Abstract
CGG deployed HELITEM, a helicopter-borne time domain electromagnetic (TDEM) system over the Lalor Deposit and other proximal deep conductors of Hudbay Minerals in northern Canada. The Lalor Deposit is ~570 m deep and is a difficult target for airborne EM systems. The system was configured with a dipole moment of up to 1.9 MAm2 at base frequencies of 15 Hz and 30 Hz. The results of this survey have been used to characterise the TDEM response from deep volcanogenic massive sulphide (VMS) deposits within the region. HELITEM is the only airborne controlled source TDEM system to have detected the Lalor Deposit.
