Impact Minerals Reviewing Previous Exploration On Pilbara Gold Project

THE DRILL SERGEANT: Impact Minerals (ASX: IPT) is completing a review and synthesis of previous exploration data and mapping by the Geological Survey of Western Australia (GSWA).

Impact Minerals applied for nine new 100 per cent-owned Exploration Licences earlier this year, covering approximately 1,300 square kilometres of ground it considers prospective for conglomerate-hosted gold in the Pilbara region of Western Australia.

The company’s review of the GSWA material is focusing on what it believes to be the two most prospective conglomerate horizons within the Fortescue Group.

These are the conglomerates of the Hardey Formation that hosts the Beatons Creek resource (6.4 million tonnes at 2.7 grams per tonne gold for 558,000 ounces of gold) held by Novo Resources Corporation near Nullagine, and conglomerates at the base of the Mt Roe Basalt., which contains the recent gold discovery at Purdeys Reward-Comet Well by Novo Resources and Artemis Resources.

Impact said that field checking and previous mapping indicates prospective conglomerates occur over at least 90 kilometres of trend at or close to surface within the company’s licence applications, in particular to the west and east of Marble Bar as well as close to the Beatons Creek deposit near Nullagine.

West of Marble Bar, previous exploration in the district has highlighted gold occurrences associated with the conglomerate horizons on and along trend from Impact’s licence applications ELA45/4972 and ELA45/4971, where four main gold-bearing conglomerate occurrences with similar characteristics to those that occur within the Witwatersrand Basin of South Africa have been discovered.

“We were recently privileged to visit the Purdeys Reward-Comet Well area with Novo Artemis and have seen first-hand the reasons why it had not been discovered before, the potential scale of the discovery and also the difficulties of exploring and sampling for this style of deposit,” Impact Minerals managing director Dr Mike Jones said in the company’s announcement to the Australian Securities Exchange.

“It is evident that there is a wide range in size and distribution of gold within these conglomerates and it is this that has hampered previous exploration for this style of mineralisation.

“We are now determining the most appropriate sampling methodologies for our on-ground exploration which will commence in earnest on grant of the licences.”

Impact made its move to the Pilbara following the discovery of gold in conglomerates at the base of the Fortescue Group by Artemis Resources and its subsequent Joint Venture with Novo Resources Corporation.

Impact considers this discovery has indicated a breakthrough had been made in the search for conglomerate hosted gold deposits of a similar age to the Witwatersrand Basin of South Africa in the Pilbara.



Azure Minerals hits Outstanding Gold and Cobalt at Sara Alicia

THE DRILL SERGEANT: Azure Minerals (ASX: AZSDA) shouted from the rooftops to report it had encountered high-grade gold and cobalt mineralisation in the company’s first drilling program on its 100 per cent-owned Sara Alicia project, located in Sonora State, Mexico.

Azure Minerals said it had intersected a wide zone of near-surface, high-grade gold and cobalt mineralisation.

The company indicated the mineralised zone to be open in all directions.

The best gold intercept encountered was:

26.2 metres at 8.6 grams per tonne gold, including 12.6m at 14.9g/t gold.

The company claimed the drilling returned other, numerous high-grade gold assays, including: 66.2g/t gold, 33.9g/t gold, 28.1g/t gold, and 25.7g/t gold.

The best cobalt intercept came in at:

26.2m at 1.26 per cent cobalt, including 6.35m at 3.57 per cent cobalt.

Other high-grade cobalt assays, included 6.62 per cent cobalt, 4.24 per cent cobalt, 4.04 per cent cobalt, and 3.06 per cent cobalt.

“This maiden drilling campaign has exceeded our expectations and confirmed the presence of high-grade gold and cobalt mineralisation over significant widths,” Azure Minerals managing director Tony Rovira said in the company’s announcement to the Australian Securities Exchange.

“The spectacular cobalt grades in hole DSA-03 are up there with the highest I’ve ever seen and, encouragingly, the mineralisation starts at surface and remains open in all directions.

