late time data under challenging conditions and identify electromagnetic anomalies at greater than  800 metres depth.

Dr. Mark Shore is going to represent example of using of lower frequencies induction coil, SQUID and fluxgate sensors on the nearest PDAC in Toronto: http://www.pdac.ca/pdac/conv/2010/pdf/presentations/ts-mark-shore.pdf.

Instrumentation GDD Inc. (Quebec) announces its newest breakthrough in the field of geophysics with the Sample Core IP Tester, model Time Domain Low Voltage.
Made after the GDD IP Receiver, model GRx8-32, this new geophysical instrument is perfect for determining a core sample resistive properties. Tests done with the SCIP will determine the chargeability and resistivity of the diamond drill core or field. Knowing what are the physical properties of your sulfites, will help you plan the appropriate geophysical survey. Rugged, compact, inexpensive and easy to operate, the SCIP is built like a 1 dipole GDD IP Receiver.

GOLDEN, COLORADO — 12/03/09 — Lake Victoria Mining Company reports about the acquisition of its own Induced Polarization (I.P.) electrical geophysical prospecting system that will initially be used to target drill holes at the Company’s Singida gold project in central Tanzania.

At Singida, geologic mapping, underground sampling, trenching and detailed ground based magnetic surveys have defined a five kilometer long gold bearing quartz vein system. The Company is currently field surveying and clearing grid lines for conducting electrical I.P. surveys along this five kilometer mineralized trend.

I.P. surveys, by measuring the response from energizing the ground with high energy pulsating electrical forces, can locate at depth the mineralized centers and metal rich source areas which produced the gold veins observed in surface exposures. Locating the source areas and the geologic structures which controlled the near surface vein deposits will allow drill holes to be strategically placed along the five kilometer trend. The objective of the I.P. surveys is to locate drill targets and the objective of drilling is to rigorously define gold resources and reserves that are capable of supporting an economic mining operation.

Roger Newell, president of Lake Victoria said: “Having our own I.P. equipment will allow us to plan and execute our own surveys in a timely fashion. Last year we purchased our own state-of-the-art ground magnetic equipment; now having both geophysical systems will allow us to conduct ground magnetic and electrical surveys quickly and accurately and shorten the time to begin drilling. The sooner we can drill, the sooner we can advance the project towards engineering studies and production.”
