Arctic Star Discovers New Kimberlite, “Arbutus” at Diagras Project, NT

1 June 2022

One June 1, Arctic Star Exploration Corp. (TSXV:ADD) (Frankfurt:82A2) (WKN:A2DFY5) (OTC:ASDZF) announced their exploration team has discovered a new kimberlite that has been named “Arbutus” on it’s Diagras project, Northwest Territories.

An example of the Coherent kimberlite recovered from drilling the Arbutus Kimberlite, note the Chrome Diopside (Green) and Garnet (Burgundy Red) prominent indicator minerals, with abundant coarse olivine in a dark matrix.

Ground Magnetics shows the anomaly of Finlay, dark blue and Arbutus a magnetic low SE of Finlay (also dark Blue).

The discovery was made by testing a Class B type kimberlite target from wide helicopter supported EM survey on the Diagras project and from ground geophysical follow-up. The Class “B” targets are the 25 known kimberlites on the property. The historic exploration tended to assume these kimberlites were classic single event, vertical, “carrot shaped” pipe like bodies as dictated by the kimberlite model. However, experience in the Lac de Gras kimberlite field, (an 80km by 120km ellipse containing >200 kimberlites of similar age), has demonstrated that many of the kimberlites are not single, but multiple eruptive events with multiple lobes forming complexes, with complex shapes. The Class B style target has been the focus of our exploration to date and in 2021 it led to the discovery of 5 new kimberlites, including Sequoia, confirming the concept.

In this case the Arbutus kimberlite was discovered by drilling a distinct magnetic low SE of the known Finlay Kimberlite. Early description of the kimberlite is that it is a Coherent kimberlite with coarse sub centimeter olivines and abundant diamond and mantle indicator minerals and example of which is shown in Figure 2. From the drill intercepts and geophysics the pipe appears about 200m long and 25m wide.

Drill hole DG2022-08 was drilled at a dip of minus 50° and a bearing of 60°, DG2022-09 was drilled from the same collar and bearing at a 70° dip.

About Arctic Star

Arctic Star is predominantly a diamond explorer, recently discovering 6 new kimberlites in the prolific Lac De Gras kimberlite field that supports 2 multi-billion dollar kimberlite mining complexes. The Company also has a 958 Ha Exploration permit containing several diamond-bearing kimberlites on its Timantti project, Kuusamo Finland. Arctic Star has optioned its Stein diamond project in Nunavut to GGL diamonds who plans to work once Covid restrictions lift. The Company continues to look for appropriate diamond opportunities elsewhere.

The Diagras project is a joint venture between Arctic Star Exploration Corp. (currently 81.5%) and Margaret Lake Diamonds Inc. (currently 18.5%).
