ASX Announcement (ASX: AXE )
22 August 2017
Cobalt footprint expanded at North Broken Hill
Highlights
-
Nine cobalt prospects identified at EL 8954 across an area covering 9km[2] , including the Yancowinna and newly discovered Golden King West prospect.
-
Less than 25% of the North Broken Hill project area has been sampled to date.
-
New rock chips of up to 0.15% (1,500ppm) cobalt and up to 15.45% copper recorded, supporting previously reported levels of up to 0.30% (3,000ppm) cobalt and 0.65% copper.
-
Yancowinna Prospect strike length extended from 500m to 2.5km.
-
EL 8594 is underexplored with no historical drilling recorded within the tenement area.
-
The ongoing regional sampling program is continuing to be effective in ranking the growing cobalt anomalies within the larger North Broken Hill Project area, with results from the reconnaissance exploration to be reported as they are received and interpreted.
Archer Exploration Limited (ASX:AXE, Archer or the Company) is pleased to update the market with results from the Company’s ongoing reconnaissance rock chip sampling program undertaken across regional prospects on the Company’s 100% owned North Broken Project, located approximately 20km north of Broken Hill, NSW. The entire project area remains highly prospective with less than 25% of the total project area being sampled to date.
Reconnaissance sampling has been focussed primarily on tenements EL 8592, 8593 and 8594 (Figure 1), where approximately 60% of previously recorded cobalt targets in these areas have been visited and sampled. As a result of this early work, at EL 8594 Archer has successfully identified nine separate cobalt prospects within a larger mineralised envelope covering 9km[2] .
Tenement EL 8594 hosts the Yancowinna Cobalt Prospect and the newly discovered Golden King West Cobalt Prospect. Latest rock chip exploration results at Yancowinna and Golden King West, include:
-
0.15% cobalt and 0.64% copper at Golden King West (sample WD02793).
-
0.13% cobalt and 1.11% copper (sample WD02784) and 0.01% cobalt and 15.45% copper (sample WD02800) at Yancowinna.

These recent high-quality rock chip results support the prospectivity of EL 8594 where Archer has previously announced up to 0.30% cobalt and 0.65% copper in rock chips at Yancowinna (ASX announcement 28/07/17).
Greg English, Executive Chairman said “These latest results support the previous exploration results and confirm that Archer has discovered a significant zone of cobalt mineralisation at Yancowinna. The discovery of high grade copper associated with cobalt provides additional significant potential.”
“Golden King West is a new discovery for the Company with no previous cobalt mineralisation reported within this project area. We are excited by the prospectivity of EL 8594 as this tenement is underexplored, with no historical drilling recorded within the tenement area” said Mr English.
The Company’s larger reconnaissance exploration over the North Broken Hill Project area will continue during the next 4 – 6 weeks with the initial exploration efforts focussing on EL 8595, 8596, 8597 and 8598. All results from the reconnaissance exploration program will be combined with the existing geophysical data to allow the Company to rank prospects for further advanced exploration.

Project description
The North Broken Hill Project area is made up of seven granted tenements which are located in close proximity to Broken Hill. The underlying geology comprises the Thackaringa Group rocks (including the Himalaya formation) as well as other rocks of the Willyama Supergroup, including those that host the Broken Hill deposit. The Thackaringa Cobalt Project is located 30km to the southwest of the Project area.
Many occurrences of Broken Hill style (Pb-Zn-Ag) and copper mineralisation occur within the tenements, samples are being taken where considered relevant, but are not the focus of exploration.
Reconnaissance Sampling Program
This initial exploration work is continuing to target those areas that have been identified by NSW government mapping as hosting rock types that are prospective for cobalt mineralisation (e.g. Big Hill, Sisters and Great Eastern type).
To date less than 25% of the Project area has been sampled. The remaining sites will be visited over the coming weeks and months to further to assess their cobalt prospectivity and locations with cobalt potential will then be ranked and re-visited.
Results
The reconnaissance rock chip sampling program has so far identified nine distinct cobalt anomalies within the area of EL 8594 (including Yancowinna and Golden King West). The Company has also identified cobalt targets within the Himalaya Prospect (EL8593) where Archer has previously announced results of up to 0.16% cobalt in rock ships (refer to ASX announcement 28/07/17). All of these anomalies are new discoveries with no information available from historical datasets.
The rock chip results from the latest exploration work are described in detail in Annexure A.
Yancowinna Cobalt Prospect
The Yancowinna Prospect (including Acacia Tank and Yancowinna West prospects) is situated in the southern portion of EL 8594 (Figure 2). On 28/07/17 Archer announced the discovery of Yancowinna over an initial strike length of 500 metres. These latest results have significantly extended the Yancowinna strike length from 500 metres to 2.5km in length with the overall area of mineralisation extended to 9km[2] .
The Yancowinna Prospect is now described as largely covering EL 8594 (Figure 2) with cobalt values above 0.05% cobalt (500ppm) regularly reported within the larger zone of mineralisation.
The Yancowinna Cobalt Prospect, corresponds with previous NSW state government mapping, as occurring within a package of the Himalaya Formation which are the same rocks that host the Thackaringa Cobalt Project.

Golden King West Prospect
Tenement EL 8594 is divided into two distinct areas (Figure 2), the northern block which hosts the Yancowinna Cobalt Prospect and the southern block which hosts the Golden King West Prospect. The Golden King West Prospect is a new discovery by Archer.
At Golden King West, cobalt and copper mineralisation has been identified by Archer. The mineralisation appears to be hosted within a large structure (+300m) that cross cuts the local geology. Big Hill cobalt targets (same mineralisation as Cobalt Blue’s Thackaringa Cobalt project) identified by the NSW government to the west of Golden King West have not yet been sampled but will be targeted in future exploration programs.

Next Steps
The ongoing North Broken Hill Project regional rock chip sampling program is showing to be effective in discovering new cobalt and other anomalies within the larger Project area. These anomalies have mostly been discovered in areas where there has been no previous drilling for cobalt and associated mineralisation.
Archer will continue the regional rock chip sampling across the rest of the Project area and report these results as they come to hand. The data from the rock chip sampling will be integrated with geophysical data to prioritise and rank targets for future drill testing.

JORC Code, 2012 Edition – Table 1
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | JORC Code Explanation | Commentary |
|---|---|---|
| Sampling Techniques |
• Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as downhole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. |
• Random rock chip samples, some with obvious copper/base metal mineralisation. • Sampling was guided by Archer’s protocols as the program was exploratory in nature. No standards were submitted by the company during analyses. • All samples were sent to ALS laboratory in Adelaide for preparation and forwarded to Peth for multi-element analyses. • All samples are crushed using LM2 mill to –4 mm and pulverised to nominal 80% passing –75 µm. |
| Drilling Techniques |
• Drill type (e.g. core, reverse circulation, open hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc.). |
