ASX Announcement

MUSGRAVE PROVINCE RC DRILLING OF EM TARGETS COMMENCES

Woomera Mining Limited (ASX: WML, Company) is pleased to announce that RC drilling of 5 EM conductors identified in the recent Moving Loop Electromagnetic Survey (MLEM) has commenced on the Company’s Musgrave Block tenements. The 4,000 metre drilling program will test five significant conductors identified during the MLEM survey. The conductors are coincident with the magnetic features previously identified by WML and may represent copper-nickel-cobalt mineralisation in Giles Complex ultramafic intrusive rocks that underlie the tenements.

Woomera’s Musgrave Alcurra-Tieyon Project

The Musgrave Alcurra-Tieyon project is the subject of a JV with OZ Minerals Ltd (ASX: OZL) that enables OZ to earn up to 75% of the project for an expenditure of $7.5m.

The project area lies immediately east of the Anangu Pitjantjatjara Yankunytjatjara ( APY ) lands. The Stuart Highway and the Adelaide-Darwin railway pass through the project area. The exploration focus in the area is on Ni-Cu-Co.

RC Drilling Program

The immediate exploration program has been designed to test conductors at Healy, Gallagher, O’Mahony, Walsh and Cavanagh (Figure 2).

Figure 2 – RC drill targets at Healy, Gallagher, O’Mahony, Walsh and Cavanagh

Healy

The Healy area was first identified by RTZ in 1996 after flying four experimental EM lines. Further work to drill test the conductor was never carried out.

The recent MLEM survey highlighted a significant conductor at Healy which was interpreted as having potential for Ni, Cu and PGEs within layered ultramafic rocks.

Woomera’s magnetic 3D inversion modelling which allows for remanence predicts a susceptible body at ~100m and several hundred metres in length.

Gallagher represents a significant conductor highlighted initially from Woomera’s Vector Residual Magnetic Intensity modelling and corroborated by the recent MLEM survey.

Cavanagh

Cavanagh was first identified by CRA as a reversely polarised magnetic feature. CRA followed up experimental airborne EM which identified an early time conductor at Cavanagh. CRA drilled one RC drill hole to 28m that intersected ultramafic rocks with anomalous Ni, Cr, Co and Cu.

VRMI modelling by Woomera identified a significant drill target (Figure 7).
