Gold Road continues to deliver results

THE DRILL SERGEANT: Gold Road Resources has received further high-grade gold intercepts, which it claims has identified at least three new gold targets in the Central Bore Area across its wholly-owned Yamarna Belt, located in Western Australia.

The latest results from Central Bore were achieved on Central Bore North and the Attila Trend.

“Our continued exploration success and continuing resource delineation in the Central Bore area is providing Gold Road with a solid foundation for us to move the Company into a development phase and future gold production in the region,” Gold Road Resources chairman Ian Murray said in the company’s announcement to the Australian Securities Exchange.

Gold Road said around two thirds, (~100,000 metres) of the company’s 2012 drilling program will focus on finding and proving-up new gold discoveries across the tenements.

This drilling will be carried out on the Tatar, VTEM, Dorothy Hills, Tobin Hill targets.

The remaining third of the drilling campaign (~50,000m) will focus on Gold Road’s advanced projects at Central Bore and Attila Trend.

Gold Road’s current extensional and infill drilling program along the Attila Trend aims to identify additional higher-grade resources to supplement production from the high-grade Central Bore Project in order to justify the development of our own moderate-tonnage processing plant.

It is also aiming to increase the overall resource with the aim of growing towards a bulk-tonnage operation.

The company expects this drilling to improve its confidence in the projects and expand the existing resources.

Exploration highlights from activities located on or around Gold Road’s advanced projects include:

Khan North

–    1 metre at 17.35 grams per tonne gold from 112 metres.


–    1m at 30.28g/t gold and 1m at 4.62 g/t gold from 77m; and

–    1m at 12.03g/t gold from 126m.

Attila North

–    1m at 23.40g/t gold from 74m within 34m zone at 0.98g/t gold from 51m; and

–    1m at 11.88g/t gold from 69m within 4m zone at 3.47g/t gold from 67m.

Attila South

–    6m at 3.17g/t gold from 94m within 20m zone.

Elvis – Hann South area

–    Drilling has identified mineralised zones associated with five trends: Elvis; Contact; Attila; Tamerlane; and Hann.

Central Bore North

–    4m at 6.11g/t gold from 119m, including 1m at 18.4g/t gold;

–    3m at 3.64g/t gold from 146m and 3m at 5.37g/t gold; and

–    5m at 3.84g/t gold from 41m, including 1m at 13.4g/t gold.

Gold Road also conducted a Sub-Audio Magnetics (SAM) geophysical survey across the Central Bore Area, which confirmed the existing mineralised structures and identified at least three new targets.

The company is of the opinion SAM could be a quick and cost effective tool in gold exploration in other parts of the Yamarna Belt by assisting it to generate and narrow-down new drill targets.

West African hits 6m at 5.78g/t gold at Moktedu

THE DRILL SERGEANT: West African Resources has received high-grade results from a recently-completed first-pass diamond drilling at the Moktedu prospect situated on the company’s 100 per cent-owned Boulsa gold project in Burkina Faso.

West African completed six core holes in December 2011 and January 2012 for a total of 720 metres (including pre-collars) over a strike length of approximately 500 metres in the central portion of the Moktedu prospect.

The company said two of the latest holes had confirmed high-grade mineralisation dips to the northwest, in contrast to its previous interpretation based on earlier shallow drilling.

The diamond drilling program has returned two significant results:

–    21 metres at 1.13 grams per tonne gold from 121 metres, including 1 metre at 10.96 grams per tonne gold; and

–    6m at 5.78g/t gold from 74m, including 1m at 28.40g/t gold.

The company said some shallow drilling has been carried out between these two results that it has not optimised to properly intersect the moderate northwest dip of mineralisation.

The area is to be tested with diamond drilling oriented towards the southeast once the company has completed a diamond drilling program it currently has underway at the Meguet prospect.

West Africa has also received further near surface high-grade results from reverse circulation (RC) drilling including:

–    4m at 2.67g/t gold from 4m;

–    8m at 1.71g/t gold from surface;

–    4m at 8.39g/t gold from 4m; and

–    20m at 0.64g/t gold from surface, including 8m at 1.24g/t gold.

The company highlighted the point that the 6m at 5.78 g/t gold intercept occurs 50m down dip of the RC drilling intercept of 20m at 0.64g/t gold and another of 5m at 0.92g/t gold.

It said these intercepts combine to indicate potential to intercept further mineralisation in deeper drilling beneath numerous near surface broad plus-0.5g/t gold intercepts from aircore and RAB drilling along strike to the northeast and southwest.

