Peak Resources delivers Ngualla PFS

THE DRILL SERGEANT: Peak Resources (ASX: PEK) has finalised the Preliminary Feasibility Study (PFS) for the company’s 100 per cent-owned Ngualla rare earth project in Tanzania.

Peak said the PFS has confirmed Ngualla to be an economically robust project at a base case production rate of 10,000 tonnes per annum of separated high-purity rare earth oxides (REO).

The Study has concluded the Ngualla project to have a Net Present Value (NPV) of US41.310 billion pre-tax and royalties (US$1.005 billion NPV post tax and royalties) with a 39 per cent Internal Rate of Return (post tax and royalties).

The project could reach payback in its third year of production producing an average annual operating free cash flow of US$174 million per annum for 58 years pre-tax and royalties (US$116 million per annum post tax and royalties).

When leveraged to rare earth prices, 83 per cent of Ngualla’s forecast revenue will be derived from the high value, high demand neodymium – praseodymium and mid and heavy rare earth products the company anticipates producing.

According to Peak, the Study applied conservative price assumptions with an average product price for the Ngualla rare earth composition of US$29.29/kg for high purity separated REO.

The project is also well-leverage in regards to any further increases in rare earth prices with potential for after tax and royalty NPV to increase to US$ 1.608 billion for an additional 25 per cent increase in prices.

The Study also came in with low capital and operating costs, reducing the cost predicted in a Scoping Study from last May by US$91 million to US$282 million.

Operating costs came in at US$11.74 per kilogram high purity separated rare earth oxide products over the life of mine, which is projected at 58 years.

“We are extremely happy with the results from the PFS,” Peak Resources managing director Darren Townsend said.

“These show the project to be robust with an extremely long mine life and attractive free cash generation.

“From the detailed work completed we have identified opportunities for potential further operating cost reductions through the optimisation of the processing circuits and additional reagent recycling.

“With the positive outcome of the study we will step up our discussions with a number of potential strategic financial partners with a view to rapidly progressing the development of the Ngualla project.”

Sheffield Resources doubles Thunderbird Resource

THE DRILL SERGEANT: Sheffield Resources (ASX: SFX) has released an updated mineral resource for the Thunderbird deposit at the company’s Dampier heavy mineral sand (HMS) project in the Canning Basin region of Western Australia.

The total Mineral Resource for Thunderbird now stands at:

2.62 billion tonnes at 6.5 per cent heavy minerals (HM) Measured, Indicated and Inferred, for 170 million tonnes of contained HM.

The latest calculation is compares favourably to the previous December 2012 maiden mineral resource for the deposit of:

1.37 billion tonnes at 6.1 per cent HM (Indicated & Inferred) at 2 per cent HM cut-off.

The resource includes a coherent high-grade zone (at 7.5 per cent HM cut-off) of 740 million tonnes at 12.1 per cent HM (Measured, Indicated and Inferred) containing 6.8 million tonnes of zircon, 2.1 million tonnes of high-titanium leucoxene, 1.9 million tonnes of leucoxene and 25 million tonnes of ilmenite.

“The Thunderbird deposit is one of the largest accumulations of zircon in the world,” Sheffield Resources managing director Bruce McQuitty said in the company’s announcement to the Australian Securities Exchange.

“The contained zircon of the Total Resource stands at 14.3 million tonnes, more than twice that of the previous 2012 resource estimate.

“The deposit also contains a globally significant quantity of ilmenite.

“The key to the deposit is the extensive high-grade zone, which features exceptionally high in-situ grades of 0.92 per cent zircon and 3.4 per cent ilmenite.

“Zircon and ilmenite are expected to be the most important products by value and volume, respectively.

“Importantly, leading industry consultants TZMI have confirmed that the Thunderbird products will achieve wide acceptance in the broadest market sectors.”

Sheffield is currently running a Scoping Study over Thunderbird, due for completion in the next few weeks, which will focus on scheduling initial production from this high-grade zone during early production years.

The company said the high in-situ valuable heavy mineral (VHM) grades for this zone of 0.92 per cent zircon, 0.29 per cent high-titanium leucoxene, 0.25 per cent leucoxene and 3.4 per cent ilmenite place Thunderbird within the top tier of HMS deposits globally.

“This resource update is an outstanding result for our shareholders and a great achievement by our exploration team who have built a resource inventory of global scale during the last three years.”

“The mineralisation at Thunderbird remains open in all directions.

“Sheffield’s 2014 drilling campaign will target extensions to the deposit.”

