-- Leach residue values were all within an acceptable range of 0.08 - 0.15 g/t Au. These returned total extractions ranging from 91.0% to 95.8%
-- Cyanide consumptions ranged between 0.26 and 0.40 kg/t. -- Lime consumptions varied from 0.73 to 1.51 kg/t.

Comminution
-- The Bond Rod Work index (BRW(i) ) was conducted on a -12.7mm feed sample and returned a value of 13 kWh/t;
-- The Bond Ball Work index (BBW(i) ) was conducted targeting a P(80) of 75mm on -3.35mm feed material and returned a value of 18.5 kWh/t;
-- The bond abrasion index (BA(i) ) for the sample was determined as 0.1338 and the material is considered to have relatively low abrasiveness.
Technical Glossary
Au Gold --------------------------- ----------------------------------------------------------------------------------------- Carbon in Leach A recovery process during which a slurry of gold ore, carbon and cyanide are mixed together. The cyanide dissolves the gold content and the gold is absorbed on the carbon; the carbon is subsequently separated from the slurry for further gold removal. --------------------------- ----------------------------------------------------------------------------------------- Comminution The process by which ore is reduced in size in order to liberate the desired mineral from the gangue material in preparation for further processing --------------------------- ----------------------------------------------------------------------------------------- Concentrate The metal-rich product resulting from a mineral enrichment process such as gravity concentration or flotation, in which most of the desired mineral has been separated from the waste material in the ore --------------------------- ----------------------------------------------------------------------------------------- Flotation The process by which the surface chemistry of the desired mineral particles is chemically modified such that they preferentially attach themselves to bubbles and float to the pulp surface in specially designed machines. The gangue or waste minerals are chemically depressed and do not float, thus allowing the valuable minerals to be concentrated and separated from the undesired material --------------------------- ----------------------------------------------------------------------------------------- Grade The proportion of a mineral within a rock or other material. For gold mineralisation this is usually reported as grams of gold per tonne of rock (g/t) --------------------------- ----------------------------------------------------------------------------------------- g/t grams per tonne --------------------------- ----------------------------------------------------------------------------------------- Head Grade The grade of the ore --------------------------- ----------------------------------------------------------------------------------------- Inferred Mineral Resource That part of a mineral resource for which tonnage, grade and mineral content can be estimated with a low level of confidence. It is inferred from geological evidence and assumed but not verified geological and/or grade continuity. It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that may be limited, or of uncertain quality and reliability --------------------------- ----------------------------------------------------------------------------------------- Indicated Mineral Resource That part of a mineral resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. The locations are too widely or inappropriately spaced to confirm geological and/or grade continuity but are spaced closely enough for continuity to be assumed --------------------------- ----------------------------------------------------------------------------------------- koz Thousand troy ounces --------------------------- ----------------------------------------------------------------------------------------- Km Kilometre --------------------------- ----------------------------------------------------------------------------------------- kt Thousand tonnes --------------------------- ----------------------------------------------------------------------------------------- ktpa Thousand tonnes per annum --------------------------- ----------------------------------------------------------------------------------------- m metre --------------------------- ----------------------------------------------------------------------------------------- Mtpa Million tonnes per annum --------------------------- ----------------------------------------------------------------------------------------- Mineral Resource A concentration or occurrence of material of economic interest in or on the Earth's crust in such a form, quality, and quantity that there are reasonable and realistic prospects for eventual economic extraction. The location, quantity, grade, continuity and other geological characteristics of a Mineral Resource are known, estimated from specific geological knowledge, or interpreted from a well constrained and portrayed geological model --------------------------- ----------------------------------------------------------------------------------------- Moz Million troy ounces --------------------------- ----------------------------------------------------------------------------------------- oz Troy ounce, equivalent to 31.103477 grams --------------------------- ----------------------------------------------------------------------------------------- Preg Robbing A characteristic of gold-bearing ore denoting the presence of organic carbon matter which may lead to lower recovery in conventional cyanide leaching. Lower recovery is due to losses of gold absorbed into the organic carbon instead of absorbing into man-made carbon introduced to the slurry in CIL --------------------------- ----------------------------------------------------------------------------------------- Recovery A term used in to indicate the proportion of material obtained in the processing of an ore. It is generally stated as a percentage of valuable metal in the ore that is recovered compared to the total valuable metal present in the ore --------------------------- -----------------------------------------------------------------------------------------
