Wandry Well Project

P 31/1701-1706 (Birimian Gold 100%)

Introduction

The Wandry Well project is composed of six prospecting licenses, namely P 31/1701-1706, which cover a total area of 1010 hectares. The project lies less than two kilometres to the northwest of the historical gold mining centre of Yerilla. (see Figure B and 8.1).

Location & Access

The Wandry Well tenements are located approximately 640 kilometres to the northeast of Perth and 150 kilometres to the north of Kalgoorlie (see Figure B). Access to the project is gained via the Kookynie-Yerilla Road, which crosses the southern project area, and then pastoral station tracks within the project area.

Previous Exploration

Exploration at Wandry Well focused on nickel-copper exploration in the 1960s & 1970s. Cominco Exploration Pty Ltd explored the area between 1968 and 1973, however their work programme was limited to geological mapping and general prospecting. Australian Selection Pty Ltd operated a large regional project area between 1966 and 1971 that covered 75 kilometres of strike and was centred on Yerilla mining centre. Exploration included geophysics, rock chipping, surface geochemistry and limited drilling. A limited soil sampling programme covers the tenement area, but an evaluation of the regolith shows that this soil sampling was most likely to be ineffective due a blanket of alluvial/colluvial cover.

Regional exploration for gold was conducted during the 1980s, however it was not until the early 1990s that the Yerilla area was again the subject of serious exploration. CRA Exploration Pty Ltd operated their Raeside project from 1992 to 1997 and primarily explored for nickel and copper mineralisation. Unfortunately much of this exploration, which includes RAB drilling, is not within the project area, however drilling along strike from the project area did achieve a number of anomalous nickel and PGE results, including values of 0.07 ppm Pt+Pd and up to 0.16% Ni.

Mt Kersey NL explored the project area for gold mineralisation between 1995- 1996; exploration included RAB drilling. This drilling was targeted 'Lady Bountiful' type channel gold deposits and consisted of a short programme of fifteen RAB holes in the southern project area. These holes were poorly targeted and assayed for gold and arsenic only, however they did help to define the stratigraphy within the project area (see Figure 8.2).

Geoglogical Settings

Regional Geology

The Wandry Well project is located in the Northeastern Goldfields of Western Australia and covers an area within the southeastern quadrant of the Yerilla 1:100 000 GSWA mapsheet. Regionally the geology of this section of the map sheet consists of a basement of Archaean granites in the west, that are in turn overlain by a sequence of mafic basalts and dolerites, with some sedimentary and ultramafic units.

Prospect Geology

A veneer of colluvium & alluvium covers the project area, with minor sub to outcrop of the underlying stratigraphy. The Wandry Well tenements overlie the contact between the basement granites in the west and the stratigraphy of the northern Kurnalpi greenstone belt in the east. The greenstone sequence striking into the tenement area is interpreted to be an intelayered sequence of ultramafic, basaltic units and volcanoclastic sediments (see Figure 8.2)

Mineralisation & Resource Potential

The project area lies less than two kilometres to the west of the historical Yerilla mining area This area produced in excess of 14 800 ounces of gold between 1897 and 1915. Recent exploration within the region has been successful in defining new deposits, such as CRA Exploration Pty Ltd's 'Bull Terrier' deposit (416 000t @ 2.07 gpt Au), which lies to the southeast of the project area.

The aim of Birimian Gold will be to test the project area for shear hosted gold deposits and komatiite hosted nickel sulphide deposits.
