Alloy commences Horse Well drilling

THE DRILL SERGEANT: Perth-based exploration play Alloy Resources has commenced a 3,500 metre air-core drilling program at its Horse Well project in Western Australia.

The purpose behind the drilling program is to enable the company to test the north of its recent Warmblood discovery on a 100 metre by 50 metre or 25 metre hole spacing.

The drilling is focused on an area where Alloy has interpreted the mineralisation to potentially join with mineralisation at the Filly South West prospect over a 500 metres strike length.

The Filly South West prospect is a high-grade Indicated Resource of 90,400 tonnes at 7.85 grams per tonne gold for 22,800 ounces of gold.

Alloy will also carry out drilling on its Mustang prospect in order to define the geometry and extent of mineralisation over a 400 metre long area.

The company said that it is very optimistic about the potential for further discoveries at both Warmblood and Mustang.

It also holds optimism for the under-explored nature of additional geological trends that lie adjacent to these and other prospects within the Horse Well project area.

The upcoming program of drilling is the first phase of a planned integrated exploration program the company has scheduled leading up to December.

The program includes:

–    A larger air-core drill program of approximately 6,000 metres in November 2011;

–    Initial soil geochemical sampling program covering 10 kilometres strike south of the Warmblood discovery;

–    Ongoing review of all historical exploration data and generation of new targets; and

–    Due diligence review of data from holders of prospective tenements in the region.

“This drilling program will focus on the northern extent of the Warmblood discovery zone and drill targets to the south of the discovery zone at Mustang,” Alloy Resources said in its announcement to the ASX.

“The company has also initiated heritage clearance programs for targeted areas adjacent to Warmblood, and these areas will be drill tested as soon as clearance has been obtained.”

Vector intercepts high-grade gold

THE DRILL SERGEANT: Vector Resources has received the first batch of assay results from a high priority drilling campaign being undertaken as part of the Phase 1 RC program at the company’s Mt Dimer project in Western Australia.

Priority holes of the Phase 1 drilling have targeted near mine locations of Lightning, Anomaly 2, Silver Wing and Golden Slipper South.

Mt Dimer tenements cover more than 2,029 hectares and the project currently hosts a JORC compliant measured, indicated and inferred resource of 377,200 tonnes at 5.8 grams per tonne gold for 70,230 ounces of contained gold.

The results of the drilling program received to date have identified substantial mineralisation at depth and along the strike of Lightning, while the drilling at Anomaly 2 has identified a significant intercept that will require further delineation for resource construction,” Vector Resources said in its announcement to the ASX.

“It is anticipated that these results will increase the current resource.”

Of the priority one targets already drilled, 16 holes totalling 1,418 metres of sample results are still pending for Silver Wing and Golden Slipper South.

Lightning was discovered during the sterilisation drilling for the Golden Slipper waste dump.

Vector said the drilling at Lightning has demonstrated mineralisation continues at depth and along strike.

Intercepts of note achieved during the drilling include:

–    6 metres at 24.81 grams per tonne gold inclusive of:-

–    1m at 136g/t gold, 4m at 20.98g/t gold, 7m at 13.07g/t gold, 10m at 14.39g/t gold, 9m at 10.18g/t gold, 7m at 5.28g/t gold, 18m at 2.86g/t gold, and 6m at 3.99g/t gold.

Anomaly 2 contains several zones of mineralisation and lies approximately one kilometre to the east of Lightning.

Vector said the current drilling had enhanced its understanding of the geology and mineralisation of the Anomaly 2 prospect;

Significant intercepts received from Anomaly 2 include:

–    4 metres at 21.71 grams per tonne gold from 50 metres inclusive of:-

–    1m at 11.85g/t from 50m, 1m at 28.90g/t from 51m, 1m at 19.40g/t from 52m, and 1m at 26.70g/t from 53m.

White Rock continues Mt Carrington drilling

THE DRILL SERGEANT: White Rock Minerals is currently undertaking a drilling program on its 100 per cent owned Mt Carrington project in northern New South Wales.

The program has been designed to expand the current shallow Inferred Resource base of the project of 190,000 ounces of gold and 10 million ounces of silver.

Drilling has been spread across a number of targets within the Mt Carrington project area.

Positive assays received from the first hole of a five-hole program at the White Rock silver deposit so far include results that the company has said confirms the continuity of strong silver mineralisation with widths and grade similar to what it has intersected in previous drilling.

