THE DRILL SERGEANT: Investigator Resources (ASX: IVR) received drilling and assay results for diamond and RCP drilling carried out at the Nankivel porphyry prospect, southeast of the company’s Paris silver project in South Australia.

Investigator Resources completed four inclined diamond holes, then 20 largely inclined RCP holes.

The diamond drilling intersected strong argillic, phyllic and pyritic alteration the company deemed to warrant immediate follow-up with RCP drilling to map the lateral extensions based on a preliminary target model.

The company said that analysis of both the diamond and RCP drilling assisted with petrology and multi-element pathfinder geochemistry under consultant advice, had modified the target model from the previously interpreted preliminary high-level epithermal setting, to a shallow undrilled porphyry target extending from the advanced argillic breccia outcrop on Nankivel Hill about 2km to the southwest.

Investigator said the upgraded potential warrants renegotiation of current heritage restrictions to the revised target area.

“Our porphyry copper target interpretation has been logically modified and upgraded by the recent drilling and the application of state-of-the-art models and exploration science, including pathfinder geochemistry,” Investigator Resources managing director John Anderson said in the company’s announcement to the Australian Securities Exchange.

“The alteration haloes and geochemical signatures around porphyry copper deposits are being increasingly understood, and we now have high-integrity evidence that suggests we are within drilling reach of a potentially large porphyry copper system immediately southwest of Nankivel Hill at a depth shallower than previously projected.

“This location is currently not accessible for drilling, so our immediate priority is to review the heritage boundaries with the Native Title Holders, with whom we have worked for many years and enjoy a good relationship.

“The bulk of the revised Nankivel target is under subdued topography compared with the adjacent hill.”

Investigator considers itself to be a pioneer in identifying the potential for porphyry mineral systems on the southern Gawler Craton, and declared it will continue to apply rigorous industry-leading exploration science typically the cutting edge applied by major companies.

“This approach minimises the usual exploration risk and provides the best discovery opportunities for our shareholders,” Anderson continued.

“As Investigator continues to drill and undertake collaborative research with the State Geological Survey and universities, several lines of evidence point to a transitional relationship between the IOCG deposits of the Olympic Dam belt and the emerging porphyry systems of which Nankivel is a prime example.

“This expands the copper potential in the southern Gawler Craton where Investigator has taken a strong tenement position.”

THE DRILL SERGEANT: Gold Road Resources (ASX: GOR) released an updated Mineral Resource for the Alaric Open Pit, located within the Gruyere Joint Venture tenements in Western Australia.

Gold Road Resources announced the 2012 JORC Code-compliant Mineral Resource for the Alaric deposit now totals 1.92 million tonnes at 1.51 grams per tonne gold for 93,500 ounces of gold.

This represents an addition of 47,200 ounces (+102%) compared to the Alaric Mineral Resource released in 2015.

Gold Road declared that 72 per cent of the 2017 Mineral Resource is classified in the Indicated category.

This has come about with material previously classified as Measured in the 2015 Mineral Resource being re‐assigned to Indicated based on the company’s understanding of appropriate drill spacing for the style of mineralisation and the observed variability of mineralisation at short range in the drilling data.

Gold Road said the 2017 Mineral Resource includes new information derived from the 2016 and 2017 diamond and Reverse Circulation (RC) drilling programs, which contributed to the update of the geological interpretation and grade estimation.

Other factors used in reporting the 2017 Mineral Resource include a lower cut‐off grade consistent with mining cost estimates derived from the Gruyere Feasibility Study and an increase in the gold price to reflect the changes in gold price since the 2015 Mineral Resource was declared.

“The increased Alaric Mineral Resource represents another step forward in our understanding and delineation of the deposits along the 14-kilometre mineralised Attila‐Alaric Trend,” Gold Road Resources executive director ‐ exploration & growth Justin Osborne said in the company’s announcement to the Australian Securities Exchange.

“Since we announced the Gruyere JV in late 2016 we have increased the combined Mineral Resource of Attila and Alaric by 150,400 ounces.

“Building on our knowledge gained from rigorous interrogation of the Alaric and Attila deposits we can now apply this improved understanding to our exploration program to build additional resources along the entirety of this prospective and well‐endowed trend.

“This includes extending our exploration efforts and methods along this system onto our 100 per cent tenement holding on the North Yamarna project, where we believe the same lithologies and structures extend all the way to our Pacific Dunes‐Corkwood Camp target over 50 kilometres to the north.”

THE DRILL SERGEANT: St George Mining (ASX: SGQ) received encouraging results from recently-completed regional EM surveys at the company’s Mt Alexander project in Western Australia.

St George Mining carried out the MLEM survey over a east-northeast corridor parallel to and one kilometre south of the Cathedrals Belt.

The survey identified a strong EM anomaly – Anomaly 11 –450m south of the intersection of this corridor with the northern extension of the Mt Alexander greenstone belt.

St George explained that this east-northeast feature was first recognised in high resolution magnetic data generated by an airborne magnetic survey it previously completed at Mt Alexander, adding that it may represent a primary transform fault that could host mineralised komatiitic ultramafics, similar to the Cathedrals Belt.

The MLEM survey modelled the EM plate for Anomaly 11 with dimensions of 113m by 91m and at a depth of 98m below surface.

The company has prioritised drill testing of this target for the next drill program at Mt Alexander.

