Peregrine Diamonds Ltd. reports the discovery of the CH-17 kimberlite on the Chidliak project on Baffin Island, Nunavut, Canada. The discovery of CH-17, 35 kilometres north of the nearest known kimberlites, CH-6 and CH-10, is further confirmation that Chidliak is a highly prospective and large Canadian diamond district. Formerly geophysical anomaly 166, CH-17 is the northernmost of two high-priority magnetic anomalies, 165 and 166, that have similar geophysical characteristics and are situated 200 metres apart under the same lake. Each of the anomalies has estimated surface expressions of at least one hectare. With this discovery, Peregrine management is confident that anomaly 165 is likely also a kimberlite.
The CH-17 drill core was described in the field as being macrocrystic olivine-rich kimberlite, containing country rock and mantle xenoliths, and abundant kimberlite indicator minerals. Pyrope garnet and chrome diopside grains up to 30 and 15 mm in size, respectively, were observed.
The CH-17 kimberlite is the first target drilled this year and the seventeenth kimberlite discovered at Chidliak since 2008. The discovery was made by drilling a vertical core hole from lake-ice into the centre of the high-priority magnetic anomaly and kimberlite was intersected underneath 41 metres of water and 2.5 metres of overburden. Three metres of kimberlite drill core was recovered before the hole was terminated due to drilling difficulties. A map showing CH-17 and the adjacent anomaly 165, and photographs of drill core, are available at: http://www.pdiam.com/i/pdf/chidliak613.pdf.
A second hole was not immediately attempted at CH-17 to allow for a thorough review and analysis of the drilling issues by Peregrine and the drilling contractor. While awaiting delivery of drill supplies, a geophysical anomaly 1.6 kilometres north of CH-17 was drilled because of its proximity to a favourable kimberlitic indicator mineral train. No kimberlite was intersected and the anomaly was explained by magnetic gabbro. The indicator mineral train is now interpreted as having likely originated from CH-17 and anomaly 165.
Since the CH-17 discovery hole was terminated on May 3, there have been ten days where weather did not allow access to the drill because of low visibility and/or high winds and blowing snow. In addition, unseasonably warm local weather has led to the formation of slush on the lake hosting CH-17 and anomaly 165. Both CH-17 and anomaly 165 cannot be efficiently drilled from the lake shore. For safety reasons, after a comprehensive analysis by an independent ice engineer, Peregrine has decided to postpone further drilling on the lake-ice at this particular locality until the spring of 2011. The drill is currently being moved to test two additional lake-based targets, anomalies 290 and 291 (see map at link noted above), that have more favourable lake-ice drilling conditions, and drilling is likely to commence in the next few days. Up to 30 land-based kimberlite targets are expected to be drilled this year during the spring and summer programmes at Chidliak.
Discoveries of high concentrations of kimberlitic indicator minerals (“KIMs”) on the 980,000 hectare Chidliak property in 2006 and 2007 encouraged Peregrine to look for new kimberlite deposits in the area due to the excellent potential for further diamond discovery. The property is located 150 km northeast of Iqaluit, capital of Nunavut. Three distinct and well-defined KIM anomalies situated 20 to 30 km apart were identified. Peregrine collected a total of 970 till samples at Chidliak in 2006 and 2007, of which 286 samples, or 29 percent, contained KIMs. The full suite of KIMs have been recovered from the property, including p-type pyrope garnet, eclogitic garnet, chrome diopside, picroilmenite, chromite and forsteritic olivine. A significant number of the KIMs were over 1.00 mm in size. Kimberlite mineral grains larger than 1.00 mm are not common and are often a strong indication of a proximal kimberlite source. Ten percent of the 2,284 p-type pyrope garnets that were analyzed by electron microprobe are classified as high-chrome, low-calcium G10 garnets. G10 garnets are commonly associated with diamond mines throughout the world. Based on the favorable indicator mineral results, a heliborne magnetic/electromagnetic survey commenced in July, 2008, the survey, flown at 100 metre line spacing, was completed in August.
The CH-1 kimberlite was discovered when a kimberlite outcrop within a circular magnetic anomaly selected from an airborne geophysical survey was identified.
Northern Shield Resources Inc. The Wabassi and Max properties are located in northwestern Ontario, 60 km south of the Highbank Lake project and 100 km south of the Ring of Fire Ni-Cu-PGE and Chromite deposits. The properties are being explored for reef-hosted PGE and massive sulphide Ni-Cu-PGE deposits.
The Wabassi and Wabassi North properties were staked by Northern Shield Resources Inc. in 2007 based on the geophysical pattern observed on the magnetic survey published by the Ontario Geological Survey (OGS) in the Fort Hope area, which suggests a layered intrusion. Now four mafic-ultramafic intrusions are known to exist within the two properties.
