Copper Mineralization Extended at G Zone, Marshall Lake Property
- Copper values range from 1.60% to 11.85%
- Silver values range from 45 grams per tonne to 324 grams per tonne
- Gold values range from 0.54 grams per tonne to 1.26 grams per tonne
East West Resource Corporation (TSX-V: EWR) and Eyeconomy Holdings PLC (UK-PLUS: EYE) announce that additional trenching for 75 m has yielded 6 additional grab samples to the southeast of the G-2 trench that was previously reported on December 8th, 2006. The consistently high copper values correlate with silver and gold values. (Samples were taken at 8 – 11 metre intervals at random along the trend).
IP surveys suggest this zone extends beyond 300 m. A Mise-a-la-masse survey will be attempted to look for a down plunge lense. The lower zinc values suggest the G zone is part of a lower "Stringer" phase to a VMS system.
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.
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.
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.
East West and its 50% partner Eyeconomy Holdings PLC now consider that they have control over the whole Marshall Lake base metal camp with an exploration area of more than forty-three 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 and 2.5km northwest of the G 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 joint venture partners will each contribute 50% to ongoing exploration expenditure.
