Report on EL 3491 Cox Peninsula NT.

Abstract

Samples of weathered pegmatite and alluvium were collected from auger drill holes and backhoe trench samples. Samples were collected at 1.5m intervals from auger drill boles and stored in plastic bags. Aluminium tags stapled to the bags designated the hole coordinates and the interval sampled. Generally the drill boles were continued until the drill bit could no longer penetrate or if unfavourable rock units were encountered the was abandoned. Often veins of quartz would halt penetration of the drill. Each hole was geologically logged. The visible mineral assemblage was noted, the clay content, the consistency of the clay (its stickiness), the moisture content, colour, degree of weathering and the interval designated a rock type. The trenches were channel sampled and logged. Approximately 10 litres of sample was collected from each interval. Care was taken in digging and the sampling of the trenches to get below the enriched eluvial zone. All samples were hauled to a central processing facility by the main camp site.