WABASSI LAYERED INTRUSION
This is a layered mafic-ultramafic intrusion composed of olivine-gabbronorites and norites in the upper (northern) portion. To date, very little exploration has been conducted on the southern portion but it is now believed to represent the lower, and most prospective, levels of the intrusion.
WABASSI LAYERED INTRUSION
This is a layered mafic-ultramafic intrusion composed of olivine-gabbronorites and norites in the upper (northern) portion. To date, very little exploration has been conducted on the southern portion but it is now believed to represent the lower, and most prospective, levels of the intrusion.
WABASSI NORTH INTRUSION
Other than one drill hole, no other exploration has been conducted to date on the Wabassi North Property. Drilling intersected a variety of gabbroic rocks which may, or may not be related to the main Wabassi layered intrusion or the Max peridotite intrusion. The geophysics suggest that this body may consist of composite phases of gabbroic and other mafic/ultramafic phases.
MAX PERIDOTITE INTRUSION
Five drill-holes were completed on this target by Northern Shield in 2007 as part of an option agreement to earn a 50% interest in the property. The body is composed mostly of peridotite (harzburgite) and comprises the most primitive rocks intersected to date within the two properties. The body has high background levels of Ni-Cu-PGE. Geophysics suggests a possible feeder conduit between the Max peridotite and Wabassi North gabbro.
GABBROIC INTRUSION
An intrusion in the southern portion of the Max property (see figure above) has been mapped by the OGS as a gabbroic body, but no exploration has taken place to date on this portion of the Property.
WABASSI LAYERED INTRUSION
The Wabassi intrusion is a well-layered mafic-ultramafic complex with similarities to the Stillwater Complex in Montana, where PGEs are mined from the J-M reef. Rock-types so far identified include, olivine gabbronorites, olivine norites and norites; these are all ideal lithologies in nickel and PGE bearing systems. The intrusion is being explored for Ni-Cu-PGE massive sulphides along the contacts and in feeders, and for disseminated mineralization hosted in “reefs”.
Based on geophysical interpretations and surface sampling, the Wabassi layered intrusion appears to be composed of two districts series, the Cyclic Series and the Layered Series.
Ongoing studies and interpretation of the Wabassi intrusion have isolated two layered sequences that will also be prospected for disseminated reef-type PGE mineralization and chromite. Disseminated mineralization and chromite are not usually detected by airborne EM surveys.
A VTEM survey completed over the Wabassi property has detected three distinct clusters of electromagnetic (EM) anomalies (WAbassi A, B & C.) The strength of the conductors range from moderate to very strong and correspond to magnetic highs. One of the clusters of VTEM anomalies can be traced intermittently along a magnetic feature that has strike length of 2000 meters. The location and geometry of this body suggests it may represent a feeder conduit into the main Wabassi Intrusion. Feeder conduits are ideal hosts for Ni-Cu-(PGE) mineralization. Fragments of nickel-bearing pyrrhotite and blebs of primary nickel-copper mineralization were observed in core from a drill-hole completed in 2008 adjacent to one of the VTEM conductors.

Apollo Minerals (Australia), an iron ore explorer and developer, has reported on exploration progress at its Mt Oscar Magnetite Project in the Pilbara Province of Western Australia, during the quarter.
An exploration target of 350 to 650 million tonnes grading 30% to 37% in situ iron was modelled for Apollo’s Mt Oscar Magnetite Project. Metallurgical tests demonstrated >60% iron concentrate grades are achievable.
In addition to undertaking initial metallurgical testwork and commencing a detailed geological mapping program at Mt Oscar, the volume/tonnage modelled from aeromagnetic data was upgraded in light of the better than expected apparent thicknesses of magnetite-bearing banded iron formation (BIF) encountered in recent drilling.
Exploration Target
Detailed forward and 3D magnetic models, generated in 2009 by independent geophysical consultants Southern Geoscience Consultants (SGC) from airborne magnetic data flown by Apollo over its Mt Oscar project area, have been revised to take account of the results of the company’s recently completed drilling program.
This modelling was undertaken to assist in the ongoing exploration of the project, and to refine estimates1 of volume/tonnage of the highly magnetic BIF.
The combined estimate over portions of Apollo’s licence (E47/1379 – Mt Oscar) and the recently acquired Mt Oscar East (E47/1304) is an exploration target1 of 350 million tonnes (“Mt”) to 650Mt of magnetite-bearing BIF, grading 31% to 37% iron in situ.
This modelling is based on interpretation and modelling of geophysical data, rock-chip sampling and the December 2009 RC drilling information from Mt Oscar, and geophysical data and rock-chip sampling at Mt Oscar East.
