Flinders receives assays from BID drilling

THE DRILL SERGEANT: Flinders Mines has received results from the first batch of assays for a follow-up drilling program targeted at defining additional Brockman Iron Deposit (BID) mineralisation at its Pilbara iron ore project in Western Australia.

Flinders said the latest results have given it a high degree of confidence that its geological model for additional high grade ore on the margins of its channel based deposits can be validated.

Additional testing of these target zones is being scheduled; however, the company said it is confident there is potential for an increased Direct Shipping Ore resource of shallow, easily mineable ore.

Following the completion of an initial Measured Resource status infill drilling program the company carried out in June, it embarked upon a reverse circulation (RC) drill campaign, which has been testing recently identified BID zones and completing required Indicated Resource status infill work.

“The results highlight good grades, thicknesses and close proximity to surface,” Flinders Mines said in its ASX announcement.

“Only three of the drill holes in this initial batch of assays failed to produce significant results, indicating the extent to which this mineralisation is extending – further, the majority of this mineralisation lies outside the scope of the current global resource estimations currently underway.

“The thickness of the intersections are excellent and they are all at or near surface and well above the water table, which has the potential to result in low strip ratios and mining costs.”

The current drill program being undertaken by Flinders Mines is almost complete, much earlier than what the company expected.

The faster than expected drill rates will result in the company’s 2011 drilling program finishing ahead of schedule and under budget.

“With a proven geological model, a mapping program in the hills has been implemented, not only in Delta but across the whole tenement, in the areas that may be prospective for high quality BID mineralisation,” Flinders said.

“This mapping has identified areas of BID mineralisation in the hills in addition to that already tested.

“Work is underway to prioritise these targets for drilling to test the extent and quality of this mineralisation as soon as necessary approvals and clearances can been obtained.

“The mineralisation identified on the flanks of the hills remains open and will be the focus of further investigation during the first half of 2012.”

Corazon continues Lynn Lake nickel intersections

THE DRILL SERGEANT: Corazon Mining has struck additional nickel/copper sulphide mineralisation during its ongoing drilling of geophysical (EM) conductors at its EL Deposit located within the Lynn Lake nickel sulphide project in Canada.

A recently-completed wedge hole intersected approximately 26 metres of strong matrix to semi-massive sulphide style mineralisation from approximately 715 metres down hole, before grading into disseminated sulphide mineralisation – lower grade material.

The company said it received good visual evidence of nickel and copper mineralisation, supported by the results of a hand-held XRF tool.

The latest wedge hole drilled by the company has paralleled the first wedge hole announced by Corazon in June, which returned 23.75 metres at 3.34 per cent nickel, 1.54 per cent copper and 0.079 per cent cobalt.

Corazon said the combined results from the two holes assist it in defining the northern extents of the conductor target.

Although the exact location of the second wedge hole has yet to be accurately defined by survey, Corazon anticipates it to lie within 25 metres of the first, providing support for the company to plan an additional wedge hole.

This follow-up hole will target deeper within the mineralised system that has been defined by the EM conductors.

To date Corazon has drilled five holes into an EM conductor situated below the EL Mine.

These holes have tested only a small portion of the target; however they have all intersected high-grade nickel-copper mineralisation.

Assay for holes completed last month have now been returned with results including:

–    2.23m at 3.84 per cent nickel, 0.41 per cent copper and 0.092 per cent cobalt from 715.25m; and

–    42m at 3.99 per cent nickel, 0.36 per cent copper and 0.027 per cent cobalt from 724m.
Corazon has interpreted the first of these holes to have intersected the fault bounded on the upper eastern edge of the EM conductor target.

The other hole targeted an area slightly away from the edge of the EM anomaly and intersected the upper bounding fault at 724 metres and semi-massive to disseminated nickel and copper sulphides for the next 32.72 metres.

Corazon said another hole completed in the recent campaign went off target due to driller error and malfunctioning survey equipment.

The company said that it decided to see what eventuated so let the drilling continue expecting it may intersect an area previously untested by drilling.

This strategy paid off with the hole intersecting some 80 metres of strong Type 1 disseminated mineralisation from 820 metres to 906 metres.

“It is significant that the results of Corazon’s drilling have returned some of the highest recorded nickel grades in the Lynn Lake mining camp,” the company said in itsASX announcement.

“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.

“Drilling of the conductor is continuing, with the commencement today of a hole that will test the conductor deeper and further to the south.”

