CAPE SPENCER GOLD PROJECT
The Cape Spencer Project is an exploration stage project that has a history of past-production and the potential for near-term resource growth and discovery.
The Cape Spencer Project comprises 8 mineral claims (224 units) covering more than 5,045 hectares and is located 15 kilometres east of the City of Saint John, New Brunswick.
Project Highlights
- 5,045 hectares along 15 kilometres of strike of a regional-scale gold bearing structure - the Millican Lake Fault and associated structures (Figure 1);
- Newly expanded Project is host to large untested gold bearing alteration systems including:
- 5-kilometre alteration and gold bearing Emilio Trend with drill intercepts up to 7.86 grams per tonne (“g/t”) gold over 7.4 metres;
- Marigold Prospect with drill intercepts up to 8.71 g/t gold over 2 metres;
- Birches Zone with drill intercepts up to 5.23 g/t gold over 4.0 metres;
- The Cape Spencer Deposit has an Inferred Mineral Resource Estimate of 1,720,000 tonnes at an average grade of 2.72 g/t gold for 151,000 contained ounces in two zones:
- Northeast Zone - Inferred Mineral Resource of 740,000 tonnes at an average grade of 4.07 g/t gold, for 96,000 contained ounces at a cut-off grade of 2.5 g/t gold in a conceptual underground development; and
- Pit Zone - Inferred Mineral Resource of 990,000 tonnes at an average grade of 1.71 g/t gold, for 54,000 contained ounces at a cut-off grade of 0.5 g/t gold in a conceptual open pit.
- Hosted within similar Proterozoic-aged rocks of the Avalon Zone that host multi-million ounce gold deposits such as Haile, Ridgeway and Hope Brook; and
- Two gold deposits open along strike (Northeast and Pit Zones).

Cape Spencer Project - Cape Spencer Deposit Mineral Resource Estimate
The Inferred Mineral Resource Estimate for the Cape Spencer Deposit is 1,720,000 tonnes at an average grade of 2.72 g/t gold for 151,000 contained ounces at cut-off grade of 0.5 g/t gold and 2.5 g/t gold in two mineralized zones, the *Pit Zone and the Northeast Zone, with an effective date of January 23, 2019 (Table 1). The Northeast Zone contains a conceptual underground Inferred Mineral Resource Estimate of 740,000 tonnes at an average grade of 4.07 g/t gold for 96,000 contained ounces at a cut-off grade of 2.5 g/t gold and the *Pit Zone contains a conceptual open-pit Inferred Mineral Resource Estimate of 990,000 tonnes at an average grade of 1.71 g/t gold for 54,000 contained ounces at a cut-off grade of 0.5 g/t gold.
Table 1: Cape Spencer Project Mineral Resource Estimate – Effective Date: January 23, 2019
| Area | Cut-Off (Au g/t) | Category | Rounded Tonnes | Au (g/t) | Rounded Ounces |
|---|---|---|---|---|---|
| Northeast Zone | 2.5 | Inferred | 740,000 | 4.07 | 96,000 |
| *Pit Zone | 0.5 | Inferred | 990,000 | 1.71 | 54,000 |
| Total | 0.5 and 2.5 | Inferred | 1,720,000 | 2.72 | 151,000 |
- This Mineral Resources Estimate was prepared in accordance with NI 43-101 and the CIM Standards (2014)
- Mineral Resource tonnages have been rounded to the nearest 10,000 and ounces have been rounded to the nearest 1,000. Totals may not sum due to rounding.
- A cut-off of 2.50 g/t gold was used to estimate Mineral Resources for the Northeast Zone.
- A cut-off of 0.50 g/t gold was used to estimate Mineral Resources for the Pit Zone.
- Mineral Resources were interpolated using Ordinary Kriging from 1.5m assay composites capped at 15 g/t gold.
- An average bulk density of 2.74 g/cm3 has been applied.
- Northeast Zone Mineral Resources extend to a maximum depth of 225m below surface and are considered to reflect reasonable prospects for economic extraction in the foreseeable future using conventional underground mining methods at a gold price of CAD $1,550 per ounce.
- Pit Zone Mineral Resources extend to a maximum depth of 100m below surface and are considered to reflect reasonable prospects for economic extraction in the foreseeable future using conventional open-pit mining methods at a gold price of CAD $1,550 per ounce.
- Mineral Resources do not have demonstrated economic viability.
- This estimate of Mineral Resources may be materially affected by environmental, permitting, legal title, taxation, sociopolitical, marketing, or other relevant issues.
*The term “Pit Zone” reflects previously established deposit nomenclature that has been retained by Magna Terra. It does not denote application of an optimized pit shell or envelope for definition of Mineral Resources presented in Table 2 above.
Geology and Mineralization
The Cape Spencer Project is centered along the gold bearing Millican Lake Fault, a regional splay of the Caledonia and Cobequid Fault zones. The Property is underlain by Precambrian Millican Lake granite, and Coldbrook and Cape Spencer volcanic and sedimentary rocks. The Precambrian stratigraphy is unconformably overlain by and in fault contact with younger Carboniferous sedimentary rocks of the Lancaster Formation.
Gold mineralization at Cape Spencer is hosted within Precambrian Millican Lake granite or bounding Coldbrook and Cape Spencer volcanic and sedimentary rocks, with mineralization and alteration focussed along strongly faulted and sheared contacts between the two lithologies. Alteration consists of pervasive and patchy illite + pyrite + quartz ± iron carbonate ± sulfide veins and stockworks with 2-5% total sulfides consisting of pyrite, galena, chalcopyrite or sphalerite, and locally show trace amounts of visible gold.
There are several gold prospects that warrant additional exploration over a 15-kilometre strike outside of the Pit and Northeast Zones particularly in the eastern half of the property that will initially be a primary focus for Magna Terra.

Technical Reports and Documentation Notes
Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. All Mineral Resource Estimates were prepared in accordance with NI 43-101 and the CIM Standards (2014).
The Mineral Resource Estimate quoted in this press release regarding the Cape Spencer Project refers to the technical report: “NI 43-101 Technical Report and Mineral Resource Estimate on The Cape Spencer Gold Deposit, Saint John County, New Brunswick, Canada”, (the “Cape Spencer Report”) with an effective date of January 23, 2019, and authored by Michael Cullen, P.Geo. (Independent Qualified Person), and Matthew Harrington, P.Geo. (Independent Qualified Person).
Rock and core sample lengths from historic exploration programs that are reported in this press release are presented as core or sample lengths only. True widths of mineralized intervals are not known. All quoted drill core sample intervals, grades and production statistics were compiled from historic assessment reports obtained from either the government of New Brunswick or government of Newfoundland and Labrador that are referenced the Technical Reports noted above.
