Margaret Lake Property Info

• Located in the southern Slave Craton, host to two significant diamond mines: Snap Lake and Gahcho Kué (under construction)

• Property is 10km north of De Beers / Mountain Province Diamonds’ Gahcho Kué project

• Winter road to Gahcho Kué crosses the Margaret Lake property

Margaret Lake Property Option

• MLD has earned a 60% by incurring over $1mm of work expenditures prior to October 13, 2014

• An additional expenditure of $1mm by October 13th, 2015 to increase interest to 70%

• The vendor and owner of the residual 30% interest has the option, but not the obligation, to sell to MLD for $3mm

• No option payments, share consideration, or royalties payable

9

Margaret Lake Property Program

• Contracted CGG Canada to fly HeliFALCON® system which incorporates gravity and magnetics

• Over 2,800 line kilometers on 75 meter line-spacings at a nominal 45 meters above terrain

• Completed detailed property-wide bathymetry using Worldview2 high-resolution satellite imagery

• Bathymetry aided in the interpretation of gravity data and target definition a year earlier than conventional bathymetry

• 160 till samples were collected

10

Marlin Property Info

• 23 claims covering approximately 25,834 hectares, contiguous to the west of the Margaret Lake property and to the N and W of Kennady Diamonds

• 2 indicator mineral trains & untested airborne anomalies

• MLD can earn a 49% interest with expenditures of $1.75mm over 3 years

• MLD met year one obligation of $500,000

• JV agreement at 30% or 49%

Marlin Property Program

• Till sampling completed in August, 126 samples taken, sampling locations determined through re-analysis of Canterra’s proprietary database

• HeliFALCON® survey was extended to fly the original ~10,450 ha Marlin claims, over 1,500 line km flown

• Detailed property-wide bathymetry using Worldview2 high-resolution satellite imagery was completed

Satellite DTM with Bathymetry

By using Satellite Bathymetry, MLD has saved time and money compared to all previous workers.

Executive Summary

• Airborne Gravity Gradiometry (AGG) data over 23 targets was inverted

• The recovered models showed a variety of body shapes and density contrasts

• The inversion results can help with further prioritization before drilling
