Introduction

sed to Project ent for the Duketon Gold Project tection s the proval ted in verton, Regis Resources NL (ASX:RRL) is plea announce that it has submitted a Referral Docum to the West Australian Environmental Pro Agency (EPA). This document i commencement of the environmental ap process for the proposed gold project loca the Duketon region, 130km north of La Western Australia.

st of n Gold ranted pment facility truck gold ore from the other deposits to this regional mill. The Moolart Well gold deposit is the large eight deposits comprising the Duketo Project, all of which are located on g mining leases. The current develo concept is to construct a gold processing at the Moolart Well mine site and

The proposed initial development of the Project will be based on laterite and oxide ore from the Moolart Well deposit, supplemented by oxide and quartz ore feed from the Dogbolter and Erlistoun satellite deposits located 10 and 35km to the south of Moolart Well respectively.
