Mavis Lake Project

Lithium & Rare Metals

The Mavis Lake Project property consists of a package of nineteen adjacent mineral claims currently being explored by International Lithium Corp (ILC).  These include thirteen unpatented mining claims (the Mavis claims) and six patented mining leases (the Fairservice Property).

This package covers the lithium-tantalum core of the Mavis Lake Pegmatite Group adjacent to Mavis Lake near Dryden, Ontario (Fig. 1).

The Mavis Lake Project Lithium-Rare Metals Property covers 2,632 hectares within Brownridge Township and is approximately 19 km northeast of the town of Dryden on the Trans-Canada Highway in north-western Ontario.  The property is also adjacent to major rail networks.  The claims extends south and east of Mavis Lake and is bordered to the east by the Lola Lake Provincial Nature Reserve (Fig. 2).

Historical Work (pre-2009)

Current & Planned Work


During the 2011 and 2012 drilling programmes ILC both confirmed historical results and identified new pegmatite bodies. Using these new results, the next stage of work planned on the project will be detailed ground magnetic surveys. Historical work showed that magnetic lows are associated with prospective pegmatite areas. This is believed to be due to the significant contrast in magnetic properties of pegmatite and the host magic volcanics. Using the geological control established by the two drilling programmes a detailed magnetic survey is being considered to trace known pegmatites, identify new targets, and potentially locate where pegmatite bodies are widest.

2012 Drilling


 

A 19 hole drilling programme (totalling 2072.1 metres) was conducted from November 23rd to December 20th, 2012. Drilling services were supplied by C3 Drilling operating through Nacaitchewenin Development Corporation of Wabigoon, Ontario, an aboriginal owned and operated business.

2011 Drilling


A total of 20 holes (totalling 1753m) were drilled during in 2011 during August and September.  This reflected a 46% increase from the original plan of 1200m drilling motivated by encouraging results.

Results

Of the 20 holes drilled, 17 intersected one or more intervals of pegmatite greater than 2 metres and up to 78 metres in drill width.  Thirteen (13) of the 17 drill holes intersecting pegmatites greater than 2 metres width returned notable lithium grades (see table below).  Coarse grains (>5cm) of spodumene, the main lithium ore mineral, were common.  Fig. 3 shows a wide, coarse grained pegmatite intersection from drill hole MF11-12

2009 Channel Sampling


 

2009 Reconnaissance


Following the acquisition of the property in 2009, TNR Gold Corp. (the parent company of ILC) conducted a reconnaissance survey from July 25th to 26th, followed by month long channel sampling programme from September 25th to October 27th.

The initial reconnaissance survey consisted of collecting a total of 13 samples, 8 grab* and 5 channel, from Pegmatite 18 (Table 9). Assay results for lithium, tantalum, cesium and rubidium returned up to 3.14% Li2O, >122.1 ppm Ta2O5 (upper detection limit), 243 ppm Cs2O and 2500 ppm Rb2O from grab samples*. Five continuous channel samples were cut for a total length

Grab samples are by nature selective and may not be representative of the pegmatite units on the property. The assay results are presented here for geological and geochemical characterization, but the grades should not be relied upon as representative.

 

Historical Work (pre 2009)


The Mavis Lake area, including the Mavis Lake Property, has seen three main periods of mineral exploration prior to current activity by ILC:

  1. 1955 to 1964: in 1950’s lithium was the main target until tungsten and tantalum began to dominate in the 1960’s.
  2. Late 1960’s to late 1980’s: tungsten and tantalum were the focus of exploration.
  3. Early 2000 to present: the focus of exploration has been quite diversified, ranging from volcanogenic massive sulphide (VMS) copper-zinc-silver to shear-hosted lode-gold deposits.

Currently exploration efforts are once again focused on pegmatite-hosted rare metals.
