MacDonald Mines Exploration Ltd.  announces that it has finalized an agreement to acquire 100% of the Hornby and Pender Properties, located in the “Ring of Fire” area of the James Bay Lowlands, with Temex Resources Corp. An exploration update follows the agreement details below.

The Hornby Property

MacDonald Mines Hornby Property is located contiguous to the KWG/Spider “Big Daddy” chromite deposit. The Company believes, based on a total review of its airborne survey and historical exploration data, that the Hornby Property has the potential to host the extension of the Big Daddy deposit.

The Property also exhibits prospective volcanogenic massive sulfide (VMS) (copper, zinc and lead) geophysical targets and is on same stratigraphy as Spider/KWG McFauld’s Lake VMS discovery. Historical drilling in the proximity of this prospective target intersected VMS mineralization.

Exploration Update

As detailed in the Company’s recent press releases, MacDonald Mines has several significant mineral opportunities across multiple properties in the James Bay Lowlands. The spring 2010 drill program consisting of 26 holes, 4,471 meters and focused on the McNugget Property and identified new VMS mineralization of substance on four fold limbs.

A summary of the highlighted drill holes reported were as follows;

Copper (Cu)

• Hole MN10-102 intersected 1.03% over 15 metres
• Hole MN10-111 intersected 1.04% over 5 metres
• Hole MN10-90 intersected 1.11% over 5 metres

Zinc (Zn)

• Hole MN10-104 intersected 3.3% over 9 metres
• Hole MN10-106 intersected 2.55% over 4 metres
• Hole MN10-110 intersected 2.82% over 5 metres
• Hole MN10-102 intersected 2.5% over 3 metres
• Hole MN10-104 intersected 2.00% Zn and 0.88% Cu over 6 metres

Silver (Ag)

• Hole MN10-87 intersected 13.32 g/t over 5.3 metres
• Hole MN10-94 intersected 16.56 g/t over 4 metres
• Hole MN10-102 intersected 11.67 g/t over 3 metres
• Hole MN10-104 intersected 11.97 g/t over 3 metres

Final assays from this last phase of drilling are pending and will be reported once they have been received and reviewed by the Company.

This large VMS system, which is open in all directions and yields VMS mineralization over a potential cumulative strike length of approximately 20 kilometres, was described by consulting geologist Hadyn R. Butler, P.Geo, as potentially being a new VMS camp.

Next Phase of Drilling to Commence Early September With 2 Drills

Crone Geophysics’ down-hole and surface EM system was employed in the previous phases of exploration, assisting in the discovery of the four VMS mineralized fold limbs, and will again be utilized for the upcoming drill program for drill target control.

The Company will continue to operate two drills for this upcoming drill program and will focus on the positive results from its successful spring 2010 drilling program on the McNugget Property.

Targeting Nickel and VMS on McNugget Property

VMS

The pyrrhotite-chalcopyrite-sphalerite-pyrite mineralization observed in the core of the McNugget property is indicative of VMS mineralization. The pattern of chlorite and sericite alteration, coupled with varying Cu/Zn ratios and alteration index plots from available geochemistry, indicates that there are at least three separate hydrothermal discharge vents/centres found within the same stratigraphic horizon of a large fold complex (McNugget).

Sulphide mineralization observed in drill core generally appears between footwall metasediments and hangingwall felsic volcanics, a lithologic sequence indicative of a Bimodal-Siliciclastic VMS environment.

Based on alteration mineralogy, geochemical vector analysis and 3-D geophysical modelling, it appears that the significant VMS mineralization intersected to date is peripheral to the volcanic centres (sources).

The Company’s current information is pointing to the Fold Nose found on the property as the most immediate prospective appreciable VMS mineralization. A surface and airborne electromagnetic (EM) survey are currently underway on the Fold Nose – and these results will direct the drilling program.

Nickel

The highest priority nickel target on the McNugget property remains to be in the vicinity of MN07-39. A completion of the airborne magnetic and EM, and Noront Resources’ recent image of the Eagles Nest indicates that the same magnetic horizon extends from the Noront discovery through the McNugget property – adjacent to MN07-39. Prior to further drilling, this area will be investigated further using the following geophysical techniques – VTEM and AeroTEM IV, magnetics, and Crone Geophysics surface and down-hole pulse EM system.

