Outstanding drilling targets identified at Mt Venn copper-nickel-cobalt project in WA

Ground EM confirms numerous large bedrock conductors consistent with massive sulphide mineralisation at the project’s Eastern Mafic complex

Key Points

• Moving loop ground EM survey at the Eastern Mafic complex within the Mt Venn project is now 15% complete

• The survey has already identified numerous large bedrock conductors that show an EM response consistent with massive sulphide mineralisation

• These conductors are consistent with those previously identified by the recent airborne EM survey

• The Eastern Mafic complex sits immediately adjacent to the Mt Venn coppernickel-cobalt discovery, where mineralisation has been outlined over several kilometres and remains open in every direction

• The Mt Venn discovery is considered to be the tail-end of a mineralised system, with a major source nearby; Great Boulder believes the Eastern Mafic may host this source

• Drilling of these targets is anticipated to start in six weeks

• Latest drilling at Mt Venn discovery identifies new copper-nickel-cobalt lenses and extends existing mineralisation; Significant results include:

• 44m at 0.5% Cu, 0.2% Ni, 0.06% Co from 153m (downhole)

  • including 3m at 1.0% Cu and 2m at 1.2% Cu

• 27m at 0.6% Cu, 0.2% Ni, 0.05% Co from 43m (downhole)

  • including 5m at 0.9% Cu, 0.2% Ni, 0.07% Co

  • Including 5m at 0.9% Cu, 0.1% Ni, 0.02% Co

• 10.1m at 0.9% Cu from 229.3m (downhole)

  • including 5.9m at 1.1% Cu, 0.1% Ni, 0.02% Co

• Initial metallurgical testwork returns positive results

Great Boulder Resources (ASX: GBR) is pleased to report that it has taken another key step towards finding the source of its Mt Venn copper-nickel-cobalt discovery, with a ground EM survey identifying numerous large bedrock conductors.

The exceptional results from the moving loop electro-magnetic (MLEM) survey over the Eastern Mafic complex at Mt Venn confirms the presence of large bedrock conductors which have a conductive response consistent with massive sulphide mineralisation.

The conductors identified by the MLEM confirm those anomalies identified by the recent airborne EM survey. The MLEM is now progressing north to test strong airborne anomalies with coincident copper-nickel geochemistry.

Planning for a maiden RC and diamond drilling program is now underway, with results from the MLEM survey coming in on a rolling basis. On completion of the MLEM survey and geophysical modeling of the conductor plates, Great Boulder will mobilise a drill rig to site in order to start drill testing these anomalies in the Eastern Mafic complex in six weeks.

The Eastern Mafic complex sits immediately adjacent to the Mt Venn discovery, where drilling has outlined nickel-copper-cobalt mineralisation over several kilometres of strike.

Mineralisation at Mt Venn, which remains open in every direction, is copper-dominant and indicative of late-stage formation within the intrusion. The Eastern Mafic complex is being targeted because its geochemical signature suggests an earlier stage of formation, meaning it is potentially closer to the source or a feeder structure of the intrusion, as identified in the gravity survey, and therefore prospective for massive sulphide mineralisation.

The southern seven lines of the MLEM have now been completed and modelled, with three distinct conductors identified. The strongest response, located close to airborne EM conductor 22, has been modelled at approximately 100m below surface, extends over 500m along strike and is consistent with a massive sulphide source.

A second EM response is seen immediately above this conductor and appears to represent a fault offset (up-thrust) repeat of the same conductive source closer to surface. The combination of these two conductors is believed to be the source of the large airborne EM response associated with Anomaly 1 (Figure 2 and 3).

The survey is ongoing with only 15% completed to date (Figure 1). The survey is anticipated to take 2-3 weeks to complete.

Great Boulder Managing Director Stefan Murphy said each round of exploration provided more strong evidence of the outstanding potential at Mt Venn.

“These latest results continue to strengthen our belief that the Eastern Mafic complex is the feeder structure and may host the higher-grade source of mineralisation within the larger Mt Venn project,” Mr Murphy said.

“The airborne EM survey, MLEM survey and the geochemical results are all lining up perfectly.

“In addition to these exceptional results at the Eastern Mafic, we have outlined extensive mineralisation immediately next door at Mt Venn.

“This known mineralisation continues to grow with every drill program and remains open in every direction.

“But we also believe it is the tail-end of the mineralised system and that there is a substantial source nearby. The Eastern Mafic continues to demonstrate characteristics consistent with being that source.”

Drilling Results

Results from the first five RC holes (18MVRC001-005) and diamond tail 17MVRC030 have been received from the recently completed drilling program at Mt Venn. Drilling has identified new mineralised lenses which further extend the known mineralisation, which remains open in all directions.

