First Deeper Drill Find at South Billiton, Marshall Lake Camp
- 0.94% copper, 1.03% zinc and 49 g/tonne silver over 15 metres
- 30 metre wide sulphide intersection approximately 80-100 metres deep
- Sixth discovery at Marshall, located 600 metres south of Main Billiton Zone
- Identified with deeper penetrating airborne VTEM geophysics
- Key tuffite chert marker intersected
East West Resource Corporation (TSX-V: EWR) and its 50% joint venture partner, Eyeconomy Holdings Plc. (UKPLUS: EYE) announce that a sixth a new sulphide zone has been discovered at the Marshall Lake camp. The new discovery on the eastern side of the camp, 4 kilometres from Gazooma, on the Marshall Lake mineralized tuff horizon was drilled from an airborne EM conductor which was located by a Dreamcatcher (VTEM) helicopter borne survey 600 metres south of the Main Billiton Zone.
The sulphide zone was intersected between 115-130 metres in hole MAR-07-11 at a vertical depth of 80-100 metres below surface, 600 metres south of the Main Billiton Zone. Previous airborne systems and ground surveys undertaken between 1961 and 1995 in this area were unable to identify targets beyond the 75 metre depth. The drill confirmation of this target at South Billiton indicates the potential for modern VTEM technology to identify deeper prospects.
The new South Billiton discovery suggests that a number of other (high value) deeper zones could occur giving the possibility that the Marshall Lake Camp may have multiple mineralized lenses typical of many VMS Copper-Zinc discoveries such as Thomson Bousquet and Sturgeon Lake (Mattabi).
This new zone consisted of bands of massive sulphides up to 0.3 metres wide within a highly chloritized felsic tuff, adjacent to a chert (silica) tuffite exhalite and disseminated sulphides. Chalcopyrite, pyrite and sphalerite occur in the hole, which are typical of the Main Billiton sulphides located 600 metres further north. Another showing occurs 300 metres further southeast of the new discovery and may be the up-plunge extension. Narrow zones up to 0.3m of remobilized chalcopyrite, pyrite and sphalerite occur in the fragmented units above the key tuffite marker. True thickness is estimated to be 80% of the core length, based on core angles on the contact of the zone.
This hole is the first intersection for East West and Eyeconomy that contained a wide extensive chlorite footwall alteration zone, typical of those found beneath Volcanogenic Massive Sulphide (VMS) deposits in other camps such as Mattagami. The cherty tuffite unit at 90-92m in the hole now gives a marker to follow to locate a larger zinc-rich zone. Small broken sections of cherty tuffite were observed in the Main Zone drill holes suggesting there is a link between the Main and South Zone.
Detailed follow-up geophysical surveys including resistivity soundings, IP and mise-a-la-masse are planned to trace the extent and direction of this new sulphide zone. It is becoming more apparent that a series of sulphide lenses could occur within the Marshall tuff horizon linked by a chert exhalite horizon, which is a similar setting found in the Noranda and Mattagami base metal camps in Quebec.
When analysing for basemetal and silver values (Copper, Zinc and Silver) were determined by ICP (inductively coupled plasma) after an aqua regia acid digestion. Assays exceeding 100 grams silver and 10,000 parts per million (ppm) copper were repeated using multi acid digestion and atomic absorption (AA). Check assays were run on high values. A standard sample is submitted for verification of accuracy. Gold values were determined by fire assay extraction on 30-gram samples followed by an AA finish.
ALS Chemex in Thunder Bay carried out preparations of the samples outlined in this news release and ALS Chemex in North Vancouver carried out assaying.
The project set out above is being supervised by R. Middleton, P.Eng, who is the qualified person and responsible for quality control of the assaying and reporting. Detailed assays for this drill hole are available on the company’s website.