“These wide, high-grade zones host strong gold mineralisation consistently assaying in the range of 10 grams per tonne to 60 grams per tonne and cobalt grading from one per cent to six per cent.

“We believe there’s good potential for a high-value body of gold and cobalt mineralisation to be defined at Sara Alicia, and further exploration will be undertaken to identify the size potential.”


Tyranna Resources Announces Drilling at Greenwood Gold Prospect

THE DRILL SERGEANT: Tyranna Resources (ASX: TYX) reported the commencement of diamond drilling at the Greenwood gold prospect by the Western Gawler Craton Joint Venture.

The Greenwood prospect is located approximately 37km north of the Challenger Gold Mine and part of the larger Jumbuck Gold Project in the Northern Gawler Block of South Australia.

Tyranna Resources said that approximately 1,000 metres of diamond drilling is underway to follow up the company’s grass roots gold discovery at the Greenewood gold prospect where recent high-grade reverse circulation (RC) drilling results were reported including:

From scissor hole 020
22 metres at 4.03 grams per tonne gold from 50m, including 1m at 20.4g/t gold 51 to 52m, including 1m at 36.9g/t gold from 55 to 56m; and

Hole 031 into fresh rock (primary zone) 
10m at 5.16g/t gold from 31m, including 1m at 29.4g/t gold from 36m, including 1m at 7g/t gold from 37m.

Tyranna Resources outlined the reasons the JV had to back up this drilling program to include a follow up of recent RC drilling depth penetration difficulties and to extend depth extension of primary zone fresh rock where the recent pipe like structures were located.

The JV also hopes to gain accurate structural information to update the current resource model.

HQ sized core will be drilled to provide samples for geological, metallurgical and mining studies.

“Tyranna completed a highly successful drilling program in the first half of 2016, which resulted in the discovery known as the Greenewood gold prospect located within the Jumbuck gold project,” the company said in its ASX announcement.

“This is the first grass roots discovery in the Jumbuck gold project area in over 15 years.

“After interpretation of the RC results of recent exploration drilling by Tyranna geologists, it became apparent that the next logical step was to commence the diamond drilling program to improve the understanding of the structural constraints of the mineralisation.”

Tyranna Resources is manager of the Western Gawler Craton Joint Venture, which includes WPG Resources (ASX: WPG) (TYX 75% – WPG 25%) and Coombedown Resources Pty Ltd.



Tando Resources Encounters Quartz Bore Massive Sulphides

THE DRILL SERGEANT: Tando Resources (ASX: TNO) announced the intersection of massive sulphides in the first drill hole carried out at the Balla Balla prospect that forms part of the company’s 100 per cent-owned Quartz Bore project, in the Pilbara region of Western Australia.

Tando Resources is running the maiden drill program at Quartz Bore with the aim of generating targets below, and along strike from, high-grade zinc-copper mineralisation defined in historical drilling at the Balla Balla prospect.

To that end, hole QBDD0001 is testing for extensions of mineralisation below and adjacent to historical drillholes:

7.6 metres at 4.86 per cent zinc, 2.13 per cent copper and 1.56 per cent lead, including 2m at 13.71 per cent zinc; and

3.5m at 5.68 per cent zinc, 0.39 per cent copper and 2.03 per cent lead.

5m at 3.15 per cent zinc.

Tando claimed it had intersected two sulphide-bearing zones containing greater than 10 per cent sulphide minerals 326.5m (extending for 9m downhole) and 342.5m (extending for 5m), including lengths of massive sulphide (containing 80-90% sulphide minerals) up to 1.4m in length.

The company said the style of mineralisation encountered had given it encouragement that downhole surveys will be able to detect extensions to these zones due to the different petrophysical properties of their constituent sulphides.

“To intersect substantial sulphides in our first drill hole is very encouraging,” Tando Resources managing director Bill Oliver said in the company’s announcement to the Australian Securities Exchange.

“The focus of this initial program is to validate high-grade historical drilling results, and this intersection confirms our belief that the Quartz Bore project hosts significant zinc-copper mineralisation.

