Cache Exploration Properties
1. Welsford REE Properties
The Welsford REE Properties consist of the Outer Welsford REE Property on 124 claims that cover most of the Welsford Peralkaline Intrusion and the additional 6 claims referred to as the Inner Welsford REE Property. Combined, this grants Cache control over the entire Intrusive Complex.
The Welsford Intrusive Complex is 20km north of Saint John, N.B. Historic geological mapping and sampling by Uranerz Exploration Ltd. for uranium in 1980, which was followed by trenching and drilling in the early 2000's has revealed significant Zr-Nb-Y-REE-Ta mineralization hosted within a peralkalic pegmatite-aplite dyke swarm that intruded the Welsford Peralkaline Intrusion. Petrogeochemical studies (Seidlier, 2003; Seidler et al., 2005) have reported up to 31,285 ppm Zr, 3,040 ppm Nb, 2,021 ppm Y, 2,281 ppm Ce, 500 ppm Nd, 99.9 ppm Sm, 42 ppm Tb, 284 ppm Yb, 45 ppm Lu, and 220 ppm Ta from 7 random surface grab samples selected from trench exposures taken at one of the McKeel Lake peralkalic dykes, which will be a priority exploration and drill target on these claims. Grab samples can be selective in nature and may not reflect the average grade on the property. These high values represent concentrations comparable to those found in the richest heavy REE deposits in the world. In the fall of 2009, Dr. David Lentz, Economic Geology Chair at the University of New Brunswick (now Director for Cache Exploration), coordinated and oversaw the surficial B horizon soil sampling and analytical program over the Welsford property; the instrumental neutron activation analytical results of this program revealed many highly anomalous soil samples with high Lanthanum (La), Cerium (Ce) and Neodymium (Nd), followed by Samarium (Sm), Europium (Eu), Terbium (Tb), Ytterbium (Yb) and Tantalum (Ta).
2. Louil Hills REE Property
Location and Access
The Louil Hills property is located on the Bonavista Peninsula, eastern Newfoundland, situated on an eastern extremity near Musgravetown, with Bunyan’s cove to the west (see Fig’s 1 and 2). Route 233, a paved road, crosses the property and access around the grounds is provided by logging roads and trails. A small airstrip, power lines, and water supply are in close proximity. The industrial, commercial and government centre of Clarenville, a seaport, is 30 km south.
Geology and Previous Work
The property sits on the BullArm Formation, a suite of subaerial mafic and peralkalic felsic lava and pyroclastic rocks, which is related to (by similar trace-element character) the subvolcanic Louil Hills peralkaline granite (O’Brien et al., 1988; see Figs. 1 & 3). Detailed geological mapping, sampling, geochemical, and geophysical surveys and drilling were completed by Cornerstone Resources Inc. (Hutchings, 1998). They have revealed Zr-Nb-Y mineralization, as well as Cu and Pb mineralization hosted within felsic volcanic rocks and mafic dykes. The BullArm Formation has presented 570 ppm Y and 490 ppm Nb (Miller, 1989), making it a highly favourable exploration target, relative to other REE targets in Newfoundland.
Copper occurrences lie on the eastern portion of Cache Exploration Inc. claims, where historic samples have very significant shown 21.1% Cu, 1194 ppb Au, and 3.02 oz/t Ag; alkalic gold-rich porphyry copper deposits with high REE are not uncommon.
2010 Exploration Work
The presence of Zr-Nb-Y mineralization within the same suite of peralkalic felsic and mafic volcanic rocks (shoreline location) indicates potential for the same mineralization on Cache Exploration Inc.’s property. Cache Exploration is anticipating a preliminary scintillometer prospecting and geological reconnaissance program over the entire Louil Hills property.
3. Cross Hills REE Property
Location and Access
The Cross Hills property (63 claims) is located in southeastern Newfoundland, about 1.5km north of Grand Le Pierre, within the Cross Hills Intrusive Complex (see Figs. 1 and 2). Access to the property is through the English Harbour Road (Rte 211), which runs adjacent to and through Cache Exploration claims. Cache Exploration claims are close to all infrastructures needed to mine and process this specific style of mineralization, in a province known to support mining.
Geology and Previous Work
The claims are situated within the Cross Hills Complex, where a group of related gabbro to diabase, grandiorite, biotite granite, peralkaline and minor syenite outcrops over 260 km2. Detailed geological mapping, sampling, and petrographic studies were completed by Tuach Geological Consultants Inc. (presented in 1984) over a 20km2 area to the northwest of Grand Le Pierre. They revealed that the peralkaline granite and immediately adjacent rocks are host to numerous mineral occurrences (see Fig 3). The most significant was the discovery of Zr-Nb-Y-REE mineralization hosted in small aplite dykes (and veins) that intrude the peralkaline granite.
Cache Exploration Inc holds claims that are immediately adjacent to known Zr-Nb-Y-REE mineralization (Tuach, 1984). The south end of Cache Exploration’s property runs almost parallel to the contact between the mafic volcanic unit and the peralkaline granite, and is crosscut by faults. Numerous peralkaline and biotite granite veins and dykes intrude the mafic unit, notably adjacent to the faults. Similar biotite granite intrusions, adjacent to the same fault that cross cuts the Cache Exploration property, were sampled due to high radioactivity and revealed 6328 g/t Zr and 316 g/t Nb (Tuach, 1984), indicative of underlying mineralization.
2010 Exploration Work
The presence of the same suite of peralkaline granite dykes and veins (as noted above) located on Cache Exploration Inc. claims points to other potential areas for such mineralization (Miller, 1990). Cache Exploration is anticipating a preliminary scintillometer prospecting and geological reconnaissance program over the entire Cross Hills property.
4. Bluff Lake Cu-Au Property
100 Mile House, British Columbia
Cache Exploration has an Option to earn a 70% interest in the Bluff Lake Cu-Au Property. The Bluff Lake Cu-Au property lies within the mineral rich Quesnel Trough just north of GWR Resource's Lac La Hache property where several significant copper-gold deposits are being actively explored.
Exploration targets identified from analysis of airborne geophysical data were tested by soil geochemistry. A distinct copper anomalous area was further sampled and drill tested in 2008. Sampling was conducted using accepted QA/QC protocols and all analytical work was conducted by Assayers Canada - a reputable and ISO 9001 certified laboratory.
The most recent exploration resulted in the discovery of metallic copper mineralization in bedrock and substantial amounts of chalcopyrite and bornite in glacially transported float. Copper mineralization was intersected by drilling of four holes spaced over a 500 metre length and is considered open to the east, north and to depth. The metallic copper mineralization intersected by drilling and the copper sulphide rich float discoveries present worthy exploration targets. Although distinctly different it is not inconceivable that the two styles of mineralization may be spatially and/or genetically related. Glacial till obscured areas ranging from north to east of the current exploration work are considered to be among the primary exploration vectors.
Future work should further delineate the 2008 bedrock copper mineralization and also explore the "up-ice" vectors (north to east) to search for the source(s) of the high-grade copper bearing float.
To accomplish these goals the potential exploration techniques include geochemical sampling (Mobile Metal Ion) which has met with considerable success on the adjacent Lac La Hache property along with Induced Polarization surveys and diamond drilling.