Result from the White Rock deposit include:

–    22.5 metres at 70 grams per tonne silver from 9 metres and 28.6 metres at 69 grams per tonne silver from 28.6 metres;

–    37m at 79g/t silver from 21m and 15m at 65g/t silver from 138m;

–    81m at 82g/t silver from 82m;

–    21m at 61 g/t silver from 127m; and

–    51m at 60 g/t silver from 98m.

White Rock Minerals said the results enhance the prospect that drilling at White Rock North will lead to the definition of a new near‐surface silver Inferred Resource in addition to the existing eight million ounce silver Inferred Resource already defined at White Rock.

Assay results for the remaining 4 holes are expected in late September.

At the Lady Hampden silver‐gold deposit the company continued with the second phase of step‐out drilling with the first two holes of the nine‐hole program confirming further silver mineralisation based on field XRF and visible analysis.

“These two holes are located 300 metres to the east and down plunge of the Resource,” the company said in its announcement to the ASX.

“Assay results are expected in October and this program is anticipated to result in further extensions to the Inferred Resource.”

Earlier this month White Rock Minerals had reported it was undertaking further drilling at the Strauss‐Kylo gold deposits.

Drilling of potential extensions to the Strauss and Kylo gold Resources will be undertaken in October, as follow up to the positive results returned from holes drilled below the Strauss pit.

Mining study confirms Excelsior potential

THE DRILL SERGEANT: Excelsior Gold has completed a preliminary conceptual mining study on the Excelsior resource in the central portion of its 100 per cent owned Kalgoorlie North project.

The results of the study have supported the company’s belief the deposit has the potential for large open pit development.

Additional assay results received by the company from a recently completed reverse circulation drilling program at Excelsior also defined broad intervals of gold mineralisation and higher grade zones.

Excelsior Gold has interpreted this to demonstrate the deposit’s potential to extend the conceptual pit design deeper beyond its current 175 metre vertical depth.

The conceptual study was based on the current Excelsior resource model which contains Indicated and Inferred resources of 5.3 million tonnes at 1.47 grams per tonne gold for 250,900 ounces (at 0.6g/t lower cut).

Recently received assay results from a reverse circulation drilling program undertaken at the Excelsior deposit have demonstrated broad zones of gold mineralisation and higher grade intersections.

The company expects these results will enable it to extend the current resource model at depth to the north.

New intersections at Excelsior include:

–    32 metres at 1.10 grams per tonne gold from 120 metres, including 8 metres at 1.42 grams per tonne gold from 123 metres and 14 metres at 1.42 grams per tonne gold from 123 metres; and

– 12m at 7.09g/t gold from 59m, including 3m at 20.9g/t gold from 62m and 22m at 1.15g/t gold from 97m.

The drilling consisted of 15 reverse circulation holes totalling 2,711m over 750m of strike at Excelsior.

The company has received assays results for nine of the 15 holes to date, with further sample batches yet to be processed.
“These drill results are anticipated to significantly improve the resource grades estimated in these locations within the current resource model as well as improving the resource confidence and/or extending the current resource,” Excelsior Gold said in its announcement to the ASX.

“This extension of the model and increase in block grade will potentially drive the Whittle optimisation deeper, particularly in the north.

“The intercepts of 12 metres at 7.09 grams per tonne and 12 metres at 1.62 grams per tonnes are very significant as they intersect the current block model where block grades are less than 1.2 grams per tonne gold near the northern end of the current conceptual pit design.

“Pushing the optimisation deeper in the north may well have an impact on the overall depth of the conceptual pit extending it deeper than its current 175 metre vertical depth.”

Once it has received all assay results Excelsior Gold intends conducting new resource modelling to facilitate more detailed mine analysis.

The company said it believes the results of the conceptual mine design study at Excelsior are sufficiently encouraging to warrant an extensive infill and extensional drilling campaign.

This is expected to commence in late October subject to appropriate approvals.

Drilling will also be conducted at several of the satellite resources such as Jackorite, Castlereagh and Lochinvar in order to define possible reserves.

Further engineering and metallurgical testwork is planned in preparation for mine pre-feasibility studies on the Excelsior and surrounding satellite deposits.

Corazon continues nickel hits

THE DRILL SERGEANT: Canada-focused nickel play Corazon Mining has intersected further nickel / copper sulphide mineralisation.

