Margaret Lake Cheers as JV Partner Arctic Star Discovers New Kimberlite, “Arbutus”
Diagras Project
June 1, 2022 Vancouver, British Columbia – Margaret Lake Diamonds Inc cheers as it JV
Partner announces that its exploration team has discovered a new kimberlite that has been named
“Arbutus” on it’s Diagras project, Northwest Territories.
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.

historically into Finlay, by De Beers in the 1990’s. The black dot is the collar of the De Beers
holes, the Orange dot is the collar location of the JV’s Holes 210m distant.

About Margaret Lake Diamonds Inc.
MLD is a Canadian based mineral exploration company. As part of its joint venture with Arctic
Star Exploration, MLD holds an 18.5 per cent interest in the Diagras diamond project Northwest
Territories property. The property hosts 13 known kimberlites originally discovered by DeBeers
in the 1990’s and MLD believes there is an opportunity to apply modern exploration techniques
to define additional kimberlites. Additionally MLD owns 100% interest in the Mormon Lake
Uranium Property near Payson, Arizona.

Cautionary Statement Regarding “Forward-Looking” Information
This news release contains “forward-looking statements” including but not limited to statements
with respect to Arctic Star’s plans, the estimation of a mineral resource and the success of
exploration activities. In this release it is not certain if the kimberlite discovered will be
economic or not as this depends on many factors. Forward-looking statements, while based on
management’s best estimates and assumptions, are subject to risks and uncertainties that may
cause actual results to be materially different from those expressed or implied by such forward-
looking statements. There can be no assurance that such statements will prove to be accurate, as
actual results and future events could differ materially from those anticipated in such statements.
Factors that could affect our plans include our potential inability to raise funds as intended, and
in such event we may require all funds raised, if any, to be used for working capital rather than
the intended uses as outlined. Accordingly, readers should not place undue reliance on forward‐
looking statements. Arctic Star undertakes no obligation or responsibility to update forward‐
