Heron Identifies High-Potential Drill Targets Adjacent to Woodlawn Mine

Heron Resources Limited (ASX: HRR) has announced highly positive results of IP geophysical survey at its Woodlawn Zinc-Copper Project, located 250km south-west of Sydney, New South Wales, Australia.

The company reported that the recently completed IP survey has delineated a number of significant IP anomalies, with two key targets at Murphy’s prospect and at Bucklands North prospect.

It may be noted that these anomalies lie on Heron’s granted mining lease and within 2.5km of the Woodlawn plant site, currently being commissioned. HRR reported that the targets will be drill tested in the coming weeks.

Woodlawn Zinc – Copper Project

Heron’s 100%-owned Woodlawn Zinc-Copper Project is located 250km southwest of Sydney, New South Wales, Australia.  The Feasibility Study for the Starter Case of the Woodlawn Project envisages an initial 9.3-year Reserves-based mine life and contemplates campaign treatment processing of 1.0-1.5Mtpa from two separate production sources – underground and tailings.

The production of base metal concentrates is due to commence imminently, which places the Company on track to participate in the pricing environment supported by a strong zinc physical market.

IP Survey

HRR’s program consisted of a modern Induced Polarisation (IP) survey within Heron’s granted mining lease and covers an area of 4.0km x 2.4km directly north of the Woodlawn Mine. This area contains the Woodlawn volcanogenic massive sulphide (VMS) host rocks.

The survey was aimed at identifying anomalies at depth that could be related to potential new Woodlawn style deposits. The survey lines were spaced at 400m with some infill in the south to 200m. The survey recorded chargeability, conductivity, and magneto telluric data which was collected on 2D lines and then modelled in 3D.

Significant IP Anomalies Delineated

The company reported that the large area IP survey has delineated a number of significant IP anomalies, with two key targets; coincident chargeability and conductivity anomaly at Murphy’s prospect, and large chargeability anomaly at Bucklands North prospect.

HRR said that the anomaly at Murphy’s prospect is a strong coincident chargeability and conductivity anomaly extending down 600-800 m below the surface and covering a strike extent of some 600 m. Meanwhile, at the Bucklands North prospect, a large, strong chargeability anomaly has been identified over some 600 m of strike.

Drill Follow Up

Heron said that the two main IP anomalies at the Murphy’s and Bucklands North prospects have been selected for immediate drill follow-up. A proposed 780 m deep drill hole is being planned to provide an initial test of Murphy’s anomaly while a proposed 750 m deep drill hole has been planned to provide an initial test of Bucklands North prospect anomaly.

Although the anomalies at Bucklands (directly north-west of the Woodlawn pit) and the Western prospect also warrant follow-up drilling, the company has prioritised them below the two initial anomalies.

The company said that the drill program is in the final stages of planning with drilling expected to commence in the next few weeks.

CEO Statement

Heron’s Managing Director and CEO, Mr. Wayne Taylor said: “Our exploration team is focusing on the area around the Woodlawn Mine with the specific aim of discovering a new Woodlawn-style deposit.

Modern geophysical techniques are ideally suited for this style of mineralisation and this IP survey has generated some of the most exciting responses since the discovery of the Kate Lens electro-magnetic anomaly. We look forward to mobilizing a drilling rig in the coming weeks to drill test these anomalies.”