Meteoric confirms gold at Tibooburra

THE DRILL SERGEANT: Meteoric Resources has completed follow-up sampling of an initial drilling program at the company’s New Bendigo prospect at Tibooburra, 300 kilometres north of Broken Hill in New South Wales.

The sampling has confirmed high-grade gold mineralisation from intersections including:

–    20 metres at 5.22 grams per tonne gold from 8 metres, including 3 metres at 22.62 grams per tonne gold from 13m; and

–    4m at 11.33g/t gold from 36m at end of hole.

Meteoric said the results highlight the potential of the New Bendigo prospect to host significant shallow gold mineralisation.

“The mineralisation intersected by the drilling represents the northern soil covered extension of a 1.2 kilometre-long zone of mapped sericite-altered phyllites and metasiltstones hosting old gold diggings,” the company said in its ASX announcement.

“Within this 100 metre to 300 metre-wide alteration zone a second line of old diggings is evident to the west of the trend drilled to date.

“The western trend is approximately one kilometre in length and remains to be drill tested.”

The latest results follow on from the company’s announcement from September of the completion of a first pass RAB/aircore drilling program at Tibooburra.

Meteoric has now completed follow up sampling of one metre intervals in mineralised zones of that drilling.

The company said the follow up sampling has confirmed a zone of mineralisation some 300m in strike length with best intercepts of:

–    20m at 5.22g/t gold from 8m, including 3m at 22.62g/t gold from 13m; and

–    4m at 11.33g/t gold at end of hole, including 2m at 21.87g/t gold from 36m.

“The mineralisation is interpreted to comprise multiple sub-vertical zones of quartz veining and stockworks within a broader zone ranging from 20 metres to 50 metres in width,” Meteoric said.

“The mineralisation appears to be strengthening to the south and is open in that direction.”

Six kilometres south of New Bendigo, further follow-up sampling was carried out on the Kink prospect, which the company said also confirmed anomalous gold grades in drill holes one kilometre apart.

Both the New Bendigo and Kink prospects occur close to a mapped regional fault structure, the New Bendigo Fault.

“Meteoric is most encouraged by the confirmatory assays from its first drilling program, which demonstrate the potential for New Bendigo to host shallow high grade gold mineralisation,” the company said.

“A program of mapping and sampling is to be carried out at New Bendigo in order to define further drilling targets along strike on the eastern zone and at the untested western zone.

“Further drilling is also planned at Kink to follow up the anomalous results from the wide-spaced drilling.”

Northern Star drills big numbers at Paulsens

THE DRILL SERGEANT: Northern Star Resources has achieved some impressive resource extension drilling results yet at the Voyager 1 lode at its Paulsens gold mine in Western Australia.

The company is confident the latest results could set up further increases in resources, production and mine life.

The intersections include:

–    18.8 metres at 62.7 grams per tonne gold, including 7.0 metres at 140.7 grams per tonne gold (with 0.85 metres at 773 grams per tonne gold);

–    13.3m at 12.2 g/t gold; and

–    6.4m at 120.2 g/t, including 2m at 345.4 g/t gold.

Northern Star said it will use the latest results to form part of its next resource upgrade, which in turn will underpin a revised mine plan for Paulsens, including increased mine life, production and cashflow.

The new mine plan will become an important aspect of Northern Star’s strategy to increase its total production to 200,000 ounces per annum from the current rate of 80,000 ounces per annum.

Northern Star said it considers these latest results from the Voyager 1 lode to be quite significant as they confirm the extension to the main ore zone, commonly referred to as the Upper Zone, it announced in September.

The company highlighted the first intersection, which returned multiple numbers of assays greater than 100 g/t gold, with a maximum intercept of 773 g/t gold.

It also pointed to the third intersection saying it adds further support for a substantial down plunge extension to the Voyager 1 lode due to it being the deepest mineralisation intersected in Voyager 1 to date.

Voyager 1 lode is the main ore source at Paulsens and has produced 100,000 ounces of gold over the past 15 months.

It continues to be open down plunge and dip and is emerging as the company’s major source of production for at least the next two years.

When combined with the potential of the Voyager 2 mineralisation, Northern Star is confident Paulsens stands to have a projected life of at least another five years.

“These significant high-grade results will make a substantial contribution to an upgraded mine plan for Paulsens, including increased resources, production and cashflow,” Northern Star Resources managing director Bill Beament said in the company’s announcement to the Australian Securities Exchange.

“Combine these extensions to Voyager 1 with the successful delineation of Voyager 2 and it is abundantly clear that the financial prospects for Northern Star are exceptionally bright.”

