                    Maiden Drilling targets identified at Hamersley Iron Ore Projects

 

Alien Metals Ltd (LSE AIM:UFO)  ("Alien Metals" or the "Company"), a minerals exploration and development company, is pleased to advise that further to the RNS dated 9th October 2020, the Company's technical team is able to report on the successfully completed detailed geological mapping and sampling programme at the Company's Hamersley Iron Ore Projects.

 

Highlights:

-      Detailed geological mapping and sampling completed over four of the five priority prospects

o  Field observations indicate that the BHP 19 and BHP 20 prospects may be part of same larger system

o  Additional prospective iron ore units mapped at the Brockman Iron project

-      Programme has been successful in validating previously announced Maiden Exploration Targets across both projects

-      95 samples were taken across the projects, with assay results expected late October 2020

o  Preliminary Handheld XRF results are consistent with those observed in the 2019 field programme, with reported ranges of 40-70% Fe

o  High-grade sample locations extend previously mapped prospective areas which are outside of those incorporated into the Company's maiden Exploration Target  

-      Final results from sample assays and detailed mapping to assist with preparation of maiden drilling campaign

-      Alien Metals has commenced preparing a Program of Works ("POW") for submission ahead of drilling  

 

Chief Executive Officer, Bill Brodie Good said: "The findings from the recently completed field programme are extremely pleasing and further validate the Company's exploration targets. The field work has expanded upon the previous site visit, with the validation of recent research and the potential increase in projected DSO mineralisation within both tenements. It should be noted that the field team advised how busy both areas were in terms of neighbouring companies working in the region which further encourages us to push on with both projects.

 

"The Company's technical team is compiling and finalising the geological mapping across the Hamersley projects which will give us valuable information ahead of maiden drilling programmes. With over 90 samples collected from only four prospects in a short field programme, we are very encouraged and look forward to some comparable analytical results of the XRF readings to complement the visible interpretations made by the team. We are already considering the follow up program to cover the fifth target not reached yet which in itself still has great potential."

 

 

The two projects are within the Hamersley Province of Western Australia, known as one of the premier iron ore producing regions of the world.  The Brockman Project (E47/3953) is located in the west Hamersley Province, 100 kilometres ("km") northwest of the Rio Tinto iron ore mining town of Tom Price, and 90km west of the Tom Price to Dampier mine railway. The Hancock Ranges Project (E47/3954) is located in the east Hamersley Province, 15km north of the BHP iron ore mining town of Newman, and 20km west of the Newman to Port Hedland mine railway.

 

In the Brockman Project area mapping was concentrated on the areas within the lease closest to the historic BHP 19 and 20 deposits to further understand and test the potential of these 2 prospects. Sampling concentrated on the Banded Iron Formations ("BIF") as this was considered to represent the primary iron potential of the tenement.  Whaleback Shale was also sampled in areas where iron banding was prominent and Canga (detrital ore) sampling was also done but to a limited extent. A total of 64 samples were collected between these 2 prospects over 4 days of detailed traverses and mapping.

 

In summary the main outcome of the work has delineated that the Dales Gorge Member of the Brockman Iron Formation is the prominent iron bearing unit found in this area with associated transported Canga units and constitutes the host for the high-grade iron ore. Detrital river derived iron bearing sediments ("CID")  were also identified and it is felt that both the Canga and CID units also host potential resource tons as well as the in-situ BIF units. Importantly, the main exploration work being carried out by Rio Tinto directly south of the tenement is on the Canga and CID units further to their development of the major Caliwingina project already in production to the south in the same units.

 

All samples generated have been despatched to Intertek Genalysis at Maddington, WA, to be analysed for their Basic Iron Ore Package Analysis with XRF finish, which includes elements Fe, Al, Ca, K, Mg, Mn, Na, P, S and Si.  This is the same as the analysis used in the 2019 due diligence site visit and it will maintain consistency and comparability between these analyses. Prior to sending the samples to the laboratory the Alien team tested then with a handheld XRF unit to get provisional grade readings to aid in the initial interpretation work. These readings are only a guide however from the similar analysis done in late 2019 the handheld XRF readings were within +/- 8% of the final laboratory results, so these represent an excellent first pass estimate of grades of the samples taken.

 

Table 1 below outlines the high grade XRF results from the Brockman Project BIF samples, with a maximum of 69.6% Fe.

Although BHP only reported 2 iron ore deposits, from this field work it appears that the intermittently exposed upper and lower iron bearing units within the Dales Gorge Member both present as prominent scarps that can be traced both within and beyond the bounds of the tenement. Hence the prospectivity of these 2 prospects extends well beyond the bounds of the historical deposits identified by BHP. The observed spatial coincidence of both the historic BHP deposits with prominent detrital iron occurrences would suggest that BHP was in fact targeting these detrital Canga deposits.

 

Significantly for Alien Metals the continuity of grade in relation to the mapped units of the primary units sampling show excellent correlation and significant continued very high-grade DSO level iron ore in significant volume. Figures 2 and 3 below show the XRF grade of sampling completed in relation to location of the sampling.

 

 

 

The 2 main prospects in the Hancock Ranges Iron Project were mapped as part of the programme. Helicopter support was utilised to transport the team directly into areas of the Kalgan prospect to maximise field time against travel time and over 40 further samples were taken with more detailed and positive mapping carried out.

 

All samples generated have been despatched to Intertek Genalysis. As with the samples from the Brockman project prior to sending the samples to the laboratory the Alien team tested then with a handheld XRF unit to get provisional grade readings to aid in the initial interpretation work. These readings are only a guide however from the similar analysis done in late 2019 the handheld XRF readings were within +/- 8% of the final laboratory results, so these represent an excellent first pass estimate of grades of the samples taken.

 

Table 2 below outlines the high grade XRF results from the Hancock Ranges Iron Project BIF samples, with a maximum of 70.07% Fe.

Seven mapping transects were walked across the Kalgan Prospect to test for the presence and lateral extent of previously reported high grade occurrences of iron ore.  In situ outcrop of rock was mapped with 128 mapping points and 25 rock chip samples were collected from BIF outcrops where iron was the dominant mineral present. BIF dominated by silica bands, dolerite, shale and rhyolite was not sampled. In addition to the walked transects, a helicopter survey of the surrounding terrain was conducted and a further 12 samples were collected.

 

The Kalgan prospect initial XRF results show excellent continuation and correlation along close to a 3km strike length with excellent initial XRF grades of DSO level.

 

A series of BIF ridges were mapped parallel to the regional trend and on strike and parallel to the Kalgan prospect and have returned in the initial XRF analysis constantly high-grade Iron with the majority from the sampling averaging over 60% Fe.

 

While the mapping and sampling has not comprehensively evaluated all the BIF occurrences within the tenement at least two targets have been highlighted for immediate follow up  work and the Company will be able to finalise such plans on receipt of the final laboratory assays.

 

The Company is extremely pleased with the outcome of this field programme and will be able to finalise recommendations for next stage work following receipt of the final results from the laboratory analysis.

 

The programme was carried out on budget, on time and with no health or safety incidents and has provided better than expected results and potential for both projects.

 

Alien Metals looks forward to reporting the full results and interpretations and associated next stage plans once received in the coming couple of weeks.
