Overview

The 1,830 hectare Ahvenjarvi project area is located 30 km S-SW of the 4.7 million ounces Kittila Gold deposit owned by Agnico Eagle Mines Ltd. ("Agnico Eagle") and approximately 25 km west of Kutuvuoma.

The property was acquired by staking (Exporation Licence and Exploration Licence Reservations) following regional compilation and reconnaissance prospecting.

Access to the property is very good, with forestry roads extending from paved highways providing access to the otherwise forested and undeveloped property areas. A regional airport with daily flights to and from Helsinki is located in Kittila. Topography is low and characterized by generally rolling hills with relief of less than 150 m.

Geology and Mineralization
Bedrock geology at Ahvenjarvi is comprised of meta-sedimentary (sandstone and conglomerates) and meta-volcanic (intermediate to felsic) rock sequences of the Central Lapland Greenstone Belt (CLGB) Kumpu Group. The Kumpu Group represents the youngest geological unit in the CLGB which sits on a major stratigraphic break. The property also lies between two major regional faults with deep roots (>10-30 km).

The Ahvenjarvi property hosts a previously documented gold occurrence that was discovered by the Finnish Geological Survey (GTK) regional during regional mapping in the 1980's. Trenching and shallow RC drilling at that time outlined a 15 m wide, >125 m long, >25 m deep, E-W trending domain comprising a set of sub-parallel auriferous quartz-tourmaline-pyrite veins and breccias. The mineralization is associated with bismuth-tellurides. Best results from this historic work include 6.2 g/t Au over 3 m (trench) and 2.3 g/t Au over 3 m from RC drilling. A total of 11 RC drillholes were drilled to a maximum depth of 60 m. No other work is documented since that time.

Most economically important gold deposits of the CLGB occur in direct proximity to the metallogenically important "Sirkka Line" that is centered along the course of the Sirkka Shear zone (SSZ), a major south dipping thrust fault system showing northeast transport that has been mapped for over 120 km along an east-southeast trend within the CLGB. This shear zone is characterized by numerous sub-parallel splays that also host important, structurally focused gold mineralization. Ahvenjarvi lies 5 km south of the SSZ but is also within 3.5 km of the Venejoki Shear Zone.

2014 Exploration
Prospecting this fall has outlined a new zone of gold mineralization (named "Quinlan Zone") at the company's wholly owned Ahvenjarvi property. A total of 62 widely spaced rock samples were collected over 500 m in a north-south direction, of which 49 were from bedrock, assaying from nil to 28.3 g/t Au (grams per tonne gold). Of the 62 samples, 17 assayed >1 g/t Au, 8 assayed > 5 g/t Au and 3 assayed >15 g/t Au. The average of all samples is 2.1 g/t Au. The gold mineralization is also accompanied by elevated bismuth (Bi) and tellurium (Te).

The mineralization is comprised of a stockwork of mm to meter scale quartz-tourmaline-pyrite veins hosted by quartz-carbonate-albite altered sandstone and conglomerate within a minimum 100 m wide zone of strong potassic (sericite and k-feldspar) alteration and iron oxide (magnetite and specular hematite) mineralization.

The south end of the Quinlan zone lies 100 m east of a previously documented gold occurrence where trenching and shallow RC drilling in the 1980's outlined a similar style of mineralization over 125 m in an east-west trend. Best results from this historic work include 6.2 g/t Au over 3 m (trench) and 2.3 g/t Au over 3 m from RC drilling. A total of 11 RC drillholes were drilled to a maximum depth of 60 m.

The onset of winter prohibited further exploration beyond cursory prospecting and sampling. The zone remains wide open in all directions.

The setting, style and geochemistry of this mineralization suggest strong similarity to the "Timiskaming"-style of orogenic gold mineralization of the Timmins-Porcupine gold camp in the Abitibi greenstone belt of Ontario, i.e. gold-tellurium mineralization hosted by sedimentary rocks within a late orogenic rift basin adjacent to a major regional tectono-stratigraphic boundary

2015 Exploration
Seven trenches were excavated at Ahvenjarvi. A total of 206 individual (mostly 1m-wide) channel samples were collected from the trenches. Highlights of assay results from these trenches are presented in Table 4 below:

Further prospecting and reconnaissance mapping was conducted along and within the trend and a total of 41 rock chip (grab) samples were collected from outcrop and sub outcrop. The samples assayed up to 8.1 g/t Au, with an average for all the samples of 0.57 g/t Au. To date a total of 330 rock chip/grab, and channel samples have been collected from outcrop, sub-outcrop, angular boulders and trenches over an area measuring 2,300m long and 150m to 700m wide, with assay values up to 28.8 g/t Au and an average of all samples of 0.81 g/t Au.

The area is generally poorly exposed with the majority of samples collected within this trend occurring in a "window" through the overburden. Further work to identify new zones of mineralization and controlling structures to this widespread gold system is ongoing.
