TORONTO, ON / ACCESSWIRE / October 1, 2021 / Magna Terra Minerals Inc. (the "Company" or "Magna Terra") (TSXV:MTT) is pleased to announce that it has identified several priority targets for drill testing including, an opportunity to expand on existing mineral resources at the Rattling Brook Deposit (the "Deposit") on its 100% owned Great Northern Project ("Great Northern"), located in western Newfoundland. The Rattling Brook Deposit contains a NI43-101 Inferred Mineral Resource comprising 255,000 ounces at 1.45 grams per tonne ("g/t") gold (5,460,000 tonnes) and is hosted along a 5-kilometre section of the larger Doucers Valley Fault, a similar geological environment to Marathon Gold Corporation's Valentine Gold Project. The Deposit is open for expansion at depth and along strike.
The targets were generated based on recent field programs and a comprehensive review of historic exploration data, which identified the importance of fault control on gold mineralization. Specifically, we believe that northwest and east-west striking faults, with coincident rock and soil geochemical anomalies, may act as higher-grade feeder zones to the Rattling Brook Deposit. This concept has not been previously tested and provides a unique opportunity to expand the Rattling Brook Deposit. Priority targets, as further described below include the Apsy Feeder Zone (0.6 kilometre extent), the Incinerator Trend (1.8 kilometre extent), and the Furnace Trend (1.5 kilometre extent).
Previous (1986 to 2007) select drill intercepts (core length) that partly define the Rattling Brook Deposit include:
- 1.77 g/t gold over 74.4 metres (2.3 to 76.7 metres; estimated true thickness ("TT") 60 metres), including 3.25 g/t gold over 22.7 metres in drill hole JA-05-35;
- 1.13 g/t gold over 115.7 metres (45.0 to 160.7 metres; TT 70 metres) in drill hole JA-05-36;
- 1.40 g/t gold over 84.6 metres (10.5 to 95.1 metres; TT 80 metres), including 8.62 g/t gold over 2.5 metres in drill hole JA-06-46;
- 1.28 g/t gold over 75.6 metres (1.0 to 76.6 metres; TT 70 metres) in drill hole JA-06-53;
- 3.92 g/t gold over 7.9 metres (112.6 to 120.5 metres; TT 5 metres), including 10.0 g/t gold over 1.4 metres in drill hole JA-06-60;
- 1.01 g/t gold over 66.4 metres (15.5 to 81.9 metres; TT 60 metres) in drill hole JA-07-73;
- 1.22 g/t gold over 56.5 metres (61.0 to 117.5 metres; TT 50 metres) in drill hole RB-30;
- 1.07 g/t gold over 68.0 metres (115.6 to 183.6 metres; TT 60 metres), including 8.84 g/t gold over 1.0 metres in drill hole RB-40; and
- 1.02 g/t gold over 66.5 metres (3.0 to 69.5 metres; TT 65 metres), including 7.86 g/t gold over 1.4 metres in drill hole JA-05-38.
The Company has also identified the presence of north and northeast trending fault zones that cross the 2.4-kilometre long Jacksons Arm Trend. Similar to faults crossing the Rattling Brook Deposit area, the Company believes that these faults may play an important control in focusing higher grade mineralization at Jacksons Arm.
"Based on our field work we have recognized the opportunity to further expand resources at the Rattling Brook Deposit as well as test several adjacent zones of mineralization within the immediate area. A key facet of work going forward will be to test the specific geological controls on gold where faults may play a significant role as feeder zones to broader disseminated gold within the existing mineral resource. We believe there is abundant upside to expanding the resource base at Great Northern and Viking in the near term and build upon the 255,000 ounce (5,460,000 tonnes at 1.45 g/t gold) Inferred Mineral Resource at Rattling Brook. In addition, we will continue to explore adjacent areas, including the Jackson's Arm Trend, for potential near-term discovery."

Exploration Target Details
Several drill targets and specific opportunities for mineral resource expansion and discovery have been identified by the Company based on recent field programs and a comprehensive review of historic and current exploration data. This work, in conjunction with that of previous operators on the Property, has identified the importance of fault control on gold mineralization. These major target areas for near-term drill testing are:
- The Apsy Feeder Zone - 600 metre northwest striking fault zone adjacent to and northwest of the Apsy Zone mineral resource;
- Apsy Zone - 1.0 kilometre strike length - potential up-dip extension to the Apsy Zone;
- Incinerator Trend - 1.8-kilometre long gold-bearing east-west fault;
- Furnace Trend - 1.5-kilometre long trend with rock grab samples** assaying up to 5.60 g/t gold along east-west fault zone; and
- Jacksons Arm Trend - 2.4-kilometre long gold zone cross-cut by numerous north and northeast trending fault zones.