Metallurgical testwork

Initial metallurgical trials have also been completed on a composite sample from Mt Venn (diamond hole 17MVDD002), testing metallurgical flowsheet options to produce separate copper, nickel and cobalt products. Positive preliminary results indicate:

• Moderate to low hardness and grindability (Bond Work index of 12.8 kWh/t)

• Copper can be selectively floated and cleaned to produce saleable copper concentrate

• Nickel and cobalt (+/- Cu) are recovered into a pyrrhotite concentrate which is sent to a hydrometallurgical circuit for leaching metals into solution

• Atmospheric (at 90 deg C) and pressure (at 105 and 150 deg C) oxidative leaching options have been tested

• Preliminary results indicate that high extractions of about 90% can be obtained for copper, nickel and cobalt under both test conditions

MOVING LOOP EM SURVEY

The survey is being carried out using a 100m x 100m loop on survey lines spaced 100m apart with readings taken at 50m intervals and infilled with 25m over the peak of the anomaly. A total of 102 stations have been surveyed and modelled over seven profile lines, representing approximately 15% of the planned survey over the Eastern Mafic.

The objective of the MLEM survey is to validate and better define the SkyTEM airborne anomalies, generating conductor plates for drill hole testing. Initial results have confirmed the presence of very large bedrock conductors, validating the airborne EM results.

The survey commenced at the southern end of the Eastern Mafic conductor trend, where strong, late time EM conductors were identified in the airborne EM. Initial modelling of the MLEM results has identified several conductors associated with the airborne response. The modelled conductor plates are highly conductive, ranging from 6,800 to 11,300 Siemens and located only 80-120m below surface and extend over 500m with a subtle northerly plunge.

The strongest response was observed at mid to late delay times centred at 557625E on Lines 6881900N and 6882000N and coincident with Anomaly 22 identified in the airborne EM survey.

Interpretation by Newexco, Great Boulder’s geophysical consultants, suggests this strong anomalous response is sourced by a bedrock conductor. The time constant is estimated to be around 115 ms, consistent with a massive sulphide source.

A secondary anomalous response was observed at early to mid-delay times centred at 557750E on Lines 6882000N and 6882100N. This anomalous response is superimposing with the main strong anomalous response observed at 557625E, giving the response seen in airborne Anomaly 1 (Figure 2).

The time constant is estimated to be around 24ms and interpretation by Newexco suggests this secondary anomalous response is likely caused by semi-massive sulphides

A third strong anomalous response was observed at mid to late times centred at 557200E on both Lines 6881900N and 6882000N, coincident with Anomaly 11 identified in the airborne EM. The time constant is estimated to be around 70ms, consistent with a bedrock massive sulphide source.

MT VENN RC AND DIAMOND DRILLING

Assay results have been received from the first five RC drill holes and diamond tail 17MVRCD030. The results continue to grow the mineralisation footprint at Mt Venn which remains open in all directions.

Significant wide zones of mineralisation have been intersected in 18MVRC001 at the northern extent of the Central zone and 18MVRC005 has confirmed the presence of a thick mineralised eastern lens. The diamond tail on hole 17MVRCD030 intersected the footwall shear zone and proved its depth extension with 5.9m at 1.1% Cu.

Diamond tail 17MVRCD030 was drilled to test the mineralised extension of the footwall shear zone. The hole intersected 10.1m @ 0.9% Cu approximately 100m down dip from drill hole 17MVDD03 that intersected 4.4m at 1.7% Cu and 10m at 0.7% Cu from within the footwall shear zone.

The diamond tail demonstrated the footwall shear zone is extensive and preferentially copper rich. RC hole 18MVRC008 has been drilled to test the up-dip extension of the footwall contact and 17MVRC010 has been drilled to test the down dip extension and upper mineralised lens (assays pending for both).

Figure 7. X-Section 6887460mN with DHEM conductor plates

Drill hole 18MVRC001 was drilled to test the northern strike extension of the central mineralised zone. This hole intersected shallow, wide mineralisation with 4m @ 0.7% Cu from 16m (downhole) and 27m @ 0.6% Cu, 0.2% Ni and 0.05% Co. The northern strike and down dip extensions remain open and will be further tested in the next drill program.

RC holes 18MVRC003 and 004 were drilled to confirm strike continuity. Both holes intersecting thick mineralisation consistent with the modelled down-hole EM plates, confirming continuity of the mineralised lens. Mineralisation remains open above and down dip, and importantly both holes were terminated above the footwall contact. Diamond tails will be planned off the end of these holes to test the depth extensions of the footwall mineralised shear zone.

RC hole 18MVRC005 was drilled to test if mineralisation continued further east behind previously drilled RC hole 17MVRC029 where only moderate mineralisation was intersected. A very wide zone of 44m @ 0.5% Cu, 0.2% Ni, 0.06% Co was returned, showing mineralisation extends further east than previously thought.