The new high resolution magnetic data also identified the location of the Ida Fault within the Mt Alexander tenements.

St George believes the intersection of the Cathedrals Belt and Ida Fault could be an important geological location that could have acted as a first order regional control on mineralisation within the Mt Alexander tenements.

To confirm this theory, St George will carry out a high powered SAMSON EM survey over the western extension of the Cathedrals Belt including the area where these structures intersect, to search for any deep conductors that may represent massive sulphide accumulations.

“Geophysics has been an excellent exploration tool at Mt Alexander with EM surveys identifying numerous conductors in the Cathedrals Belt that have been drilled and confirmed as nickel-copper sulphide mineralisation,” St George Mining executive chairman John Prineas said in the company’s announcement to the Australian Securities Exchange.

“We are continuing to use reconnaissance geophysics in unexplored areas of the Mt Alexander project, and early results are encouraging.

“It is pleasing to see that as we advance prospects in the Cathedrals Belt, we also have very attractive exploration targets within the broader project area.”

THE DRILL SERGEANT: Impact Minerals (ASX: IPT) announced the thickest and highest grade gold intercept returned to date from the company’s 100 per cent-owned Commonwealth project, located near Orange in New South Wales.

Impact Minerals said the intercept was achieved in the first follow up drill hole to be drilled at the emerging high-grade gold-silver discovery at Silica Hill.

Hole CMIPT56, a reverse circulation (RC) drill hole, returned an intercept of:

14 metres at 4.5 g rams per tonne gold from 153m down hole, including 3m at 10.5g/t gold from 160m down hole.

Impact Minerals said the 14m intercept lies within a 40m thick intercept with greater than 0.1g/t gold.

The company made note that only the assays for gold have been received for this intercept, adding that gold assays for the remainder of the hole together with silver and other metals are expected within three weeks.

“This excellent intercept further demonstrates the potential for Silica Hill to deliver a significant discovery and we can draw three significant conclusions from it,” Impact Minerals managing director Dr Mike Jones said in the company’s announcement to the Australian Securities Exchange.

“First, as we have suspected, there are likely to be zones of much higher-grade gold in the system to accompany the exceptional silver grades of up to 3,100 grams per tonne already discovered.

“Secondly, we are seeing significant improvements in grade with closer spaced drilling and this offers the opportunity to rapidly increase the ounces of contained gold and silver within the area already discovered.

“Thirdly, the mineralisation is now open to the north west.

“These are all very encouraging developments.”

THE DRILL SERGEANT: Rox Resources (ASX: RXL) declared continued positive progress following a recently-completed diamond drill program at the company’s Fisher East project in the North Eastern Goldfields region of Western Australia.

Rox Resources said the drilling program tested deeper targets at the Sabre prospect and the Camelwood and Musket deposits.

Four of the five drill holes were also surveyed by Downhole EM (DHEM).

Rox reported the results from hole MFED076 at Camelwood show high-grade nickel sulphide mineralisation continues at least 100 metres deeper than previous drilling had indicated.

In addition, the DHEM results showed the possibility of mineralisation extending down dip to the south.

The drill hole was partially funded under the WA Government Exploration Incentive Scheme (EIS).

Assay results from hole MFED076 include:

7.7 metres at 1.4 per cent nickel from 693.3m, within semi-massive and disseminated sulphides, including 1.4m at 2.9 per cent nickel from 693.3m.

The drill hole at Musket intersected a brecciated and faulted zone where an intrusive porphyry may have disrupted the mineralised zone.

There is a strong off hole DHEM conductor, which Rox said could indicate a new mineralised zone and warrants drill testing.

Assay results from MFED079 include:

0.13m at 2.3 per cent nickel from 519.0m, within a nickel sulphide stringer;

0.5m at 4.7 per cent nickel from 522.5m, within matrix sulphides;

0.1m at 2.6 per cent nickel from 606.1m, within a nickel sulphide stringer; and

0.2m at 2.6 per cent nickel from 607.1m, within a nickel sulphide stringer.

Drilling at Sabre was designed to test the deeper portions of a conductive EM plate defined from ground surveys below previous RC drill intercepts.

The drill holes interested a mineralised zone of variable thickness, containing semi-massive and disseminated nickel sulphides.

Small, but strong DHEM conductors were detected adjacent to holes MFED075 and 077.

Assay results were:

MFED075
2m at 1 per cent nickel from 315.5m, within semi-massive and disseminated sulphides;

MFED077
4.8m at 1.2 per cent nickel from 330m, within semi-massive and disseminated sulphides; and

MFED078
2.3m at 2.4 per cent nickel from 337.3m, within semi-massive and disseminated sulphides, including 0.7m at 3.7 per cent nickel from 338.2m.

“The deeper diamond drilling has indicated that the Camelwood, Musket and Sabre mineralised zones do continue at depth,” Rox Resources managing director Ian Mulholland said in the company’s announcement to the Australian Securities Exchange.

“There are strong off hole EM conductors at all deposits that are worth following up.

“Our Mineral Resources at Fisher East are 2.04 million tonnes at 2.5 per cent nickel (at a 1.5% nickel cut-off) for 50,600 tonnes of contained nickel…and we are confident of adding to these resources as we continue to explore and test new targets and drill deeper holes at known deposits.”