“A result like six metres at 5.78 grams per tonne gold, 50 metres down dip of a modest result of five metres at 0.92 grams per tonne opens up the potential right along the eight kilometre Moktedu strike length,” West African Resources managing director Richard Hyde said in the company’s announcement to the Australian Securities Exchange.

“We are continuing to map the Moktedu structure with shallow aircore and RAB drilling.

“Numerous anomalous results have been returned, which will be followed-up by deeper diamond core and RC drilling during the field season.”

IMX eyes Tomahawk Target

THE DRILL SERGEANT: IMX Resources identified an Exploration Target tonnage of 150 million tonnes to 230 million tonnes at 25 per cent to 35 per cent iron for the Tomahawk iron prospect, located 25 kilometres southeast of the Cairn Hill magnetite-copper mine in South Australia.

The new Tomahawk Exploration Target estimate brings the current global iron Exploration Target tonnage for the company’s 100 per cent-owned Mt Woods iron project to between 200Mt to 380Mt.

This figure includes the Exploration Target for the Bumblebee and Fitzgerald Dam iron prospects the company previously reported in November 2009.

“IMX is now approaching a potential one billion tonnes combined iron resources and targets for the Mt Woods iron project based on exploration target tonnages and the recently announced iron resource of over half a billion tonnes at Snaefell,” IMX Resources managing director Neil Meadows said in the company’s announcement to the Australian Securities Exchange.

“Our South Australian magnetite strategy is on track with the Mt Woods iron project continuing to develop into a major iron ore asset with enormous upside growth potential.”

The target tonnage was estimated along a 3km strike length of the main Tomahawk magnetite prospect.

IMX said it still has a number of other magnetic targets nearby, which it has yet to drill-test that missed out on being included.

The company is now planning a number of drill campaigns over the next nine months to test these and other targets with a view to adding them to the Mt Woods iron project global exploration target resource base.

Intermin hits deeper gold at Teal prospect

THE DRILL SERGEANT: Intermin Resources has received assays for two deep cored holes recently drilled at the Teal prospect situated on the company’s Binduli north project, located 12 kilometres northwest of Kalgoorlie.

According to Intermin the drilling resulted in multiple intercepts of gold mineralisation at depths up to 300 metres from surface.

This is much deeper than the mineralisation the company had previously identified at the Teal prospect.

Highlights from the drilling include:

–    5 metres at 17.8 grams per tonne gold from 269 metres;

–    2m at 8.62g/t gold from 305m;

–    3m at 2.15g/t gold from 221m; and

–    4m at 2.66g/t gold from 230m.

The recent drilling was undertaken by Interim to test for extension of gold mineralisation at depth, to obtain information on the Teal ore body structure and to provide samples of Teal primary mineralisation for metallurgical testwork.

The company said observation of stronger grade mineralisation is consistent with a near vertical shoot of mineralisation with a southerly plunge.

Intermin has paid a lot of attention to the Teal prospect in regard to exploration activity over the past three years.

Drilling has resulted in the definition of gold resources of approximately 100,000 ounces at Teal in the form of a supergene resource overlying primary mineralisation.

“Recent pit optimisation of the Teal resource suggests that a relatively low risk starter pit accessing principally soft oxide supergene mineralisation could be established and a pit design has been developed based on this scenario,” Intermin Resources said in its ASX announcement.

“Total mineralisation within the Stage 1 starter pit was estimated at 271,000 tonnes at 2.63 grams per tonne gold for a total of 22,888 ounces.”

Intermin said it was anticipating receiving approvals for the mining of the Teal supergene soon.

The company will make a final decision to mine upon receipt of these approvals and the conclusion of toll treatment arrangements currently being negotiated.

Andy Well resource upgrade

THE DRILL SERGEANT: Doray Minerals has announced an increase and upgrade to the high-grade Wilber Lode resource at the 80 per cent-owned Andy Well gold project.

The combined Inferred and Indicated resource for the Wilber Lode now totals 680,000 tonnes at 15.1grams per tonne for a total of 331,000 contained ounces

”The aim of this resource update was to upgrade as much as possible of the existing Wilber resource from Inferred to Indicated classification, in preparation for detailed mining studies and delineation of a maiden mining reserve”, Doray Minerals managing director Allan Kelly said in the company’s announcement to the Australian Securities Exchange.

The Andy Well gold project is located approximately 45 kilometres north of Meekatharra, in Western Australia’s Murchison Region.

“This updated resource represents a small increase to the December 2011 total resource, however includes an 18 per cent increase to the indicated component of the Wilber Lode resource ounces, increasing it to 89 per cent of the total Wilber Lode resource.” Kelly said.

