On 29[th] September 2014 Zenith announced 4 high-priority resource extension targets at its Develin Creek Copper-Zinc-Gold-Silver Project, located in Queensland (51% owned, right to acquire 100% from ASX:FRY). The Company is pleased to advise that a 10 – 15 hole RC drilling program is now planned to start in late September to test these targets in conjunction with the systematic field assessment of the many high-priority regional prospects.

In addition an upgrade of the current JORC 2012 resource is in progress incorporating more recent drilling data including intersections of 13.2 metres @ 3.3% copper, 4.0% zinc and 0.4g/t gold outside the existing Sulphide City resource, extending mineralisation up to a further 200m south.

Key assets at Develin Creek include:
-
3 Massive Sulphide Deposits (Sulphide City, Scorpion and Window) with JORC 2012 Compliant Resources of 1.76Mt grading 1.7% copper, 2% zinc and 0.2g/t gold, total inferred resource,
-
Numerous other geophysical and geochemical targets along 50km of host volcanic rocks, with strong evidence that downhole electromagnetic (EM) surveys clearly detect massive sulphide zones, and induced polarisation (IP) geophysical surveys can outline the stringer zone mineralisation beneath the massive sulphides.
The Develin Creek base metals project is located 80km north‐west of Rockhampton in Central Queensland and hosts several copper-zinc-gold volcanic hosted massive sulphide (VHMS) deposits and covers an extensive belt of underexplored prospective volcanic stratigraphy. Mineralisation comprises massive sulphide, stringer and breccia style copper-zinc-gold deposits, hosted by basalts.
DEVELIN CREEK RESOURCE EXTENSION TARGETS
Significant potential exists to extend the currently defined copper-zinc-gold deposits and to discover new mineralisation lenses in higher or lower stratigraphic positions. A reverse circulation drilling program to test these targets is now scheduled to start in late September (Figure 1).

Key targets identified by Zenith include extensions to the massive sulphide horizons at Sulphide City. Data review and modelling by Zenith has led to the recognition of an interpreted new east-west trending fault that displaces mineralisation at the north end of the Sulphide City deposit. The deposit appears open beyond this fault, particularly extending down-dip to the northwest where existing drilling is sparse.
The main Sulphide City lens, outlined with a 1% copper equivalent cut‐off, has a horizontal projection of about 300m x 150m and varies from 2.5m to 29m in thickness. Better historic drill intersections (previously reported by Fitzroy Resources Limited to the ASX, 14[th] Oct 2010, 11[th] May 2011 and 28[th] Oct 2011) include:
-
FRWD0002 13.2m @ 3.3%Cu, 4.0% Zn, 30g/t Ag and 0.5g/t Au
-
DDH-016 14.5m @ 0.6% Cu and 4.3% Zn (includes 2.5m @ 12.0% Zn) DDH-044 11.3m @ 2.1% Cu, 5.9% Zn, 16g/t Ag and 1.21g/t Au

The north-easterly, down-plunge extensions to the main massive sulphide lens at the Scorpion Deposit (Figure 2 & 3) are open-ended beyond historic hole PD246 which intersected 12m @ 1.47% Cu, 1.33% Zn, 0.35g/t gold, and 10.3g/t Ag including 9 metres of logged massive sulphide, and require drill testing. In addition the northern down-dip extents of the Scorpion Deposit remain open. Sparse deeper drilling intersected bedded sulphides in holes DDH042 – 1.3m @ 1.0% Cu and 0.4g/t gold and hole DDH038 – 1.6m @ 1.5% Cu, 0.8% Zn and 0.3 g/t gold (Figures 2). This distal bedded sulphide target extends over an area some 200m x 350m and may extend as far as the Sulphide City deposit a further 400m northeast of the intersection in hole DDH042.
The Scorpion deposit, 500m south-west of the Sulphide City deposit occurs in a 400m X 200m zone in altered volcanic rocks, the sulphide body, 2.5m – 9.5m thick consists of brecciated massive sulphides grades up to 6% Cu, 9% Zn, 43g/t Ag and 1g/t Au. Better historic drill results (previously reported by Fitzroy Resources Limited to the ASX, 14[th] Oct 2010 and 11[th] May2011) include:
-
DDH-001 21.6m @ 2.5% Cu, 1.5% Zn, 13g/t Ag, 0.5g/t Au, (includes 16.2m @ 3.2% Cu, 1.6% Zn)

