SHATTER LAKE 

General

 

 

The Shatter Lake Property is located in Colchester County, Nova Scotia and consists of Mineral Exploration Licence 08996 which contains 78 claim units (3120 acres or 1263 hectares). 

The Property is located within a geological environment that is favourable for the discovery of Rare Earth Element (REE) mineralization similar to nearby recent discoveries (MacHattie, 2010). Other types of mineralization such as Volcanogenic Massive Sulphide (VMS) and Iron-Oxide-Copper-Gold (IOCG) have also been reported within the Cobequid Highlands Area. 

Geology

 

 

The Shatter Lake Property is located in the eastern Cobequid Highlands and covers a 5.5 km strike length of the contact between the Byers Brook volcanic rocks and the Hart Lake-Byers Lake granite. These rock units are Late Devonian to Early Carboniferous in age. 

 

 

The Byers Brook Formation consists of a felsic volcanic sequence of rocks that has been intruded by the Hart Lake-Byers Lake (HL-BL) alkali-feldspar granite. The HL-BL granite includes mafic magmatic material and displays textures throughout indicating a shallow level of emplacement. Diabase dykes and diorite pods intrude both of these units (MacHattie, 2010). 

 

 

Mineral Potential 

 

The principal target on the Shatter Lake Property is the contact zone between the Byers Lake Composite Intrusive and the overlying Byers Brook volcanic sequence. Hydrothermal fluids generated by late phases of the HL-BL Granite have introduced REE-bearing dykes and veins into the Byers Brook volcanics. In addition, irregular bulges in the intrusive/volcanic contact zone may have focused these mineralized fluids resulting in REE-bearing pegmatite phases within the upper part of the intrusive body. The geological setting also includes the proximity to a major regional fault structure – the Cobequid-Chedabucto Fault Zone – which passes immediately to the south of the Property. This geological environment is similar to many other parts of the world where REE deposits have been discovered.

Summary of 2010/11 Work Program

Johnson Lake Area

 

The Johnson Lake District is located in a mafic-felsic volcanic and plutonic suite of rocks in the Cobequid highlands. Recent discoveries of anomalous REE indicator minerals (Th, Zr, Y, Nb) in such rocks as well as the increasing potential for Iron-Oxide-Copper-Gold (IOCG) type discoveries along the Cobequid-Chedabucto Fault Zone make the Johnson Lake District a strong candidate for discovery of either type of deposit.

The 2010 work program focused on establishing access to the properties, completing an orientation Scintilometer survey and a XRF geochemical survey. In total 36 scintilometer survey stations were established while XRF data was collect at 33 stations. Samples were also collected at XRF stations for more thorough XRF analysis. Scintillometer results have begun to outline a total counts per second anomaly southwest of Johnson Lake.

Preliminary XRF data was used to produce grids to identify regions of anomalous indicator mineral concentrations for rare earth element indicators as well as Iron-Oxide- Copper-Gold indicators. Preliminary grids have outlined elevated REE values in the NE area of the Johnson Lake properties, while IOCG indicator grids have begun to outline elevated values in the NW area of the properties.

Additional work completed was a compilation of topographical, geological and forestry road network maps, available from NSDNR’s digital database. Various maps were overlain to establish differences in mapped geology, as well as a plan of access to the property. Maps were then checked for validity in the field. Geological maps proved to be accurate in some areas while other areas needed revisions. Forestry network roads proved to be the most inaccurate maps available from NSDNR. Part of the work focused on crews generating our own as-built road map of the property.

Summary- Silica Mountain Area

 

The 2010 work program included reconnaissance and follow up field work based on information garnered from Gulf Minerals Canada Ltd. work in the later part of the 1970’s. The central focus of the 2010 program was to collect data via a handheld portable XRF analyzer. The data was then used to produce grids to identify regions of anomalous indicator mineral concentrations (REE and IOCG) for further exploration.

Field results were promising, and several locations of anomalous REE and IOCG indicator concentrations were identified. Additional field discoveries included observation of widespread sulfide mineralization, generally elevated Scintilometer readings (total counts per second) and the identification of a possible marker horizon in the Byers Brook Formation. 

 


Overview

The NSU Resources property being described here relates to ground that is highly prospective for REE’s, in the same rock formations/geological environment (BBF and HLBL) that have recently been identified by the Nova Scotia Department of Natural Resources (NSDNR) as containing REE’s (MacHattie).  In the fall of 2009, the Nova Scotia Department of Natural Resources (NSDNR) geologist Dr. Trevor MacHattie issued a report titled “Magmatism, Alteration and Polymetallic Mineralization in Late Devonian to Early Carboniferous Felsic Volcanic and Plutonic Rocks of the Eastern Cobequid Highlands.” MacHattie, Report on Activities 2009. NSDNR geologist Dr. MacHattie also produced the PowerPoint Presentation “TrevorAGS_2011”, and Poster “Trevor_GM2010_poster”. Both these documents describe some of the findings in the Debert Lake area.

Some of Dr. MacHattie’s Regional data shows a Yttrium (REE indicator) Anomaly between Shatter Lake and Irvine Lake, which is directly on NSU Licence 08996. There is also a significant Thorium Anomaly south of Johnson Lake that straddles NSU Resources Licence 08996 & Clear Lake Resources Licence 08997.

Very preliminary research at the NSDNR Library and 2010 first pass Prospecting has confirmed these anomalies relating to REE’s within the NSU Resources claims group that show a regional east/west trend (Map 2). All of Dr. Trevor MacHattie’s work is public information that can be obtained from NSDNR.