“We now look forward to drilling further holes to test other extensions to mineralisation.”





Gold Road Yamarna_May2017 (300x225)

Good News is Best News for Gold Road Resources

THE INSIDE STORY: Gold Road Resources’ (ASX: GOR) is determined to repeat the Gruyere gold discovery from its substantial 6,000 square kilometre Yamarna Belt tenement holding in Western Australia.

Having negotiated the Gruyere Joint Venture (GJV) deal with Gold Fields Ltd, which the Diggers & Dealers Mining Forum declared, the ‘Deal of the Year’, Gold Road Resources embarked on a $30 million greenfield exploration drilling program.

This recent drilling was centred on the Wanderrie and Corkwood Camps, located within the company’s 100 per cent-owned North Yamarna tenements.

This included RC and diamond bedrock testing of prioritised highest-ranked targets, and infill definition of gold anomalies identified through regional aircore drilling completed while Gruyere studies were being completed.

Of interest was developing an improved understanding of these targets with Santana and Satriani (Wanderrie Camp), and Ibanez (Corkwood Camp) receiving priority attention.

Broad spaced drilling confirmed gold bedrock mineralisation along the main mineralised shear through the Santana and Satriani prospects, which form part of a continuous 11-kilometre-long mineralised corridor known as the Wanderrie Supergroup Trend.

Best Wanderrie mineralised intersections included:

Satriani RC

2m at 14.74g/t gold from 73m;

Santana RC

1m at 17.73g/t gold from 68m; and


5m at 2.03g/t gold from 108m.

Similar bedrock drilling testing the Ibanez prospect at the Corkwood Camp returned intersections of:

Ibanez DDH

8.2m at 11.63g/t gold from 229.67m, including 3.33m at 27.48g/t gold from 232.26m; and

Ibanez RC

10m at 28.67g/t gold from 240m, including 2m at 136.57g/t gold from 240m.

Each new drilling campaign at all three prospects encouraged the company, with planning now underway for systematic framework drilling to definine greater extents of the mineralised systems.


Anticipated results from this extended work will provide a deeper understanding of each prospect’s potential as the company aims to progress at least one of these areas to advanced infill drilling in 2018.

Other work completed on the North Yamarna tenements included aircore definition of a five-kilometre southern continuation of the Wanderrie Supergroup Trend through the Gilmour and Morello prospects, where early bedrock drilling intersected gold mineralisation.

Gold Road interprets Supergroup Trend to be the southern continuation of the Attila‐Alaric Trend, which already hosts 420,000 ounces of gold in Mineral Resources.

The Attila‐Alaric Trend continues over 30 kilometres further south to the Yaffler and Toppin Hill prospects on the company’s South Yamarna Joint Venture tenure, a 50:50 Joint Venture with Sumitomo Metal Mining Oceania Pty Ltd.

The JV’s recent exploration efforts at South Yamarna centred on selective testing of priority targets, particularly the Breelya‐Toppin Hill, Spearwood and Kurrajong Camp Scale targets, where a total of 12 Reverse Circulation (RC) and 103 aircore drill holes were carried out.

Bedrock mineralisation was intersected at Yaffler South, in the Breelya‐Toppin Hill Camp, piquing the JV’s interest by delineating a thick mineralised shear zone close to the contact of a dolerite with a sedimentary unit, which it is confident can be identified in magnetics.

A strike length of 1.4km of mineralisation has been identified to date, providing room for follow‐up drilling that is pencilled in, at this stage, for next year, enhancing the JV’s portfolio of advanced drilling targets.

Best bedrock intersections at Yaffler South, included:

2m at 4.34g/t gold from 142m; and

15m at 0.68g/t gold from 40m, including 1m at 5.84g/t gold from 49m.

A further program, consisting 103 aircore holes was carried out at the Kingston North target, designed to infill and extend anomalism delineated by drilling completed last year.

The drilling confirmed the Kingston North target includes an area of structural complexity with north to north‐west striking shear zones being interpreted from geophysical data.

The company’s geological interpretation of the Kingston North results indicates anomalous gold mineralisation associated with zones of stronger shearing.

