West Omai Inferred Gold Resource Increases to 1.65Moz

/NOT FOR DISTRIBUTION TO U.S. NEWS WIRE SERVICES OR DISSEMINATION IN THE UNITED STATES./

PERTH, Australia, Feb. 7, 2013 /CNW/ - Azimuth Resources Limited (ASX and TSX: AZH) (the "Company" or "Azimuth") is pleased to announce a 35% increase in its JORC code and National Instrument 43-101 compliant gold resource estimate for the Smarts and Hicks deposits at its flagship West Omai gold project in Guyana. The resource has been independently estimated by global mining consultancy RungePincockMinarco Limited.

The Inferred Mineral Resource estimate at West Omai for the Smarts and Hicks deposits at a cut off of 1.0g/t Au is now:

  • 16.7Mt @ 3.06g/t Au for total contained gold ounces of 1.65 million ounces.

(The previously announced Inferred Mineral Resource (31st May, 2012) at a cut off of 0.5g/t Au was 12.4Mt @ 3.1g/t Au for total contained gold ounces of 1.22 million ounces).

The Inferred Mineral Resource estimate for the higher grade Smarts deposit at a cut off of 1.0g/t Au is now:

  • 8.1Mt at 4.15g/t Au for total contained gold ounces of 1.08 million ounces.

(The previously announced Inferred Mineral Resource (31st May, 2012) for the Smarts deposit at a cut off of 0.5g/t Au was 5.0Mt @ 4.6g/t Au for total contained gold ounces of 0.75 million ounces).

This resource estimate has resulted from the interpretation of results of drilling completed to November 2012.  Both the Smarts and Hicks deposits remain open at depth and along strike. 

The Company is continuing its exploration program, targeting resource extensions, the Larken prospect and other prospective targets in its extensive landholding at West Omai.

RungePincockMinarco Limited (ASX:RUL) has completed an updated National Instrument 43-101 and JORC Code compliant resource estimate for the Smarts and Hicks gold deposits at the West Omai Project in central Guyana on behalf of Azimuth Resources.

Both deposits are hosted in Proterozoic greenstone belts associated with major northwest trending, sub-vertical to steeply southwest to northeast dipping shear zones. The shear zones have preferentially developed along lithological contacts within a greenstone succession comprised of interflow sediments, mafic to intermediate volcanics and mafic to intermediate volcaniclastics.  Both the Hicks and Smarts deposits are located 100-400 metres to the north of and parallel to the contact of the greenstone succession with the Eldorado Batholith, a regional-scale granitoid intrusive. The extent of artisanal workings in the area suggests that the shear zones are mineralised for a length of at least 12km.

Numerous, moderately well-defined gold-rich lenses, typically 10-15 metres wide, occur within the shear zones and are characterized by anomalous quartz and quartz-carbonate veining, quartz flooding, shearing, chloritisation, minor seritisation and pyritisation. Visible gold and the majority of gold values typically occur within and along margins of quartz veins, in silicified porphyry and granitic dykes, and in adjacent, sheared and pyritised, mafic and intermediate volcanics. Pyrite is common at up to 3% by volume, with local, trace amounts of chalcopyrite, galena and sphalerite, associated with auriferous quartz veins.

The overall Inferred Mineral Resource estimate at West Omai for both the Smarts and Hicks deposits now stands at 16.7Mt @ 3.06g/t Au for total contained gold of 1.65 million ounces, an increase of 35% in contained gold over the maiden resource announced in May 2012.

Table 1: Mineral Resources - West Omai Projects, Guyana - shown for 0.5g/t Au, 1.0g/t Au and 2.0g/t Au cut-off grades. Methodology for the mineral resource estimates will be contained in a NI43-101 report which will be released on SEDAR within 45 days.

Smarts Deposit
The Smarts deposit is a high-grade near surface gold deposit 100% owned by Azimuth Resources. Drilling by Azimuth indicates this deposit may continue at depth and along strike.

