Mr. Henry Ewanchuk reports
Assay results have been received from the second phase of the 1999 diamond drilling on its
100-per-cent-owned Sheraton-Timmins property, near Timmins, Ont. The highlight of the 1,338-metre
program was the extension down dip of the zinc-silver mineralization at the northeast end of the Cross
Lake zone thereby enhancing the possibility for open pit exploitation in this area.
Of the five holes drilled, three (CLS99-73, 74 and 75) were successful in expanding the zinc/silver
mineralization in the Cross Lake zone. Additional drilling is definitely warranted in this area in order to
further delineate the full extent of this zone. Significant intersections are as follows:

Assays continue to be carried out by ASL Chemex of North Vancouver, B.C. Drill core is routinely
analyzed by ICP AES methods for 32 elements including copper, lead, zinc and silver and by fire
assay-AAS procedure for gold. Check assays will be run on selected samples by another independent
laboratory.
A drill hole plan, longitudinal section and cross section, are available by fax upon request.
Hole CLS99-73 intersected zinc-silver mineralization 45 metres below CLS97-4 and 110 metres
northeast of CLS97-16. The zinc mineralization is hosted in a grey felsic tuff with some pyrite-chert
affiliation as well as a yellow sericitic tuff containing numerous chert pyrite bands. It has been delineated
to a down dip length of 145 metres in this area (refer to cross section). The results indicate there is
continuation of the zinc-silver horizon to the east and down dip from CLS99-73 which will require
further drilling.
Hole CLS99-74, collared 35 metres east of hole CLS 98-49, was drilled to test the near surface
up-plunge of the zinc-silver mineralization previously outlined in the 40 series of holes (CLS98-40 to
49). This hole intersected 42.5 metres (from 50 to 92.5 metres) of zinc (sphalerite) mineralization with
narrower higher grade sections associated with chert pyrite zones.
Hole CLS99-75 intersected zinc (sphalerite) mineralization 40 metres below CLS97-21 and 30 metres
east of CLS97-16, hosted in a grey tuff/lapilli tuff horizon with pyrite and minor chert, a grey rhyolite
tuff with no chert and a sericite schist with numerous chert pyrite bands. This hole helps link the
zinc-silver mineralization from hole CLS97-16 to CLS99-73 as the grey tuff host rock can now be traced
eastward. This was not previously detected in the nearer to surface 40 series of holes.
Holes CLS99-71 and 72, drilled northeast of the Cross Lake zone for geological purposes, were
successful in expanding the known extent of favourable host rock for VMS deposits. Hole CLS99-71
was drilled 1,100 metres northeast of hole CLS97-16. The hole intersected favourable rock for VMS
deposits consisting of felsic tuffs/breccias, rhyolite, and chert with mineralization consisting of
disseminated to semi-massive pyrite and minor chalcopyrite and sphalerite similar to the host rock of the
Cross Lake zone. Drill hole CLS99-72 was drilled 550 metres to the northeast of hole CLS97-16 to
complete the geologic stratigraphic section in conjunction with CLS98-66. Although no significant
economic mineralization was encountered in either hole, the presence of the wide spread felsic (rhyolite)
pile to the northeast indicates that there is a large under-explored area favourable for hosting VMS type
deposits.
The company is in the process of arranging to have preliminary metallurgical testing conducted on
zinc/silver and copper/silver samples taken from the Sheraton-Timmins property. Results will be released
when they become available.