Results continue to encourage Laconia

THE DRILL SERGEANT: The good news keeps coming for Perth-based exploration company Laconia Resources.

The company has announced the intersection of further high-grade zinc and silver mineralisation from its maiden drilling program at the Lennons Find base metals project, near Marble Bar in the Pilbara region of Western Australia.

The latest results have been achieved from drilling at the Tiger prospect, with highlights including:

– 2 metres at 232 grams per tonne silver, 0.56 grams per tonne gold, 0.07 per cent zinc, 0.08 per cent copper from 15 metres; and

– 2 metres at 145 grams per tonne silver, 0.67 grams per tonne gold, 0.13 per cent zinc, 0.76 per cent copper from 6 metres.

Laconia said that it had confirmed the presence of ore grade mineralisation along strike in both directions.

Laconia recently released other results that it said had confirmed high-grade silver intersected near surface and along strike at the Bronze Whaler prospect.

The company has also intersected zinc-silver mineralisation outside the current Resource boundary at the Hammerhead prospect.

All of these high-grade results come from a recently completed a 42 hole, 1,939 metre reverse circulation (RC) drilling program conducted at the Lennons Find project.

The Lennons Find project currently has a JORC Inferred Resource of 853,000 tonnes at 115 grams per tonne silver, 7.7 per cent zinc, 0.7 per cent copper, 1.8 per cent lead at the Hammerhead prospect.

The company is set to commence resource modelling incorporating results from all three prospects immediately.

“We continue to be delighted with the results from our targeted drilling at the Lennons Find project,” Laconia Resources managing director Ian Stuart said in the company’s announcement to the Australian Securities Exchange.

“The additional high grade results from the Tiger prospect, combined with the previous results from Hammerhead and Bronze Whaler, paint a compelling picture of the project’s potential.

“Significant zinc and silver grades have now been intersected on strike, on either side of the existing Resource at Hammerhead, and we look forward to incorporating these new intersections in Resource modelling as soon as possible.”

Robust hits best copper intersection

THE DRILL SERGEANT: Gold and base metal exploration play Robust Resources has received some encouraging results from an ongoing drilling program being undertaken at the company’s Romang Island project in Indonesia.

A total of seven drill rigs a currently operating on the Romang Island project with focus corroborating earlier exploration drilling results.

Robust Resources is also hoping to expand the boundaries of the known mineralisation at the project.

The company said that the recently received assay results indicate that mineralisation continues well beyond the boundaries that have been defined by current drilling.

One hole, LWD120, was drilled on the south-eastern extremity of the Batu Mas prospect.

This hole and intersected high-grade massive to semi-massive sulphide mineralisation over a wide zone.

Results from LWD120 include:

–    22 metres at 7.74 per cent copper equivalent (1.36 per cent copper, 10.03 per cent lead, 10.24 per cent zinc, 0.14 grams per tonne gold, 57 grams per tonne silver) from 126 metres; and

–    10 metres at 10.25 per cent copper equivalent (2.36 per cent copper, 8.65 per cent lead, 16.76 per cent zinc, 0.16 grams per tonne gold, 61 grams per tonne gold) from 134 metres.

“This is a very encouraging result given that it is the strongest zone of mineralisation intersected so far,” the company said.

The zone of mineralisation is open at depth and to the east.

The company considers these initial results have indicated that the eastern part of Batu Mas is strongly mineralised in base metals.

The drilling has also intersected a number of copper-rich zones in the same area.

“LWD120 is one of our most exciting and significant intersections to date and demonstrates that Romang Island hosts significant copper-rich massive sulphide mineralisation,” Robust Resources managing director Gary Lewis said in the company’s announcement to the Australian Securities Exchange.

“It also confirms that these zones are still open for further discovery.

“These extensions, and other completely untested targets, such as the silver-rich Batu Perak prospect, will be the focus of future drilling campaigns.”

Robust Resources has now completed 22,000 metres of drilling at Romang Island.

The results from this drilling will be used to form the basis of a maiden mineral resource estimate, which the company said is due to be released by the end of the year.

“The final batch of core samples to calculate the resource estimate is now in transit to the laboratory in Jakarta,” Lewis said.

“Assay results from this batch of drill core samples, as well as others already at the laboratory will be released over coming weeks.”

Genesis encouraged by Chilean drilling

THE DRILL SERGEANT: Genesis Minerals has reported the receipt of encouraging results from the final three holes drilled at the company’s Dinamarquesa project located in northern Chile.

