Muller Range (EL2356)

The PNG Fold Belt contains the Ok Tedi porphyry copper-gold Mine (located 80km WNW), Porgera intrusive/ epithermal related gold Mine (120km east) and Kili Teke porphyry copper-gold Deposit (50km east). The giant Grasberg porphyry copper-gold +skarns is in this same zone in West Papua.
Drilling is strongly warranted and exploration to capitalise on the increased US dollar gold and copper prices and leveraged Australian dollar - PNG Kina will include drilling the Tingi and Baia porphyry targets.
The EL has been reduced to 3 non-contiguous blocks with 56 sub-blocks covering 187Km2, Muller EL is located in the highly geologically Prospective Fold/Thrust Belt of PNG, along strike from the Ok Tedi Mine and Frontier's Bulago Project. The areas are relatively close to infrastructure such as the Hides Power Station and roads.
The primary targets are shallow buried porphyry copper- molybdenum- gold mineralisation, higher grade skarns and epithermal gold.
The EL contains (NW to SE):
Two known drill ready porphyry occurrences at Tingi and Baia (never drilled).
A possible high sulphidation/ intrusive related gold Prospect, with a possible buried porphyry copper-gold-molybdenum target at Cecilia River.
Copper in stream anomalies in the structural zone to/at the Mt Sisa volcanic centre.
The Tingi Intrusive Complex is exposed over a 4 sq.km area making it a significant sized porphyry intrusive complex. Tingi is strikingly similar in tectonic setting, size, geology and mineralisation to the Ok Tedi porphyry copper-gold deposit. The main difference is the level of erosion, with Tingi being less eroded than Ok Tedi and therefore almost totally preserved.
Mineralisation is described as structurally controlled porphyry copper -gold mineralisation, marginal lead -zinc skarn with associated copper –gold -silver anomalism and low sulphidation quartz-sulphide gold + copper style veins. Better copper-gold mineralisation generally occurs at the upper margins of porphyry intrusions and within the adjacent host rocks, particularly where breccias provide permeability for the migration of mineralising fluids.
Biotite hornfels cap some intrusions and contact breccias are recognised. The Bougainville (Panguna) copper -gold porphyry has breccias formed within a barely unroofed apophysis on the margin of a larger intrusion and as such, the breccias at Tingi represent excellent exploration targets.

Historic exploration results at Tingi include:
Strong gold in soil anomalies (including 90m of 2.14 g/t gold to a high of 6.09 g/t gold), plus strong lead-zinc ridge soil anomalies (including 390m of 0.17% lead + 0.33% zinc) on the northern half of the main target, reflecting stratabound base metal skarn mineralisation along the base of the Darai Limestone. The tropical setting may have leached copper from the surficial soils and rocks and provided low copper assay results.
A 250m x 200m soil–rock-chip anomaly (>300 ppm copper and >0.1 g/t gold) was delineated coincident with phyllic-altered diorite.
Gold assays from float rock include 30 g/t gold, 12 g/t gold and 4.9 g/t gold. 
Outcrop rock grab samples include 1.1g/t gold + 0.26% copper + 0.29% lead + 8.8% zinc),  3.72g/t gold + 1.55% zinc + 0.53 g/t lead.
Pyrite altered quartzite wall rocks had assays to 0.97 g/t gold + 58 g/t silver + 0.24% copper, that probably represents low sulphidation epithermal quartz-sulphide gold + copper mineralisation that formed marginal to the porphyry copper-gold intrusions.
Channel sampling along strike of Jerry’s skarn (6m thick x 30m long + an additional 50m in gossan outcrop to the southwest) returned an average for 20 non-continuous outcrop channel samples of 1.18g/t gold. A total of 15 x 2m channel samples were taken with best results of 2m continuous chip sampling showing 28m of 0.78 g/t gold including 2m of 4.36g/t gold and 2m of 2.58g/t gold.
10m of polymetallic massive sulphide assayed 3.3 g/t gold + 0.12% copper + 0.8% lead+ 1.9% zinc, within potassically and phyllicly altered diorite, representing a feeder for the base metal skarn mineralisation.
A 24m wide zone of copper averaged 0.085% copper within andesite porphyry, with up to 10% pyrite and minor chalcocite.
A 3m channel sample of brecciated massive sulphide magnetite skarn at the andesite porphyry / Darai Limestone contact assayed 1.17 g/t gold + 33 g/t silver + 0.16% copper + 1.80% lead + 3.50% zinc.

The Baia Project is a >4 sq km porphyry system, with the correct geochemical, geological and structural characteristics that strongly warrants exploratory drilling. 
Baia has a large copper - gold - molybdenum in soil anomaly and seven copper- molybdenum anomalous skarn targets that are defined by magnetic anomalies at the limestone /intrusive contact.
The project is located on the Porgera Mine - Mt Kare Transfer Structure which reputedly controls fracturing and mineralisation. It is about 50km south of Harmony’s excellent Kili Teke porphyry copper -gold discovery.
Copper in soil geochemistry demonstrates a distinct cohesive anomaly that is about 900m long north- south and about 600m wide east -west. There are three smaller, but still large, copper anomalies that are about 500m long and up to 200m wide, associated with skarns.
Zinc and lead soil geochemistry at Baia demonstrates a typical zinc/ lead halo around a 1,000m diameter core to the porphyry copper system, which is approximately coincident with the outer margins of the copper anomaly. The zinc/ lead anomaly has a width of about 500m and an outer annulus diameter of about 2,200m.



The Cecilia Prospect can be rapidly advanced to drill testing with additional exploration.

Dominant alteration is propylitic, with structurally controlled phyllic and patchy un-mineralised potassic.
Regional airborne magnetics show peripheral magnetic anomalies related to intrusives. The prospect is located on a topographic high in a major ENE trending fault zone/ transfer structure (as per the OK Tedi Mine located to the WNW).

 
Cecelia requires substantial exploration to evaluate its epithermal gold prospectivity.
The mineralised zone is about 2.5km long, initially being ENE gold-zinc-lead anomalism that transitions through an argillic alteration zone to copper molybdenum - arsenic anomalism (each being >1,000m long with argillic displaced to the south).
Cecilia has high sulphidation epithermal gold type advanced argillic alteration, with vuggy quartz - alunite- pyrophyllite, plus strong argillic and propylitic alteration, which has been covered by a recent agglomerate
Stream sediment geochemistry >250ppm copper and altered rock chip samples returned 0.616g/t gold and 0.12 g/t gold + 710ppm copper.
Intrusive outcrop up to 0.62% copper with chalcopyrite and bornite in the upper reaches of the Project area and altered granodiorite float of 0.18% copper.
Pebble dykes are common, indicating a probable buried porphyry copper-gold-molybdenum target.

Despite its seemingly remote location, potential access to a possible mine is relatively good, with several options available to the area. The biggest plus is that it is located near the Hides Power Station and immediately adjacent to Esso/Oil Search’s Juha Gas – Condensate field. When Juha is developed is of prime importance to a possible Tingi mine, in that a Topping Plant could be set up at Juha 3 to provide unlimited gas for a thermal power station, diesel fuel for mine operations, and possibly Jet A1 fuel for aircraft operations, plus better access.
