WIDESPREAD GOLD MINERALISATION AT TOPPIN HILL AND YAFFLER PROSPECTS
(SOUTH YAMARNA JV WITH
SUMITOMO METAL MINING OCEANIA - 50% INTEREST)
Highlights
-
Bedrock gold mineralisation intersected at Toppin Hill from 400 to 1,800 metres north of existing high‐grade drilling
-
Strike of Toppin Hill mineralisation including grades greater than 1.0 g/t Au extended to over three kilometres
-
Bedrock drilling at Yaffler confirms gold mineralisation in prospective quartz dolerites
-
One‐metre re‐sampling at Smokebush returns 2 metres at 2.15 g/t Au from 94 metres, including 1 metre at 4.01 g/t Au in hole 16SYRC0044
Gold Road Resources Limited (Gold Road or the Company) is pleased to announce that reverse circulation (RC) drilling at two prospects, Toppin Hill and Yaffler, both within its South Yamarna Joint Venture (SYJV) tenements in Western Australia has intersected anomalous bedrock gold mineralisation over widespread areas. The SYJV is owned 50:50 by Gold Road and Sumitomo Metal Mining Oceania Pty Limited (Sumitomo)

The Toppin Hill Prospect is located in the Breelya‐Toppin Hill Camp, while the Yaffler Prospect forms part of the Riviera‐Smokebush Camp, 15 kilometres to the north of Breelya‐Toppin Hill Camp (Figure 6).
Executive Director Justin Osborne said: "We are pleased with results from both the Toppin Hill and Yaffler programmes. In extending the mineralisation at Toppin Hill to over three kilometres we now have a significant gold system with multiple mineralisation styles to follow‐up with new drilling. At Yaffler we were able to identify anomalous gold mineralisation within the important dolerite rocks that have proven to be a good host to high‐ grade gold at the nearby Smokebush Dolerite prospect. We are now working on more detailed targeting at both prospects, as well as the Smokebush Dolerite with its new detailed magnetics, and hope to be drilling for higher‐ grade zones in all three prospects in the second half of 2016."
Toppin Hill Prospect
Twelve RC holes were drilled at Toppin Hill (Figures 1 and 2), from 400 to 1,800 metres north of previous RC drilling, testing the northern extensions of mineralisation identified in 2014‐2015. The programme confirmed the continuation of the mineralised system with five holes returning intersections greater than 1.0 g/t Au, and two styles of gold mineralisation identified. Mafic hosted gold mineralisation consists of narrow, discrete shear zones within basalt, with a best result of 4 metres at 1.24 g/t Au from 149 metres in hole 16SYRC0084. Wider zones of lower grade gold mineralisation were intersected in shear zones hosted within the dacite country rock with trace amounts of disseminated pyrite, with a best result of 36 metres at 0.52 g/t Au from 56 metres in hole 16SYRC0081. The new results increase the strike length of bedrock gold mineralisation at greater than 1.0 g/t Au at Toppin Hill to over three kilometres.

Yaffler Prospect
A total of 19 RC holes drilled at Yaffler (Figures 3 and 4) tested below an extensive aircore saprolite gold anomaly for evidence of primary bedrock mineralisation. Twelve holes successfully intersected gold mineralisation in excess of 0.1 g/t Au, with a best result of 4 metres at 0.61 g/t Au from 134 metres in 16SYRC0070. Drilling identified a sequence of interlayered mafic sediments and mafic intrusions, including units of prospective quartz dolerite similar to the Smokebush Dolerite (ASX announcement dated 20 April 2016) which is two kilometres to the east. Anomalous gold is generally hosted within the dolerites and associated with shearing, quartz veining and pyrite‐dominant sulphide alteration. The presence of a large gold anomaly overlying the targeted prospective host rocks is a promising result, with all the indicators of a mineralised gold system being identified in this first programme of wide‐spaced bedrock drilling.
Detailed interpretation of the results, and collection of one‐metre re‐samples from the anomalous four‐metre composite samples is currently underway at both prospects with a view to identifying specific targets for follow‐ up drilling.
