JORC Report
JORC Report PT. Bintang Delapan Mineral, Nickel Project
BSA has updated the JORC report 2012, and provided supervision and monitoring exploration conducted by PT. Bintang Delapan Mineral. The updated JORC report is a revision of 2012 JORC report made also by BSA, where the specified update reserves estimation is in accordance with the JORC code 2004. The result would give are option in funding the project as IPO, raising fund, and pre-feasibility study stage.
JORC Report PT. Gama Group Limestone Project
BSA provided drilling supervision, topographic survey, QAQC sampling, and mineral resources estimation comply with JORC code 2004 for limestone bayah project owned by PT. Gama Group. BSA eleveted the PT.Gama previous exploration into JORC Code best practice. The project was started in November 2012 to confirm the old drilling campaign with twin hole programme. Eight holes had been completed and continuing with infill drilling programme to increase the level of confident with 200x200m spacing of total 1,000m depth. The result would give an option in funding the project as IPO, raising fund, and pre-feasibility study stage. The surface mapping is also conducted to check the old mapping result in term of delineate the area of limestone exporsure on the surface. BSA has completed JORC report for PT.Gama group in June 2013.
JORC Report PT. TRIUTAMA DASA INDONESIA
BSA started drilling and JORC Technical Report in Cihara Limestone Project of PT TRIUTAMA DASA INDONESIA from July 17th until September 18th 2013 using Jacro 200 Triple Tube HQ Drilling. There are 11 holes resulted within 3 blocks with total core production of 638.5 meters. There are five type of limestone revealed in this area. A completed 2D and 3D block models based on drilling data are generated. The models are used to provide grade and tonnage estimates for mineral resource computation. Simplified geological coding was applied to the Cihara Project database for limestone layer definition. The main steps of the resource estimation process were as follows: Construct lithology geological DTM surface models; Generate unconstrained three dimensional resource block models; and Validate the resource block model with primary data. BSA has assigned the Cihara resource estimates to Inferred Mineral Resources Categories at TDWI block and to Exploration Result at TCI and TPI blocks based on the current information available. No Measured and Indicated Mineral Resources have been defined in the current Mineral Resource Estimate.
JORC Report PT. IFISHDECO
BSA started drilling and JORC Technical Report in Tinanggea Nickel Project of PT IFISHDECO from February 29th until April 25th, 2011 using Jacro 200 Triple Tube HQ Drilling. There are 164 holes resulted within 2 blocks with total core production of 2854 meters. A completed 2D and 3D block models based on drilling data are generated. The models are used to provide grade and tonnage estimates for mineral resource computation. Simplified geological coding was applied to the Tinaggea Project database for laterite layer definition. The main steps of the resource estimation process were as follows: Construct lithology geological DTM surface models; Generate unconstrained three dimensional resource block models; and Validate the resource block model with primary data. BSA has assigned the Tinanggea resource estimates to Measured Mineral Resources Categories at S1 block, Indicated Mineral Resources Categories at South block, and Inferred Mineral Resources Categories at North block.
JORC Report PT. Panca Raja Perkasa Bauxite Project
BSA provided the JORC technical report 2012 with reviewed and analyzed data provided by PT. Panca Raja Perkasa of ketapang bauxite project. There are 306 pits holes resulted with total pits production of up to 1500 meter. A completed 2D and 3D block model using gemcom surpac model based on testpit data are generated. The model are used to provide grade tonnage estimates for mineral resource computation.
The main steps of the resource estimation process were as follows : construct lithology geological DTM surface model ; generate unconstrained three dimensional resource block model. BSA has classified and estimated the Ketapang Bauxite Project consists three categories reporting as Inferred Mineral Resource are applied to the ketapang bauxite with small and medium testpit spacing of 50-100 m, Exploration Results was achived using a polygonal resource estimation methods of utilizing voronoi polygons ,constaining the extent of the bauxite using digitized polygons based on the topography and by distance of influence and Exploration target estimation based on geological mapping data . The result would give are option in funding the project as IPO, raising fund, and pre-feasibility study stage.
JORC Report PT. Makmur Lestari Primatama, Nickel Project
BSA started drilling, topography detail, QAQC sampling and JORC technical report in Lameruru Nickel Project of PT Makmur Lestari Primatama from November 2014 until September 2015 using Jacro 200 triple tube HQ drilling. There are 723 holes resulted with total core production of up to 25,000 meter and BSA do perform a geostatistic drilling in Bintaro Block for implementation indication maximum of range spacing drilling. A completed 2D and 3D block model using gemcom surpac model based on drilling data are generated. The model are used to provide grade tonnage estimates for mineral resource computation. The main steps of the resource estimation process were as follows : construct lithology geological DTM surface model ; generate unconstrained three dimensional resource block model and validate the resource block model with ordinary krigging methods. The parameter validation data block model with refrence visual check, krigging efficiency and krigging variance to raise the level of confidence in the results of model calculation.