MacDonald Mines Exploration Ltd. anounces that it has recommenced its 2010 exploration drilling program in the Ring of Fire, James Bay Lowlands.

The Company will be utilizing two drills for this phase of drilling and will focus on the results from its successful spring 2010 drilling program.

The spring 2010 drill program on its McNugget Property identified new volcanogenic massive sulfide (VMS) mineralization on four fold limbs.

Targeting Nickel and VMS on McNugget Property

“The McNugget Property has moderate to high potential for both Cu-Zn volcanogenic massive sulfide and Ni-Cu-PGE sulfide deposits.” – Dr. Tucker Barrie, P. Geo.
This phase of drilling will focus on five principal base metal occurrence areas: 1) Campbell (Cu-Zn, to northeast); 2) Campbell West (Cu-Zn, north central); the 3) Fold Nose (Cu-Zn, to northeast); 4) Southern (Cu-Zn and Ni-Cu, to south); and 5) Area 39 (Ni-Cu-PGE, to southeast. (Figures are available on MacDonald’s website at www.macdonaldmines.com). Initial drilling will be concentrated on the four VMS horizons identified through the previous drilling and geophysical investigations.

East Portion of McNugget Property on Same Stratigraphy as Noront’s Eagles Nest

Unlike Noront’s discovery, the EM conductors (2) in the vicinity of MN07-39 are greater than 300m in strike length (based on both VTEM and Crone PEM – surface and borehole) compared to the Eagles Nest 100-200m strike length.  Six DDH holes are targeted in this area to explain the EM anomalies during the current drill program.

Company Provides  Detailed Outline of  Voisey’s Bay-type Target on Hulbert-Salo Property

The Company has staked 14 mining claims covering an area of 3,140 hectares with magnetic and EM (VTEM survey) characteristics of an intact ultramafic-gabbroic intrusion.  Modelling of these data results in a spoon-shaped intrusion with multiple internal structures, similar in size and shape of the Voisey’s Bay complex which hosts numerous Ni-Cu deposits.

The VTEM/Mag conducted over the Property has identified an anomaly approximately 10.9 km long by greater than 3.3km wide at its widest.   Historical prospecting over the area identified both gabbroic and ultramafic rocks. An interpreted “feeder zone/dyke” exists to the west of the main intrusive.  The most prospective EM conductor - the primary nickel target – is located just above the throat of the feeder dyke, similar in position to the Ovoid at Voisey’s Bay. A 3D model of the magnetic data is available on our website.

“It is both unusual and highly prospective to find a system that appears to be so intact with EM anomalies identified in groups within the magnetic network/structures (cycles or influxes)”,  comments Quentin Yarie, P.Geo. Vice President of Exploration.   “The Voisey’s Bay mineralization has been explained in terms of a model calling for repeated influxes of magma and these characteristics are obvious in the Hulbert-Salo data.”

Current short term work plans include a Crone PEM ground survey over the most prospective Nickel targets (identified from the VTEM inversion).  Upon review of this data, a drill program will be defined.  Because the Hulbert-Salo property is in a  new area MacDonald will engage in consultation with both Webequie and Kasabonica First Nations and outline the proposed first phase of drilling.  This is in keeping with MacDonald Mines established protocols regarding exploration on historical lands used by First Nation communities.

The ground geophysical program has been used by MacDonald Mines on its McNugget Property resulting in significant success in identifying targets of interest for drilling.  Based on previous experience, the Company is confident that this process can be completed quickly and with minimal impact on the ground as it requires no line cutting (GPS positioning would be utilized).

MacDonald Mines in presenting this target of opportunity cautions that drilling will be required to confirm the sources of the EM conductors.

Royal Roads Corp.

The 2010 Long Range exploration program is focussed on two areas of activity, the first being the more advanced exploration on the Portage nickel discovery and the second being frontier airborne geophysics and follow-up prospecting over the newly acquired claims recently incorporated into the Long Range property. As of June 17th, 2010, the frontier airborne geophysical surveys over the newly acquired claims was completed with results anticipated to be available in August 2010.  Once received, data will be reviewed to select targets for immediate follow-up by ground prospecting. Areas surveyed by the 1,400 line kilometre Fugro HELITEM® airborne surveys include several properties underlain by unexplored gabbro bodies recently recognized to be prospective for magmatic nickel-copper sulphide deposits. Depending on results, it is hoped that the prospecting activities will help evaluate targets for further work including testing by diamond drilling.