The company said it had intersected extensive zones of porphyry-hosted copper-gold and molybdenum during the drilling.

The results include:

–    17 metres at 0.53 per cent copper equivalent (0.29% copper, 0.15g/t gold);

–    80m at 0.48% copper equivalent (0.28 % copper, 0.16g/t gold, 117 parts per million molybdenum);

–    9m at0.55% copper equivalent (0.27 % copper, 0.25g/t gold, 130 ppm molybdenum);

–    17m at 0.77% copper equivalent (0.18% copper, 0.76g/t gold);

–    15m at 0.47% copper equivalent (0.30% copper, 0.21g/t gold); and

–    19m at 0.41% copper equivalent (0.25% copper, 0.11g/t gold, 101 ppm molybdenum).

In addition to the porphyry style mineralisation Genesis said it had also intersected high-grade gold mineralisation associated with quartz-sulphide veins, including:

–    0.2 metres at 49.2 grams per tonne gold;

–    0.3m at 21.1g/t gold;

–    0.64m at 8.2g/t gold; and

–    0.2m at 8.7g/t gold;

“The recent drilling has again returned very pleasing results with wide zones of porphyry hosted copper, gold and molybdenum mineralisation intersected,” Genesis Minerals managing director Michael Fowler said in the company’s announcement to the Australian Securities Exchange.

“The porphyry system remains completely open. It is untested to the north and at depth where further drilling is required to define the extent of the system and where we believe the greatest potential lies.”

Genesis’ interpretation of the latest drilling results is that they have confirmed that there is potential to define a large porphyry copper – gold – molybdenum system at the Dinamarquesa project.

The company said it also considers a recently-defined quartz-feldspar porphyry forms a major exploration target for future work at Dinamarquesa.

“The high-grade, vein hosted gold mineralisation returned from the final holes is also very encouraging with further detailed drilling required to define the continuity and extent of the vein mineralisation,” Fowler said.

Genesis Minerals entered into an agreement in August 2010 with a private Chilean company to acquire a 100% interest in the Dinamarquesa project.

Limited previous wide spaced drilling carried out on the project had delineated a number of high-grade gold structures.

The project is located within the Inca de Oro gold-copper belt, which forms part of the Palaeocene Porphyry belt of northern Chile.

Sherwin receives Roper River results

THE DRILL SERGEANT: Iron ore-focused exploration company Sherwin Iron has reported results from a drilling campaign the company has carried out at the Sherwin Creek prospect located within its Roper River iron ore project in the Northern Territory.

These recently-received results stem from a program of 91 RC drill holes totalling 4,506 metres, and 18 diamond drill holes totalling 607 metres.
The drilling was carried out so that Sherwin could test the continuity and boundaries of drill results it had previously reported to the market.

The best of the results received from the latest round of drilling include:

9 metres at 47.8 per cent iron from 11 metres;

8m at 49.7 per cent iron from 31m;

9m at 50.3per cent iron from 29m;

10m at 47.1per cent iron from 36m;

7m at 51.1per cent iron from 30m;

10m at 47.4per cent iron from 0m;

10m at 49.0per cent iron from 0m; and

10m at 50.1per cent iron from 22m.
 
Sherwin Iron conducted the infill drill program at Sherwin Creek over a nominal 400m by 200m drill hole spacing appropriate for the computation of a resource estimation.

SRK Consulting has commenced estimation of a maiden resource for Sherwin Creek, which is targeted for delivery by the end of October.

The company said it had confirmed that the middle and lower beds of shallow dipping iron oxide mineralisation that it announced to the market in June are continuous between sections.

Indicative beneficiation testing of the Sherwin Creek iron oxide mineralisation has commenced using samples the company obtained from a metallurgical diamond drilling program of 8 PQ diamond core holes for 229m to support the resource estimate.

“These are further excellent results from our 2011 drill program,” Sherwin Iron managing director Jerry Ren said in the company’s announcement to the Australian Securities Exchange.
 
“The additional drilling results should underpin a substantial maiden resource at Sherwin Creek and are consistent with our current Exploration Target of 400 million tonnes to 500 million tonnes at 40 per cent to 48 per cent iron for Hodgson Downs, Sherwin Creek and Mount Fisher.

“Our 2011 exploration season is still underway and the ongoing mapping and sampling of targets in the Mount Scott and Yumanji areas is on track to upgrade the company’s Exploration Target for the Roper River iron ore project before the end of the field season.”

