Trade Winds Files Updated NI 43-101 Technical Report for Block A on SEDAR
On May 26, 2009, Trade Winds released the constrained in-pit mineral resource estimate for the Block A Joint Venture property completed by Watts, Griffis and McOuat (“WGM”). This conceptual pit shell was outlined within the overall mineral resource block model prepared by WGM. The mineral resource estimate within the pit accounted for a total of 1,200,000 oz Au in the indicated category and 277,000 oz Au in the inferred category within the pit at a cut-off grade of 0.5 g/t. This pit shell was selected from a single block model that contained a much larger mineral inventory of gold mineralization along the entire strike length of the M Zone and North Walter Lake Zone utilizing approximately 227,415 metres of diamond drill hole data. An excerpt from the NI 43-101 report prepared by WGM indicates the total mineral inventory contained in their resource model for Block A:
This is in addition to the mineral resource estimate published in the WGM report for the adjacent Gowest property, which contained:
On July 14, 2009, Trade Winds issued the following news release confirming the completion and filing of the report: Trade Winds Files Updated NI 43-101 Technical Report for Block A on SEDAR Vancouver, BC, July 14, 2009, - Trade Winds Ventures Inc. (TSX-V: TWD, FSE: TVR) (“Trade Winds” or the “Company”) is pleased announce that further to the Company's news release dated May 26, 2009, the independent National Instrument ("NI") 43-101 compliant technical report for its Block A property, a 50/50 joint venture with Detour Gold Corporation (“Detour Gold”) located near Detour Gold’s Detour Lake gold project in northern Ontario, has been filed on SEDAR. The mineral resource estimate was completed by Watts, Griffis and McOuat Limited (“WGM”), Consulting Geologists and Engineers of Toronto, Canada and complies with NI 43-101 (“NI 43-101”) Standards of Disclosure for Mineral Projects. The technical report is also available on the Company’s website at www.tradewindsventures.com. The focus of the report is the in-pit mineral resource estimate for Block A presented in Trade Winds’ May 26, 2009 press release and summarized below. This mineral resource estimate is an update of the December 2006 Technical Report by Golder Associates Ltd. and contains data from an additional 53 diamond drill holes totaling 13,095 metres completed in 2007. The 2007 drilling program targeted near-surface gold mineralization of the M Zone in the eastern portion of the deposit, which enabled the use of a Lerch-Grossman pit shell to generate a preliminary in-pit mineral resource.
Notes: (1) The mineral resources are classified as indicated and inferred, and comply with the CIM mineral resource definitions referenced in National Instrument 43-101. (2) Base case assumes a gold price of US$700/oz gold and US$ exchange rate of $1.18. (3) Mineral resources that are not mineral reserves do not have demonstrated economic viability. (4) The quantity and grade of reported inferred resources in this estimation are conceptual in nature and there has been insufficient exploration to define these inferred resources as an indicated or measured resource and it is uncertain if further exploration will result in upgrading them to an indicated or measured resource category. (5) The tonnages and grades quoted are undiluted. Gold grades were capped at values ranging from 10 g/t to 100 g/t based on statistical analysis. (6) Parameters and methodology used are described in Trade Winds’ May 26, 2009 press release and the NI 43-101 technical report. NI 43-101 Compliant Report