Blackham confirms shallow high grades at Galaxy

THE DRILL SERGEANT: Blackham Resources (ASX: BLK) has received the first results from initial drilling being carried out on the Galaxy deposit at the company’s Matilda gold project in Western Australia.

Blackham’s resource inventory at the Matilda gold project currently stands at 24 million tonnes at 1.9 grams per tonne gold for 1.4 million ounces of gold.

 

Source: Company announcement

 

The company explained this is the first drilling it has conducted at Galaxy, which has a resource – based on previous exploration – of 52,000 ounces of gold.

The program was designed to test potential near-surface extensions of mineralisation at Galaxy as well as potential new resource areas at Mentelle and Matilda.

So far assays have been received for the first 16 holes of the program, which were drilled at Galaxy, while further results are expected from additional drilling at Mentelle and Matilda in the coming weeks.

The drilling has so far achieved a number of high-grade results, including:

GARC0011:
4 metres at 19.6 grams per tonne gold from 37 metres, including 1 metre at 43.3 grams per tonne gold from 37 metres;

GARC0013:
2m at 9.58g/t gold from 15m; and

GARC0016:
2m at 12g/t gold from 9m.
 
The company claims these widths and grades are consistent with historical drilling, while indicating mineralisation intersected in GARC0011 is outside the current resource.

Blackham considers this demonstrates potential for identifying new lodes and greatly improving mining economics.

The company is continuing to interpret the results, although it is confident, at this stage, that further drilling is warranted to delineate the additional lodes identified in this drilling in order to confirm the orientation of high-grade mineralisation.

“The Galaxy deposit is a modest sized resource although strategically important due to its high-grade and expression at surface,” Blackham Resources said in its ASX announcement.

“The company envisages future drilling to involve a combination of exploration for new lodes as well as infill drilling to facilitate a new estimate with a higher degree of confidence.”

Gold Road hits broader, higher grades at Gruyere

THE DRILL SERGEANT: Gold Road Resources (ASX: GOR) has received assay results for the remaining 26 drillholes from the recent RC drilling program conducted on the Gruyere prospect on the Dorothy Hills Trend in Western Australia.

Gold Road said the drilling has returned the best RC intersections so far at the Gruyere prospect with wide zones of consistent higher‐grade mineralisation intersected in two holes.

14GYRC0034:
91 metres at 1.86 grams per tonne gold from 69 metres; and

14GYRC0033:

33m at 1.38g/t gold from 37m, and 47m at 1.53g/t gold from 73m.

The company said these result have confirmed its interpretation of southerly plunging higher grade shoots in the Gruyere mineralised system.

Best gold intercepts reported from one‐metre sampling from new assays received (at 0.5g/t gold cut‐off, minimum two metre mineralised intersection) included:

14GYRC0034:
91m at 1.86g/t gold from 69m, including 58m at 2.27g/t gold from 70m.

14GYRC0033:
3m at 3.17g/t gold from 31m, including 2m at 4.46g/t gold from 51m;

33m at 1.38g/t gold from 37m, including 28m at 1.53g/t gold from 42m; and

47m at 1.53g/t gold from 73m, including 14m at 1.93g/t gold from 87m, and 16m at 1.7g/t gold from 104m.

14GYRC0037:
2m at 3.33g/t gold from 48m; and

19m at 2.08g/t gold from 53m, including 12m at 2.82g/t gold from 59m.

14GYRC0032:
26m at 1.49g/t gold from 75m, including 21m at 1.66g/t gold from 79m.

14GYRC0039:
13m at 1.42g/t gold from 14m, including 10m at 1.67g/t gold from 16m, and 10m at 1.69g/t gold from 30m.

14GYRC0004:
11m at 1.82g/t gold from 16m, including 4m at 3.38g/t gold from 22m.

14GYRC0008:
15m at 1.23g/t gold from 7m, including 7m at 1.89g/t gold from 101m.

“These higher grade intercepts support our interpretation of the system,” Gold Road executive chairman Ian Murray said in the company’s announcement to the Australian Securities Exchange.

“Together with the deep (>500m) diamond hole (14GYDD0008), which we reported previously, we are proving that the Gruyere deposit is not just a very large gold system, but one which also has the potential to host high‐grade shoots.”

Gold Road has a second phase of infill drilling planned for the main prospect area to assist with resource modelling.

The company is progressing on detailed geological interpretation and modelling to improve its overall understanding of the Gruyere prospect mineralisation to enhance local and regional exploration targeting, and to provide the basis for resource modelling activities.

