Litchfield Minerals Limited Completes the First Phase of Drilling at Oonagalabi
Litchfield Minerals Limited announced have completed the first phase of drilling at Oonagalabi. Oonagalabi drilling confirms Broad Sulphide Mineralisation Key Highlights: 1,646m RC Drilling Program Completed. A total of six RC drill holes for 1,646 metres were completed, with holes spaced approximately 150 metres apart. Quality of assay data and laboratory tests, The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total., For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc., Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and precision have been established., Not applicable as no assay results are reported., Verification of sampling and assaying, The verification of significant intersections by either independent or alternative company personnel., The use of twinned holes., Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols., Calibration disks and OREAS reference standards were used daily to ensure reliable portable XRF analysis., Criteria, JORC Code explanation, Commentary, discuss any adjustment to assay data., Location of data points, Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation., Specification of the grid system used., Quality and adequacy of topographic control., Drill hole collars are surveyed with a handheld GPS with an accuracy of +/- 5m which is considered sufficient for drill hole location accuracy., Co-ordinates are in GDA94 datum, Zone 53., Downhole depths are in metres measured downhole from the collar location on surface., Topographic control has an accuracy of 2m based on detailed satellite imagery derived DTM or on laser altimeter data collected from aeromagnetic surveys., Data spacing and distribution, Data spacing for reporting of Exploration Results. Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied., Whether sample compositing has been applied., Drillholes were spaced approximately 150m along strike to drill parallel to pole-dipole IP lines., It is too early to establish if drillhole spacing is sufficient to establish geological continuity., 4m composite samples were completed on intervals that did not exceed 0.1% Cu or 0.1% Zn., Orientation of data in relation to geological structure, Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type., If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported, It is unknown whether the orientation of sampling achieves unbiased samples as interpretation of quantitative measurements of mineralised zones/structures has not yet been completed., The drilling is oriented perpendicular to the lithological strike. EL32279 falls within one of Geoscience Australia's IOCG high potential zones., The project lies within the Harts Range that represents a package of multiply deformed and metamorphosed sedimentary and igneous intrusive rocks., Drill hole. Information, A summary of all information material to the understanding of the exploration results including a tabulation of all information material to the exploration results including a tabulated of all information material to the understand of the exploration results including a Tabulation of all information material to all Material drill holes: easting and northing of the drill hole collar elevation or RL (Reduced Level - elevation above sea level in metres) of the drill hole collar dip and azimuth of the hole down hole length and interception depth. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not remove from the understanding of the report, the Competent, the Competent, Person should clearly explain why this is the case., Data aggregation methods, Data aggregation methods, Data aggregation method, Data aggregation methods.
