Brookbank East

Introduction

The Brookbank East gold property is located approximately 25 km east from the Town of Beardmore and 55 km west from Geraldton. Year-round access to the property can be gained by Trans-Canada Highway 11 and then by boat or snow mobile from former Secondary Highway 801 or from the Kinghorn Road. The property is owned 100% by Alto Ventures and consists of 63 claim cells covering approximately 1,300 hectares.

Geology and Mineralization

The Brookbank East gold property is situated in the Beardmore-Geraldton greenstone belt south of the Pain Lake Fault . The property lies along an easterly trend of numerous gold occurrences, one of which is the Brookbank Gold Deposit situated approximately 15 km west of this project. The Brookbank Deposit is reported to include open-pit Measured and Indicated Resources of 2.64 million tonnes averaging 2.02 g/t Au and containing 172,000 ounces. Underground resources are reported to include Measured and Indicated Resources of 1.86 million tonnes averaging 7.21 g/t Au and containing 430,000 ounces of gold (www.premiergoldmines.com).

The Brookbank Gold Deposit is located at or near the sheared contacts between mafic volcanic rocks and metasediments, including a large component of polymictic conglomerates. Gold mineralization occurs with multiple quartz-carbonate stringers, veinlets and/or stockworks that give rise to broad zones of mineralization 20 to 50 m wide closer to surface and continuing to 700 m depths. Alto's Brookbank East is underlain by easterly trending mafic volcanic rocks in contact with a sequence of polymictic conglomerate units from 300 m to 700 m thick. Results from some of the historical work include 10 g/t Au over 0.91 m intersected in a 1992 drill hole at the southeast end of the Brookbank East property. Grab samples up to 7.68 g/t Au were obtained in 1988 from altered quartz veins in historical trenches near the centre of the property. Some of these trench areas were drilled in 1998.

Records from the diamond drilling in the government assessment files indicate that favourable geology and alteration similar to the Brookbank Gold Deposit were intersected but no sampling was carried out at the time of the 1998 drilling. Brookbank East Project, Ontario
