ASX / Media Release 1 June 2012

Drilling Commences at Boomey Copper-Gold Project, NSW

Drilling has commenced on the first of four planned 200 m holes

Target is an IP anomaly with visible copper mineralisation in surface outcrop

IP anomaly is coincident with a prominent magnetic low that may be caused by alteration

due to hydrothermal fluids

Associated circular pattern of resistivity highs resembles those formed by alteration

around intrusive porphyry stocks

Target zone is located 9 km north of Copper Hill porphyry copper-gold deposit

Goodrich Resources (ASX:GRX) (“Goodrich”) is pleased to announce that drilling has commenced at its

100%-owned Boomey Project, 12 km north of Molong, near Orange in NSW (Figure 1).

The target of the drilling is an Induced Polarisation (IP) chargeability anomaly (Figure 2). The 3D

model of the chargeability anomaly is 500m by 400m in horizontal extent and at least 300 m in vertical

extent.

The IP anomaly is accompanied by a distinct resistivity high (Figure 3) and a prominent magnetic

low (Figure 4). The coincident resistivity high forms part of a larger circular pattern of resistivity highs.

This circular pattern resembles those formed by alteration around intrusive porphyry stocks.

In addition, recent mapping of the anomaly position has discovered surface outcrops of altered andesitic

volcanic rock containing visible copper mineralisation (Figure 5). The copper mineralisation consists of

malachite and azurite coating fracture surfaces and native copper disseminated through the rock. These

outcrops have been missed by previous explorers.

volcanic rock contains malachite (green), azurite (blue) and disseminated native copper.

The Boomey Project

The Boomey Project lies within the Ordovician-aged Molong Volcanic Belt, the eastern structural

subdivision of the Macquarie Arc, a world-class porphyry copper-gold province within the Lachlan

Orogen of eastern Australia. The Macquarie Arc hosts the giant Cadia-Ridgeway (Newcrest) and

Northparkes (Rio Tinto) copper-gold mines, the Cowal (Barrack) and Peak Hill (Alkane) gold mines, and

several other significant deposits including Copper Hill, Marsden, and Wyoming.

IP Survey details

The seven line dipole-dipole IP survey was conducted by a previous explorer but prominent responses in

the data had not been investigated. The IP survey utilised a dipole spacing of 100m along each line,

giving the survey a penetration depth of at least 200 m. Consultant geophysicist Steve Collins of Arctan

Services Pty Ltd modelled the raw data using 3D inversion software and examined the resulting

chargeability and resistivity models as plans and sectional views.

Goodrich Managing Director Rod Sainty commented: “The combination of geophysical signatures at

Boomey is very encouraging because it matches those associated with known porphyry copper-gold

deposits. Our discovery of visible copper mineralisation at surface is a bonus. The project demonstrates

the exciting potential of the Goodrich portfolio.”
