Spargoville Drilling Delivers High Grade Gold Results
HIGHLIGHTS
-
Significant gold intersections reported in several holes including high grade intercepts
-
24m at 3.05 g/t including 8 metres at 4.0g/t in hole MXENRC04

Drilling, sampling and assay protocols to JORC 2012 standard
Maximus Resources Limited (ASX: MXR) is pleased to update shareholders following completion of the Company’s maiden drilling program on the Eagles Nest project in December 2015 and the receipt of assay results from the Project, located 70 kilometres south of Kalgoorlie, WA.
A total of 8 holes were completed for a total of 809 metres testing for strike and depth extensions to known mineralisation in the Eagles Nest goldfield. Visual logging of the drill chips by the geologist confirmed alteration and sulphides at the interpreted mineralised horizon in 7 holes.
A further important component of this drilling program is that it was designed to check the validity of historical mineralised intercepts, by drilling adjacent to or twinning previous drillhole locations, and assaying all samples using the fire assay method. Technical reports indicate that utilising the partial leach or aqua regia assaying method on high grade oxide samples (particularly samples with a high coarse gold component) does not provide a representative assay result.
Significant mineralised intersections recorded in the recent Eagles Nest drill program include 24m @ 3.05g/t , from 19m, including 8m @ 4.0 g/t from 35m, in hole MXENRC004, 7m @ 4.0 g/t from 33m, including 1m @ 14.7g /t from 34m in hole MXENRC005, 6m @ 1.98g/t from 81m, including 1m @ 5.3g/t from 81m in hole MXENRC07. Alteration assemblages included biotite, pyrrhotite, pyrite, arsenopyrite and chalcopyrite and are typical in areas of stronger gold mineralisation.
The Eagles Nest project is located on the Spargoville shear approximately 8km south of the previously mined high grade Wattle Dam gold mine. The drill results at the Eagles Nest Project demonstrate the potential for similar high grade gold mines, along strike from Wattle Dam, within the prospective Spargoville Shear Zone.
Results to date indicate a mineralized body dipping steeply to the east, and plunging to the north is present at Eagles Nest.
The company is currently planning the next drilling program on the Spargoville tenements, with approval received for the subsequent Eagles Nest drilling program.

Figure 2: Cross section showing recent RC drill results from holes MXENRC04 and RC07 with historical results shown in half tone
MXR is now sufficiently encouraged that the correlation between recent drilling and historical results will allow the company to include past drill assay results in planned preliminary resource calculations for internal use only. The historic data cannot be considered JORC compliant, however the correlation (see figure 2) between recent RC holes drilled perpendicular to historic drillholes is sufficiently robust to warrant inclusion in internal calculations. Future drilling will however include further infill and twin drilling to increase the confidence and accuracy of the existing mineralised outline.
One drill hole was cancelled due to difficulties accessing the location with the large drill rig available to complete the drill program. This hole may be completed in a subsequent drill program when a smaller unit is available.
