Maritime’s Whisker Valley gold exploration project is located within 10 kilometers and to the northwest of the Company’s Hammerdown Gold Project. With the acquisition of 192 new claim units covering 4,800 hectares in 2019 Maritime’s current land holdings at Whisker Valley 610 claim units covering 15,250 hectares. The property is easily accessible from a series of forest access roads connected to the Baie Verte highway (HWY 410) located at the property’s western boundary.
Geology, Structure and Mineralization
The property occurs within a major tectono-stratigraphic zone in the northeastern portion of the Appalachian orogeny of eastern North America. It is bounded by two major fault systems, the Baie Verte Fault Line to the west and the Green Bay Fault to the east. The Baie Verte Fault Line is a crustal-scale north-northeast striking fault system that separates obducted ophiolitic crust and underlying mantle from the Laurentian continental margin (Humber Zone) to the west with the diverse oceanic rocks of the Dunnage Zone of central Newfoundland to the east. Hydrothermal systems active during the Silurian Taconic orogeny are thought to be responsible for the deposition of epigenetic lode gold deposits in this region. Maritime recognizes the importance of these large-scale regional structures as conduits for the localization and transport of mineralizing fluids and secondary splay structures as the depositional environments for gold.
Two mineralized corridors define the abundance of gold mineralization discovered to date on the Whisker Valley property, 1.) the Whisker Valley Trend and 2.) the Middle Arm Fault Trend. The Whisker Valley mineralized corridor occurs within a north-south trending erosional window exposing Burlington Granodiorite between rhyolitic and felsic tuffaceous units of the younger King’s Point Volcanic Complex to the east and west. A significant number of gold bearing quartz veins and abundant mineralized float have been discovered along this north south corridor covering an area 3 km north-south by 1.5 kilometers east-west. It is believed that the mineralized corridor continues further to the north and south along the exposed Burlington Granodiorite window.
Whisker Valley Trend
Within the favourable Burlington Granodiorite window, the Company has uncovered a zone of extensive outcropping of gold-bearing quartz veins referred to as the Gary Vein System. Currently the Gary Vein System is the most significant gold discovery on the property and is a strong indication of potential for additional gold mineralization nearby. Trenching to date has exposed a prominent east-west trending vein system extending 320 meters and it remains open in both directions. Historical drilling and 4 drill holes completed by Maritime in 2018 have tested the vein system to a vertical depth of 70 meters beneath the trenched area and it remains open at depth (Table 1). Several stacked quartz veins define the Gary Vein system along much of the 320 m long trenched area, with individual vein widths averaging between 0.3 and 1.0 meters. Total sulfide content varies between 10 and 30% and is dominated by pyrite with locally abundant chalcopyrite, galena and sphalerite. Systematic channel sampling along the Gary Vein trench have demonstrated continuity of significant gold mineralization along its 320 meter exposed length and over potentially mineable widths. Visible gold has been discovered in numerous locations along the trenched area.

In 2019, Maritime’s exploration team successfully identified a significant new mineralized boulder field located approximately 1.2 kilometers east of the exposed Gary Vein system. A total of thirty (30) angular float samples returning assays between 1.0 and 83.8 g/t gold (average 15.45 g/t) were collected in this area and closely resemble Gary vein-style mineralization. Based on the angularity of the float samples, it is believed that the original source of the samples is close by. Being locally derived, this discovery represents the potential for a proximal gold rich vein system.
The epigenetic gold-bearing quartz veins at Whisker Valley are of similar style to the gold bearing veins at the Hammerdown deposit. The east-west trend of the Gary quartz vein system and other veins identified along the Whisker Valley mineralized corridor are identical to the trend of the strongest gold vein development at Hammerdown and represents a new target direction to explore for gold deposits in this region.
Middle Arm Fault Trend
The Middle Arm Fault mineralized corridor forms a roughly 10 km long by 1 km wide northeast trending curvilinear belt extending northeastward from the west-central part of the property at Micmac Lake (Figure 3). The Micmac-Flatwater Fault and Middle Arm Fault appear to define the northwest boundary of the mineralized corridor. Historical exploration has identified significant gold mineralization along this trend with the majority of this work being focused along the eastern side of Micmac Lake. Abundant gold bearing quartz-sulfide veins, high grade mineralized float and significant coincident gold-in-soil and geophysical anomalies occur in this area.
In 2019, Maritime completed an extensive soil sampling program which resulted in the discovery of a 1.6 km long by 0.4 km wide gold-in-soil anomaly located south of Struggler’s Pond and within the Middle Arm Fault mineralized corridor. A trenching program was carried out to locate the bedrock source of the gold-in-soil anomaly. Trench 12, located at the western end of the soil anomaly, was successful in exposing a portion of the Middle Arm fault comprising of brecciated granodiorite and pyritized quartz veins at this location. Channel sampling across the zone retuned 2.27 g/t Au over 3.1 meters.
Gold mineralization discovered to date along the Micmac-Middle Arm Fault mineralized corridor occurs within north-northeast trending quartz-sulfide veins and associated brecciated zones hosted by mafic volcanic units of the Micmac Lake Group and by the Burlington Granodiorite. Historical drilling in the Micmac Lake area discovered several gold zones. One of the historical holes intersected a quartz vein with 14.23 g/t gold over 1.2m and then 3.15 g/t Au over 3.2 m within a mafic dominated breccia zone containing pyrite, galena, sphalerite and chalcopyrite mineralization. Both these intersections are within a 2.4-meter core length of each other and are separated by a mafic dyke. This zone is open in all directions and has only seen one drill hole to date.
The Whisker Valley Property exhibits significant gold discovery potential. Maritime has a drilling and trenching dominated exploration program planned for 2020, focusing on the Gary Vein system, the significant number of under-explored gold targets identified to date on the property and outward exploration to locate new gold targets.
