International Lithium (TSXV:ILC) in conjunction with Pioneer Resources (ASX:PIO) have commenced a 1,500 meter drill program at the Mavis lithium pegmatite project in Ontario.
As quoted in the press release:

Key Highlights:

• 1,500 meter drill program commences;
• High grade spodumene Pegmatite 18 area exhibits favourable structural regime indicating potential for larger pegmatites;
• Magnetometer survey and lithogeochemical sampling program reveal pegmatite setting and new target areas; and
• Results produce highly anomalous lithium rock-sample area leading to the discovery of a new pegmatite to be drill tested during this program.

Mavis Drill Program
The majority of the exploration activities performed this year has been in preparation for this drill program.  A continuous ground magnetometer walking survey (“Mag Survey”) totalling 330 kms has been completed over the target areas of the Project. The Mag Survey successfully produced a very detailed magnetic anomaly map outlining geologic contacts, features and structures thereby providing a valuable tool to aid in the drill targeting process.  In order to refine the targets further, two campaigns of ground lithogeochemical sampling totalling 372 rock samples were collected from select locations across the Mavis Project.  The rock sample results returned areas exhibiting highly anomalous values of lithium and associated elements; key pathfinders employed as a vectoring tool for the discovery of hidden or buried pegmatites.  The anomalous lithogeochemical results overlain on the Mag Survey have provided the Company with an improved understanding of the setting of the pegmatites at Mavis; specifically the preferential horizons and structures that host them.
