Kentor Gold Limited (“Kentor Gold” or “the Company”) is pleased to announce an updated resource estimate at the Jervois Copper-Silver-Gold Project in the Northern Territory. This follows completion of the recent drilling campaign at the Reward and Bellbird prospects.

The total Resource has increased to

13.5 Mt @ 1.3% copper and 25.8 g/t silver containing 170,416 tonnes of copper and 11.6 million ounces of silver, a 13% increase in copper and 20% increase in silver, based on a cut-off grade of 0.5% copper (Table 1).

Including a maiden gold Resource of 69,000 oz

Exploration Potential for the Reward and Bellbird deposits in areas adjoining the current Inferred Resources is 5 – 10Mt @ 1 to 1.3% copper and 10 to 25g/t silver at a 0.5% copper cut off (for 50,000 to 100,000 tonnes copper and 3 to 5Mozs silver).

Kentor Gold Managing Director Simon Milroy commented:

“These increased and upgraded Resource Estimates represent a major advance in the bankable feasibility study now being prepared towards mine development at Jervois.

“Most of the Resources are now in the Indicated Category, increasing our confidence in the Project.

“During the drilling programme a number of parallel zones of mineralisation to the main mineral body were encountered which require further drilling to establish if additional resources can be delineated.

“All mineralised zones remain open along strike and down dip.

“At the same time, the increased Resource Estimate 6km away at Bellbird highlights the potential scale of Jervois - its extensive strike length as well as new areas of mineralisation still yet to be explored. “

The Jervois project was acquired in May last year and since this time Kentor Gold has successfully increased the resource estimate in three stages as shown in Figure 1.

Figure 1 Growth in Copper and Silver contained metal in resource

The Jervois Base Metal Project comprises four main areas of economic interest, namely Marshall-Reward, Green Parrot, Bellbird and Bellbird North. Each area has sufficient drilling for the identification of a mineral resource. Marshall-Reward (Cu-Ag) and Bellbird (Cu) are essentially copper (+silver) deposits with a more polymetallic nature to the Green Parrot and Bellbird North deposits. A location map of the deposits with the regional geology is included as Figure 2.

Gold grades for Marshall-Reward and Bellbird have been included in the resource estimates for the first time. The amount of historical gold data is limited and as a result the gold resource estimate is classed as Inferred. A combined resource estimate for the two areas amounts to 12.7Mt @ 0.17g/t for 69,000ozs at a copper cut off of 0.5%.

A long section through Marshall and Reward is shown in Figure 3 and includes all the holes used in the resource estimate.

Figure 3 Marshall-Reward Copper Block Model Distribution Long Section of Indicated & Inferred Resource

(green circles = pierce points of drill holes)

Exploration Potential for both deposits has been defined as interpolated block grades within the interpreted mineral wireframe using a larger search strategy. It consists of areas peripheral to the current Inferred estimates within the interpreted mineral wireframes, unconstrained by depth. This is interpreted to be a combined total for Reward and Bellbird of 5.0 – 10.0Mt @ 1 to 1.3% Cu and 10 to 25g/t Ag at a 0.5% Cu cut off (50,000 to 100,000 tonnes Cu and 3 to 5Mozs Ag). The deposits are open at depth and there are additional possibilities along strike from the deposits based on interpretation of the detailed SAM geophysical survey.

The potential quantity and grade of the Exploration Potential is conceptual in nature and there has been insufficient exploration to define a Mineral Resource. It is uncertain if further exploration will result in the determination of a Mineral Resource.

Estimation Checklist (JORC Code and Guidelines)

Estimating and Reporting of Mineral Resources for Marshall-Reward & Bellbird

Database integrity All relevant data were entered into a DataShed database where various validation checks were performed.

Data was exported into an Access Database and linked to Surpac for wireframing and resource estimation. Surpac database audit run to check for errors

Visual reviews were conducted to confirm consistency in logging and drill hole trajectories.

Assessment of the data confirms that it is suitable for resource estimation. Geological interpretation

The Jervois Project is characterised by several elongate structural zones of disseminated copper sulphide mineralisation

Primary copper/silver/gold mineralisation is hosted in arrays of steep/sub-vertical dipping structural zones associated with sulphides and magnetite in the primary zone. Sulphide becomes variably degraded in the oxide zone.

Separate mineral lodes for Reward and Marshall with some 75-100m of overlap suggesting an en echelon structural array.

Bellbird comprises a higher grade Main Lode and a lower grade Hangingwall Lode. Mineralisation envelopes were domained on a 0.1% Cu cut-off grade with some

geological criteria. Polygons and hence triangulations are based on interpretations completed on sections

with strings snapped to drill holes. Oxidation interpretation based on drillhole logging information

Estimation and modelling techniques

1 metre assay composites were used based on mineral wireframes; residual composites <0.5m wide were discarded; 3,481 composites for Reward, 1,879 for Bellbird

Summary statistics indicated moderate coefficients of variations; modest correlation between silver and copper

Top cutting determined from log-probability plots were used; top cuts for gold at Bellbird and silver at Marshall-Reward

Geostatistics were performed for copper, silver and gold within individual mineralised lenses

Variography poor to moderate with low nuggets Ordinary Kriged estimation was used for the mineral zones. Parent block sizes were 2 metres in the X (east) direction, 10 metres in the Y (north)

direction and 10 metres in the Z (RL) direction with no sub-blocking A 3 estimation pass strategy was used with an increasing search radius and decreasing

number of data points for all domains. A second 2 pass search strategy was used to identify exploration potential

The first and second estimation runs used an octant based search where at least 4 octants had to be estimated

Search ellipses were orientated to follow the trends of the individual domains Search distances were 5m by 30m by 30m increasing to 10m by 60m by 60m with the

minimum number of data points of 12 decreasing to 6 and 2 octants. Cut-off parameters Resources have been estimated at a cut-off grade of 0.5% Cu with a partial percent

volume adjustment within the mineral wireframe. The cut-off grade at which the resource is quoted reflects the intended bulk-mining approach.

Bulk density Density based on 1,363 core samples where SG values were determined using the “Archimedes Principle”. Density was modelled using inverse distance squared technique.

Default density values for the oxide and partial oxide zones were generated from collected data and inserted into the block model

Classification Mineral resources have been classified on the search pass category Pass 1 & 2 = Indicated Pass 3 = Inferred.

Gold mineralisation is classed as Inferred based on fewer data points than Cu & Ag, no correlation with Cu & Ag and high variability with low grade standards.

Positive factors for classification include drill spacing, robustness of resource estimates from earlier models, surface mapping for geological continuity, moderate success with twinned holes confirming some of historical assays

Negative factors are accuracy of historical hole locations, different analytical methods over a 40 year period, missing assays values and unsampled sections of historic holes, No QAQC data for historical work, weak variography, no recoveries for RC drilling.

Reviews Results are comparable with previous H&SC resource estimates