The hits have come during an ongoing drilling program the company is conducting on geophysical (EM) conductors at its EL Deposit, located within the Lynn Lake nickel sulphide project in Canada.

The latest drilling supports Corazon’s interpretation that the EM conductors it has recently defined are likely to be substantial zones of high-grade nickel / copper sulphide.

The company has defined two strong EM conductors, which it considers may represent the same mineralised zone and extending it over 50 metres to 100 metres and at depth.

“These anomalies extend to the full effective range of the geophysical method, into areas not tested by drilling and may extend further,” Corazon said in its announcement to the ASX.

“The true dimensions of the mineralisation associated with the EM conductors have yet to be determined.

“Drilling has intersected a relatively flat upper bounding fault, in contact with high-grade mineralisation.

“This is a truncated profile for the mineralisation historically defined at the EL Deposit, which has a high-grade core of between 80 metres and 120 metres in diameter, central to disseminated mineralisation of up to 200 metres in diameter.”

So far Corazon has drilled three holes into an EM conductor located below the EL Mine.

Although these holes have tested only a small portion of the target, they have intersected high-grade nickel / copper mineralisation.

The discovery hole, which the company announced to the market in June, returned 23.75 metres at 3.34 per cent nickel, 1.54 per cent copper and 0.079 per cent cobalt and defined the northern extents of the conductor target.

Massive sulphide intercepted in the second hole that was announced in August intersected 2.4m of massive sulphide beneath the fault.

The hole Corazon is currently drilling currently has targeted an area away from the edge of the EM anomaly.

This hole intersected the upper bounding fault at 723.96m and immediately intersected semi-massive to disseminated nickel and copper sulphides for the next 32.72m.

Within this, two zones with strong sulphides exist, including 1.44m of semi-massive sulphide immediately below the bounding fault, and 6.97m of semi-massive and sulphide breccia from 739.26m.

Corazon said that it was significant that the latest drilling had returned some of the highest recorded nickel grades in the Lynn Lake mining camp.

“The predictability of the location of the mineralisation, coincident with the EM conductors, provides conclusive support that the EM anomalies recently defined represent semi-massive to massive sulphides, and hence high nickel and copper mineralisation,” the company said.

Corazon will continue to drill the conductor continue subsequent to the completion of the current hole, which has a target depth of around 900m.

Sheffield confirms scale of McCalls deposit

THE DRILL SERGEANT: Bulk minerals explorer Sheffield Resources has released the results from a 30 hole drilling program at its McCalls heavy mineral sand exploration project.

The project is located 110 kilometres north of Perth, near Gingin in Western Australia.

Of the 30 holes drilled, all returned mineralised intervals of greater than one per cent Heavy Mineral (HM), with all but two of the holes ending in mineralisation.

One drill hole was extended in order to test the depth potential of the deposit.

This 85.5 metres of mineralisation and was still in mineralisation at the end of the hole.

Drilling results that recorded significant intersections included:

–    85.5 metres at 1.52 per cent Heavy Mineral from 4.5 metres;

–    58.5m at 1.49% HM from 4.5m;

–    61.5m at 1.32% HM from 1.5m;

–    49.5m at 1.52% HM from 1.5m; and

–    45m at 1.60% HM from 6m.

“These drill results are excellent, and improve on both the average grade and the dimensions of the deposit as outlined by BHP’s prior drilling; confirming our belief that McCalls is potentially a very large scale, high titanium ilmenite project with significant zircon credits,” Sheffield Resources managing director Bruce McQuitty said in an announcement to the Australian Securities Exchange.

McQuitty also said the drill results exceeded the expectations set by historic work at McCalls.

The 30 hole drilling program was designed by Sheffield to infill earlier broadly spaced drilling carried out by BHP, which had explored the McCalls region during the early 1990s.

On one section Sheffield completed 25 drill holes to infill 8 holes drilled by BHP.

What the company found to be of significance is that the average width and grade of the latest drill intersections is higher and the average slimes component lower than those of the BHP drill intersections.

In a release to the ASX in January Sheffield declared an Exploration Target for McCalls of between 1.5 billion tonnes and 2.5 billion tonnes grading between 1.1 per cent HM and 1.3 per cent HM.

The average heavy mineral grade of 1.35% for all intersections achieved from the recent drilling program is above the higher target range.

Sheffield considers this suggests either the presence of a large zone of higher grade material within the overall deposit, or a conservative grade estimate for the Exploration Target.

