TORONTO, ONTARIO--(Marketwired - March 1, 2018) - Magna Terra Minerals Inc. ("Magna Terra" or the "Company") (TSX VENTURE:MTT) (SSE:MTTCL) is pleased to provide an update on its exploration activities in Santa Cruz Province, Argentina. Our main activities concentrated on generating drill targets from geophysical surveys carried out during 2017.
The geophysical program, included 21-line kms of ground magnetometry, 3-line kms of induced polarization (IP) at Gertrudis, and 7.5-line kms of CSAMT at El Meridiano.
Analysis of all new data at El Meridiano and Gertrudis is complete, and these projects will now join Luna Roja, Piedra Negra, Covadonga in the drill ready category.
Exploration activity has also continued during the first quarter of 2018 on our 24 properties, within eight distinct land packages totaling over 100,000 hectares, in mining friendly Santa Cruz Province. Additionally, we continued with prospecting activities on our Boleadora Group of properties, which constitute approximately 50,000 hectares in the north-western corner of the prolific Deseado Massif, and proximal to Goldcorp's Cerro Negro Mine.
El Meridiano is located approximately 37 km north-west of the Cerro Vanguardia gold mine (Anglo-Ashanti) (see Figure 1). The property lies in the western part of an 8-10 km wide caldera, and the westernmost part of this feature is thought to be the site of a 2.5 km wide diatreme complex. Andesitic to felsic tuffs in a 4 sq. km area are cut by gold-bearing hydrothermal breccias filling N to NW trending fractures and faults.
Historical work, carried out by AuEx Ventures/Renaissance Gold, between 2008 and 2011 included surface rock chip sampling. A total of 319 samples were taken with an average of 0.36 ppm gold and with almost half (175 total samples) containing at least 0.1 ppm Au to a maximum of 8.9 ppm Au. The samples are anomalous in arsenic, antimony and mercury, the three most common gold pathfinder elements. AuEx also carried out 65 line-km of magnetic and 32.5 line-km of gradient array IP ground surveys and completed 32 drill holes totaling 4,698 m in two reverse circulation campaigns and one diamond core twin-hole campaign. The drill holes were collared within a 1 sq. km area in the northwestern-most part of the property. Most of the holes intersected one or multiple intervals of anomalous gold, and 10 holes intersected at least 0.14 ppm Au over true widths ranging from 1.5 to 13.5 m.
The recent CSAMT survey constituted 7.5 line-km in 3 lines with N-W orientation. The central of the 3 lines is illustrated in Figure 2, which shows a large triangular zone of resistivity which underlies a structurally controlled recessive zone in which most of the surface mineralization and historic drilling occurs. Using a combination of the historic data and the CSAMT, the Company has devised a 2000 m drill program, comprising 5 proposed holes with the intention of testing the interface between the resistive anomaly and the principal NE striking structures as well as the paleosurface.
Gertrudis is in the north-central part of the Deseado Massif, approximately 100 km to the NW of the Don Nicolas Mine and 150 km east of Cerro Negro (Goldcorp).
The Gertrudis project comprises two mineralized structures, the Gertrudis and David veins. These veins are some 300m apart, sub parallel and steeply dipping to the W-SW. Historically, sampling was carried out by AuEx/Renaissance Gold with an average from 109 samples on the Gertrudis and David Veins of 35 ppb Au. The Au is accompanied with averages of 133 ppm As and 31 ppm Pb. The recent ground magnetic and IP surveys at Gertrudis constituted 21 line-km and 3 line-Km respectively. Figure 3 illustrates surface gold anomalies relative to reduced to the pole ground magnetic data where magnetic low anomalies occur in association with and parallel to the N-NW striking mineralized structures. There are also W-NW trending magnetic lows. Figure 4 illustrates the Induced Polarization resistivity at 90 m depth which also implies a N-NW and W-NW control.
Using a combination of the historic assay data and the new IP and magnetic data, the company has devised a 2000 m drill program, designed to test the resistive IP anomalies and magnetic lows associated with the gold bearing structures.
Note that surface samples described on these projects are selected samples, with spacing being determined by availability of outcrop and sub-crop and are not necessarily representative of the mineralization hosted on the property. The QAQC programs for the drill campaigns included duplicates, blanks and standards with all samples placed in sealed bags and delivered on site, in the case of the two reverse circulation programs, to Alex Stewart staff who transported the samples to their Laboratory in Mendoza, Argentina, for sample preparation and gold fire assay and multi element analysis. Samples from diamond drilling campaign were cut on site and delivered to ALS Chemex Laboratories in Mendoza, Argentina, for gold fire assay and multi element analysis.
The Company now has five projects that are drill ready; being Luna Roja, Piedra Negra, Covadonga, EL Meridiano and Gertrudis. These projects are available for option or joint venture and the Company is actively presenting them to prospective partners, with a view to having one or more of them under partnership and moving forward through phase one drilling in 2018.
