Main Billiton Zone Zinc Phase Intersected at Marshall Lake Property
- 9.2 metres of 2.02% Zinc, 0.45% Copper, 85 grams/tonne Silver, and 3.48 grams/tonne Gold
- High grade Gold assay of 28.70 grams per tonne over 1.0 metres
- Further validation of historic drilling on Billiton "Main Zone"
East West Resource Corporation (TSX-V: EWR) and Eyeconomy Holdings PLC (UK-PLUS: EYE) announce that the eastern portion of the Main Billiton VMS (volcanogenic massive sulphide) zone was intersected by hole MAR-06-09 (-45 degrees) which yielded a 9.2 metre section of 2.02% Zinc, 0.45% Copper, 85 grams/tonne Silver, and 3.48 grams/tonne Gold. The true thickness of the zone is 9.2 metres based on core angles with the zone dipping north at 45 – 50 degrees.
This eastern phase of the main zone is more zinc rich and lower in copper, which is typical of a zoned VMS system, and this zoning may be extenuated by stretching of the sulphide zone by shearing.
A high gold value of 28.70 grams per tonne was obtained within this zinc rich section hosted in sericite schists that contained the green chromium mica called fuschite. This mineral is often associated with gold bearing systems.
A Mise-a-la Masse survey is underway on the main Zone to trace the outline of the copper rich phase on the west end, 300 m west of drill hole MAR-06-09.
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. 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. More details are available on all of East West’s properties at www.eastwestres.com.
About the Marshall Lake Project:
East West Resource Corporation holds a 50% interest in the Marshall Lake Copper Zinc VMS project located 310 kilometres north of Thunder Bay, Ontario, Canada.
The Marshall Lake area was explored between 1954 and 1996 and resulted in the discovery of a series of high grade near surface copper zinc deposits.
East West and its 50% partner Eyeconomy Holdings PLC now consider that they have control over the Marshall Lake base metal camp with an exploration area of more than forty-three square miles under option.
The partner’s long-term strategy is to define and develop near surface base metal resources on the property while considering the deeper potential of the property as the database is developed.
Two historical inferred mineral resource estimates are available from previous work based on an area within the property called the Main zone located 4 km northeast of the Gazooma copper zone:
K Zone (Main zone)
- 240,000 tons of 1.45% copper, 4.76% Zinc, 2.8 ounces silver, 152 m long to 96 m depth D. W. Sullivan (1969) based on 15 holes
103 Zone (Main zone)
- The 103 zone is an eastern extension of the "K" zone and was estimated to contain 1,174,810 tons (delineated from 57 drill holes) grading 0.82% copper, 2.71 % zinc, 1.77 ounces silver, 0.006 oz. gold. A. S. Bayne (1970).
Both the work by Sullivan and the work from A. S. Bayne were completed prior to NI43-101. All of the exploration results disclosed as mineral resource estimate immediately above are historic in nature and do not presently conform to National Instrument 43-101 Standards of Disclosure for Mineral Projects. They have been reviewed, but not verified, by Robert S. Middleton, PEng, who is the company's designated qualified person and responsible for the verification and quality assurance of its exploration data and analytical results. In the opinion of the qualified person, based on the information available, the mineralization on the Main or "K" Zone would be classified as an Inferred Mineral Resource based on the definition by the CIMM, since it will be required to do further in-fill drilling to establish grades. Therefore, the historic figures should not be relied on.
The property became accessible after 2000 following the completion of all weather roads by logging operators. Road access now permits the deployment of heavy digging equipment, modern geophysical tools and significantly reduces exploration costs. During the second half of 2006 the joint venture partners built a network of drill access trails focusing on exposing the existing showings.
The joint venture partners will each contribute 50% to ongoing exploration expenditure
