Updated resource calculation for the Chaarat Gold Project

 

Road Town, Tortola, British Virgin Islands (1st April 2014)

Highlights

·    Total Measured and Indicated JORC resource increased by 20% to 3.59 million ounces at a grade of 3.3 g/t (@ 2g/t cut off)

 

·    Measured and Indicated resource of the mostly oxide open pittable Tulkubash Zone increased 95% to 639,171 ounces @ 2g/t (@ 1g/t cut off)

 

·    Total resource (Measured, Indicated and Inferred) decreased by 8.1% from 5.76 Moz to 5.29 Moz due to more restrictive delineation of Inferred category resource*

 

 

Chaarat undertook an infill drilling programme in the 2013 season in order to increase the potential reserves to be delineated as part of the Definitive Feasibility Study (DFS).

Drilling in the shallower, more weathered and therefore more oxidized layer of the deposit was designed to increase the Measured and Indicated resource which will be mined by the open pit method. More material was delineated in the near surface oxide open pittable sections but at a slightly lower grade than the deeper material. The grade of the predominantly underground non-oxide material section of the deposit has been reduced from 4.03 g/t to 3.36 g/t using a 2 g/t cut-off grade. The grade of the shallow oxide and open pittable section of the deposit is currently 1.97 g/t using 1 g/t cut off. The change of grade was also a result of the more conservative approach adopted in the construction of the solid model.

As a result of the additional drilling a larger part of the resource can be categorised as Measured and Indicated. At the same time stricter criteria for inclusion of material in the Inferred category reduced the proportion of Inferred resource from 48% to 27% of the total resource.

It has become apparent that different mining methods will be used to mine the resource so presenting the resource at a single cut-off grade could be misleading. In accordance with current best practice the resource information has therefore been presented at a range of cut off grades.

Chaarat and its advisers believe that it would be prudent to use a cut-off grade of 2.0 g/t for areas of the deposit amenable to bulk underground mining techniques, based on a gold price of $1,250, and industry average bulk underground mining and mill processing costs. 

A cut-off grade of 1 g/t for the open-pit, oxide portions of the deposit, due to lower average mining and processing costs, is considered reasonable. 

Portions of the deposit where lower productivity underground mining techniques would be used are likely to have higher cut-off grades.  A more complete analysis of cut-off grades, costs and recoveries will be undertaken as part of the DFS. The resource model is the basis for the mine design which is currently being prepared by Gustavson.

Dekel Golan CEO of Chaarat commented: "Increasing the Measured & Indicated resource, which is the basis for the mine reserve calculation, by 20% to almost 3.6 million ounces is an outstanding achievement for our team. We are encouraged that the significant amount of oxide material now delineated may reduce costs of initial production. 

It is worth noting that the average grade of large discoveries today is 0.89g/t and the average grade of producing mines is 1.18g/t, significantly lower than that of Chaarat1. This is perhaps the key strength of Chaarat - the potential, once in production, to continue to operate profitably even at a low gold price."

* Based on the considerations above, Chaarat has previously reported its resource using a cut-off grade of 1.0 g/t for the predominantly open pit oxide resource and 2.0 g/t for the mainly underground sulphide material.
For the sake of clarity we have continued to use the same parameters.

* Portions of mineralization at these cut-off grades may not have reasonable prospects for economic extraction under mining and process cost assumptions for this zone, depending on oxidation zonation and mining method, but are included for the sake of completeness.

** Includes M2400, M3000, M34, M39, M44, M50, M60, Contact Project and C40 zones from previous resource statements.

Note:  Table 1 includes the information presented in Tables 2 and 3.

Quantity and grade are estimates and are rounded to reflect the fact that the resource estimate is an approximation.  Mineral resources are not ore reserves and do not have demonstrated economic viability.  There is no certainty that all or any part of the mineral resource will be converted to reserves.  Quantities may not add or multiply due to rounding.

Glossary of Technical Terms

"Au"

chemical symbol for gold

"cut-off"

the lowest grade value that is included in a resource statement.  It must comply with JORC requirement 19: "reasonable prospects for eventual economic extraction" the lowest grade, or quality, of mineralised material that qualifies as economically mineable and available in a given deposit.  It may be defined on the basis of economic evaluation, or on physical or chemical attributes that define an acceptable product specification  

"g/t"

grammes per tonne, equivalent to parts per million

 

"Inferred 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 which may be limited or of uncertain quality and reliability

"Indicated 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

"JORC"

 

 

 

"koz"

The Australasian Joint Ore Reserves Committee Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves 2012 (the "JORC Code" or "the Code").  The Code sets out minimum standards, recommendations and guidelines for Public Reporting in Australasia of Exploration Results, Mineral Resources and Ore Reserves

thousand troy ounces of gold

"Measured Resource"

that part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a high level of confidence.  It is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.  The locations are spaced closely enough to confirm geological and grade continuity

"Mineral Resource"

a concentration or occurrence of material of intrinsic economic interest in or on the Earth's crust in such form, quality and quantity that there are reasonable prospects for eventual economic extraction.  The location, quantity, grade, geological characteristics and continuity of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge. Mineral Resources are sub-divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories when reporting under JORC

"Mt"

million tonnes

"oz"

 

troy ounce (= 31.103477 grammes)

"Reserve"

the economically mineable part of a Measured and/or Indicated Mineral Resource

"t"

tonne (= 1 million grammes)