West African intersects consistent high-grade gold

THE DRILL SERGEANT: West African Resources (ASX: WAF) has received further gold results from a 5,000 metres reverse circulation (RC) drilling program at the Mankarga 5 deposit located on the Tanlouka permit, which is part of the company’s Boulsa project, in Burkina Faso.

The company said the results represent the conclusion of the shallow RC program at the Mankarga 5 deposit, which it has carried out since acquiring TSX-V listed Channel Resources less than two months ago.

The results cover more than one kilometre of strike on the central and northeast portions of the deposit, with highlights including:

TAC0045:
9 metres at 1.44 grams per tonne gold from 48 metres;
 
TAC0048:
12m at 8.82g/t gold from 38m, including 9m at 11.35g/t gold;

TAC0050:
8m at 5.69g/t gold from 35m, including 1m at 41.51g/t gold;

TAC0051:
14m at 2.42g/t gold from 9m, including 1m at 21.22g/t gold;

“We are very pleased with the final results from the shallow RC drilling program at Mankarga 5,” West African Resources managing director Richard Hyde said in the company’s announcement to the Australian Securities Exchange.

“The program has been very successful with consistent high-grade mineralisation intercepted along two kilometres of strike.

“The new data will result in an increase in the grade of oxide mineralisation which will be reported in the updated resource estimate for the Mankarga 5 deposit later this month.”

West African indicated it still has a program of deep diamond drilling currently underway in the south-western portion of the deposit, with drill hole TAN14-DD03 nearing completion.

Test work has commenced in Perth on samples from the four metallurgical diamond holes, which the company anticipates will determine expected recoveries from heap leach processing.

It is expected the drilling programs, in conjunction with a reinterpretation of the Mankarga 5 deposit, will lead to a resource update towards the end of this month.

The company is confident the combination of the results of the work programs will enable it to complete a Preliminary Economic Analysis (PEA) and Scoping Study in the first half of 2014.

Prospect Resources confirms continuation of Prestwood mineralisation

THE DRILL SERGEANT: Prospect Resources (ASX: PSC) has received results from an ongoing maiden six hole RC drill program being carried out at the company’s Prestwood gold mine in Zimbabwe.

Prospect claims the results it has achieved so far have confirmed the continuation of gold mineralisation below the historic mine.

Reef is shown to extend to the theoretical 6 Level. Source: Company
announcement

 

Three of four holes the company has drilled to date have intersected the Prestwood Reef down dip of historic workings, to 195 metres below surface

The company is currently drilling the fifth hole of the program.

Assay have been received from the first hole, BPC001 with results including:

A primary intercept of the Prestwood Reef of 9.23 grams per tonnes gold over 1m, at 153m (130m vertical);

An interception of the Upper Reef of 1.1g/t gold over 1m, at 120m; and

Sheared Monzonite contact at 1.1g/t gold over 1m at 107m.

“The drill program is designed to prove continuity of the historically mined Prestwood Reef along strike and down dip, and identify parallel zones of mineralisation plus identify potential targets for open-pit operations,” Prospect Resources said in its ASX announcement.

The company explained that, in conjunction with the drilling program, it has carried out other activities including the erection of exploration head-gear over the Prestwood Main Shaft with the mine now dewatered to 2 Level.

“Once shaft rehabilitation is complete, underground drilling for parallel reefs is planned,” the company said.

“Evidence of parallel reefs is supported by a ground magnetic survey completed in January plus existing artisanal surface mining.”

Prospect Resources considers the final results of the drill program and the fast track shaft rehabilitation and sampling has the company well placed to bring its first high-grade gold mine into production.

Prospect also has access to toll treating facilities lees than 25 kilometres from of the Prestwood mine.

Orion Gold encounters wide Fraser Range nickel

THE DRILL SERGEANT: Orion Gold (ASX: ORN) has received the first analytical results from its 2014 RC drilling program at the Peninsula project, located within the company’s Fraser Range nickel-copper-PGE project in Western Australia.

Orion drilled holes OPRC008, 009 and 010 in the eastern portion of the HA2 prospect to test an anomaly identified in a recently completed, trial IP survey.

announcement

 

The holes intersected a mafic gabbro below a cover of recent sediment, encountering fresh gabbro containing finely disseminated sulphides from approximately 45m depth to the end of the holes.

The holes ended in mineralisation and the mineralisation remains open in all directions.

