These assays follow from recent Reverse Circulation (RC) results at the Dexy prospect (see ASX announcement dated 26 May 2016) and confirm the prospectivity of the Round Dam trend including the Waihi Lode Complex.
Eastern Goldfields Limited (ASX:EGS) ( Eastern Goldfields or the Company ) is pleased to announce that Reverse Circulation drilling on the Walhalla North Prospect ( WNP ) at Davyhurst in Western Australia has returned encouraging results.
The WNP is approximately 14 kilometres south of the Company’s 1.2Mtpa processing plant. A project review of the Round Dam mineralised trend identified the potential source for shallow oxide resources at this location, in the area between the Walhalla and Federal Flag pits. Of particular interest was historical drilling results including 8m @ 17.14g/t, 8m @ 14.64g/t and 4m @ 20.53g/t within the WNP.
The WNP is situated midway between the Federal Flag and Walhalla open pits which are 1.1 kilometres apart. Walhalla and Federal Flag deposits were both mined in 2007 and 2008 as part of the greater Davyhurst Project.
The current drill program was designed to:
-
assist in the development of structural and geological models for the WNP, primarily aided by diamond drilling;
-
confirm the location and tenor of the existing drilling via a twin hole; and
-
provide additional data required to validate a Mineral Resource estimate.
Executive Chairman Michael Fotios said:
“This area is considered highly prospective and is one of a number of similarly advanced high priority prospects that are identifiable within the existing and extensive drilling database. We will now aim to extract additional value from this prospect by drilling step-out holes along strike and down dip. These results will bring us back to this prospect in the near future.”
1
The WNP mineralisation has been defined over a strike length of greater than 200 metres, while the structure itself remains open to the north, south and down dip. Further infill and extensional drilling is planned, which will be used to determine a maiden Mineral Resource estimation. Assay results from sampling of diamond drill holes at WNP are awaited.
Within the Round Dam trend the dominant rock types are fine grained basalt, high magnesium basalt, dolerite, ultramafics, sediments and volcaniclastics. Mineralisation at WNP is hosted by talc-chlorite mafic schist. The schist unit is surrounded by moderately massive tholeiitic basalt intercalated with thin dolerite and high magnesium basalt units. The schist is typically between 10 to 20 metres thick and has a strongly developed shear fabric. The schist lies between basaltic units to the west and sedimentary and volcanoclastic units to the east. Mineralisation favours the mafic units.

JORC CODE, 2012 EDITION – TABLE 1 REPORT TEMPLATE
Section 1 Sampling Techniques and Data
Information for historical (Pre Eastern Goldfields Limited from 1996 and 2001) drilling and sampling has been extensively viewed and validated where possible. Information pertaining to historical QAQC procedures and data is incomplete but of a sufficient quality and detail to allow drilling and assay data to be used for resource estimations. Further, Eastern Goldfields Limited has undertaken extensive infill and confirmation drilling which confirm historical drill results. Sections 1 and 2 describe the work undertaken by Eastern Goldfields Limited and only refer to historical information where appropriate and/or available.
