Zenith is very pleased to advise that initial field reconnaissance programs undertaken to assess the newly acquired Rio Tinto’s (ASX:RIO) Earaheedy tenements have been highly successful with the discovery of two new manganese prospects, Bluegrass and Blue Elbow (Figure 1).
A targeted geological reconnaissance mapping program to assess the area immediately along strike of Zenith’s Lockeridge Manganese Prospect identified generally north-dipping, outcropping manganese horizons over 3 kilometres of strike at Bluegrass and over 500 metres of strike at Blue Elbow. This reconnaissance program conducted over 2 days was focused on two areas identified in Zenith’s desktop manganese target study.
The Company is highly encouraged by this small focused first-pass program which delivered two new manganese prospects, and validates Zenith’s targeting methodology as well as vindicating the decision to acquire the Rio Tinto’s Earaheedy tenements which form a coherent land package covering the most manganese prospective portion of the western Earaheedy Basin. The Company believes that further systematic geological mapping programs over the newly acquired tenure are likely to turn up additional manganese prospects.

Bluegrass Prospect
A new strike extensive zone of manganese mineralisation was identified at Bluegrass along trend from Zenith’s Lockeridge Manganese Prospect where drilling in 2013 returned: 3 metres @ 25.1% Mn from 8 metres and 3 metres @ 20.2% Mn from 27 metres depth in a gently northeast dipping horizon. Manganese mineralisation at Bluegrass crops out over 3km of strike (east-west orientation). Massive manganese beds vary from 0.1 metres to greater than 1.5 metres thick, locally interbedded with thinner, folded, diffuse manganese zones 0.1 metres thick and quartz manganese rich zones that appear to be locally orthogonal to the overall strike of mineralisation (Figure 2). Locally it appears there is more than one massive manganese unit.
Rock chip sampling has been completed and analytical results are awaited.

Blue Elbow Prospect
The manganese mineralisation outcrops above a ferrigunous chert which forms a small east-west ridge at the newly discovered Blue Elbow Prospect. Manganese mineralisation is in-turn overlain by hematitic shales that form a topographic dip surface (shallow northerly dip ~5 degrees), it is likely that the manganese horizon extends to the north at shallow depths beneath this hematitic shale unit (as shown below). This rock sequence is a similar stratigraphic succession to that at Zenith’s Red Lake Manganese Deposit where drilling by Zenith in 2012 returned results up to: 3m @ 41% Mn (within 5m @ 34.8% Mn from 22m depth), and 3 metres @ 34.8% Mn from 19 metres (ZLRC057), including 1m @ 42.3% Mn. Along strike to the east the manganese was tracked in 3 horizons, 2 that parallel the chert ridge the other which strikes more north-south into a small topographic saddle – the latter zone is both massive but generally patchier with more rock clasts in the manganese zone than observed in the main ridge zone area (Figure 3).

BACKGROUND
Zenith was the first mover for manganese in the Proterozoic aged Earaheedy Basin in Western Australia, and has discovered and drill tested several zones of near surface manganese oxide. In 2012 the Company reported the first potential direct shipping ore (“DSO”) grade manganese drill intersections in the Earaheedy Basin and in April 2013 completed a maiden JORC Inferred Resource at the Red Lake deposit, as well as preliminary metallurgical work.
The Proterozoic aged Earaheedy Basin north of Wiluna in WA is a potential new manganese province with similarities to the giant Kalahari manganese field in South Africa. As first mover Zenith established a strong land position with tenements covering ~75 strike km of prospective stratigraphy, subsequently extended to ~130km with the recently acquisition of Rio Tinto’s Earaheedy tenements. Zenith’s priority target is high-grade (>40% Mn) manganese oxide formed by weathering or supergene upgrade of primary carbonate manganese.
Zenith completed the first ever drilling for manganese in the western Earaheedy in late 2010 at the Lockeridge prospect, intersecting a shallow dipping bed of manganese mineralisation extending from surface to 1.2km down dip. Better results from Lockeridge include 12m @ 11.1% Mn from 28m depth, and 3m @ 18.0% Mn from 37m depth. Subsequent drilling returned thick zones of manganese oxide at the Black and Blue prospect; 31m @ 7.9% Mn from surface, incl. 2m @ 17.1 %Mn, 1m @ 22% & 3m @ 14.3 %Mn.
The first DSO grade Mn drill intersections recorded in the Earaheedy Basin were reported by Zenith in 2012 at the Red Lake prospect. Drilling results include; 3m @ 41% Mn (within 5m @ 34.8% Mn from 22m depth), and 3 metres @ 34.8% Mn from 19 metres (ZLRC057), including 1m @ 42.3% Mn.
A maiden resource estimate for the Red Lake prospect was reported to the ASX on 9 April 2013. The tonnage/grade estimates are tabulated below at both a 5% and a 10% Mn cut-off grade. The resource estimate encompasses a faultbounded sub-horizontal manganese oxide horizon with a lateral extent of ~400 metres by 300 metres, up to 4 metres in true thickness.

Zenith’s priority target in the Earaheedy Basin is high-grade near surface direct shipping (DSO) manganese. In addition to the high-grade DSO manganese intersected in Zenith drilling to date, screening and metallurgical testwork by Zenith shows potential to significantly upgrade the lower grade manganese horizons and further testwork is planned on coarser sample sizes that will better represent manganese material that may be mined.
The Earaheedy project also includes a 30 km long zone of carbonate-hosted zinc (Zn) and lead (Pb) mineralisation in the Yelma Formation at the base of the Earaheedy Basin stratigraphy. Broadly spaced drilling by RGC Exploration from 1992 to 1996 defined several prospects containing drill intersections of oxidised and primary Zn-Pb mineralisation, including;
-
Navajoh: 7.3 m @ 6.1 % Zn, 0.77% Pb (incl. 3.3 m @ 11.2% Zn, and 0.93% Pb)
-
Magazine: 5 m @ 5.6% Zn +Pb (incl. 2 m @ 8.2% Zn, 2.8% Pb)
-
Chinook: 6 metres @ 3.63% Pb +Zn.

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 down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad _meaning of sampling. _ |
Samples were collected by hand, at the surface, from in-situ outcrops. These samples are believed to be representative of the global outcrop. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
Grab samples are believed to be representative of the outcrops they come from. |
|
| 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. |
1-2kg rock samples were collected by a geologist, samples were generally broken using a hammer from outcropping Mn mineralisation. Rock samples were crushed in the laboratory and then pulverised before analysis. |

Surface sampling and mapping were completed over different field campaigns by Zenith Minerals. Manganese oxide outcrops were the starting point to drilling at Red Lake. A regional aeromagnetic survey was completed in 2007. Faults surrounding the Red Lake Prospect were interpreted from this survey. Basic dry screening sighter tests were completed at Red Lake and suggest a good potential for upgrading of Mn mineralisation.
