ASX: MGV
Musgrave Commences Drilling Zinc- Silver and Copper-Gold Targets at Menninnie Dam
• Drilling program to test three new targets is underway
• A minimum of 1500m of RC and Diamond drilling is planned
• Assay results expected in late January 2015
Musgrave Minerals Ltd ("Musgrave Minerals" or "the Company") (ASX:MGV) is pleased to announce that it has commenced a drilling program to test three base metal targets at the Menninnie Dam Project in the southern Gawler Craton region of South Australia (Figure 1).
The drilling program will test both zinc-lead-silver and copper-gold targets at Erebus, Mallee and Taal in the highly prospective region. A minimum of 1500m of drilling is planned over at least three targets using a combination of reverse circulation (RC) and Diamond drilling.
Managing Director Rob Waugh said "The targets all look very prospective and each is of large enough extent to potentially host significant volumes of mineralisation. All the datasets align well to support the mineralisation model and the targets."
Musgrave Minerals entered a Joint Venture Agreement with Menninnie Metals Pty Ltd, a wholly-owned subsidiary of Terramin Australia Limited (ASX:TZN) to earn a 51% interest in the Menninnie Dam Project in the first stage, and up to 75% thereafter.
Musgrave recently completed detailed soil sampling and gravity surveys over a number of specific target areas at Menninnie Dam.

Soil geochemistry returned anomalous silver, gold and copper values at Erebus (Figure 2) co-incident with an induced polarization (IP) chargeability anomaly, versatile time domain electromagnetic (VTEM) response and gravity low. The geophysical characteristics of the target are similar to that at the Menninnie Central silver-lead-zinc deposit located only 4km to the north-east. A minimum of three drill holes are planned at Erebus to test individual targets within this large anomaly. Target depths vary between 60 and 150m.
The Mallee target is approximately 4km south of the Viper silver-lead-zinc deposit. Mallee (Figure 3) is a coincident gravity high, rimmed magnetic high and IP chargeability response with anomalous copper, lead, antimony, gold and zinc geochemistry at surface. The response is consistent with that commonly observed from copper-gold porphyry targets. A minimum of two drill holes are planned at Mallee with target depths of approximately 100 and
250m.
The Taal target is a coincident gravity high and VTEM anomaly located at the intersection of two significant regional structures (Figures 4a & 4b). A ground electromagnetic (EM) survey at Taal is scheduled to commence in the next two weeks. A single drill hole is planned to test this target.

Explanation
|
Commentary
|
Mineral tenement and land tenure status
|
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.
|
All drilling and soil sampling will be within joint
venture tenement EL5039 and EL4813 within the
Menninnie Dam Project area. MGV is earning an initial
51% interest in the project with TZN.
The current targets being drilled on EL5039 and EL4813 and soil samples are within the Nonning Pastoral Lease.
A Part B Agreement has been signed with the Gawler Ranges Native Title Group and current exploration areas cleared for exploration activities.
|
Mineral tenement and land tenure status
|
The security of the tenure held at the time of reporting along
with any known impediments to obtaining a licence to operate in the area.
|
The tenements are in good standing and no known
impediments exist.
|
Exploration done by other parties
|
Acknowledgment and appraisal of exploration by other parties.
|
Some historical drilling has been undertaken in
different areas on the tenements by MGV and third parties but none is directly relevant to the current targets.
Some previous broader based (400m x 400m) soil
sampling has been done by MGV at these targets.
|
Geology
|
Deposit type, geological setting and style of mineralisation.
|
Geology comprises Proterozoic metasediments that
have been intruded by Hiltaba-suite granitoids and overlain by lower sequences of the Gawler Range Volcanics.
Musgrave is exploring for multi commodity style
deposits consistent with an interpreted porphyry- epithermal type model.
|
Drill hole
Information
|
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:
• easting and northing of the drill hole collar
• elevation or RL (Reduced Level - elevation above sea level in metres) of the drill hole collar
• dip and azimuth of the hole
• down hole length and interception depth
• hole length.
|
Drill hole information will be reported when drilling is
completed and assays received.
|
Data aggregation methods
|
In reporting Exploration Results, weighting averaging
techniques, maximum and/or minimum grade truncations (eg
cutting of high grades) and cut-off grades are usually Material and should be stated.
|
Drilling has just commenced and results will be
reported once received.
|
Data aggregation methods
|
Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.
|
Drilling has just commenced and results will be
reported once received.
|
Data aggregation methods
|
The assumptions used for any reporting of metal equivalent values should be clearly stated.
|
No metal equivalent values are currently used for
reporting of exploration results.
|
Relationship between mineralisation widths and intercept lengths
|
These relationships are particularly important in the reporting of Exploration Results.
If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.
If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg 'down hole length, true width not known').
|
Drilling has just commenced and results will be
reported once received.
|
Diagrams
|
Appropriate maps and sections (with scales) and tabulations of
intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate

sectional views.
|
Balanced reporting
|
Where comprehensive reporting of all Exploration Results is
not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.
|
Drilling has just commenced and results will be
reported once received.
|
Other substantive exploration data
|
Other exploration data, if meaningful and material, should be
reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples - size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.
|
All material results from geochemical and geophysical
surveys and drilling related to these prospects has been reported or discussed.
Gravity data was collected using a CG5 gravity meter and differential GPS at a station spacing of 100x200-
400m.
|
Further work
|
The nature and scale of planned further work (eg tests for
lateral extensions or depth extensions or large-scale step-out
drilling).
|
A range of exploration techniques will be considered to
progress exploration on the completion of the current program.
|
Further work
|
Diagrams clearly highlighting the areas of possible extensions,
including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.