Float mapping at the Ibis Prospect confirmed the presence of near-surface magnetite-rich metasediments similar to those observed at Sequoia.
Interpretation of airborne and ground magnetic data acquired by earlier explorers indicates that the Ibis anomaly comprises a number of parallel bands of magnetic material, ranging in thickness from 20 m to 50 m, occurring discontinuously over a total strike length of 4 km.

Salares Lithium Inc. reports the results of the first phase of a transient electromagnetic survey (“TEM”) completed on the northern portion of the Salar de la Isla. This salar is part of the Company’s Salares 7 project in Region III, Chile. The TEM survey was carried out by Geodatos SAIC (“Geodatos”) of Santiago, Chile, and was designed to define the size and extent of the brine pool within the salar. The majority of the world’s lithium production comes from salars, or salt lakes, where prospective lithium mineralization is generally hosted in brine horizons.
Salar de la Isla, which encompasses a total of 16,500 hectares, is approximately 15 kilometres (“km”) long and 6 km wide on average. The northern area surveyed and studied comprises approximately 10,750 hectares, which is approximately 65% of the areal extent of the salar. Using the results obtained from the 38.5 line km survey, Geodatos has constructed a three dimensional model of the distribution of the interpreted brine bearing horizon. Using a resistivity cut-off of 1 ohm/metre (interpreted by Geodatos as definite brine), Geodatos has calculated the brine bearing horizon within the northern portion of the salar to have a volume of 2.459 billion kilolitres (kilolitres are equivalent to cubic metres). Using a resistivity cut-off of 2 ohm/metres (interpreted by Geodatos as possible brines) the calculated volume of this horizon increases to 5.393 billion kilolitres.
A gravity survey is being initiated on Salar de la Isla as the TEM survey was unable to penetrate to the base of the salar which indicates that the salar has a depth in excess of 200 metres. There is potential for additional brine bearing horizons beyond where the TEM was able to penetrate to.
“We are excited about the volume calculation identified by Geodatos and the fact that it only accounts for the northern portion of one of the Company’s seven salars. The experience Geodatos represents regarding the TEM survey and the relationship of the correlation of 1 ohm/metre as definite brine with potential of brine up to 2 ohm/metre, is encouraging. The Company will now be required to drill/sample the extensive interpreted brine horizons before a porosity value and a resource calculation can be established”, commented Todd Hilditch, CEO of the Company.
The Company intends to complete an additional 13 kms of TEM survey lines on the southern portion of the salar to enable the entire salar to be modelled in a similar fashion. Further, some of the existing lines will be extended to completely investigate the lateral extent of the interpreted brine bearing horizon. In order to fast track the exploration program on the remaining six salars, the Company has instructed Geodatos to double the size of the geophysical crew.
The TEM survey lines for Las Parinas were extended beyond the boundaries of the salar on to areas covered by alluvial and / or volcanic material. The survey identified a continuous brine bearing horizon that extended up to 2.5 kms from the salar edge and underneath the adjacent rocks. The three survey lines averaged approximately 9 kms long each.
Using the results obtained from the 26.5 line km survey, Geodatos has constructed a three dimensional model of the distribution of the interpreted brine bearing horizon. This horizon extends from surface to a depth of 170 metres.
Using a resistivity cut-off of 1 ohm/metre (interpreted by Geodatos as probable brine), Geodatos has calculated the brine bearing horizon within the surveyed portion of the las Parinas to have a volume of 1.177 billion cubic metres. Using a resistivity cut-off of 2 ohm/metres (interpreted by Geodatos as possible brines) the calculated volume of this horizon increases to 4.009 billion cubic metres.
Management is very encouraged by these initial geophysical results and intends to commence the brine sampling program as soon as the relevant equipment can be secured and moved on-site. Results from additional TEM and gravity surveys will be released as interpreted and received from Geodatos.
In January 2009, Pele Mountain announced the staking of more than 1,000 mining claim units totaling approximately 18,750 hectares in the Pigeon River area of Northwest Ontario, about 80 kilometres west of Thunder Bay. The 100-percent owned property covers very large unexplored magnetic targets with potential to host nickel (“Ni”), copper (“Cu”), and platinum group elements (“PGE”) mineralization.
The property lies in the Proterozoic Superior Mid Continent Rift, a geological setting with proven potential to host mafic-ultramafic igneous systems associated with the rifting of the Archean cratons. Pele’s exploration target at Pigeon River is a massive sulphide deposit similar to recently discovered magmatic sulphide deposits hosted in an ultramafic body or conduit, such as Kennecott`s Ni/Cu/PGE deposits at Eagle (in Michigan) and Tamarac (in Minnesota) and Magma Metals’ PGE deposit northeast of Thunder Bay.
