BKJV is a wholly owned subsidiary of Ecotech Resources. ML1617 encompasses the Broula King gold mine located and processing facility which is owned by BKJV.

Broula King was mined via an open pit operation by contractors Mitton Bros. Earthmoving using an excavator (initially 25t and later 35t) and two dump trucks. The gold treatment plant at the Broula King mine used carbon-in-leach (CIL) technology and electro-winning from solution. The Broula King gold mine became operational in 2012 and mining concluded on 31 July 2014. The Broula King Project was placed on care and maintenance after the last gold pour in September 2014. BKJV extracted a total of 186,863 tonnes of ore at 2.50g/t gold.

Location & access

EL 8509 is located between Grenfell and Cowra in the Central West Slopes of New South Wales. The sealed Mid-Western Highway between Cowra and Grenfell passes through the Licence. From the highway, most areas within the Licence are accessible from secondary public roads and farm tracks on freehold land.

Geology

Almost all of the mineralisation of interest within the exploration licence occurs within the Wenlockian age (424 - 428ma; late Early Silurian) Illunie Volcanics (Sdi).

The other key geological elements within the licence area include the Young Granodiorite (Syg) which may be coeval with or slightly younger than the Illunie Volcanics; and the Emsian age (late Early Devonian) Broula Granite (Dbg).

There are three major locations that dominate much of the previous exploration within EL 8509. These are:

1. The Broula King gold deposit (ML 1617) and other satellite deposits around Broula King, particularly the Cowfell prospect;

2. The Broula Iron (magnetite) mine (ML 1616); and

3. The Claypit prospect (ML 1559 held for Group 5 minerals).

Although the primary target for EL 8509 is gold and copper, the iron mineralisation is noted and is of interest given its likely genetic association with porphyry, skarn and epithermal AuCu-Ag. The Broula iron mine, given that it is excluded from EL 8509 is of interest only as an example of the style of mineralisation. The Claypit prospect is of interest, but is less likely to be of near-surface economic interest and has had significant exploration in the past without identification of a near surface target.

Historic Tailings

In the early 1900s, two brothers began digging for gold on the ML1617 site. They set up and stamper battery and ore pits and dumped the tailings below it. When World War 1 started, they went off to join the fight in Europe, and never returned. The mine site was abandoned.

In the 1980s and 1990s, BHP and Newcrest both did ran tests on the historical tailings dumps. Both parties concluded there was approximately 30,000 tonnnes at 4g/t Au.

Susbequent tests conducted by Ecotech have concluded a similar grade, between 3.8 to 4g/t Au.

Ecotech saw this as a viable option to reprocess these tailings as the first stage of the project.

Projected gross earnings from this stage are $A20M+.

Broula King Processing Facility

Broula King Gold (CIL) processing facility (currently on “care & maintenance”, is rated at 120,000 tpa with a TSF.)
