Heron Resources G2 Lens Delivers Strong Metallurgical Results

Heron Resources has announced that results from a metallurgical test work program undertaken on the shallow G2 Lens at its Woodlawn zinc-copper project in New South Wales, Australia. The G2 Lens represents the first mineralization to be accessed in the underground operation and is not currently reported within the operations Ore Reserves.

Mr Wayne Taylor managing director of Heron Resources said that “The results demonstrate that a significantly better concentrate product quality can be produced at higher recoveries in most cases when compared to the assumptions applied in the Woodlawn feasibility study. All three mineralization styles performed extremely well and, while of very limited tonnage, the precious metal levels in the G2HW copper and lead concentrates were particularly exciting. We are looking to target an expansion to the G2 and G2HW mineralization in the expanded drilling program that is currently underway.”

G2 Lens Metallurgical Test Work
The shallow position of the G2 Lens has resulted in this area becoming a focus for recent exploration activity. The first concerted phase of work in 2017 resulted in the reporting of an initial Mineral Resource for this area. The first phase of work did not close off the lens to the south and the initial drill holes in the second phase intersected strong mineralisation in both the G2 and G2HW. While the G2 Lens is currently of limited tonnage, it represents the likely first production source for the underground operation. A metallurgical testwork program was undertaken to assess processing performance and the resulting zinc, copper and lead concentrate qualities. Diamond drill core from this area has resulted in the identification of three different mineralisation styles-polymetallic containing high grade precious metals; polymetallic and zinc stringer;and copper mineralisation.

Drill core samples were composited to provide representative samples of the expected run-of-mine ore for each of the three mineralisation types. Testwork program design started with the standard flotation reagent regime used in the Feasibility Study and involved further optimisation tests. The testwork was carried out at AMML laboratories in Gosford, NSW. AMML have provided metallurgical services for Heron since the Company’s involvement in the project, and have considerable experience with flotation of mineral concentrates.
