ALIEN CONFIRMS CONFIDENCE IN SILVER RESOURCE
AT ELIZABETH HILL SILVER PROJECT
Further to Alien Metals Limited’s (“Alien Metals” or “Company”) announcement, dated 4 December 2019, that it has entered into a conditional agreement (the “Agreement”) to acquire a 100 per cent interest in the former producing Elizabeth Hill Silver Project (“Elizabeth Hill Project” or the “Project”) from Karratha Metals Group Limited (“KMG”) in Western Australia (“the Agreement”), the technical team has reviewed provisional data supplied by KMG. Completion of the acquisition remains conditional on, amongst other matters, satisfactory mutual due diligence on the Project and Alien by the parties, required regulatory approvals and approval by KMG’s shareholders for the distribution (as detailed below). This announcement is available in PDF format from www.alienmetals.uk/assets/docs/nr/nr-2019-12-17-elizabeth-hill.pdf. Details of the provisional data are set out below.
Elizabeth Hill’s initial 1999 JORC Compliant Resource of 4.05 million ounce (“Moz”) silver at greater than 200 g/t silver: 46,800 tonnes grading 2,700 g/t silver (1.15 oz/t gold equivalent)(Ian Cowden, Iana Pty Ltd, Resource Estimate, Elizabeth Hill Silver Mine, November 1999)
1,170,000 ounces of silver mined between 1998 and 2000 at an average grade of 2,195 g/t silver (70.24 oz/t silver)
Unique mineralisation system which has produced Australia’s largest silver nugget weighing 180 kg (see Figure 1) and many other very large specimens of native silver
Silver resource also present in near surface material via standard open pit mining method above the existing underground workings
Independent reports suggest potential for further high grade material within the existing mine
Depth extension of high grade mineralisation below 100 metres (“m”) untested
Several surface robust geophysical anomalies untested within the Mining Licence
Alien to re-evaluate the 2011 mining scoping study on the Project
Detailed data compilation underway and a site visit ahead of outlining the first stage of exploration
Australia’s largest native silver nugget was found at the Elizabeth Hill Silver Mine in 2000, weighing 180 kg (~6,300 oz). See figure 1:
Further to Alien Metals Limited’s (“Alien Metals” or “Company”) announcement, dated 4 December 2019, that it has entered into a conditional agreement (the “Agreement”) to acquire a 100 per cent interest in the former producing Elizabeth Hill Silver Project (“Elizabeth Hill Project” or the “Project”) from Karratha Metals Group Limited (“KMG”) in Western Australia (“the Agreement”), the technical team has reviewed provisional data supplied by KMG, including historical sampling and test results, independent reports on the Project and extensive historic exploration data Completion of the acquisition is conditional on, amongst other matters, satisfactory mutual due diligence on the Project and Alien by the parties, required regulatory approvals and approval by KMG’s shareholders for the distribution (as detailed below).
A rare aspect of this deposit are the numerous silver nuggets that have been discovered to date which are highly sought after from collectors and in value terms command multiple times the actual silver content of each one due to their uniqueness.
At Elizabeth Hill, there appears to be significant unmined resources remaining based on the 1999 Resource estimation report and more recent exploration completed. Evaluating the potential of this resource will be a priority of the Company in order to determine an option to recommence a low cost mining operation considering this is an existing mining lease.
Bill Brodie Good, Technical Director of Alien, commented:
“From an initial review of the data supplied to Alien it is clear that there has been some excellent historic exploration and resource work completed which gives Alien a great platform to work from and develop. We are very keen to review and compile in detail all the available data plus any new data, for example satellite imagery, regional exploration etc. This will provide us with the information to execute a cost effective, but highly focussed, next stage exploration plan which will add significant geological and economic information to the Project, and therefore advancing it accordingly.”
Elizabeth Hill Silver Project Overview
The Elizabeth Hill Silver Project is situated approximately 45 km south of Karratha in the 61,000 km2 Achaean Pilbara Block of the Pilbara Craton. The Project is well located, lying 40 km from the deep-water port at Dampier and eight kilometres from rail infrastructure. Grid power and groundwater are available on site, and the area has an abundant skilled workforce nearby.
High-grade silver was discovered during nickel-copper exploration by AGIP in 1987. Further exploration of the project by ASX-listed East Coast Minerals (now KMG) and Legend Mining Ltd (ASX-LEG) discovered a very rich silver deposit. Mineralisation is related to shear structures to the Munni Munni Complex including the Munni Munni platinum/palladium deposit (formerly the Hunters PGE Reef, see Figure 2) lying immediately to the west. Native silver and lesser amounts of silver sulphide minerals occur as both fine and coarse grains within a coarse-grained calcite vein stockwork.

Previous Work on the Elizabeth Hill Project1
The Elizabeth Hill Silver Project was mined between 1998 and 2000 via underground mining, primarily between the 62 m and 102 m levels. Silver production totalled approximately 16,800 tonnes of ore grading 2,195 g/t silver (70.24 oz/t silver) generating 1,170,000 ounces, including some very large specimens of native silver.
The initial 1999 JORC Compliant Resource of the Project contained a total and an indicated and inferred Resource of 4.05 M oz silver, as set out in Table 1 below (at a cut-off grade of 200 g/t Ag). This Resource is based on an exceptionally high grades of 2,700 g/t silver (over 1 oz/t gold).

Alien will carry out a site visit and data compilation of historical information ahead of outlining an initial exploration programme on completion of this deal to ascertain the following phase of work needed to advance the project to the next stage as discussed above which could include updating the resource, testing new targets within the lease and conducting a scoping study to assess the viability of reopening the mine.

Notes to Editors
Alien Metals Ltd is a mining exploration and development company listed on AIM of the London Stock Exchange (LSE:UFO). The Company’s focus is on precious and base metal commodities.
Alien has embarked upon an acquisition-led strategy headed by a strong geological team to build a strong portfolio of diversified assets including two recent acquisitions in 2019. These include the Brockman and Hancock Ranges high grade (Direct Shipping Ore) iron ore projects and the Elizabeth Hill Silver projects both located in the Pilbara region, Western Australia.
In addition to progressing its acquisition-led strategy, and following its strategic review of its portfolio of silver and precious metals projects in Mexico, Alien has identified priority exploration targets within its 12 mining concessions which it is working to advance systematically. The Company’s silver projects are located in Zacatecas State, Mexico’s largest silver producing state which produced over 190m oz of silver in 2018 alone accounting for 45% of the total silver production of Mexico for that year.
The location of the Silver and Iron Ore projects which Alien Metals is in the process of acquiring, situated in Pilbara, Western Australia is shown in figure 3:

Resource - A mineral resource is a concentration or occurrence of solid material of economic interest in or on the Earth's crust in such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction.
Indicated - An ‘Indicated Mineral Resource’ is that part of a Mineral Resource for which quantity, grade (or quality), densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit.
Inferred - An ‘Inferred Mineral Resource’ is that part of a Mineral Resource for which quantity and grade (or quality) are estimated on the basis of limited geological evidence and sampling. Geological
evidence is sufficient to imply but not verify geological and grade (or quality) continuity. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.