The Long Range property, located 64 kilometres to the southwest of Buchans, covers 381,500 hectares (381.5 km²). The exploration philosophy at Long Range is centered around the potential for discovery of a magmatic nickel sulphide deposit broadly analogous to Vale Inco’s Voisey’s Bay mine in Labrador and Kennecott’s Eagle deposit currently being developed in northern Michigan

An airborne geophysical survey flown over the initial property in 2008 detected a number of anomalies in prospective gabbro. Follow up work ultimately resulted in the discovery of the Portage Nickel prospect and the Range Copper prospect highlighted below. Additional frontier exploration is ongoing to identify new prospects in this highly prospective and un-explored region of Newfoundland.

Goldbrook Ventures Inc. announces mobilization of men and equipment to its Raglan project, Ungava, Quebec in order to carry out a planned summer field season exploration program.

Belanger Camp will support a large exploration program on the western portion of the Goldbrook properties, and an eastern camp in Kangiqsujuaq (Wakeham Bay) will support activities in the eastern tenures.  Both camps are now operational and receiving field crews. Geological field crews mobilized to these camps during the week of June 21^st.

In total five diamond drill rigs are scheduled for up to 25,000 metres during the 2010 summer season and one base-of-till rig will test geochemical anomalies identified from regional data as well as testing coincident Magnetic-EM targets identified from Airborne data.  Geophysical crews to conduct borehole geophysics and surface EM and magnetic surveys will be deployed in early July.

The 2010 exploration program, with a budget of over $17,500,000, includes a goal of 25,000 metres of diamond drilling in conjunction with an extensive program of prospecting, geochemical surveys and ground geophysics over both the east and west extensions of the productive north and south Raglan horizons. This program will follow-up on the positive results of geological, geophysical and remote sensing surveys completed in these areas over the previous years and which helped with discoveries of extensive nickel-copper-PGE sulphides at the Mystery and Timtu zones.

GEOLOGICAL SETTING

The Raglan Project area is underlain by rocks of the Cape Smith (Raglan) Belt that extends for 375 km across the Ungava Peninsula of Nunavik, northern Quebec, Canada. The Aphebian (Paleoproteozoic) Cape Smith Belt and the Thompson Belt, both hosting Ni-Cu-PGE deposits, are part of the Canadian Circum-Superior Belt that separates the Archean Superior and Archean-Proterozoic Churchill geologic provinces of the Canadian Shield.

Komatiite-associated and komatiitic basalt hosted Ni-Cu-PGE deposits occur in Aphebian greenstone belts in various locations around the world including the Cape Smith Belt, Thompson Belt and the Pechenga Belt, Kola Peninsula, Russia.

In May 2010, Borehole Induced Polarization (BHIP) surveys were done on the Tyranite and Minto properties. Results from the Tyranite hole are not yet available. 3D conductivity and chargeability models from boreholes gradient IP data have been calculated for holes M-0901 and M-0902 on the Minto property.

The Corporation has completed down-hole geophysical testing on the MacMurchy property and intersected 7.4% nickel and 2 g/t platinum and palladium over one meter in hole D6-07 confirming the nickel potential of the area. The MacMurchy property is located in the southwest corner of the MacMurchy Township some 10 km SSW of the Minto property.

Creso Exploration is currently evaluating bids for an agreement for a 200-kilometer low level airborne (Mag, VLFEM, and radiometric) geophysical survey to cover the Minto, Tyranite and Duggan zone on a 30-metre spacing in order to define geological structures and mineralized zones. Upon completion of the geophysical survey, the Corporation will undertake a 5000-meter drill program on the Minto, Tyranite and Duggan properties.

Samples were assayed at the facilities of Swastika Laboratories of Kirkland Lake (Swastika, Ontario) a certified and accredited laboratory by a standard fire assay method. All samples with greater than 1.0 g/t Au were re-assayed by a pulp and metallics method. Above interval values are weighted averages.

Creso announces drill results from the MINTO Project located half-way between Timmins and Sudbury in Ontario - 65.7 Meters of 18.2 g/t g and 79.6 Meters of 4.61 g/t Gold in Hole #2.