Alligator continues Tin Camp drilling

THE DRILL SERGEANT: Brisbane-based uranium play Alligator Energy has released results from an ongoing drilling program being carried out at its Tin Camp Creek project in the Northern Territory.

Alligator has received results from two holes recently drilled at the Caramal prospect and six drill holes undertaken in the South Horn area.

Drilling at Caramal was limited in July due to a drill rig breakdown.

A second rig was sourced and used to drill the initial 6 drill holes in the South Horn area.

Drilling recommenced at Caramal in August designed to test for down dip extensions of mineralisation.

Uranium intersections at Caramal include:

–    20 metres at 2027 parts per million uranium from 24 metres and 13m at 3095ppm uranium from 2m; and

–    5m at 1184ppm uranium from 30m and 3m at 1194ppm uranium from 21m.

Mineralisation at Caramal is considered by Alligator to occur within structural breccia zones which are parallel to stratigraphy and is un-related to adjacent dolerite dykes.

“The results from recent drilling continue to confirm this model,” Alligator said in its announcement to the ASX.

“High grade mineralisation in CAD11-05 was associated with chert and chlorite breccias having strong visual similarities to the mineralised chert breccias from the Ranger No1. Orebody.”

Initial diamond drilling has been undertaken in the South Horn area with assay results received from the first six drill holes.

Four of the holes were drilled along strike from historic South Horn drill holes which intersected uranium mineralisation.

Drilling results from the South Horn Prospect include:

–    4 metres at 1061 parts per million uranium from 70 metres and 11m at 563 parts per million uranium from 41 metres;

–    2m at 1432ppm uranium from 76m and 2m at 1158 ppm uranium from  48m; and

–    5m at 978ppm uranium from 46m and 1m at 990ppm uranium from 34m.

Alligator considers a re-assessment of the area is warranted to determine the effectiveness of historic drilling orientations and the potential to intersect fracture and stockwork zones in the area.

The recent drilling has re-focused the company’s attention on the Caramal area and additional drill rigs have been engaged to accelerate drilling in September and October.

Drilling has commenced to the east of Caramal targeting potential distal strike extensions to mineralisation.

Drilling is also continuing to test down dip extensions to mineralisation to the north.

A further 2000 metres to 3000 metres of drilling is also planned in these areas in September and October.

Aphrodite confirms gold at North Menelaus

THE DRILL SERGEANT: Perth-based gold exploration play Aphrodite Gold has scored some encouraging results from a maiden reverse circulation drilling program recently completed over the company’s North Menelaus gold prospect.

North Menelaus is located four kilometres north of the company’s Aphrodite gold deposit near Kalgoorlie in Western Australia.

The company has recently concluded an initial five hole (874 metres) RC drill program to explore the North Menelaus zone over a strike length of 180 metres and to a maximum vertical depth of 180 metres.

Drilling was completed along three lines spaced 80m apart and in a zone where gold mineralisation had been reported in historic drill holes.

Historic gold intercepts achieved at North Menelaus include: 23m at 3.20 grams per tonne gold from 83m; 5m at 4.73g/t gold from 161m; and 2m at 5.48g/t gold from 122m.

All five holes drilled during the recently carried out program intersected significant gold mineralisation (greater than 0.5 g/t) with intercepts up to 15 metres in length (down hole).

Gold intercepts from the recently completed program include:

– 2 metres at 7.05 grams per tonne gold from 102 metres to 104 metres;

– 4m at 3.60g/t gold from 84m to 88m; and

– 15m at 1.33g/t gold from 122m to 137m.

“These results are very encouraging and confirm that our Aphrodite gold project has the potential to grow into a significant gold camp,” Aphrodite Gold exploration and development director Leon Reisgys said in the company’s announcement to the Australian Securities Exchange.”
Although North Menelaus is still in early stages of exploration activity Aphrodite said it could still be interpreted as possibly representing an offset of the same zone/structure which hosts the Chameleon gold prospect located 500m to the south south east.

Recent drilling carried out by Aphrodite Gold at Chameleon has already identified gold mineralisation over a strike length of 600m.
The North Menelaus prospect is one of a number of gold targets which the company has identified within the Aphrodite project.

Aphrodite said it plans to undertake further drill testing of North Menelaus before the end of 2011.

