The property was originally staked by Mr. Joe Leadbetter a prospector from the town of Wawa, for 3814793 Canada Inc.
Initial prospecting during 2002 and 2003 by Mr. Leadbetter consisted of following up on a previous alluvial diamond discovery near the town of Wawa in the early 1990’s. This was achieved by panning river sediment to recover diamonds and/or diamond indicator minerals and then attempting to trace the alluvial diamonds/indicator minerals back to their source rocks. The panning of river sediments by Mr. Leadbetter resulted in the discovery of two diamonds, a 1.09 and a 0.25 carat diamond, in the Magpie River, north of Wawa. Subsequent panning and prospecting by Mr. Leadbetter resulted in the recovery in December 2003, of a1.39 carat gem quality diamond from a tributary of the Magpie River in Chabanel Township.
Mr. Leadbetter then followed the tributary upstream to its headwaters and sampled the outcropping rocks there. Analysis of rock samples by caustic fusion confirmed that the rocks contained diamonds. The area at the head of the diamondiferous creek and surrounding lands was acquired and became the Leadbetter Diamond Property.
Dianor's interest
Dianor’s involvement began with a visit on the property in late summer of 2004. A letter of intent between Mr. Leadbetter and Dianor was signed in October of the same year.
The letter of intent allowed Dianor to access the property for a due diligence sampling program. This program was undertaken during the fall under the supervision of the late Dr. Winfried Brack. Bedrock samples of the diamond-bearing rock (now termed Leadbetter conglomerate) were collected from 15 locations in the northern portion of the property. Each site was excavated with a backhoe and the samples were individually bagged and sealed on-site.
From this, samples were dispatched to the Saskatchewan Research Council’s (SRC) Laboratory in Saskatoon for processing through caustic fusion to recover the diamonds contained in the rock. Four samples were also sent to CF Minerals in Kelowna, British Columbia, for attrition milling to recover both diamonds and indicator minerals. Lastly, three samples, totalling 2.7 tonnes, were sent in March 2005 to SGS – Lakefield, Ontario for commercial size diamond recovery.
December 2005
Meanwhile, the final option agreement for the acquisition of the Leadbetter Property by Dianor was signed on December 16th 2004.
March 2005
March 2nd, 2005, the Leadbetter Extension Property was optioned and consisted of 49 patented claims convering 646 hectares. The combined properties cover an area of 16 sq. km and the combined property is known as the The Leadbetter Diamond Property.
