Sava Lake is located approximately 27 km SW of Johnston Lake and is composed of tightly folded metasedimentary units on the NW fl ank of a large granitic dome. The lithostructural setting of the Sava Lake area is similar to that of Collins Bay-Eagle Point, but is located in a separate, parallel NE-trending structural corridor. Metasedimentary bedrock exposures are dominantly psammite with subordinate calc-silicate and pelite, and wrap around the SW end of the granitic dome. Elongate leucogranite intrusions intrude the metasedimentary sequence parallel to the structural trend.
Historic assessment reports indicate radioactive pegmatite in the area, likely related to leucogranite intrusions. Pelitic units contain graphitic horizons, which are represented by NE-trending conductors on the fl anks of the granitic dome. Several very strong lake-sediment geochemical anomalies (up to 91 ppm U) occur sparsely along 15 km of the contact between the granitic dome and overlying metasedimentary units, similar to those at Kingston Lake described above.
Numerous showings and limited historical drilling (7 DDH) focused on base metals (Denison 1969) intersected graphite- and sulfi de-rich metasedimentary horizons, but no uranium analyses or values were noted in the reporting. Further to the SW, one drill hole at "Szata Lake" intersected 80 cm of radioactive pegmatite which assayed 975 ppm U.
New airborne surveys followed by thorough lineament analysis, geological mapping, prospecting, and targeted soil sampling will be required to defi ne drill targets in this area.