These anomalous zones are being incorporated into a detailed geological and structural re‐interpretation that will form the basis for follow up drilling.

“The drilling we have completed this year has provided some extremely encouraging results,” Gold Road Resources executive director ‐ exploration & growth Justin Osborne told The Resources Roadhouse.

“The Gruyere project team has been keeping the project build right on schedule, which has allowed us to focus on speeding up our exploration programme across the broad Yamarna Belt.”

Progress of the Gruyere gold project is happening without much fanfare or headlines, which Gold Road Resources is very pleased about.

As exciting as it is to be building a project of the scale of Gruyere, Osborne said the company was holding the advice of chairman Tim Netscher in high regard.

“It’s great having somebody with the experience of Tim as our chairman and working so close with the Board and the Steering Committee,” Osborne said.

“He’s been through all this before and he knows that the most common news you expect to hear during development of a project is bad news – so we are more than happy not to be generating headlines as the project ticks along on schedule.”

It has been a case of so far so good for the Gruyere gold project, which has quietly progressed, on schedule and budget, under the stewardship of JV partner Gold Fields.

The right boxes continue to be ticked with engineering, procurement and construction (EPC) contractor Amec Foster Wheeler Civmec Joint Venture (ACJV) having commenced process plant construction.

A concrete batch plant was also commissioned, allowing the ACJV to complete the first concrete pour in the carbon‐in‐leach (CIL) area.

Fabrication of the steel plate for the CIL plant tanks, the first of the major components required for the process plant, commenced in Civmec’s Henderson facility south of Perth, which will complete all of the steel fabrication from 100 per cent Australian sourced steel.

Bulk earthworks contractor MACA has completed clearing of the process plant site, construction of the Gruyere airstrip and Gruyere main access road, and has also commenced clearing for the Stage 1 open pit, having completed clearing for the Tailings Storage Facility.

MACA has also started initial construction works for the installation of production and monitoring bores for the Yeo borefield, which will supply the mine and process plant.

A strong field of companies tendering for the mining services contract has been whittled down to a short list of three.

It is expected this contract will be finalised by the end of the year, allowing the successful party to start mobilising to site in the March 2018 quarter.

There may not be as many months left in the year as there were, but Gold Road shows no sign of slowing down before Christmas.

Work on the North Yamarna tenements will include diamond and RC drilling at Ibanez targeting stacked high‐grade lode structures to allow further advanced infill drilling.

On the Gruyere JV, Gold Road expects to report a maiden Mineral Resource estimate for YAM14 in early 2018.

Alaric and Attila pre‐feasibility studies are near completion which if positive will allow reporting of first Ore Reserves also early in 2018.

A high level conceptual mining study for the northern higher-grade zone of Gruyere is also underway to assess potential for future drilling in this area of the deposit.

The South Yamarna JV will conduct drilling at Yaffler, subject to pending assays, in concert with development of a structural and geological map for Kingston North to guide future bedrock testing.

Venturex Resources’ Review Identifies Conglomerate Gold Occurences

THE DRILL SERGEANT: Venturex Resources (ASX: VXR) completed a review of previous exploration at the Mays Find prospect, within the company’s Whim Creek copper-zinc project, Project located west of Port Hedland in the Pilbara region of Western Australia.

Venturex Resources said the review had revealed broad gold- in-soil anomalies associated with outcropping basal conglomerate, and armed with such information declared the identification of gold occurrences associated with the Lower Fortescue Group conglomerates.

Venturex identified the gold occurrences during recent field exploration activities, which were supported by the review of historical gold exploration data at Mays Find.

The company explained the historical data is from soil sampling carried out in 2007 by Straits Resources, the previous owner of the Whim Creek project, which collected soil samples over Mays Find as part of a broader exploration program aimed at discovering additional base metal deposits.

These soil samples were collected every 50 metres along 200m spaced lines over a strike length of 5.2 kilometres, then assayed for a range of elements including gold.

