White Ridge prospect annual report mineral claims.

Abstract

The limited exposure over the area is mostly confined to the south of the Great Bear tenements where a quartz ridge striking west north-west and some low hillocks of warramunga group sediments outcrop. The quartz haematite ironstone units at the Trump dip steeply to the south beneath the White Ridge tenements. Gridding and Sampling - The area was gridded by chain and compass on north-south lines 200 m apart, using the northern corner of MCC 225 as an arbitrary datum. Thick scrub prevented the completion of two short lines in the central south part of the claim block. All grids were lag sampled (Carver et. al, 1987) at 25 m spacings, giving a total of 204 samples which were analysed for gold (to ppb levels) copper and bismuth. Results were disappointing, with all elements being uniformly low. Weak anomalism on the northern and north-eastern edges of the grid is attributable to lateral dispersion of material from the nearby Trump and Great Bear mines. Results are plotted on Plans 4910, 4910/1, 4910/2 in the rear pocket. Geophysics - The White Ridge prospect is included in an area flown by Aerodata for detailed magnetics and radiometrics. Line spacing was 200 m and flight height 60 m. Results from this survey have been processed and interpreted by Aerodata. There is no indication of any obvious magnetic targets within the White Ridge block, but several prominent lineaments, that are spatially associated with historic workings nearby, pass through the area. Conclusions and Recommendations - Due to the heavy alluvial cover in some areas it may be more suitable to carry out a soil programme over the claim block, particularly those areas missed during lagging. The area is in a structurally favourable location with known gold occurrences nearby, notably Lone Star and Great Bear. The strike extensions of these mines would pass through the White Ridge tenements.