The Lalor deposit was discovered in March 2007. The deposit is located in the Chisel Basin portion of the Flin Flon Greenstone Belt and is believed to be the largest VMS deposit found in this region to date.
Zinc rich base metal zone: Mineralization occurs in six separate stacked lenses of zinc rich polymetallic near solid to solid sulphide mineralization approximately 570 meters to 1,170 meters below surface. In October 2009 an Indicated Resource of 12.3MT 1.6 g/t Au, 24.2 g/t Ag, 0.66% Cu, 8.70% Zn, and an Inferred Resource of 5.0MT 1.4 g/t Au, 25.5 g/t Ag, 0.57% Cu, 9.39% Zn were disclosed.
Gold zone: Low sulphide precious metal intersections associated with chalcopyrite and galena. In January 2009, HudBay reported the discovery of a new gold zone with the potential to have principal credits derived from gold mining and on October 8, 2009 announced a conceptual estimate of a potential gold zone, interpreted as five discrete mineralized lenses that can contact the near solid sulphide zinc rich mineralization.
Copper-Gold zone: Disseminated to near solid chalcopyrite with lesser pyrrhotite and minor pyrite, sphalerite and galena located to the north of Gold zone 27 at approximately 15 to 20 degrees down plunge and at vertical depths of between 1,200 and 1,300 meters.
For more details on the Lalor deposit, including the resource estimate for the zinc-rich base metals zone and the conceptual estimate of the potential Gold zone, please refer to the NI 43-101 compliant technical report for Lalor dated October 8, 2009 and the company’s September 22, 2009, October 8, 2009 and December 17, 2009 news releases, available at www.SEDAR.com.
The Lalor deposit is approximately 15 kilometers from HudBay’s concentrator in Snow Lake, Manitoba, an area that is a significant past producer of gold. The ongoing evaluation, exploration and development of the Lalor deposit is a primary focus for the company, as the Lalor deposit could be of significant financial benefit to HudBay and support substantial long term activity in the Snow Lake area.
The RN-10-05 hole, targeting an airborne geophysical survey (VTEM) anomaly, has been started, with an anticipated hole length of 500 m. These holes are testing targets in the Magoo Lake area, located approximately 1.5 km northwest of the Discovery Zone. Five additional holes ranging in depth between 325 m and 700 m are planned and will target VTEM, DeepEM surface survey and Borehole Pulse EM geophysical survey anomalies. Total drilling anticipated in this program is estimated to be 3,000 m.
Hole RN-10-10 will target a large conductive modeled plate near the recently completed drilling on the Tower Zone, and is planned to be 700 m in length. Company geologists have recognized the potential extension of the Discovery Zone rhyolite in this area. This target will be drilled later in the program, as it can be drilled from ground that is accessible all year round.
Deep penetrating ground geophysical surveys have identified new conductive targets northeast and along strike of the Tower Zone over a strike length of approximately 1 km. These are untested anomalies and deeper than any previously drilled in the northeast Tower area. Three holes, each testing a new anomaly, will be drilled. Anomalies have been modeled below 300 m from surface. Hole RN-10-09 will test the deepest target in the area and has a planned length of 700 m.
drill holes RN-10-07 and RN-10-08 will test geophysical conductors located in the vicinity of an historical drill hole which reported multiple intervals of disseminated, stringer and near solid to solid sulphide, with anomalous copper, zinc and silver values in altered volcanic rock. Reprocessed historical geophysical survey data, including bore hole survey data, has been merged with VMS VTEM airborne survey data and more recent ground deep EM survey results.
These three drill targets, located on mining claim P6805E, are spatially associated with the Company’s recent surface pulse electromagnetic survey that outlined several highly conductive plates directly associated with, or flanking, a magnetic response.
A VTEM anomaly with a coincident magnetic high defined on mining claim P5643E will also be drilled. It is located approximately 2 km east-northeast of the Phase 1 Tower Zone drilling area. This target has a lateral extent of over 700 m and based on modeling of electromagnetic data is suggestive of stacked conductive zones. Historical drilling results in the area have reported strongly altered volcanic rock and sulphide mineralization with anomalous copper and zinc. The geological setting of these conductors is interpreted to be very favorable for hosting base metal massive sulphide-type deposits of the Flin Flon-Snow Lake belt.
Drilling on mining claim P1019F will target two separate VTEM anomalies near Magoo Lake. Historical work completed by Noranda Exploration in this region outlined highly anomalous copper and zinc values in a highly chlorite-altered volcanic host rock. This geological setting is also favorable for the formation of base metal massive sulphide mineralization and two holes are planned to test the targets.