Orrex hits Lakeside gold

THE DRILL SERGEANT: The results are back in from Orrex Resources’ first reverse circulation (RC) drilling program at the Lakeside prospect, on its Golden Mile South project in Western Australia.

The campaign consisted of eleven holes, four of which intersected gold mineralisation, for a total of 1,300m of reverse circulation drilling.

Orrex said the holes delineated a mineralised and altered shear zone consistent with those hosting major gold deposits in the Eastern Goldfields.

Prior to this program there had only ever been five RC holes testing bedrock drilled on the entire 100 square kilometre project area.

The company said it was excited about the results from this initial drilling and that it was also an encouraging outcome for both the Lakeside prospect and for the entire Golden Mile South project.

Orrex considers the results to have positive implications for its other targets at Golden Mile South targets.

It will now weigh up the benefits of infill drilling at the targets established at greater Lakeside prior to commencing any further RC testing at the Lakeside prospect.

The company’s thinking is that it may be more beneficial to work up the other targets at Lakeside with the intention to carry out a more comprehensive RC program on the greater Lakeside targets at one time.

Gold mineralisation was intersected in four drill holes along the central line of drilling within a 30 metre wide zone of alteration.

The best mineralisation was intersected in one hole where three, 6m to 14m wide, zones of gold mineralisation averaged between 0.7 grams per tonne and 1.59 grams per tonne gold, including 3m at 2.83 grams per tonne, from 30m, and 3m at 2.47grams per tonne gold from 54m.

Orrex said the RC program has given it a better understanding of the structural controls and style of mineralisation at Lakeside.

Because the campaign was focused to the north and south of the central line and was drilled down dip, Orrex said it is unable to determine the strike length of the structure at his time.

“We are pleased with the results of this inaugural RC program, Orrex Resources managing director Sonja Felderhof said in the company’s announcement to the Australian Securities Exchange.

“Hitting gold in bedrock on our first fresh rock program is exciting and highly encouraging not only for the Lakeside prospect but for the rest of the Golden Mile South project.

“The results validate our belief that the project is highly prospective for deposits similar to those in the region.

“The historic approach to exploration on the project area was focussed on discovering near surface alluvial deposits and consequently missed the opportunity to test the surface geochemical anomalies into bedrock.

“We will continue our evaluation on the Lakeside prospect and our other targets in the area to determine the best program going forward at Lakeside.

“We look forward to see what further work will realise at the Lakeside prospect, and other targets in the Golden Mile South project.”

Focus drills potential Perseverance expansion

THE DRILL SERGEANT: Recent drilling carried out by Australian gold producer Focus Minerals at its Tindals Mining Centre underground operation has resulted in a series of high-grade gold intercepts, which the company said highlights potential for further expansion around the Perseverance deposit.

Focus has also just poured its 200,000th ounce of gold since it started production from the Tindals underground operation in April 2008.

Approximately 125,000 ounces of that production has been mined from Perseverance.

“Perseverance has been an important ore body for Focus over the years and its production has been exceptional when you consider we only started there with a 76,000 ounces reserve,” Focus Minerals chief executive Campbell Baird said in the company’s announcement to the Australian Securities Exchange.

The recent campaign has targeted previously identified mineralisation to the north of the existing reserve, called the Perseverance North deposit, where Focus has outlined a 150 metre strike length of high-grade mineralisation, which remains open to the north and down dip.

Perseverance North was targeted to assess the southern strike potential as well as infill around previous high-grade results.

Focus said the drilling result appear to indicate Perseverance North has a moderate-steep southerly plunge, similar to the main quartz-sulphide ore body at Perseverance.

Recent drilling results at the main lode at Perseverance, including 4.5m at 21.6 grams per tonne gold, 2.3m at 12.3g/t gold, and 2m at 7.8g/t gold, have also confirmed a mineralised diorite lode west of, and running parallel to, the current Perseverance Ore Reserve.
 
High grade intercepts at the Perseverance North deposit include:

–    6 metres at 20.2 grams per tonne gold;
 
–    2.4m at 16.3g/t gold;

–    2.8m at 10.8g/t gold; and

–    2.7m at 10.0g/t gold.

High-grade intercepts in the diorites include:

–    16.9m at 16.0 g/t gold;

–    6.1m at 7.0g/t gold;
 
–    3m at 12.4g/t gold; and

–    9m at 3.5g/t gold.

“These results point to the potential for further expansion around the Perseverance ore body and, when you put them together with other work we’ve been doing across the wider underground operation, we are clearly in a very strong position to continue to deliver solid production from the Tindals underground month after month,” Baird said.