Although the assays produced anomalous results of up to 52ppb gold, there was no further commentary or follow-up work undertaken at the time on the gold potential of the area.

“As part of the historical gold review, the company discovered 57 rock chip samples collected from the Mays Find area in 2014 that had not been assayed for gold,” Venturex Resources said in its ASX announcement.

“Many of these samples were described as various sedimentary rocks including conglomerate.

“The laboratory pulps derived from these rock chip samples stored at the company’s Whim Creek project have been retrieved and sent to the laboratory for a gold fire assay.

“The results from this work will be used to determine future exploration methods to be employed to pursue the conglomerate-gold potential at Mays Find.”

Venturex outlined upcoming work to include additional detailed mapping of the conglomerate and sedimentary units as well as stream sediment sampling and in-fill soil and rock sampling along the entire five to six kilometre length of the Mays Find area.

This work will likely be supported by metal detector traverses of the scree slope below the conglomerate outcrops.



Rox Resources Commences Mt Fisher Aircore Drilling

THE DRILL SERGEANT: Rox Resources (ASX: RXL) commenced an aircore drilling program at the company’s Mt Fisher gold project, north of Leonora in Western Australia.

Rox Resources indicated the drilling campaign at Mt Fisher is to comprise approximately 112 holes for 7,500 metres, with the main focus being the Dam, Damsel, Nile and Shiva prospects where strong drilling results have previously been received.

Rox explained the gold target areas lie to the west of the Fisher East nickel belt and that the aim of the drilling program is to complement the company’s previous successful drilling results, so that more coherent geochemical targets can be defined for follow-up RC and diamond drilling.

Rox believes the Dam-Damsel-Shiva area has similarities to the 3.6 million ounce Bronzewing camp some 75 kilometres to the southwest, and is using the extensive knowledge base that was built up in the 1990’s and 2000’s regarding Bronzewing and the Yandal Belt in its exploration program design.

“We have had these high-priority targets identified for some time, and are now pleased to be able to progress to drilling and target significant gold mineralisation,” Rox Resources managing director Ian Mulholland said in the company’s announcement to the Australian Securities Exchange.

“The sheer amount of gold in the regolith in this area is compelling evidence of a much bigger and richer gold source at depth.”





Millennium Minerals Continues Run Of Results From Nullagine

THE DRILL SERGEANT: Millennium Minerals (ASX: MOY) reported further results from exploration at the company’s Nullagine gold project in the Pilbara Region of Western Australia.

Millennium Minerals said the latest results have provided extra support to its plans to increase production and mine life.

Recent drilling has returned intercepts from Au81 West, part of the Golden Eagle Mining Centre.

Millennium said the drilling had also highlighted potential to extend the historical pits at Little Wonder and Roscoes Reward, part of the Camel Creek Mining Centre.

The company assed that its recent review of conglomerate-hosted gold potential at Nullagine has delivered initial positive results, confirming the presence of gold mineralisation within the Dromedaries – two conglomerate-capped ridges located immediately east of the Golden Eagle plant.

All of this follows the gold discovery at Redbeard, part of the Yates trend, and high-grade intersections including visible gold in core at Bartons Underground announced earlier this week.

“These latest drilling results – which traverse 40 kilometres from the south-west to the north-east of our Nullagine tenements – demonstrate the outstanding discovery potential within the Middle Creek Mineralised Corridor,” Millennium Minerals chief executive Peter Cash said in the company’s announcement to the Australian Securities Exchange.

“Millennium made the decision to dramatically expand our exploration efforts in 2017, increasing our exploration budget to $22 million for the year.

“Since then, we’ve hit high-grade gold at almost every target we’ve tested, with results spanning both open pit and underground, as well as oxide and fresh ore targets.

“In addition, the results of the conglomerate review are highly promising, confirming the presence of gold mineralisation within the Dromedaries and suggesting a possible correlation between the mapped conglomerate at Nullagine and some of the extensive geochemical anomalism in the surrounding area.

“Collectively, this puts us in an exceptionally strong position to deliver on our growth objective, aimed at delivering a five-year mine life at Nullagine based on production of 100,000 ounces per annum.”