The area along strike and down dip of the Window deposit is also poorly tested and remains open (Figure 2). The highly weathered Window mineralisation consists of a supergene zone of secondary copper minerals within a steeply dipping stringer style mineralisation comprising a multiphase quartz / pyrite /chalcopyrite stockwork. The location and style of mineralisation indicates that Window may be the partially eroded footwall stringer zone to the nearby Scorpion massive sulphide lenses. Better historic drilling results previously reported by Fitzroy Resources Limited to the ASX, 14th Oct 2010) include PD-012, 84.0m @ 0.8% Cu (including 48.0m @ 1.2%).
Potential also exists for near deposit discoveries such as mineralisation concealed under extensive cover, particularly to the west where existing IP geophysical coverage terminates approximately 300m to the west of the Window-Scorpion deposit. It is also important to note that the detailed IP survey also terminates to the immediate east of the Sulphide City resource area, where there is a 250m x 900m gap in IP coverage before a widely spaced, more regional survey starts.
DEVELIN CREEK RESOURCES
The current (JORC 2012) Inferred Resource estimate was first calculated by Icon Resources to the ASX in 2007 for the three main mineralized bodies (Sulphide City, Scorpion and Window). Zenith completed a review and updated the resource to be compliant with the JORC 2012 guidelines in July 2014. The resource defined to date by drilling is: 1.76Mt grading 1.7% copper (Cu), 2% zinc (Zn) and 0.2g/t gold (refer to JORC compliant resource statement and associated tables attached to the Zenith June 2014 Quarterly Report, dated 30[th] July 2014).
| Deposit | Tonnes | Cu% Grade | Zn% Grade | Ag g/t Grade | Au g/t Grade |
|---|---|---|---|---|---|
| SULPHIDE CITY | 1,114,784 | 1.64 | 2.41 | 7.2 | 0.20 |
| SCORPION | 485,100 | 1.98 | 1.87 | 13.9 | 0.39 |
| WINDOW | 156,960 | 1.45 | - | 1.0 | 0.02 |
| TOTAL | 1,756,844 | 1.71 | 2.05 | 8.5 | 0.24 |
Subsequent to the resource estimates reported in 2007, drilling by Fitzroy extended mineralisation at the Sulphide City deposit by 200m to the south. Drilling intersections previously reported by Fitzroy (ASX Releases 28th July 2011, 28[th] Oct
2011 and 30[th] Jan 2012) that extend high-grade copper-zinc mineralisation to the north and south that are not included in the 2007 resource estimate above include:
-
FRWD0002 - 13.2m @ 3.3% Cu, 4.0% Zn & 0.4g/t gold (40m south of resource)
-
FRWD0004 - 1.1m @ 3.5% Cu, 1.7% Zn & 0.6g/t gold (140m south of resource)
-
FRWD0001 - 0.7m @ 4.7% Cu, 1.9% Zn & 0.8g/t gold (50m north of resource)
-
FRWC007 - 2.0m @ 0.2% Cu, 2.4% Zn & 2.2g/t silver (200m south of resource)
Zenith has commissioned an updated JORC resource that will include these additional drill holes.
BACKGROUND ON VHMS COPPER-ZINC-GOLD DEPOSITS
VHMS ore deposits are a type of metal sulphide ore deposit created by volcanic-associated hydrothermal events in submarine environments. VHMS deposits are a major economic source of metals worldwide and in particular contain large accumulations of copper and zinc with associated gold and silver that are exploited by both open pit and underground mining methods, the deposits occur in clusters and have well defined exploration vectors.
A study in 1980 on 8 VHMS districts in Canada and Japan (D F Sangster - Geological Survey of Canada) demonstrated that: on average the VHMS districts studied contained between 4 and 20 deposits, each district has an average of 12 deposits and the total base metal content of each district is 5.4 million tonnes.
The ongoing successful discovery of VHMS copper-zinc deposits in a single district is highlighted by the discovery history of the Bathurst VHMS district in Canada, where a total of 41 individual deposits have been discovered progressively over a 42 year period. The VHMS clustering is also well demonstrated via the discovery of deposits by Independence Group (and its predecessors) along the 15km long Bentley-Jaguar-Teutonic Bore mine trend, as shown below in Figure 4. Such deposit clustering is very likely at the Develin Creek project and it is anticipated that further exploration will result in the discovery of additional mineralisation.
