Abstract

This report provides a summary of the work programs conducted by mineral exploration companies within the Dunolly 1:100 000 map sheet area (DUNOLLY) since the introduction of the Exploration Licensing (EL) system in 1965. Since that time, approximately 107 licences have been granted within the area. This report provides summaries of the exploration conducted in each EL including stream sediment, soil and rock chip geochemical, geophysical and drilling data.

The tables and maps in this report provide further information on the DUNOLLY licences. Tables include details of the geochemical and drilling programs undertaken within the EL's, principal exploration targets, the time period the licences were held for and actual expenditure levels for each EL. Maps showing the positions of the EL boundaries and areas where major work has taken place are also included.

Since its discovery in 1852 around 53 tonnes of gold has been extracted from DUNOLLY, 61% from hard rock quartz reef deposits and 39% from alluvial deposits (Maher, 1996). The "old timers" did not extract all of the gold and the area remains highly prospective for gold with advanced exploration techniques increasing the chances of discovering a new economic deposit. Modern exploration has targeted gold, molybdenum, and other minerals including copper, silver and uranium. Gold has been the major target for the majority of companies that have worked in the area.

Exploration Licences (EL's) for Gold Province which trends NNW-SSE through which no company reports have been received the area. It contains nine major goldfields; by Minerals and Petroleum Victoria, Wehla, Fenton's Creek, Bealiba, Kingower, Department of Natural Resources and Rheola, McIntyre, Inglewood, Tarnagulla and Environment are denoted as "not submitted" Dunolly.

The drilling tables within this report summarise all drilling conducted (excluding RAB drilling) and outline "significant intersections" from drill logs. A gold cut-off of 0.5 g/t has been used in this report, with values above this deemed to be significant or anomalous and at a level that would trigger interest in a grass roots exploration program and provide evidence to continue exploration in that area. In cases where the company reports do not contain drill logs or there has only been a small amount of drilling completed (only two holes for example) then the results are detailed in the text only.

MINERAL EXPLORATION HISTORY - DUNOLLY 5

2 History of Exploration Exploration and CRA Exploration examined the alluvial leads in the Avoca area, drilling along lines across the Avoca River with moderate 2.1 Gold success (EL 646).

Gold in DUNOLLY occurs in quartz reefs, In the first half of the 1980's CRA Exploration Tertiary deep leads, shallow alluvial leads and conducted a major investigation of the Loddon high level gravels. Gold bearing ore shoots are and Bet Bet Leads (EL 3000), delineating a developed in the folded turbidites and are potentially large gold resource but failing to characterised by multiple quartz veining find an economic extractive process.

Carpentaria Exploration veins within the sedimentary beds are referred conducted exploration targeting large tonnage to as "cross reefs" or "cross veins". Weathering disseminated gold deposits and placer gold and erosion of these reefs and country rock deposits around the township of Dunolly released enormous amounts of gold which (EL 717). CRA Exploration targeted large resulted in the accumulation of extensive tonnage reef and placer deposits around the alluvial deposits. The gold in the deep and Fenton's Creek area (EL 1173).

deposits is widespread. Prospecting and mining took place at the eastern end of the Mt Moliagul granitic complex during World War 1 (1914 - 1918).

Commencing exploration in 1972, Aquila and Transouth discovered uneconomic disseminated Mo-Cu mineralisation in the aplite and Mo-Cu mineralisation in a stockwork quartz system on the western slope of Mt Moliagul (EL 227). In 1973 Borchers found mineralisation on the upper southern slopes of Mt Moliagul along granite-metasediment contact zones (EL 230). In 1979 Base Exploration, Dampier Mining and BHP Minerals (EL 1199) began exploration for molybdenite mineralisation related to granitic aplite veins. Good intersections were found on the western slopes of Mt Moliagul although the distribution of molybdenite was sporadic.

2.3 Other minerals

Other minerals that have been explored for within DUNOLLY are uranium, copper, silver, lead, tin, nickel, wolframite, antimony and bismuth. Small occurrences of wolframite were reported near Wedderburn in 1915. It occurs within quartz veins in Ordovician schists. It was also reported to occur at Shelbourne. Small occurrences of antimony have been recorded at Havelock and Dunolly. At MacFarlane's Reef small but rich deposits of stibnite associated with gold and quartz were found in veins within Lower Ordovician strata. An isolated uneconomic occurrence of torbernite was located in superficial deposits of ironstone near Mt Kooyoora. The mineral is of secondary origin associated with granite with of U3O8 < 0.01% (Webb, 1970).

During the late 1960's and early 1970's Equity Traders and Mid-East Minerals conducted limited mineral exploration for some of the above minerals associated with the Harcourt acid intrusive without success (EL 128 & 198 respectively). In the early 1980's Essex and CRA Exploration completed limited drilling for uranium encountering some anomalous results in the Three Chains Road area (EL 1247).
