Dec 07, 2005 (A Wilson) - Supracrustal rocks in the immediate Goudreau-Lochalsh district consist of cycle 2 felsic to intermediate, pyroclastic metavolcanics which are capped by pyrite-bearing ironstone. To the north are pillowed , massive and schistose, mafic to intermediate metavolcanics and minor intercalations of mafic pyroclastic rocks of cycle 3. Several medium to coarse grained quartz dioritie to dioritie sills and/or dikes intrude all of the metavolcanic rocks. Along the northern margin of the supracrustal sequence, separating cycle 3 mafic metavolcanic rocks from the external granitoids, are thinly-bedded metasedimentary rocks with iminor intercalations of chert-magnetite ironstone. The Cradle Lakes Deformation Zone is at least 5 km in length and rouchly 1-2 km wide, but may be up to 10 km in total length. The CLDZ is subparalle to stratigraphy and occurs largely within fedlspar-crystal tuffs, which in many places are difficult to distinguish fromthe cradle Lakes stock, a feldspar porphyry intrusion adjacent to and partially within the CLDZ. The CLDZ contains a large, east-striking high stain zone that is up to 40 m wide and has been traced for several hundred metres along strike.

Dec 07, 2005 (A Wilson) - Several small quartz veins are located within andesite and diabase.
Dec 07, 2005 (A Wilson) - Assays reported by Leitch Gold Mines in 1945 were $2.40, $1.10 and trace gold. Assays from grab samples collected by International Corona returned disappointing values.
