Notes to accompany Table - Western Tanami Resources as at June 2010
- •The Mineral Resource Estimate is reported at a 1g/t Au lower cut-off.
- •Tonnes are rounded to the nearest thousand and grade to 0.1g/t. Rounding may affect tallies.
- •Deposit ounces rounded to nearest thousand. Stockpile ounces rounded to nearest hundred.
- •Resource estimation of Coyote and Sandpiper deposits was completed by Mr Steven Nicholls, a full time employee of Tanami Gold NL.
- •The Kookaburra Resource estimation was conducted by Mr Peter Ball of DatageoGeological Consultants.
- •The Pebbles Resource estimate was completed in 2007 by Mr Malcolm Titleyof CSA Australia Pty Ltd.
- •Mr Nicholls (MAIG), Mr Ball (MAusIMM) and Mr Titley(MAusIMM, MAIG) qualify as Competent Persons as defined by the December 2004 edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code) and have given permission for the inclusion in this report of the matters based on their information in the form and context in which it appears.
- •The Resource estimations were completed using Micromine, Surpacand Dataminesoftware, comprising an inverse distance grade interpolation within block model constrained by 3D wireframedgeological boundaries. The wireframes defining the mineralisation were based on structural, assay and lithologicalinformation. Various top cuts have been applied to the drill hole samples based on lode domain analysis, with the exception of Kookaburra where the effect of top cutting was deemed immaterial. Where top cuts were applied they ranged from 35g/t for Sandpiper to 120g/t for Coyote.The search constraints applied to the grade estimation were controlled by the orientation of the lodes and the known dip and plunge of the mineralisation within the lodes based on geological knowledge and mining experience.
- •The Resource estimations used bulk density measurements conducted on a deposit scale and broken down by regolith profile. As such the density measurements applied were based on test work applicable to the deposit of interest. These ranged from 2.00 t/m3(base of transported) to 2.72t/m3(Fresh rock).
- •The Resource has been depleted for mining undertaken at the Coyote, Sandpiper and Kookaburra mines during the period 1 July 2009 to 30 June 2010.
- •The Measured Resource at Coyote has been based on the high level of confidence of the location and grade of mineralisation between the current underground development drives. The development drives have typically six metres separation. The Sandpiper and Kookaburra Measured Resource has been based on a 10 metre distance below the current pit floor, which is supported by a combination of mining at the base of the pits, and five metre deep grade control drilling below the floor of the pit.
