A new look at an old headframe - Lynn Lake Camp
Paul Stacey, President & Founder, MapIT
Corazon Mining has acquired the most prospective areas around the old Lynn Lake Mining Centre in Manitoba. A compilation of 70+ years drilling, geophysics and mining data from the Lynn Lake Mining Camp has generated an enormous amount of information. Read more

We will use Geosoft Target to see how Corazon Mining identifies and targets compelling new prospects for more detailed assessment and drilling. If the renewed exploration effort is successful, the existing data and infrastructure provides the opportunity for reduced start-up costs and the rapid progression through development to production.

Continual Improvement: Geophysical Examples, Eagle Ni-Cu Mine, USA
Dick West, Technical Director, Exploration Technology & Group Resources, Lundin Mining Corporation
As explorationists are forced to look deeper and in more challenging geophysical environments, it becomes more important to fine-tune survey methodology so that the maximum knowledge can be extracted from the limited data sets. Read more

Two examples of this continual improvement will be discussed from the Eagle Ni-Cu Mine in Michigan, USA. The high grade Eagle Ni-Cu mine is hosted by an ultramafic Proterozoic magmatic feeder that intruded into the metasediments of the Proterozoic Baraga Basin. There is limited outcrop in the area due to a covering of glacial till and a thick portion of the Baraga Basin is very conductive and magnetic due to pyrrhotitic sediments. The till thickness varies from 0 to over 200 m and complicates the interpretation of gravity survey data. The very conductive metasediments limits the depth of penetration of conventional surface based ground EM surveys and complicates the interpretation and limits the radius of detection of borehole TEM surveys.

The interpretability of borehole TEM surveys wwas improved by significantly lowering the base frequency of the transmitter in order to allow the host response to decay enough that the very conductive, constrained massive sulfide response could be better observed. Complex borehole TEM responses with multiple off-hole type responses became more conventional in nature and the off-hole response of the Eagle mineralization could be detected.

Till thickness had previously been determined by drill hole intercepts and the resonant frequency of passive seismic noise. To extend the coverage of these values, frequency domain data from a Resolve survey was modeled using 1D inversion software over the entire exploration block. Once the till thickness was interpreted, the gravitational response of the till was computed and subtracted from the airborne and ground gravity surveys. This improved the interpretation of the gravity data.

Tuesday, 4:00 PM Booth 931 Using VOXI forward models to support geological interpretations
Joel Jansen, Lead - Geophysics, Anglo American
This presentation will show how to create lithological and petrophysical voxels from geological surfaces and then use VOXI forward modelling to augment the exploration model.
