GlobeStar Mining Corporation Cumpi� Sector – Cumpi� Hill Nickel Laterite Project in the Dominican Republic:

 

New Mineral Resource Estimate and Metallurgical Testwork Reporting Nearly 90% Nickel Recovery

 

Toronto, Ontario – November 29, 2007 – GlobeStar Mining Corp. (TSX-GMI) (“GlobeStar” or the “Company”) is pleased to announce the completion of a National Instrument (“NI 43-101”) compliant Technical Report that discloses a Mineral Resource estimate and the result of preliminary metallurgical test work for the Cumpi� Sector of its Cumpi� Hill nickel laterite project in the Dominican Republic. An Indicated Resource of 3.0 million tonnes grading 1.5 % nickel (“Ni”) and an Inferred Resource of 2.5 million tonnes grading 1.5 % Ni were estimated at a cut-off grade of 1 % Ni by Snowden Mining Industry Consultants Inc. (“Snowden”), as summarized in Tables 1 and 2. Results of preliminary metallurgical leach test work by SGS Mineral Services in Lakefield, Ontario (“SGS Lakefield”) on material from this deposit show Ni extraction nearly 90% in the transition and saprolite samples. This work is summarized in Tables 3 and 4 below in this release.

 

“This Mineral Resource estimate announced today represents an excellent initial result for building a strong nickel Resource on our properties in the Dominican Republic”, stated Bill Fisher, CEO of GlobeStar.  Fisher added “the Loma Mala Sector Resource estimate is expected to yield an increase in resources of the complex”.

 

JP Chauvin, President of GlobeStar commented: “The metallurgical results are very encouraging for us and allow us to start looking to alternative ways of processing the nickel mining project; the proximity of the Cumpi� Hill to the Cerro de Maim�n project and Falcondo smelter controlled by Xstrata Nickel is definitely an asset.  These existing infrastructure will allow GlobeStar to optimize the economics of the project will provide us with technical and operational synergies as we move forward”.

 

GlobeStar discovered Ni at Cumpi� Hill early in 2006 and finished a regular spaced drilling program in July 2007. Since the discovery of Ni at Cumpi� Hill, GlobeStar has focused  its Ni exploration program in the northern part of the 43 km long  (198 sq km) segment of the Dominican Republic ultramafic laterite belt that it controls, as shown in Figure 1.  The rest of this belt is controlled by Falcondo (Xstrata Nickel). Cumpi� Hill is immediately adjacent to the Falcondo Ni laterite mine, 8 km from the Falcondo smelter and 5 km from the Cerro de Maim�n Project.

 

The Mineral Resource estimates, completed by Snowden are based on the results of 75 NTW and HQ3 core drillholes (2015 m), nominally spaced on 71 m centres, completed between May 2006 and July 2007 on the Cumpi� Sector of the Cumpi� Hill Project, as shown in Figure 2.

 

The results of the leach test work completed by SGS Lakefield are based on bottle roll testing of ten composite samples prepared from crushed core analytical reject materials from selected holes in the Cumpi� Sector. Two limonite zone, four transition zone (soft serpentine) and four saprolite zone (hard serpentine and serpentinized peridotite) samples were prepared and the composites subject to simple bottle roll type leach tests in which the bottles were rolled for 1 minute of every hour for a total of 28 days. The leach tests were carried out at 30% solids by weight. Solution samples were periodically withdrawn to complete free acid titrations and re-adjust to the target acid level of 75 g/L H2SO4. The transition and saprolite zone composites leached well with nearly 90% Ni extractions. Cobalt extractions are estimates due to the low level of cobalt within the samples. The limonite sample did not leach effectively under bottle roll conditions. Based on these results, further test work is warranted aimed at improving the ability to leach limonite; maximizing the nickel and cobalt selectivity versus iron and aluminium; and reducing the overall acid consumption.

 

Additional scheduled work on GlobeStar’s Ni properties in the Dominican Republic currently includes undertaking a Mineral Resource estimate for the Loma Mala Sector using the completed 71 m x 71 m core drilling; reconnaissance drilling in the Corozal area (about 3 km East of Cumpi� Hill); and completion of the reconnaissance for additional target areas of laterite development within Mining Block C1 and the other GlobeStar mineral concessions in the Dominican laterite belt as shown in Figure 1.

 

The Company will file the NI 43-101 compliant Technical Report detailing the Mineral Resource estimates in the Cumpi� Sector co-authored by F.R. Billington, P. Geo., Consulting Geologist, and A.M. Trueman, P.Geo. (CP), Divisional Manager of Snowden, shortly.

These estimates must be read in conjunction with the details of the Mineral Resource estimate methods and the other parameters and assumptions used as described in the NI 43-101 Technical Report for the Cumpi� Sector when released and summarized below:

 

          Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability.

          The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

          It is uncertain if further exploration will result in upgrading the Inferred Mineral Resource to an Indicated or Measured Mineral Resource or the Indicated Mineral Resource to a Measured Mineral Resource category.

          Figures have been rounded and this may have resulted in minor discrepancies.

          The most likely cut-off grade for this deposit is not known and will need to be confirmed by the appropriate economic studies.

          The Mineral Resources were estimated by ordinary kriging into three-dimensional (3D) block models that identify the limonite, soft serpentine, hard serpentine and serpentinized peridotite horizons within the laterite profile.

          Sample preparation was undertaken at the Falcondo Mine laboratory, Dominican Republic and at SGS Lakefield, Canada.

          The majority of the samples (1604) were analysed by SGS Lakefield, Canada. A minority (63) were analysed by the Falcondo Mine laboratory, Dominican Republic.

          Full Quality Assurance/Quality Control procedures were implemented for the samples analysed by SGS Lakefield, including the insertion of standards, duplicates and blanks.

          Bulk density factors from measurements by GlobeStar on core samples from individual horizons from the Cumpi� Sector were applied to all the estimates.

          A Mineral Resource classification scheme has been applied for reporting the estimates that reflects the requirements of NI 43-101, and the CIM Standard Definitions.

 

The data were validated by F.R. Billington, P.Geo., Consulting Geologist and A.M. Trueman, P.Geo. of Snowden , both Qualified Persons as defined in N 43-101.  The Mineral Resource estimates were prepared by A.M. Trueman P.Geo. of Snowden, an independent Qualified Person as defined in NI 43-101.

Geology and mineralization of Cumpi� Hill

Two main areas of laterite development have been identified in the Cumpi� Hill Project area to date (See Figure 2). These are designated the Cumpi� Sector and the Loma Mala Sector. The evaluation of the Cumpi� Sector is the most advanced and is the subject of this press release. The description and the results of the Mineral Resource estimate of the Loma Mala Sector will be the focus of a future report.

 

The Cumpi� Sector consists of three dismembered areas of laterite. Together, they cover an area of 331900 m2 with a combined strike length of about 1250 m in a north-south direction and an average width of 300 m in west-east direction. The thickness of the laterite profile ranges from 2 m to 40 m with an average thickness of 20 m.

 

Limonite, transition, and saprolite horizons are developed in the Cumpi� Sector; however the limonite is generally less well developed/preserved than the transitional and saprolite zones. The laterite/ultramafic bedrock contact is generally transitional and barren rock remnants/boulders are common in the laterite profile.  The geology is similar to the adjacent Falcondo mine.