Highlights from the results of all drilling included:

OPRC008:
80 metres at 0.11 per cent nickel, 0.05 per cent copper and 0.01 per cent cobalt from 44 metres, including 12 metres at 0.22 per cent nickel, 0.11 per cent copper and 0.02 per cent cobalt from 52 metres; and

8m at 0.06 per cent nickel and 0.01 per cent cobalt from 132m;

OPRC009:
47m at 0.08 per cent nickel, 0.02 per cent copper and 0.01 per cent cobalt from 44m;
 
13m at 0.07 per cent nickel, 0.02 per cent copper and 0.01 per cent cobalt from 138m;

10m at 0.07 per cent nickel and 0.04 per cent copper from 170m; and

6m at 0.10 per cent nickel, 0.05 per cent copper and 0.01 per cent cobalt from 190m.

OPRC010:
18m at 0.06 per cent nickel, 0.02 per cent nickel and 0.01 per cent cobalt from 38m; and

50m at 0.09 per cent nickel, 0.04 per cent copper and 0.01 per cent cobalt from 100m, including 10m at 0.14 per cent nickel, 0.07 per cent copper and 0.01 per cent cobalt from 116m.

Orion indicated a sample within the oxide zone from between 12 and 13 metres in OPRC008 had returned 0.08 grams per tonne platinum and 0.28g/t palladium.

The company said that although this result is from an isolated anomalous sample within the weathered zone, it provides further encouragement PGE mineralisation may also be present within the intrusive complex.

“These results confirm that our systematic targeting process is successfully leading us to the right areas in the right rocks,” Orion Gold managing director Errol Smart said in the company’s announcement to the Australian Securities Exchange.

“The company is strongly encouraged by these wide mineralised intersections which provide the first drilling evidence that the northern extent of the Fraser Range Belt contains substantial nickel-copper metal endowment in mafic intrusive rocks.

“These intersections represent some of the widest sulphide nickel-copper intersections drilled within the Fraser Range Belt.

“We await the remainder of assays together with downhole EM and petrographic results with anticipation.”

Orinoco drill review expands Brazil mineralisation

THE DRILL SERGEANT: Orinoco Gold Limited (ASX: OGX) has identified a number of historical drill intercepts, which it says point to a substantial extension of the known mineralisation at the Sertão gold mine in central Brazil.

Orinoco is acquiring 100 per cent of the Sertão gold mine gold rights from Troy Resources (ASX: TRY).

Since it first announced the acquisition, Orinoco has made considerable progress in advancing the Sertão project, which is located in the Faina greenstone belt close to the company’s Faina goldfields project.

The review has determined shallow oxide mineralisation remains open along strike from the existing open pit with results of:

2.65 metres at 22.43 grams per tonne gold from 6 metres; (GVD185)

7m at 4.85g/t gold from 8m; (SRB87)

6m at 6.64g/t gold from 12m; (SRC134)

High-grade intersections beneath the open pit highlight extensions of the Sertão mineralised structure including:

0.33m at 119.60g/t gold from 259.15m; (GVD080)

0.7m at 48.26g/t gold from 72.4; (GVD029)

0.62m at 22.97g/t gold from 92.26m; (SRD14)

6m at 2.09g/t gold from 75m; and (SRB130)

1m at 32g/t gold from 93m. (SRC141)

Orinoco is now reviewing the data to ascertain if JORC Code-compliant resources can be calculated from the existing drilling results.

Following the completion of this exercise, the company expects an exploration program will be planned to either delineate or increase the resources at Sertão with the aim of establishing a near-term production centre at Sertão as part of the broader development of the Cascavel gold project.

“These impressive historical drilling results add significant weight to our regional strategy at Sertão and Cascavel,” Orinoco Gold managing director Mark Papendieck said in the company’s announcement to the Australian Securities Exchange.

“The main driver for the Sertão acquisition was logistical and strategic impetus in accelerating the Cascavel development, however the strength of these results shows that Sertão could itself be a significant contributor to a regional production hub.

“We believe there is an opportunity to establish a JORC compliant resource at
Sertão in the short term which would strengthen the overall picture in terms of high-grade gold production opportunities in this region.”

Navarre encounters mixed bag at Eclipse porphyry prospect

THE DRILL SERGEANT: Navarre Minerals (ASX: NML) has achieved encouraging copper and gold results from a recent shallow drilling program at the company’s 100 per cent-owned Eclipse copper-gold prospect.

