Alien Metals Limited, the AIM quoted mineral exploration and development company, is pleased to provide shareholders with an update following the recent site visit undertaken by its technical consultants as part of the due diligence on the Hancock Ranges and Brockman iron ore projects. The Company has an exclusive option to acquire 51% of these projects and the site visit has formed part of the due diligence by Alien (see the Company’s announcement dated 20 September 2019 for further information on these projects and the option).
- Independent laboratory analysis of 17 rock chip samples taken from both tenements has highlighted the high-grade direct shipping ore (DSO) potential
- Results suggest that both projects potentially host iron ore
mineralisation comparable to that being mined by the major operating
companies in the region. High-grade assay results include:
- Sirius Extension prospect: 64.2% Fe
- Kalgan prospect: 63.9% Fe
- BHP 20 prospect: 60.3% Fe
- BHP 19 prospect: 65.4% Fe
- The site visit confirmed the locations of the 2013/14 Volta Mining RC drill hole collars and the interpreted mineralised zones suggested to be within the Hancock Ranges project area
- The site visit also confirmed excellent potential of the Kalgan prospect in the Hancock Ranges project to host significant tonnages of DSO grade iron ore
- Initial geological mapping and sampling of the historic BHP 20 deposit on the periphery of the Brockman project indicates that the mineralisation extends onto the project tenement
- Option period mutually extended by 15 days, to 18 November 2019
Technical Director of Alien Metals, Bill Brodie Good, commented that “the initial assay results and geological information from the technical due diligence field trip are highly encouraging. Of the 17 samples taken across the two projects, numerous assays returned greater than 60%+ Fe, which is direct shipping ore quality, and the brief geological mapping carried out further enhanced the perceived potential of both projects. The assay results corroborate sampling and drilling undertaken by Volta Mining in 2014 at the Hancock Ranges project, and also the significant potential at the Brockman Iron project, where major iron ore companies are drilling on adjacent tenements.”
The location of the Brockman Iron and Hancock Ranges tenements are set out in figure 1:
Independent assay results
A total of 17 iron ore rock chip samples were taken in the course of the due diligence field work.These samples were initially analysed in the field by a portable X-ray fluorescence device (“PXRF”) followed by full analysis by Li Borate fusion/XRF analysis at the independent Intertek Genalysis laboratory, Perth, Western Australia.
A full table of the assay results is included below.
The geological due diligence carried out along with the supporting assay results confirm the presence of high-grade DSO material within all project targets, identifying areas for follow-up exploration.
Site visit summary
Brockman Iron Project (E47/3953)
The BHP20 Deposit appears to be many metres thick in slope exposure, a couple of hundred metres in width, and to dip gently 20 degrees to the north and to plunge gently towards 240 degrees. It therefore plunges NW across the body of E47/3953, beneath which it could potentially continue at accessible depths.
Photographs of the iron ore outcrop and sample sites for P592810 and P592812 “BHP20 deposit” at the Brockman Iron Project are set out in figures 2 and 3:
The locations of samples with assay results taken in October 2019 at the BHP20 prospect, Brockman Project, are set out in figure 4:
The BHP19 Deposit is located in the far SW corner of
E47/3953, and it dips and plunges to the NW, out of the lease, into the
adjoining Fortescue Mining Group (FMG) ground. FMG have an active grid
drilling programme on the adjacent ground, exploring the NW
continuation of the BHP19 Deposit and also what appears to be a
considerable deposit of derived detrital iron formation deposited on its
immediate southwest side.
The locations of samples with assay results taken in October 2019 at the BHP19 prospect, Brockman Project, are set out in figure 5:
Hancock Ranges Project (E47/3954)
At the Sirius Extension prospect, the drill collars from RC drilling undertaken by Volta Mining in 2014 were located during the site visit. One of these holes (Hole 14SERC004) returned 126m @ 60.28% Fe from surface.
From the site visit, additional parallel fold/fault-repeated outcrops
of similar iron formation just to the southwest of the historical
drilling were also noted. The observed mineralisation is part of the
larger Sirius deposit (124Mt at 60.3% Fe) on the adjoining Brockman
leases and there does appear to be potential for discovery of nearby
additional iron mineralisation within the Sirius Extension prospect.
The locations of samples with assay results taken in October 2019 at the Sirius Extension prospect, Hancock Ranges Project, are set out in figure 6:
From the ground traverse made during this initial site visit over the Kalgan
prospect the mineralisation appeared patchily exposed at surface, as
sub-crop and rubble, over a significant area, extending perhaps 500m
from SSE to NNW and 200m from E to W.Further to an initial
photo-geological study as part of the due diligence its expression
suggests that it may be controlled by a zone of NW-SE faulting that cuts
across the WNW-ESE stratigraphy.
The locations of samples with assay results taken in October 2019 at the Kalgan Prospect, Hancock Ranges Project, are set out in figure 7:
As announced by Alien on 20 September 2019, historic exploration has identified mineralisation at surface in the Kalgan prospect, with Volta Mining reporting eight rock chip samples which returned grades of up to 68.7% Fe in the prospect area. Assay results from Alien’s recent due diligence site visit confirm these high-grade results, with assay results for the three Kalgan samples returning grades up to 63.9% Fe.
The site visit and independent laboratory results has reaffirmed the Company’s views on the exploration potential of both of the Windfield projects. Following the receipt of the complete due diligence report, the Company will be in a position to make a decision on proceeding with the 51% project acquisition. In conjunction with the Company’s technical consultants, the Board will design a field program to follow up the most prospective DSO areas to get a better understanding of the potential extent of mineralisation.

Notes to Editors
Alien Metals Ltd is an AIM quoted mining exploration and development company. Since the recomposition of the Board and company name change in 2018, Alien has focused on delivering its strategy of acquiring mining projects which demonstrate significant development upside, in jurisdictions with established infrastructure and mining codes, and where strong operational controls can be assured.
In addition to progressing its acquisition-led strategy, following the strategic review of its portfolio of projects in Mexico during 2018-19, the Company has identified exploration targets across its 12 mining concessions in Zacatecas, Mexico, which it is working to advance systematically.
