The 2Good area is underlain by rock of the Middle Jurassic Duckling Creek Syenite Complex of the Hogem Intrusive Suite.
The Duckling Creek suite of intrusions displays variable potassic and calc-potassic alteration, and alteration mineralogy mimics primary igneous mineralogy. Alteration occurs as weak chlorite alteration and, outside a mineralized centre, as patchy albite-diopside with diopside veins. Potassium-feldspar–epidote alteration is irregularly distributed. Sulphide species occur regionally as pyrite, chalcopyrite, bornite and chalcocite.
Please refer to the Lorraine occurrence (MINFILE 093N 002) for details of the Lorraine-Jajay property that includes the 2Good area.
Work History
In 1991, BP completed geochemical, induced polarization and minor diamond drilling in the area that subsequently known as the 2Good target.
In 2005, Eastfield Resources Ltd reported work on its 2Good target, which is characterized by a 3 kilometre linear induced polarization chargeability anomaly, measuring 600 metres to 1 kilometre wide. Seven drillholes, spaced 500 metres to 1.5 kilometres apart, were completed as a broad test of this feature. It was concluded that the zone is a large, well-developed potassium alteration system associated with the presence of a variety of intrusions including megacrystic syenite porphyry. Most of the holes carry pyrite; copper mineralization was observed locally.
In 2007, Teck Resources Limited carried out an induced polarization geophysical program on a number of sites within the Lorraine-Jajay property. The survey identified a zone of magnetic high underlying the magnetic low that characterizes the Too Good area. The magnetic high was not penetrated by 2005 drilling.
In 2008, Teck Resources Limited conducted a 19-hole drilling program on the Lorraine-Jajay and Jan-Tam-Misty properties. Four holes were drilled on the TooGood claims (L08-116 to L08-119). L08-116 returned 0.12 per cent copper over 46.6 metres. L08-118 returned 0.14 per cent copper over 12 metres. L08-119 returned 0.12 per cent copper over 26.8 metres (Assessment Report 30584).
In 2010, Teck Resources Limited conducted a spectral and lithogeochemical sampling of historical drillcore and soil sampling program on the Too Good and Bishop zones of the Lorraine-Jajay property. Soils were sampled for pH and copper, molybdenum, zinc, lead, and gold with anomalous geochemical results within both sampled zones.
