Project Overview

Sulphur Springs Deposit

A promising copper-rich site with the potential of near term development and further exploration.

The Sulphur Springs project is located 144 km to the south east of Port Hedland and includes the Sulphur Springs and Kangaroo Caves deposits together with tenements along the 27 km Panorama Trend that contains six advanced targets that have returned intersections of commercial grade copper and zinc.

Deposit Morphology

The Sulphur Springs Deposit shows typical VMS morphology with a copper-zinc rich massive sulphide lens underlain by a copper-rich stringer zone up to 50m in width. Mineralisation has been drilled over a strike of approximately 500m and to a depth of approximately 400m below the surface. Drilling below 400m vertical is sparse, offering excellent exploration upside.

Project Overview

VMS Mineral Field Exploration

DEVELOP holds mineral resources totalling 24.4 Mt at 1.2% Cu, 3.5% Zn and 18.7g/t Ag within its Pilbara projects. The company has identified three VMS mineral fields, hosting six known deposits.

VMS (Volcanogenic Massive Sulphide) deposits can have resources totalling 40-50 million tonnes. In some cases, giant fields contain in excess of 100 million tonnes, such as the Kidd Creek deposit in Canada. Examples of this class of deposit occurring in Australia include Golden Grove, Jaguar / Bentley and Degrussa.

Kangaroo Caves Deposit

The deposit is located 7km south-east of the Sulphur Springs Deposit. Geologically the deposit sits at the same stratigraphic horizon as Sulphur Springs but has a shallower dip of approximately 300m to the northwest.

The deposit has been drilled along a strike length of 300m and has been traced by drilling to 1,000m down dip.

Panorama Trend

DEVELOP holds granted exploration and mining tenements covering approximately 27 kilometres of strike along the Panorama Trend which is a known VMS mineralised horizon.

The Panorama Trend hosts the Sulphur Springs and Kangaroo Caves copper-zinc deposits with a current metal endowment >230,000 Cu metal tonnes and >700,000 Zn metal tonnes.
The region is considered to have significant potential for the discovery of large VMS systems and for the expansion of known resources, particularly at depth below existing mineralisation and at further stratigraphic levels.

Further Work & Exploration Potential

Advanced prospects occur to the south of Kangaroo Caves and include Breakers, Man O’ War, Anomaly 45 and Jamesons which are all located on the same stratigraphic horizon. At each of these prospects drilling has returned ore grade copper and zinc intersections.

DEVELOP considers the potential to discover additional copper and zinc resources along the Panorama Trend to be excellent. Exploration work is aimed at identifying ancient volcanic centres that may have been the focus for sulphide fluid migration and subsequent deposition. The Company continues to refine this model to define targets for future exploration.
