PERTH, Australia, April 30, 2012 /CNW/ - Elemental Minerals Ltd. (ASX, TSX: ELM) ("Elemental" or "the Company") is pleased to provide the following quarterly update.
16 boreholes (4843.59m) were drilled during the quarter for resource
infill and expansion and the hydrological testing programme.
Continued with engineering studies on the process plant, infrastructure
components and mine design.
Received approval or the Terms of Reference for the environmental and
social impact assessment from the Republic of Congo ('ROC') government
regulators and continued with baseline assessments.
- Upgrade of field camp to 150 personnel.
Pre-Feasibility Study and Phase 2 Exploration Programme
The Company continued with the pre-feasibility phase of its definitive feasibility study ("DFS") for the Sintoukola potash project this quarter. The Phase 2 resource drilling was completed. 12 boreholes (3,914 metres) were drilled to bring the final total to for Phase 1 and Phase 2 resource holes to 36 (11,954 metres). Some of these boreholes also served to provide geotechnical samples and data for the PFS.
An additional 4 boreholes (930 metres) were drilled for hydro-geological purposes during the quarter to provide data for the Company's PFS. A further 3 holes are in progress and planned to complete this phase of hydrological study.
Resource boreholes completed during the Quarter with intersections reported are given in Table 1.
Sampling and Analyses
Drill core samples (PQ core diameter sizes) are split in half by a diamond saw cutting machine at the project site. The half split samples, each weighing about three to seven kilograms, are collected at an average interval of 0.3 to 1.0 metre. The samples were processed and analysed by Genalysis, Perth, Australia. Sample preparation and analysis is done by Genalysis. Potassium, Sodium, Calcium, Magnesium, Chlorine, and Sulphur were analysed by ICP-ES. Routine international-standard QA/QC procedures were used by Genalysis. One of the six elements analysed are reported here: potassium (K) and its molecular equivalent of Potassium oxide (K2O, by multiplication with a factor of 1.204). The detection limit for K is 0.001%.
|% K2O||% KCl|
|EK_18||Upper Upper Seam||286.59||290.45||3.86||16.14||25.57|
|EK_18||Lower Upper Seam||290.7||300.26||9.56||20.69||32.78|
Table 1. Drill hole intersections reported during the Quarter. In EK_21 and EK_30 the borehole failed above the expected seam intersection. Complete sample submission for EK_22, EK_24, EK_28 pending. In EK_25 no seam was intersected.
Table 2. Drillholes completed during the Quarter. In EK_21 and EK_30 the borehole failed above the expected seam intersection. Complete sample submission for EK_22, EK_24, EK_28 and EK_32 to EK_36 pending. In EK_25 no seam was intersected.
Pre-Feasibility Trade-Off Studies
The study team consisting of Elemental staff, SRK Consulting, AMEC Americas and EGIS International advanced the Pre-Feasibility study, with good progress having been achieved in the following areas.
Geotechnical study: The field geotechnical drilling and logging was completed. Laboratory testing and engineering characterization was completed. 2D finite element analysis is in progress to determine mine design criteria.
Hydrogeological study: Piezometer testing on 10 hydrogeological holes was completed by SRK (US) during January and February 2012. The drilling and equipping of two well sets each comprising 4 holes was partially completed during February and March. Preliminary evaluation of the results obtained from well site A started, using numerical ground water modeling. Five day pump test was started on well site B and a short term airlift tests was completed on this site. Further slug testing and completion of additional wells at each well site will continue into the 2nd Quarter.
Mining: Preparation work for the PFS mining study continued in anticipation of issuing the resource upgrade in Q2, 2012. Further definition of the shaft design, ventilation design, panel design and equipment selection was achieved. The impact of exclusion zones was assessed on a preliminary basis. The mining cost estimate was advanced.
Processing: Amec has revised the mass balance, process flow diagrams, 3D modeling and general layouts based on a decision to reduce the feed grade to 23.3%K2O as a consequence of mining the full upper seam. Process flow diagrams were adjusted to allow for a twin stream design. A trade off study was completed on the final plant position, considering the coastal topography and it was recommended to have the complete plant and offloading facilities on the coastal plane. This allowed the site layout to be finalized. Another trade off study was completed on various ROM storage options.
Preparation was done for the final estimating and an additional test program was initiated to conduct mineralogical characterization and liberation analysis on the US2 material.
Tailings storage facility: SRK (Perth) completed site selection of the TSF and commenced with design of the TSF site.
Infrastructure: Study work continued on the following disciplines:
All marine facilities including jetty loading facility, material
handling system, breakwater design, shipping and barging, berthing and
mooring and navigational aids.
Road alignments and trucking studies.
Brine transmission and dispersion modelling.
Water supply, power and gas supply.
Surface and employee facility design.
Aggregate supply options and strategy.
Initiated the Feasibility phase bathymetric survey and metocean studies.
Basic designs were completed and estimation is underway.
Environmental and Social Impact Assessment: The following activities have been completed as part of the environmental and social impact assessment studies, which are managed by SRK Consulting:
Submission and approval of Terms of Reference for the environmental and
social impact assessment baseline studies
Site visits for the following baseline studies:
Social and indigenous people
Natural Resource use
- Marine biodiversity
Project Management: In preparation of the estimating phase, work has proceeded on final definition of the Work Breakdown Structure, estimating methodology and economic modelling requirements.

Mineral Resource Summary - Kola Deposit of Sintoukola Project
The Sintoukola Project's Kola deposit currently contains 362 Mt
Indicated Mineral Resources and 442 Mt Inferred Mineral Resources, with
an average grade of 19.5% K2O (30.8% KCl) and 19.6% K2O (31.0% KCl) respectively, at a 15.0% K2O cut-off grade.
Within such Mineral Resources, the upper seam of the Kola deposit
contains 229 Mt Indicated Mineral Resources and 289 Mt Inferred Mineral
Resources, grading at 21.3% K2O (33.8% KCl) and 21.4% K2O (33.9% KCl) respectively, which upper seam is a higher-grade sylvinite
The upper seam has a high-grade domain containing 151 Mt Indicated
Mineral Resources and 186 Mt Inferred Mineral Resources, grading at
25.1% K2O (39.7% KCl) and 25.2% K2O (40.0% KCl) respectively, at a 20.0% K2O cut-off grade of pure sylvinite in a largely continuous mineralized
horizon. This deposit is contained within 28 km2 of the current 1,400 km2 license area and current exploration activities aim to test a much
larger area of the license to further expand resources.