Apsy Feeder Zone and Apsy Zone (Rattling Brook Deposit)
The Apsy Feeder Zone is hosted along a northwest oriented fault splay extending from the Apsy Zone that has a moderate south dip and has been identified by the Company and previous operators, to have a significant control on gold mineralization within the host Proterozoic Main River granites and the overlying Cambrian quartzites and phyllites. This fault is potentially associated with higher grades within the Apsy Zone. The Apsy Feeder Zone and associated fault, gold-bearing rock grab samples (assaying up to 3.2 g/t gold), and anomalous soils extends for 600 metres northwest of the Apsy Zone mineral resource and has not been tested by drilling. The most northwesterly hole drilled along this Trend, drill hole JA-05-36, intersected 1.13 g/t gold over a core length of 115.7 metres (TT 70 metres), supporting potential expansion of the Apsy Zone into the feeder fault to the northwest (Exhibit A and B).
Incinerator Trend
The Incinerator Trend comprises a 1.8-kilometre long alteration zone with numerous anomalous soils (up to 700 ppb gold) that has been successfully tested by four broad spaced (100 to 500 metres) diamond drill holes from 1987 (true thickness unknown) that returned assays of:
- 2.32 g/t gold over 4.1 metres (33.1 to 37.2 metres) in drill hole RB-41;
- 1.06 g/t gold over 15.6 metres (66.8 to 82.4 metres) in drill hole RB-39;
- 1.00 g/t gold over 9.7 metres (32.1 to 41.8 metres) in drill hole RB-37; and
- 1.78 g/t gold over 4.0 metres (47.2 to 51.2 metres) in drill hole RB-35.
The altered and mineralized zone is hosted along an east-west oriented (070o) fault zone and associated topographic low (Exhibit A, B).
Furnace Trend
The Furnace Trend comprises a 1.5-kilometre long zone of gold-bearing rock grab samples** with assays up to 5.60 g/t gold and soil samples (assays up to 66 ppb gold) that has not been tested with previous drilling. The altered and mineralized zone sub-parallel with and located 1.1 kilometres to the south of the Incinerator Trend, is hosted within a similar east-west trending fault zone (Exhibit A).
Jacksons Arm Trend
Jacksons Arm Trend is host to a 2.4 kilometre long by 40- to 400-metre-wide continuous alteration zone that is controlled by a north-south striking fault. The fault extends immediately to the north along strike with similar repeating fault zones to the east outlining a potential strike extent of an additional 4 kilometres (Exhibit A). A recent phase 1 drilling program (see news release dated February 18, 2021) by the Company at the Jacksons Arm Trend intersected broad zones of alteration and gold mineralization in each drill hole outlining a large fertile gold-bearing alteration system along at least a 300-metre section of the larger Jacksons Arm Trend with assays including:
- 4.67 g/t gold over 0.5 metres (73.5 to 74.0 metres) in drill hole JA-20-01;
- 3.84 g/t gold over 0.5 metres (46.5 to 47.0 metres) in drill hole JA-20-07; and
- 2.01 g/t gold over 1.0 metre (22.5 to 23.5 metres) in drill hole JA-20-08.
Highlights of surface grab samples** include:
- Assays up to 20.20 g/t gold and 1,232 g/t silver at the Boot N' Hammer Prospect;
- Assays up to 56.70 g/t gold and 2.75 ounce per tonne silver at the Stocker Prospect;
- Assays up to 7.20 g/t gold at the Shrik Prospect; and
- Assays up to 13.60 g/t gold at the 954 Prospect.
Several north and northeast oriented fault zones truncate the main thrust fault at Jacksons Arm in the area of multiple rock and soil gold occurrences and future work will focus on testing these fault zones for control on gold mineralization.
**Grab samples are selected samples and are not necessarily indicative of mineralization that may be hosted on the property.
About the Great Northern and Viking Projects
The Great Northern and Viking Projects comprise two separate claim blocks (13,775 hectares) that are located near the communities of Sops Arm, Pollard's Point and Jackson's Arm, Newfoundland and Labrador.
The Projects are centered along a 20-kilometre section of the Doucers Valley Fault, a significant geological control on, and host to, several gold deposits and untested prospects, including the Rattling Brook and Thor Deposits, Incinerator, Furnace, Jacksons Arm, Viking and Little Davis Pond Trends. Gold mineralization is hosted within a variety of rock types that include Precambrian or Ordovician granites, or younger volcanic and sedimentary rocks, typically along splays off the Doucers Valley Fault, a similar geological environment to Marathon Gold Corporation's Valentine Gold Project. Alteration consists of mesothermal style quartz ± iron carbonate ± sulfide veins and stockworks with 2 to 5% total sulfides consisting of pyrite, galena, chalcopyrite or sphalerite, and locally show trace amounts of visible gold.
The Great Northern and Viking Projects are host to significant Current and Historic Mineral Resources, including:
- An Inferred Mineral Resource Estimate^ of 5,460,000 tonnes at an average grade of 1.45 g/t gold containing 255,000 contained ounces at a cut-off grade of 1.0 g/t gold at the Rattling Brook Deposit; and
- An Historical Indicated Mineral Resource^^ of 937,000 tonnes at an average grade of 2.09 g/t gold containing 63,000 ounces of gold plus an Historical Inferred Mineral Resource of 350,000 tonnes at an average grade of 1.79 g/t gold containing 20,000 ounces of gold at a cut-off grade of 1.0 g/t gold at the Thor Deposit.
