Khongor Project
Project Highlights
Summary
Voyager Resources acquired and commenced drilling on its 100% owned Khongor Copper Gold Porphyry Project in Southern Mongolia during December 2010. Drilling has been encouraging to date, with all holes completed by Voyager intersecting porphyry style copper mineralisation. Drilling is planned to continue after a brief break, with further extensive exploration to commence once warmer conditions permit.
Project Details
Results to date have been promising from Voyager's maiden drilling program at the Khongor Copper Gold Porphyry Project.
Drilling to date has focussed on both infill and step out, with drilling confirming the presence of significant porphyry style primary quartz-chalcopyrite stockwork veins within highly altered siltstones and porphyry dykes. Mineralisation varies from high density stockworks and sheeted veins to lower density but persistent veins and disseminations which occur over substantial downhole intervals. Initial drill core samples have been sent for analysis to SGS laboratory in Ulaanbaatar with gold and copper results expected in late February 2011.
The current drilling area represents just one of several targets within Voyager's exploration license area. A belt of copper mineralisation estimated at greater than one kilometre in length follows steeply dipping faults related to rifting and emplacement of adjacent intrusive stocks. Shattering of the surrounding wall-rocks during intrusion has created excellent pathways for hydrothermal fluid migration and resultant copper gold deposition. Structural interpretation of the drill core has identified a complex geological history and by timing the mineralisation episode it is now possible to understand and predict the general distribution of copper. The present erosion level at Khongor has exposed mineralisation at surface yet there are strong indications that blow-outs of similar mineralisation intensity occur at greater depths adjacent to fault zones.
A combination of porphyritic monzonite intrusions, precursor porphyry dykes, potassic to phyllic alteration zones, diatreme breccia pipes, deep-seated faults and stockwork chalcopyrite-bornite veining all point to a classic porphyry copper-gold system. Modelling of previous drilling assay results also shows a strong correlation between copper and gold.
Given the encouraging preliminary results from drilling to date a program of geophysical and geochemical exploration will follow once warmer conditions permit. Geophysics should allow for 3D modelling of mineralisation at depth and for defining fault zones and intrusions while geochemistry aims to define additional targets and alteration halos.