Drilling continues at Andy Well, testing for further extensions to the Wilber Lode resource.

High-grade Gold/Copper intercepts at Imperial

THE DRILL SERGEANT: Integra Mining has reported encouraging diamond drilling results from the recently discovered Imperial Prospect located in the Majestic area, part of the company’s Randalls gold project.

The diamond hole was drilled to provide structural information on the mineralisation controls on previously reported high-grade gold and copper intercepts, and has returned positive results including:

– 8.29 metres at 16.51 grams per tonne gold and 1.25 per cent copper, including 1.47 metres at 55.90 grams per tonne gold and 4.24 per cent copper;

– 1m at 5.40 g/t gold and 0.32 per cent copper; and

– 1m at 4.10 g/t gold and 0.02 per cent copper

The Imperial prospect is located approximately 500 metres northwest of the Majestic gold deposit

The Imperial prospect is part of the Monger Joint Venture between Integra (85 per cent) and Newcrest Operations (15 per cent).

Gold mineralisation is hosted within the same granodiorite unit hosting the Majestic gold deposit and appears to be associated with a similar series of porphyry dykes.

Results reported in February from the RC drill program completed in December 2011 indicate that the mineralisation at Imperial continues for at least 190 metres strike and remains open to the north and south and down dip.

Additional RC drilling to further test the continuity and strike extent of gold mineralisation at Imperial is on- going

Assay results from the series of RC drill holes are pending

Navarre strikes high-grade gold at Tandarra

THE DRILL SERGEANT: Navarre Minerals has hit a further high-grade drill intercept on the Tomorrow line of quartz reef at the Tandarra prospect, part of the company’s Bendigo North project, located north of Bendigo in Victoria.

The RC drilling intercept of one metre at 33.6 grams per tonne gold at a depth of 44 metres is contained inside a four metre interval grading 9.4 grams per tonne gold.

The latest intercept is situated approximately 160m north of the company’s best intercept to date of 34.4 grams per tonne gold over a 10 metre interval.

The Navarre also intersected further broad gold mineralisation of 25m at 0.8 g/t gold, including 6m at 1.9 g/t gold from 41m down hole.

Navarre is conducting a 25,000 metre RC drilling campaign at Tandarra targeting shallow gold-bearing quartz reefs and is seeking to build a mineral resource at the project by the end of 2012.

“We are encouraged by the broad zone of shallow mineralisation in RCT025 as it now links approximately 320 metres of wide zones of mineralisation in the RC results, which themselves are part of the 2.5 kilometres of confirmed strike established by previous AC drilling,” Navarre Minerals managing director Geoff McDermott said in the company’s announcement to the Australian Securities Exchange.

Navarre believes mineralisation at Tandarra is analogous to the Bendigo Goldfield, approximately 40kms to the south, insofar as nuggety high grade gold is dispersed throughout an envelope of lower grade material.

“We are particularly pleased by the high grade result in RCT050 as we expect to find high grade gold results as our drill density increases in this style of mineralization,” McDermott said.

The relatively shallow depth of the gold mineralisation it has identified so far has Navarre working to establish whether an open pit operation is feasible as a means of mining the high-grade gold within a broader envelope of mineralised material.

“Tandarra was identified by modern exploration techniques, which see through the covering sediments, and followed up by inexpensive scout AC drilling,” McDermott explained.

“Our challenge now is to define the major gold-bearing reefs near surface and to investigate the quartz reefs which repeat at depth, much as they do at Bendigo and other Victorian goldfields.”

Navarre Minerals said it expects to release more drill results from 25 RC holes at Tandarra that have been completed but await assay results, as well as further RC and diamond holes that have yet to be drilled as part of the current program.

Multiple REE discoveries at Mount Muambe

THE DRILL SERGEANT: Africa-focused resource company Globe Metals & Mining has announced the discovery of three new, substantial zones of rare earth mineralisation at the Mount Muambe REE – Fluorite project in Mozambique. By Mark Jones

In 2011, Globe completed 9,427metres of RC drilling at the Mount Muambe REE Fluorite project.

The final 4,050m of drilling focused on new REE targets in six separate zones.

Substantial REE discoveries were made in three of the zones.

Globe’s regional exploration manager for Africa, Michael Schultz, commented, “The three new REE discoveries are a fantastic outcome from the 2011 drilling program at Mount Muambe. Many of our holes show appreciable results with substantial width REE intercepts grading between 1.5% and 4% TREO.”

