By measuring density, magnetic susceptibility, acoustic velocity and natural gamma across multiple kimberlites, and associating physical property signatures with the various facies intersected. This greatly improved the understanding of the property and helped focus additional work. Mexico Gold Mine Development Gold Mine Development MEXICO DGI obtained hydrogeological and structural information for the development stage gold program. Alaska Copper - Gold Copper - Gold ALASKA The site is a large-scale, low-grade, high-tonnage copper-gold deposit in Alaska. Part of the deposit is deeply buried, and geophysics can be extremely useful in targeting drillholes. Geophysics is the non-invasive investigation of the subsurface by measuring physical properties contrasts, such as magnetics, gravity, and resistivity from surface. The geophysicist uses these measurements to model the size and depth of the target prior to drilling. The drilling results are analyzed, and sometimes the target is hit, and sometimes the hole missed. Regardless of the outcome, it is important to capture physical properties inside the drillholes. These direct physical property measurements of the geophysical parameter used to originally target the drillhole, are used by the geophysicist to better understand why the target was hit/missed, and help guide where to drill next. DGI helped our Alaskan client with this approach to guide the drilling campaign. Labrador Iron ore Iron ore LABRADOR DGI measured the density and magnetic susceptibility, estimating the quality and tonnage of the iron ore deposit. Gyro measurements were also performed to place the information in the correct location. Minnesota Iron ore Iron ore MINNESOTA DGI supported our iron client with televiewer measurements for lithological characterization, structural analysis and rock mass conditions. Saskatchewan Uranium Uranium SASKATCHEWAN DGI was asked to measure the natural radioactivity and determine rock type, as part of a large scall uranium project. Given the complexity of the terrain, or used a float plane to travel to camp, located on the edge of the lake. North Carolina Lithium Lithium NORTH CAROLINA Our team took televiewer measurements, supporting geotechnical analysis to evaluate re-opening a former mine. DGI also completed a hydrogeological program to measure flow rates for the design of a de-watering program. British Columbia Nickel Nickel BRITISH COLUMBIA DGI performed geotechnical work to understand joint sets and other planes of weakness to support the pit wall design. Physical properties were also collected to support ongoing metallurgical work, to design a flowsheet to maximize recovery of the nickel. Northwest Territories Hydrogeology Northwest Territories NORTHWEST TERRITORIES An active mine was developing a new pit, adjacent to a lake and needed to understand the hydrogeology. The client was also concerned about the potential for swelling clays and their impact. DGI designed a program that included Nuclear Magnetic Resonance (NMR), and Spectral Gamma. NMR, is an MRI
