Marimaca Copper Corp. Announces Results from the Phase II Drilling Campaign at the Pampa Medina Deposit
Marimaca Copper Corp. announced results from the Phase II drilling campaign at the Pampa Medina deposit, located at low altitude approximately 28km east of the Company's Marimaca Oxide Deposit ("MOD") in a flat "pampa" valley within the Atacama Desert. The information in this announcement which relates to exploration results for the Pampa Medina Project is based on, and fairly reflects, information and supporting documentation prepared by Sergio Rivera, VP Exploration of Marimaca, a Competent Person who is a member of the Comision Minera (Chilean Mining Commission), Colegio de Geologos de Chile and of the Institute of Mining Engineers of Chile. Mr. Rivera has sufficient experience that is relevant to the style of mineralisation and types of deposit under consideration and to the activity being undertaken to qualify as a Competent Person as defined in the 2012 Edition of the Joint Ore Reserves Committee Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves. The latter was initially obtained from a specific CuS test., Laboratory results are loaded directly from digital assay certificates into the database, in order to minimize error sources. The analytical quality control programs implemented at Marimaca involve the use of coarse/preparation and pulp duplicates for precision analyses and standard reference materials (SRM). Marimaca has protocols in place for handling analytical results that exceed acceptable limits, which can ultimately trigger re-assays of entire or portions of sample batches., 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., Discuss any adjustment to assay data., There are no twinned holes in the dataset, All logging data was completed, and logging data was entered directly into the deposit database., Laboratory results are loaded directly From digital assay certificates into the database to minimize error sources., 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., Local contractors carried out the supervision of the drilling operation., An experienced topographer surveyed the collars., WGS84 UTM coordinates are used., Data Well Services carried out the downhole surveys for drill holes., Data collected is considered adequate for eventual use in mineral resource estimation., Criteria, JORC Code explanation, commentary, 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., Due to the nature of mineralisation and the type of exploration discovery drilling program the hole spacing is highly variable., Data spacing is not considered sufficient to establish geological and grade continuities for Mineral Resource Estimation at the Inferred and Indicated category., No sample compositing was applied., 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 if material., Drill hole orientation was generally oriented to be sub perpendicular to the mineralisation but variable in places given the nature of the exploration program being conducted, Assays are reported on a downhole basis, True widths are estimated as 85% of reported downhole intersection widths, Sample security, The measures taken to ensure sample security., All drilling assay samples are collected by company personnel or under the direct supervision of company personnel., Samples from Marimaca were initially processed at the project site and shipped directly from the property to a laboratory facility for final preparation, and later, upon their return, to the laboratory for analysis., Appropriately qualified staff at the laboratories collect assay samples. Appropriately qualified staff at the laboratory collect assay samples. Security protocols implemented maintain the chain of samples. Security protocols implemented maintain The chain of samples to prevent unnoticed contamination or mixing of samples to prevent unnoticed contamination and to prevent unnoticed contamination or mix of samples and to make active tampering as difficult as difficult as difficult as possible.
