Snowfield Development Corp. ("Snowfield") has received electron microprobe analyses of 800 kimberlitic indicator mineral grains derived from till samples collected in an area centered approximately 1 km northeast of the Mud Lake diamondiferous kimberlite. This prospective area is part of Snowfield's Ticho Diamond Project, located approximately 55 kilometers southeast of Yellowknife, NWT, Canada.
Overburden Drilling Management of Nepean, Ontario recovered the till sample indicator minerals. R. L. Barnett Consulting Inc of London, Ontario undertook electron microprobe analyses of polished mineral grains. The electron microprobe work reported herein establishes the potential of this new indicator mineral source to be diamondiferous.
The latest analyses of indicator minerals as well as the results reported on August 28, 2006 (NR 06-33) were collected by a systematic sampling program over an area expanded to approximately 2000 metres by 1000 metres west of Sipper Lake. Samples were initially collected on the northern extension of the Mud Lake grid, with additional sampling performed off-grid to the north and east. These anomalous till samples form part of a new train, which is completely separate from the Mud Lake kimberlite. The Sipper Lake till samples have elevated counts of indicator minerals within the northern portion of the Mud Lake grid with counts decreasing to the west. Glacial striations indicate that the primary ice direction was from the east to west. The Mud Lake kimberlite is located to the southwest of this locale.
These till samples, counts and distribution identify a kimberlitic indicator mineral train that is 1 km wide, measured perpendicular to ice flow, and has a head that may originate near a north-trending linear underlying Sipper Lake. In order to establish a cutoff in the up-ice direction the company has carried out additional till sampling to the east of Sipper Lake where past, albeit limited, sampling had not returned indicator minerals. Till samples up-ice of Sipper Lake are currently being processed and will play a role in target selection for the upcoming winter drilling.
The latest results from electron microprobing of indicator minerals in the Sipper Lake area add to the data set of previously reported results. The latest indicator mineral analysis examined pyrope and eclogitic garnets. Similar to prior work, the pyrope garnet compositions fall within the G9 classification and extend the lherzolite trend due to their elevated chromium compositions. As was the case at Mud Lake from till sampling and core drilling analyses, eclogitic garnets are less abundant than pyrope garnets. Mineral grains from the Sipper Lake area provided seven eclogitic garnets with titanium oxide (Ti02) values from 0.10% up to 0.40% and sodium oxide (Na20) from 0.02% up to 0.08%. These eclogitic garnet compositions fall within the group 1 & 2 classifications, as was the case at Mud Lake.
Mineral compositions of pyrope and eclogitic garnets in the Sipper Lake area are markedly similar to those taken from till sampling of the Mud Lake train and from core samples of the diamondiferous Mud Lake kimberlite. The Sipper Lake area will be vigorously examined by Snowfield for new discoveries of diamond bearing kimberlite.