Calidus Resources Identifies New Gold Targets

THE DRILL SERGEANT: Calidus Resources (ASX: CAI) completed an initial review of the company’s recently expanded land holdings across the Warrawoona gold project in the East Pilbara district of the Pilbara Goldfield in Western Australia.

Calidus Resources said the review had generated numerous high priority gold targets.

Calidus received ASTER (Advanced Spaceborn Thermal Emission and Reflection Radiometer) imagery from across the wider Klondyke area.

The company explained this technology is used to map lithology and hydrothermal alteration zones and identify signatures for gold exploration allowing it to highlight target hydrothermal alteration zones of potentially economic gold mineralisation to discriminate them from altered zones with lower potential.

The imagery consists of 14 data channels covering ranges of visible, near infrared, shortwave infrared and thermal infrared regions of the electromagnetic spectrum.

Using this method, Calidus aims to discern the boundary between altered and unaltered rocks based on alteration minerals and mineral assemblages.

This work is currently being undertaken in conjunction with geological and structural mapping to assist with the ranking of exploration targets.

The company carried out exploration target ranking of the newly acquired Novo tenements, from which it has identified the Trump and Cutty Sark prospects, located approximately 7.5 kilometres to the west of the main Klondyke resource area, as highly ranked near surface high-grade gold targets.

Calidus also completed a regional targeting exercise to confirm a number of potential gold-hosting conglomerate targets on its granted tenements and applications.

During an initial field trip that was aimed at locating the contact horizon and determine the extent of basal Mt Roe formations outcropping on tenement application ELA45/4556 close to Marble Bar, gold nuggets were confirmed.

“With a growing resource base at Klondyke, to have such a suite of exciting regional projects highlights the large potential of this goldfield,” Calidus Resources managing director Dave Reeves said in the company’s announcement to the Australian Securities Exchange.

“With the assistance of the CSIRO, we are getting a lot clearer picture of ore shoot control and methods that will allow us to rapidly and inexpensively explore the majority of our landholding.

“This, combined with extensive conglomerate outcrops, which are readily accessed from existing roads, provides Calidus with numerous high ranking targets for the year ahead.

“With such a large amount of opportunity, we have recently employed the highly experienced Brenton Siggs as Exploration Manager to accelerate regional greenfields exploration of our wider tenure whilst our current team continue to focus on resource increase around known deposits.”



ST George Mining Extends Mt Alexander Drilling

THE DRILL SERGEANT: St George Mining (ASX: SGQ) has upped the ante by escalating diamond drilling underway at the company’s Mt Alexander project in Western Australia.

St George Mining said the decision to advance the program followed the recent intersection encountered by drill hole MAD71.

The company now has DHEM being carried out in all drill holes completed to date in the current drill program, which it believes will assist in identifying further mineralisation around the drill holes.

Additional drill holes are currently being designed at the Stricklands prospect, to follow-up on the MAD71 intersection of magmatic nickel-copper sulphides.

The mineralisation in MAD71 is open to the west and north, and is associated with strong SAMSON and SQUID EM anomalies that remain largely untested in this area.

A strong magnetic anomaly also covers this area, which St George considers likely to represent prospective ultramafic stratigraphy.

A diamond drill rig that is currently on site will continue drilling at Mt Alexander 24 hours a day, 7 days a week until the Christmas break.

A second drill rig has now also arrived at the company’s 100 per cent-owned East Laverton project to drill three, strong late-time conductors at the Windsor nickel sulphide prospect.

“The thickness of the ultramafic and the nickel-copper sulphides intersected at Stricklands is supportive of further significant mineralisation being intersected at this prospect,” St George Mining executive chairman John Prineas said in the company’s announcement to the Australian Securities Exchange.

“The target area for further drilling is to the west and north of MAD71 where the SAMSON and SQUID EM anomalies remain largely untested and a strong magnetic anomaly also indicates further prospective ultramafics.

“We are excited to be able to fast-track this follow-up drilling to the significant intersection in MAD71.”