Bulletin Resources extends Nicolson’s

THE DRILL SERGEANT: Gold exploration play Bulletin Resources recently completed a program of RC drilling on its 100 per cent owned Nicolson’s gold project located near Halls Creek in northern Western Australia.
Two deep RC holes carried out by Bulletin have extended the high-grade Nicolson’s Footwall lode to a vertical depth approaching 300 metres.
Results from the final assays from the drilling at Nicolson Find have been received. Two of these holes, which targeted the down-plunge extensions of the recently discovered Footwall lode, intersected gold mineralisation including:

–    5 metres at 9.3 grams per tonne gold from 263 metres; and

–    5m at 7.4 g/t gold from 314m.

Bulleting considers these results have provided it with further confidence in the down-plunge continuity of the Nicolson’s deposit.

The company expects to complete further drilling on the Footwall lode as soon as it is able to have the RC rig returned to site.

This is currently anticipated to occur in early October.

Two additional lines of RC drilling were also completed north of the Rowdies deposit.

Rowdies is located approximately 800 metres south of the Nicolson’s pit and is one of several open pit resource targets along the main Nicolson’s host structure that have been subjected to limited testing so far.

Highlights from this drilling include:

–    4 metres at 27.5 grams per tonne gold from 57 metres; and
–    1m at 92.5 g/t gold from 57m;

“These highly promising down-plunge results provide us with even more confidence on the resource growth potential of Nicolson’s at depth,” Bulletin Resources managing director Marty Phillips said in the company’s announcement to the Australian Securities Exchange.
“The recent drill results from Rowdies and the adjoining Wagtail prospect continue to increase the likelihood for further high grade mineralisation at shallow depths. This will contribute valuable tonnages to our opening stockpiles at commissioning.”

Now that Bulletin has received all results outstanding from the recently completed drilling, the company has commenced work on updating its current resource model.

Bulletin said it expects the new resource estimate for the Nicolson’s project to be released in the first half of October.

Two drill rigs have been booked for the December quarter.

An air core rig will be used to continue the assessment of the open pit targets at Rowdies, Wagtail North and Wagtail deposits in addition to commencing the sterilisation drilling of the planned mine infrastructure and waste storage sites.

Aspire identifies Mongolian coal seam

THE DRILL SERGEANT: Northern Mongolia-focused coal play Aspire Mining has identified a new coal seam formation.

The seam is located around four kilometres from the resource area at the company’s Ovoot coking coal project in Northern Mongolia.

The company currently has four drilling rigs working to determine the resource potential of the area.

Aspire has completed 5,000 metres of exploration drilling as part of its 2011 program, in addition to infill, geotechnical and hydrological drilling.

A further 5,000 metres of exploration drilling is expected by the end of calendar year 2011.

“The exploration team has now intersected coal in three holes approximately four kilometres to the north east of the existing resource area,” Aspire Mining managing director David Paull said in the company’s announcement to the Australian Securities Exchange.

“The coal was logged as hard, bright or sugary coal and we now need to understand the extent of this coal seam.

“We have pre-collared a number of the holes to start core drilling to get coal quality data and determine the extent and orientation of the mineralisation.

“This will indicate whether the coal shallows and thickens as we head further south towards the resource area.”

Results from the three holes – which are 1.7 kilometres apart – included:

–    A total of 2.8 metres of coal from 261 metres;

–    A total of 3.1m of coal from 366m; and

–    A total of 3.1m of coal from 338m.

Aspire has a magnetics program planned in order to determine the structure and shape of the Ovoot Basin and to aid in the identification of possible shallower coal seams.

“With this view of the coal being closer to the base of the Jurassic sediments, it is now evident that potential coal is still open to the north east and east of the existing resource area,” Paull continued.

“We are currently exploring this area as part of the extensions to the Ovoot Resource area and to further determine the potential resource.

“Currently four drilling rigs from two drilling companies are on site at Ovoot with a fifth large-capacity rig expected later in October.

“It is expected that all rigs will be available to continue drilling through the winter.”

A larger Coretech 1800 rig has recently arrived on site, which means the company is now able to drill the holes that are required to be deepend.

This will enable it to test for the potential coal seam extensions.

Aspire is also set to commence a close spaced magnetics program as a supplement to existing seismic data and to help guide interpretations.

The company is now considering ground versus airborne options to address the whole Ovoot Basin, which Aspire considers will provide it with an effective exploration targeting tool going forward.
