ASSAYS RECEIVED FOR LADY MARY DRILLING PROGRAM
-
Assays have been received for the RC drilling program at the Lady Mary Prospect
-
Best intersection is 2m @ 3.20g/t Au and 1.90% Cu
Malachite Resources Limited (ASX Code: MAR) ("Malachite" or the "Company") is pleased to announce that assays have been received for drill samples from the recent program of reverse circulation drilling at the Lady Mary Prospect. The Lady Mary Prospect is located 6km west of Malachite's Lorena gold mine near Cloncurry in northwest Queensland (see Figure 1 - Location Plan).
Figure 1: Location plan of Lady Mary Prospect and Lorena Gold Mine
The drilling program consisted of eight holes (total 558m), testing the Lady Mary Prospect over a strike length of 400m. Hole lengths varied between 42m and 114m (refer Table 1 for drill hole details). The holes intersected metadolerite and quartz schist/quartzite units of the Toole Creek Volcanics, and mica schist units of the Mt Norna Quartzite. Zones of quartz-carbonate veining and alteration were also intersected.

Assays have now been received from the SGS laboratory in Townsville for a suite of 323 x 1m drill samples (including assay standards and duplicate samples), which were assayed for gold and a suite of accompanying elements. The only intersection of significance was in drill hole LERC04, which assayed 2m @ 3.20g/t Au and 1.90% Cu from 12m to 14m. All other drill holes returned low gold values (generally
The lack of mineralized intersections in the other six drill holes suggests that the mineralization previously sampled from the dumps surrounding the old pits is sourced from discontinuous pods of mineralization, none of which were intersected in the drill holes.
However, the intersection in drill hole LERC04 is to the east of the line of old pits and the gold-copper soil anomaly (see Figure 2), and this position was not tested by any of the other drill holes in this northern section of the prospect. Hence a program of follow-up drilling along strike and down-dip of this intersection is warranted.

COMPETENT PERSON STATEMENT:
The information in this report that relates to Exploration Results is based on information compiled by Mr Russell Meares, a Competent Person who is a Member of the Australian Institute of Geoscientists. Mr Meares is a part-time employee of Malachite Resources Limited. Mr Meares has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the activity being undertaken to qualify as a Competent Person as defined in the 2012 Edition of the 'Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves.' Mr Meares consents to the inclusion in this report of the matters based on his information in the form and context in which it appears. Exploration results are based on standard industry practices, including sampling, assay methods, and appropriate quality assurance/quality control (QA/QC) measures.

Commentary
|
Sampling techniques
|
-
Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.
-
Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.
-
Aspects of the determination of mineralisation that are Material to the Public Report.
-
In cases where 'industry standard' work has been done this would be relatively simple (eg 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.
|
Reverse circulation (RC) drilling was used to obtain samples for geological logging and assaying.
RC drill holes were sampled at 1m intervals and each 1m sample was split using a cone splitter attached to the cyclone to generate a split of 2-3kg to ensure sample representivity.
|
Drilling techniques
|
-
Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc).
|
Reverse circulation drilling utilised a 5 1/2 inch diameter hammer.
|
Drill sample recovery
|
-
Method of recording and assessing core and chip sample recoveries and results assessed.
-
Measures taken to maximise sample recovery and ensure representative nature of the samples.
-
Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.
|
All RC samples were weighed at the drill site, and all sample recoveries were deemed acceptable.
|
Logging
|
-
Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.
-
Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography.
-
The total length and percentage of the relevant intersections logged.
|
All RC drill chip samples are geologically logged in 1m intervals from surface to the bottom of each hole to a level that will support appropriate future Mineral Resource studies if required.
The logging of RC chip samples recorded the lithology, mineralogy, mineralisation, veining, weathering, colour and other features of the samples.
