Geology Comments

Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The occurence is underlain by volcanic rocks and metasediments. The metavolcanics range in composition from mafic flows, some of which are pillowed, to intermediate tuffs. These units generally strike northeast-southwest and dip vertically. The metasediments consist of an interlayered sequence of greywackes, thin units of chert, marble and iron formation. The occurrence is located on the northern flank of a northeast-southwest trending syncline. The quartz vein which carries anomalous gold values is located in the metasediments. DEPOSIT DESCRIPTION: A small quartz vein has been traced along strike for 150 m. The vein strikes east-northeast and although only an inch or two wide for most of its length, has a width of 24 inches in one of the pits. Small amounts of sulphides occur along the vein.

Dec 07, 2005 (K R Kettles) - MDI1 DATA: GRADE 1936 TRENCH: AS HIGH AS 2.38 OPT AU ACROSS 31 AND 62 CM, VG REPORTED IN VEIN, GRADE 1977 OLD PIT: VISIBLE GOLD AND SULPHIDES NOTICED A small quartz vein has been traced along strike for 150 m. The vein strikes east-northeast and although only an inch or two wide for most of its length, has a width of 24 inches in one of the pits. Small amounts of sulphides occur along the vein. Visible gold has been reported in the veins, and samples across widths of 31 and 62 cm have assayed as high as 2.38 oz/ton (81.598 g/tonne) Au.