Highlights of drilling results include:

• 46m @ 2.6% TREO inc. 20m @ 3.3% TREO
• 49m @ 2.5% TREO inc. 20m @ 3.5% TREO
• 47m @ 1.7% TREO inc. 17m @ 2.4% TREO
• 60m @ 2.1% TREO inc. 24m @ 2.6% TREO
• 28m @ 2.1% TREO inc. 12m @ 2.9% TREO  

Schultz added: “The most exciting development is the fact that the majority of the REE drill intercepts are open at depth and hosted in carbonatite, the most dominant rock type in the crater. This clearly shows the potential to discover large tonnages of REE mineralisation.”

All substantial zones of REE mineralisation intersected remain open at depth and laterally.

A diamond and RC drill rig have mobilised to site to begin the substantial 2012 drilling program.

Detailed metallurgical test work will commence at the completion of the diamond drilling program.

Sirius scores gold multiple gold hits at Polar Bear

THE DRILL SERGEANT: Sirius Resources has claimed discovery of high-grade gold mineralisation in its first reverse circulation (RC) drilling program undertaken at the Earlobe prospect on the company’s 100 per cent-owned Polar Bear project in Western Australia.

Sirius said it had intersected gold mineralisation in a number of RC holes drilled beneath earlier shallow reconnaissance drill intersections carried out in in November 2011.

intersections in recent aircore and RC drilling. Source: Company


Key intercepts and highlights of the recent drilling include:

20 metres at 3.18 grams per tonne gold from 36 metres, including 2 metres at 26.6 grams per tonne gold from 36 metres; and

19m at 1.56 g/t gold from 46m, including 4m at 6.09 g/t gold from 50 metres.

The drilling also encountered a two metre zone exhibiting variable gold in repeat assays (1.4, 5.04 and 24.9 g/t gold from 82m), which the company said suggests nuggety gold could be present.

Sirius is of the opinion the distribution of the gold intersections on two lines of drilling at the Earlobe North zone suggests there are several gently to moderately east dipping lodes open down dip (to the east) and along strike of the drilling it has completed so far.

The company has taken encouragement from these results, as they are the first gold-focused RC drilling program to be conducted at Polar Bear and that the project is located between three major known goldfields.

The project neighbours the 10 million ounce Norseman camp 30 kilometres to the south, the 8 million ounce St Ives camp 60km to the north and the 2 million ounce Higginsville gold mine 20km to the north-northwest.

“It is very encouraging to make this discovery – it vindicates our belief in the Polar Bear project – a belief which led us in 2010 to purchase Barrick’s 80 per cent interest in the project to obtain full ownership,” Sirius Resources managing director Mark Bennett said in the company’s announcement to the Australian Securities Exchange.

“To achieve such results in the first RC drilling program, and also beneath transported sediments and unconformable Tertiary rocks, attests to the untapped prospectivity of the area, despite it being in the heartland of the Eastern Goldfields.”

Sirius said it intends to carry out follow up RC drilling to scope out the extent, orientation and continuity of the mineralisation once a drill rig can be sourced and drilling approvals obtained.

Ventnor hits deep mineralisation at Thaduna

THE DRILL SERGEANT: Phase 4 drilling being carried out by Ventnor Resources at the Thaduna prospect has hit deeper copper mineralisation.

The Thaduna prospect is situated on the company’s Thaduna and Green Dragon copper project located 170 kilometres north of Meekatharra, in the Doolugunna district of Western Australia.

The project sits 40km east of the Degrussa project of Sandfire Resources.

According to Ventnor a recent diamond drilled tail to extend a previous RC drill hole at the Thaduna prospect has intersected sulphide mineralisation observed over 14.0 metres from 250.6m to 264.6m down hole with chalcopyrite/bornite matrix mineralisation.

The company said this intersection represents a southerly down plunge extension to the main lode system which it considers to be evidence of an increase in grade and thickness with depth.

The core sample has been logged and cut, with half core samples having been submitted for assay.

“This is our deepest intersection to date and primary mineralisation has now been intersected at 200 metres vertical depth,” Ventnor Resources managing director Bruce Maluish said in the company’s announcement o the Australian Securities Exchange.

“This presents a compelling case to extend the current drilling campaign to investigate the potential below this intersection.

“Five additional deeper holes have been planned along strike; sites are being prepared for drilling to be undertaken during May.”
The planned additional holes will be RC pre-collars with diamond tails.

The company said the holes are being projected to intersect the lode system at 300m vertically below the surface.

Ventnor has now completed a total of 137 holes for 18,431m at Thaduna.

The Phase 4 drilling, which the company commenced in January 2012, was focused on Thaduna to extend existing RC holes terminating in mineralisation with diamond tails.