The Mineral Resource estimate is for gold mineralisation along a strike length of approximately 2,800m. The resource is comprised of 15 wireframed mineralised bodies within the shear zone each representing a discrete lode (see Figure 1). Wireframes were built using interpreted mineralised structures rather than a grade boundary as used in the May 2012 resource estimate, leading to a more robust estimate.

A block model was built of the mineralisation and Ordinary Kriging grade interpolation was used for the estimate. Statistical analysis determined that a high-grade cut of 30g/t to 80g/t Au (different for each lode) was appropriate for the mineralisation. RUL considers that geological and mineralisation continuity has been demonstrated with sufficient confidence to allow the Smarts deposit to be classified as an Inferred Mineral Resource.

Drill holes used in the resource estimate included 95 diamond holes and 154 RC holes for a total of 2,334m contained within the resource wireframes. Holes were drilled at 20m to 80m spacings on 25m to 220m spaced north-east south-west orientated drill sections. All drilling has been completed by AZH since 2011.

At a 1.0g/t Au cut-off the overall Smarts Inferred Mineral Resource is estimated at 8.1Mt @ 4.15g/t Au for total contained gold of 1.08 million oz.

Within this estimate there are a number of areas of mineralisation which grade significantly higher than the average grade. The largest lode represents over 80% of the contained ounces.  The higher grades in the deposit start from surface, as shown in Figure 2.

The Smarts resource remains open at depth.  There are higher grade zones and shoots within the Smarts Deposit, imbedded within lower grade mineralisation (1-10 g/t x metres). This low grade mineralisation remains open along strike in both directions and remains to be drill tested. Potential therefore exists for the discovery of further higher grade zones and shoots along strike from the Smarts resource.

Hicks Deposit
The Hicks deposit is a near-surface deposit 100% owned by Azimuth Resources, located 2km southeast of the Smarts deposit.

The Mineral Resource estimate is for gold mineralisation along a strike length of approximately 2,900m. The resource is comprised of 21 wireframed mineralised bodies within the shear zone each representing a discrete lode (see Figure 3 below). 75% of the resource ounces are included in three of these lodes. Wireframes were built using interpreted mineralised structures rather than a grade boundary as used in the May 2012 resource estimate, leading to a more robust resource estimate.

A block model was built of the mineralisation and Ordinary Kriging grade interpolation was used for the estimate. Statistical analysis determined that a high-grade cut of 20g/t Au was appropriate for the mineralisation contained in lodes representing the majority of the deposit. RUL considers that geological and mineralisation continuity has been demonstrated with sufficient confidence to allow the Hicks deposit to be classified as an Inferred Mineral Resource.

Drill holes used in the resource estimate included 81 diamond holes and 62 RC holes for a total of 2,002m within the resource wireframes. Holes were drilled at 25m to 60m spacings on 15m to 100m spaced north-east south-west orientated drill sections. The resource estimate consists of drilling completed by AZH between 2010 and 2012 as well as drilling completed during the 1990s by Cambior Inc. and Cathedral Gold Corp.

At a 1.0g/t Au cut-off the overall Hicks Inferred Mineral Resource is estimated at 8.7Mt at 2.05g/t Au for total contained gold of 571,000 ounces.

The data used to estimate the Hicks and Smarts resources has been independently verified by Mr Aaron Green, the Competent Person (and Qualified Person) signing off on the Mineral Resource estimates.

Independent verification of data was carried out during site visits undertaken by Mr Green (Manager-Geology Consulting Australia) in October 2010 and November 2012 and by Mr Rod Ogilvie (Registered Associate of Runge Mining (Canada) Limited.) in December 2011.  This process included reviewing on-site drilling, logging and sampling procedures, QAQC procedures, verification of drill hole collar locations (using a hand-held GPS) and down hole survey methods. RUL personnel personally visited the analytical laboratory in Guyana and viewed the sample reduction, assay and data collection and recording practices.  In addition, under the supervision of Mr Green, drilling and sampling information provided to RUL was validated against the original data.

The data verification process was very thorough and drilling, sampling and assaying procedures are acceptable and well developed to industry standards. The data verification process carried out by RUL has confirmed the integrity of the data.
