Magna Terra identifies 2018 drill targets at Luna Roja

MAGNA TERRA REPORTS ON DATA RECOMPILATION AND NEW DRILL TARGET GENERATION AT THE LUNA ROJA PROJECT, EL MONTE PROPERTY

Magna Terra Minerals Inc. has recompiled and reanalyzed historic data including rock chips, soils, trench samples and induced polarization (IP), resulting in a refined drill plan for implementation in 2018. The Luna Roja project is located in the Santa Cruz province of Argentina, on the northern edge of the Deseado massif, approximately 75 kilometres to the northwest of the new Don Nicolas mine. The project is accessed from the town of Fitz Roy on 80 kilometres of unpaved roads and farm tracks.

The project is characterized by gold-bearing, low sulphidation breccias and veinlets which occur in structures in and around rhyolitic domes and tuffs of the Jurassic Chon Aike formation. Work carried out to date includes 360 rock chip and float samples including saw cut channels and an additional 741 trench samples, 711 of which are channel samples with the remaining 30 being selective. There are 715 soil samples and 17.6 line kilometres of IP. The position of the Luna Roja project is illustrated, relative to the El Monte property boundaries, in a figure on the company's website.

The findings discussed utilize all the aforementioned data, which are technically historical. These data were collected by AuEx Argentina SA/Renaissance Gold Inc. Note, that data described as rock chips or selective samples were taken in situations where sample spacing is determined by availability of outcrop and subcrop and so the results are not necessarily representative of the mineralization hosted on the project.

The rock chip surface sampling covers an area of two kilometres by three kilometres. Gold and silver grades range from detection up to 8.6 parts per million gold and 638 ppm silver. Average grades are 0.16 ppm Au and 11.70 ppm Ag. Mineralization on the surface is principally controlled by a 2.7-kilometre north-by-northwest-striking structure, locally called the "Via Lactea fault." At the northern end of the Via Lactea fault there is a 500-metre-by-250-metre zone of breccias, "Estrella del Norte," in a rhyolitic dome. The 68 rock chips and channel samples in this zone range from detection up to five ppm Au with an average 0.27 ppm Au. At the southern end of the structure is a zone of vein breccias in tuffs, "Cruz del Sur," where 22 rock chip samples report gold and silver grades ranging from detection up to 8.6 ppm Au and 638 ppm Ag with an average of 1.29 ppm Au and 124 ppm Ag over a strike length of 300 metres.

There are seven trenches constituting 3.6 line kilometres with an east to west configuration. Of the 741 samples taken from the trenches, 30 are selective samples and the remaining samples are saw cut and rock chip channels. Average gold is 0.041 ppm Au in the channel samples and 0.062 ppm Au in the select samples. The table illustrates the key channel sample intercepts from trenches 1 to 4.

Soil sampling and IP campaigns, carried out by Renaissance Gold Inc. in 2011 and 2012, were designed as a series of east to west lines, parallel to and in some cases adjacent to the trenches. The soil sampling results were thus calibrated to the trench channel data to extrapolate gold and trace element patterns across a wider surface area. These data were analyzed relative to the IP to define potential anomalism at depth and subsequent drill targets. A figure on the company's website illustrates gridded and contoured soil Au ppb data which constitute a range from below detection to 112 ppb, the orange to red tones representing above average Au. The image illustrates semi-continuous Au anomalism along the Via Lactea fault as well as a parallel structure 600 metres to the east. This pattern is repeated in the trace elements mercury, arsenic and antimony and to some extent in Ag data, which range from below detection to 16.4 ppm and tends to be more geographically restricted. A differernt figure on the company's website illustrates a plan composite comparing Au and Ag distribution with IP chargeability. The company observes that the precious metal anomalism skirts the principal chargeable anomaly without directly overlying it.

A different figure on the company's website illustrates chargeability IP anomalies at depth and in contact with the Via Lactea fault, forming a scenario associated with high-grade Au and Ag mineralization at surface.

It is believed that the mineralization observed is related to hydrothermal fluids which reached the surface via structures along the flanks of a largely impermeable rhyolitic dome complex and that the main IP anomaly, rather than the fault, represents the principal target. The IP anomaly constitutes a large target, possibly representing a zone where mineralizing fluids were trapped between the impermeable base of rhyolite domes and the top of a more permeable andesitic layer.

Lewis Lawrick, president and chief executive officer of Magna Terra, commented: "With an approximate 110,000-hectare land position in eight distinct district scale properties, we are systematically and methodically analyzing and compiling all historic data with a view to not only refine existing drill targets but also define new drill targets on each property in our portfolio. We are very pleased to outline our first drill-ready project in the Deseado massif. Luna Roja looks like a very large target with significant Au and Ag anomalism. Our geologists are currently planning and budgeting the initial drill campaign for execution in 2018."

Quality assurance/quality control

A QAQC program for the trench and soil campaigns included duplicates and standards with all samples placed in sealed bags and delivered by AuEx Argentina SA/Renaissance Gold Inc. staff to Andesmar in Caleta Olivia, Santa Cruz, Argentina, from where they were transported to ALS Chemex Laboratories in Mendoza, Argentina, for gold fire assay and multielement analysis.
