Second New Zinc Zone at Marshall Lake Marks Extensive VMS System
- Grab samples range from 0.36% to 16.15% Zinc and 0.01% to 7.03% Lead
- Large fold links Zinc rich VMS Zones
- Six Zinc rich Zones now identified
East West Resource Corporation (TSX-V: EWR) and Eyeconomy Holdings PLC (UK-PLUS: EYE), 50:50 joint venture parties, announce that trenching near the "D" copper stringer zone located 2 km west of the Main Billiton zone has exposed a Zinc-Lead rich sulphide phase suggesting that another complete VMS (volcanogenic massive sulphide) zone may occur in an area previously thought to be solely a copper stringer zone. Grab samples from the outcrop and trench yielded the highest Lead (Pb) values seen on the property to date.
This style of mineralization is of the type that occurs at five other showings on the property including the North Diabase, Main Billiton, South Zone, Open Pit and a new zinc showing east of Teck Hill (see NR December 13, 2006). This pattern of zinc and lead occurrences suggests a large regional fold structure controls the location of the mineralized Marshall tuff horizon which hosts the base metal mineralization.
This folded horizon now generates a number of previously unexplored areas on the property that have high potential for basemetal mineralization.
Geophysical surveys are now in progress to cover these potential sites and extend the shape and extent of the D Zone. The Marshall Lake property covers a large 13 by 7 km area and consists of 690 claim units (over 11,000 hectares) and is roughly the size of the central part of the Noranda basemetal Camp which contained 31 former producing copper-zinc-gold-silver mines with 80 years of production.
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 became interested in the property in the second half of 2005. Negotiations to option four hundred and ten claim units from a local prospector were concluded in June 2006. A further eighty-six leased and nine staked claims were acquired from N.W.T. Copper Mines Limited in October 2006. Finally three remaining claims were optioned from Teck Cominco in December 2006. The JV partners now consider that they have control over the Marshall Lake base metal camp with an exploration area of more than forty –eight square miles under option.
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 is 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
Historical drilling by Kendon Copper in 1962 and Imperial Oil in 1976 intersected copper values 100 m to the north west of the Zinc-Lead bearing trench which indicates the Copper stringer phase.