METALLURGICAL TESTWORK

Initial metallurgical trials have been completed on a composite sample representing a massive nickel-cobalt (pyrrhotite) zone within the central mineralised zone of Mt Venn. These initial trials aimed to investigate possible metallurgical flowsheet options and demonstrate the ability to produce separate value products from contained base metals – copper, nickel and cobalt. A summarised flowsheet is outlined in Figure 11.

==> picture [301 x 342] intentionally omitted <==

Figure 11. Simplified Flowsheet for Mt Venn Metallurgical Testwork (17MVDD002)

Preliminary results indicate that:

• Ore has moderate to low hardness and grindability (Bond Work index of 12.8 kWh/t)

• Copper is contained mainly in chalcopyrite (+/- covellite) while nickel and cobalt are included in the pyrrhotite matrix in solid solution (minor pentlandite).

• Chalcopyrite can be floated selectively from pyrrhotite to separate copper from other base metals into a bulk Cu concentrate that can be further cleaned to produce saleable copper concentrate. A copper concentrate assaying over 20% copper has been generated in preliminary flotation trials.

• Nickel and cobalt (and approximately 10% of the copper) are recovered into a pyrrhotite concentrate which is sent to a hydrometallurgical circuit for leaching metals into solution.

• Cleaner tail from copper cleaning stage is combined with the pyrrhotite concentrate to capture all base metals that were floated and then rejected in cleaner flotation.

• Two leaching options have been tested – atmospheric oxidative leaching (at 90 deg C) and pressure oxidation (at 105 and 150 deg C). Preliminary results indicate high extractions of about 90% can be obtained for copper, nickel and cobalt under both test conditions.

• Solution processing trials have not commenced as yet but it is envisaged separate copper, nickel and cobalt products will be generated. In that, copper will be recovered into a product that will be mixed with copper flotation concentrate to maximise the overall copper recovery. Nickel and cobalt will be separated by ion extraction (IX) or solvent extraction (SX) to generate individual chemical grade products for both metals (sulphate and/or sulphide products).

• All metallurgical leach tests have been carried out using site water collected from the Yamarna-Mt Venn project.

Once further copper cleaner tests and IX/SX products are produced, Great Boulder will be able to report estimated metal recoveries for Mt Venn from this testwork. Great Boulder will also commence metallurgical testwork on the copper dominant footwall contact once assay results are returned for all diamond drill holes.

		(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.	Geological logging was completed and mineralised intervals were determined by the geologists to be submitted as 1m samples for RC drilling. In RC intervals assessed as unmineralised, 4m composite (scoop) samples were collected for laboratory for analysis. If these 4m composite samples come back with anomalous grade the corresponding original 1m split samples are then routinely submitted to the laboratory for analysis. For the diamond drilling, samples were selected after geological logging and range in sample lengths from 0.3m
			to 1.5m.
			The samples were crushed and split at the laboratory,
			with up to 3kg pulverised, with a 50g samples analysed by

The sampling techniques used are deemed appropriate for the style of exploration.
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 used 140 to 130mm diameter drill bits. RC drilling employed face sampling hammers ensuring contamination during sample extraction is minimised. Diamond drilling was both NQ2 (50.5mm core diameter) or HQ (63.5mm core diameter). Core was oriented using the Reflex Act II RDIS core orientation tool.
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. Drilling techniques to ensure adequate RC sample recovery and quality included the use of “booster” air pressure. Air pressure used for RC drilling was 700- 800psi. Logging of all samples followed established company procedures which included recording of qualitative fields to allow discernment of sample reliability. This included (but was not limited to) recording: sample condition, sample recovery, sample method. Almost all of the RC drilling completed in the current programme had sample recovery logged as “good” and sample condition as “dry”. RC sample intervals recorded 54% 1m split samples, and 45% 4m composite samples (note: generally composite samples are in unmineralised zones). The remaining 1% were composites of a length other than 4m (typically at end of hole). The diamond hole drilling in the current programme had an average core recovery of 99%. While no issues relating to sample recovery have been note, final recovery assessment has not been completed. No quantitative analysis of samples weights, sample condition or recovery has been undertaken. No quantitative twinned drilling analysis has been undertaken at the project.
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. Geological logging of samples followed established company and industry common procedures. Qualitative logging of samples included (but was not limited to) lithology, mineralogy, alteration and weathering. Logging was supported by the use of a handheld XRF.
Sub-sampling techniques • If core, whether cut or sawn and whether quarter, half or all core taken. Splitting of RC samples occurred via cone splitter by the RC drill rig operators. Cone splitting of RC drill samples occurred regardless of the sample condition.
