TORONTO, ONTARIO--(Marketwired - Sept. 6, 2017) - Magna Terra Minerals Inc. ("Magna Terra" or the "Company") (TSX VENTURE:MTT) is pleased to announce the initiation of a geophysical program which covers five projects. The projects being advanced are Piedra Negra, Covadonga, El Meridiano, La Rosita and Gertrudis.
The Piedra Negra Project is located approximately 25 km N-NE of the Cerro Vanguardia gold mine (AngloGold Ashanti) and is accessible by a good unpaved road, from the Tres Cerros Hotel, 30 km to the east, (see Figure 1). The Cerro Covadonga Project, approximately 25 km north of Cerro Vanguardia, is adjacent to Piedra Negra and is accessed by the same road from Tres Cerros, approximately 40 km to the east. The EL Meridiano project is approximately 40 km NW of Cerro Vanguardia and 70 km west of Tres Cerros. These three projects constitute the first phase of the geophysical program and are to be followed immediately by the La Rosita and Gertrudis Projects. La Rosita project is located 15 km NE of Mina Martha silver mine and 21 km north of the Manantial Espejo silver mine and is approached by 80 km of unpaved roads and farm tracks from Gobernador Gregores. The Gertrudis Project is reached by 110 km of unpaved road and farm tracks from the town of Pico Truncado.
The program, covering the five projects, is comprised of 138 line km of Ground Magnetometry, 44.5 line km of Induced Polarization and 7.5 line km of CSAMT. The distribution of the work is outlined in the table below.
| Project | Technique | Mag Line km | (IP) Line km | CSAMT Line km | ||||
| Piedra Negra | Ground Magnetic | 60 | - | - | ||||
| Induced Polarization (IP) | - | 15 | - | |||||
| Covadonga | Ground Magnetic | 57 | - | - | ||||
| Induced Polarization (IP) | - | 17.5 | - | |||||
| El Meridiano | CSAMT | - | - | 7.5 | ||||
| La Rosita | Induced Polarization (IP) | - | 9 | - | ||||
| Gertrudis | Ground Magnetic | 21 | - | - | ||||
| Induced Polarization (IP) | - | 3 | - |
Our preference in this environment, which is dominated by low sulphidation veins, is to develop shallow targets with a combination of ground magnetic and IP surveys in conjunction with surface sampling and mapping. The Piedra Negra, Covadonga and Gertrudis campaigns have been planned according to this strategy.
The Piedra Negra campaign includes 12 lines of IP which are orientated east west across mostly north south striking vein outcrops and float trains. We expect the IP and magnetic surveys to confirm multiple shallow drill targets on each IP line. The types of targets identified include veins cutting andesite, veins and vein breccias cutting rhyolite domes, stockworks in rhyolite domes, and low angle veins flanking rhyolite domes.
The Covadonga campaign includes 14 lines of IP with a north easterly orientation. The IP and magnetic lines cross NNW, NW, WNW and NE striking veins and breccias which together form a dilatational jog of over a 3 km extension.
The Gertrudis campaign is comprised of 3 ENE lines of IP with an accompanying magnetic survey and are orientated perpendicular to the Gertrudis and David Veins.
In the case of El Meridiano we are using CSAMT because it is a diatreme complex rather than the more typical vein system. By using the historical geophysical data, which includes ground magnetic and gradient array data, and then adding the CSAMT, we can model the project at depth to reveal resistive targets in the diatreme flanks.
La Rosita is also atypical in the region, with gold mineralization occurring in sinters in an otherwise recessive environment. La Rosita represents a structural and stratigraphic problem which we believe can be solved by combing the historical ground magnetic and gradient array survey data with carefully placed IP lines.
The Company owns 100 % of the Gertrudis project and controls the other projects through an option agreement with a private individual.
Mr. Lew Lawrick, President & CEO of Magna Terra commented: "We are very pleased to be moving forward with this phase of our exploration program, which will bring these five projects up to a drill ready status on a level with our EL Monte project, where drill planning and budgeting is already complete. By the end of 2017 we will have six projects with drill planning and budgeting in place and we will be ready to offer these as turnkey JV projects under our management."
