VANCOUVER, Dec. 27, 2018 /CNW/ - Diamond Fields Resources Inc. (TSX-V: DFR) ("DFR" or the "Company") is pleased to announce a maiden Inferred Mineral Resource estimate ("Mineral Resource") of 1.5 million tonnes grading 22.7% Zircon (ZrSiO4) (equivalent to 15.3% ZrO2) for its Beravina project in Madagascar ("Beravina" or the "Project").
Sybrand van der Spuy, CEO, said "We are pleased to have achieved our objective of completing a NI 43-101 compliant resource statement for the Beravina Project before the end of the year. The resource statement is an important milestone in Beravina's development and clearly shows the high grade nature of the deposit. We are continuing with our work to test the market for our product and also evaluate financing options for Beravina's continued advancement."
Inferred Mineral Resource Estimate
Beravina Mineral Resource at a cut-off grade of 9% ZrO2, 14 December 2018
Category | Tonnes | ZrO2 | ZrSiO4 | HfO2 | ThO2 | U3O8 | Density |
Inferred | 1.5 | 15.3 | 22.7 | 0.3 | 537 | 46 | 3.1 |
The Mineral Resource was estimated using The Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Best Practice Guidelines and is reported in accordance with the 2014 CIM Definition Standards, which have been incorporated by reference into National Instrument 43-101 – Standards of Disclosure for Mineral Projects.
The Mineral Resource is reported at a cut-off grade of 9% ZrO2, which is the lowest grade block estimate within the mineralisation model. Given the relatively high grade of the deposit, the qualified person considers that mineralisation at this cut-off grade (of 9%) will satisfy the test for reasonable prospects for eventual economic extraction should present market conditions remain.
The zircon mineralisation occurs within a zoned quartz-feldspar pegmatite. The mineralisation is contained within the outer quartz-zircon zone that forms a roughly circular outcrop on the Beravina hill. The mineralised zone was modelled as a sheath of mineralisation with the hangingwall being towards the centre of the sheath and the footwall being the outside of the mineralised zone. The mineralised zone plunges to the north at between approximately 50° and 65° and is generally between 10m and 20m wide.
Eleven holes inclined at 50° and two vertical holes were drilled at Beravina in 2006 and 2011. These were subjected to a complete re-logging and resampling exercise by MSA in 2018. Ten of the holes intersected the mineralised zone. The drillholes are between approximately 19m and 104m long. The drillhole intersections are aligned in two horizontal lines; one on the north side and the other on the south side of the deposit.
The core samples taken by MSA were assayed at SGS Randfontein (South Africa). Samples were dried and then crushed to 80% less than 2mm. A sub-sample of 500g was pulverised to 85% less than 75µm using a carbon steel ring and puck pulveriser. ZrO2 and HfO2 were analysed using XRF with borate fusion, and ThO2 and U3O8 were analysed by ICP-MS with sodium peroxide fusion. The samples were subjected to a quality control and assurance process consisting of the laboratory's internal processes as well as the insertion of blank and certified reference material samples by MSA. The ZrO2 and HfO2 assays were confirmed within close limits by completion of check assays on a representative number of samples by a second laboratory (ALS Chemex in Vancouver).
A three-dimensional block model of the mineralised zone was created based on the drillhole logging and assays, and the mapped outcrop. The grades of ZrO2, HfO2, ThO2 and U3O8 were estimated into the block model using inverse distance squared interpolation. Density was estimated using a formula based on the estimated percentage of zircon. The Mineral Resource was classified as Inferred largely due to the low number of mineralised intersections and incomplete drill coverage of the deposit. The down-dip extent of the Mineral Resource was limited to 50m from the deepest drillhole and the mineralisation is open at depth.
The Company intends to file a full NI-43-101 Technical Report on its website http://www.diamondfields.com and SEDAR within 45 days of this announcement.