The prospect is located 300 kilometres northwest of Melbourne in the Miga Arc copper belt.

The shallow drilling returned shallow copper and gold up to 2.8 per cent copper and up to 3.3 grams per tonne gold while indicating secondary (chalcocite) copper approximately 30m from surface.

Copper grades better than 1 per cent copper were recorded in six of seven holes received to date, with RC drill results including:
 
RCBR0001:
5 metres at 1.8 per cent copper, including 1m at 2.8 per cent copper within 23m at 0.7 per cent copper from 30m.

RCBR0002:
1m at 1.4 per cent copper and 1m at 1.3 per cent copper within 29m at 0.5 per cent copper from 29m.

RCBR0003:
1m at 1.6 per cent copper within 9m at 0.4 per cent copper and 0.8 grams per tonne gold, from 28m;

45m at 0.4g/t gold from surface, including 1m at 3.3g/t gold;

10m at 1 per cent zinc from 32m;

16m at 1.5 per cent lead from 25m; and

24m at 8.6g/t silver from 24m.

RCBR0004:
2m at 1.2 per cent copper within 15m at 0.3 per cent copper from 37m.

RCBR0006:
2m at 2.7 per cent copper within 32m at 0.5 per cent copper and 0.5g/t gold from 28m; and

66m at 0.4g/t gold from surface to end of hole, including 1m at 1.2g/t gold and 1m at 1g/t gold.

RCBR0007:
1m at 1.3 per cent copper within 11m at 0.3 per cent copper from 32m;

18m at 0.4g/t gold from 27m, including 1m at 2.9g/t gold; and

16m at 4.9g/t silver from 26m, including 1m at 32.2g/t silver.

“These are very pleasing results,” Navarre Minerals managing director Geoff McDermott said in the company’s announcement to the Australian Securities Exchange.

“The high-grade secondary copper close to surface over an extensive area is strong evidence for primary porphyry copper mineralisation at depth.

“Broad intercepts of gold with base metal and silver are indicative of an epithermal target, which is commonly found in association with porphyry deposits.

“The tenor of grade intersected in our drilling, the widespread metal endowment and alteration patterns support our belief that we are dealing with a very large hydrothermal mineralising system at Eclipse.”

The results come from the first 7 holes of an 11 hole, RC drill program aimed at confirming a blanket of secondary copper (chalcocite) mineralisation, which Navarre said occurs above widespread copper, gold and zinc mineralisation, which it considers to be associated with a deeper porphyry target.

Assay results from the final batch of RC samples are expected later in March.

A number of other sample intervals from within the surface depleted zone have also been dispatched for gold assay, prompted by the wide distribution of high gold grades received in the initial results.

Investigator Resources eyes new IOCG targets on Yorke Peninsula

THE DRILL SERGEANT: Investigator Resources (ASX: IVR) has completed geophysical surveys in the ‘copper triangle’ on the Yorke Peninsula of South Australia, which the company says has upgraded the iron oxide copper gold (IOCG) potential of its 100 per cent-held Roundabout and Spyall prospects.

Investigator has combined an aeromagnetic survey with a recently completed gravity survey, the result of which it considers highlights shallow exploration targets between 50 metres to 200 metres depth approximately 40 kilometres northeast of the historic Moonta mines and about 100km north along a prospective trend extending from the 2008 Hillside copper discovery.

Peninsula. Source: Company announcement

 

The company said using the geophysical targeting techniques enables it to better pinpoint targets for cost-effective testing with shallow drilling.

“Geophysical techniques were critical to the successful discovery of IOCG deposits such as Olympic Dam and Carrapateena, which lie beneath deep cover in central South Australia,” Investigator Resources managing director John Anderson said in the company’s announcement to the Australian Securities Exchange.

“The surveys we have undertaken on Yorke Peninsula suggest shallow targets of IOCG character, which could be quickly and cost effectively tested with relatively short drillholes.

“What we like about our 1,000 square kilometres of tenements on the Yorke Peninsula is the under-explored nature of this area – there are very few holes below 50 metres – despite the region’s prolific copper history.

“Investigator is very much focused on advancing its silver, lead and copper targets around the Paris silver project and at Uno/Morgans on the Eyre Peninsula, but we are fortunate to have expanded our portfolio of quality exploration targets by extending our new targeting ideas onto Yorke Peninsula.”

Investigator’s intention is to drill the best targets at Roundabout and Spyall as early as possible in 2014, subject to access agreements in consultation with the local farming community given seasonal cropping activities.