The Minto showing consists of a pod of carbonate sulphide breccias containing an estimated tonnage of 225,000 tons (204,000 t) grading 0.2 oz per t (6.8 g/t) Au to a vertical depth of 225m as determined and reported in 1984 by Duncan Gold Resources, (White 2007) **. Gold is related to pyrite and quartz veining trending north south and northeast southwest.

Melkior Resources Inc.  announces the completion of an airborne VTEM electromagnetic and magnetic survey of its 100% owned Broke Back and Riverbank claim groups in Northern Ontario.  A total of 1765 line kilometres were flown at a cost of approximately $300,000.  The Broke Back group adjoins the main Noront claim block, it is located 7 kilometres north of the Noront Eagle One nickel discovery and approximately 6 kilometres northeast of the chromite property of Cliffs Natural Resources Inc.  Once Melkior has received airborne data it will be interpreted and used to direct the next stage of exploration.

Melkior has previously survey a total of 3902 line kilometres of airborne electromagnetic and magnetic on its other properties in the “Ring of Fire” area namely the East Rim and the West Rim properties.  The previous data has been interpreted and locations have been selected for followup and drilling.

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.

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 VTEM survey was flown over the Pigeon River East Block by Geotech Ltd. of Aurora, Ontario. The survey has defined linear magnetic features with the potential for mafic/ultramafic conduit systems and feeder dykes into larger mafic/ultramafic intrusions. Preliminary analysis by the geophysical contractor indicates the presence of a number of, possible sulphide-related conductors, coincident with conduit-type magnetic features and other, larger, conductive anomalies with similarities to known mineralized layered mafic/ultramafic complexes. Conductive zones, possibly sulphide-related, are also found in the vicinity of a GSC lake sediment anomaly which gave anomalous values of 234 parts per million (ppm) Ni and 298 ppm Cu. Geotech has identified several high-priority, drill-ready, targets from the survey. Other priority targets require further definition through prospecting and follow-up geophysical surveys, which are planned after spring breakup. The targets are generally till or swamp covered and no previous prospecting, mapping, or geophysical surveys, other than an airborne magnetic survey flown by the GSC in 1964, are known.

The 2009 Exploration Program at the MAN, Alaska project included a new ZTEM airborne survey (Z axis Tipper Electromagnetic system), extensive geological mapping and a proprietary fluxgate time domain ground EM surveys (full waveform streaming multi sensor fluxgate array).  The 2009 geophysical programs (ground fluxgate TEM, ZTEM, and BHEM) were considered a great success.  These very compelling geophysical targets, are the best discovered to date on the MAN property and the foundation for a productive 2010 exploration program.

3D inversions of aeromagnetic data, as well as several widely spaced deep drill holes show a consistent presence of abnormally thick ultramafic bodies with localized deep feeders. Last year’s results add to the evidence that the MAN property is the main intrusive centre for Triassic magmatism that generate the extensive nickel, copper and PGE (platinum group elements) bearing ultramafic intrusions and coeval lavas within the Alaska, Yukon and BC, segments of the Wrangelia terrain.  Drill results to date come from the holes targeted using the proprietary ground time domain EM survey (TEM), in conjunction with the new ZTEM airborne survey and previous ground gravity and VTEM airborne surveys.

Interpretation of the 2009 MAN drilling results assays indicates the presence of a disseminated NI-Cu PGE (platinum group elements) concentration build up extends beyond 600 meters in DDH PNI-09-024 and over 1000 meters in DDH PNI-09-025.  Geophysical surveys show that these conductive bodies are associated with the strongest Fluxgate TEM anomalies on the property,  in addition, strong responses to the BHEM surveys indicates late channel (high conductance channels) conductivity build up beneath the drill holes.

The surveys described below were used to model the interpretation of conductive anomalies on the property. The analysis concludes that the anomalies are deep, large and very compelling.

1. ZTEM Survey – has for the first time identified at depth the shape structure, and conductive zones of the mafic and ultramafic intrusions.
2. Ground TEM – proprietary long time constant, time domain electromagnetic surveys allowed for deep search (> 800 meters) for high conductance bodies commonly associated with Ni-Cu sulphides that have been missed by previous surveys methodologies.
3. Ground and Airborne Magnetic Survey’s - these survey’s help to define the magnetic bodies below surface that often correlate to the ultramafics and mafic rocks on the property.  In addition, UBC 3D inversions and Euler 3D inversions are employed to help determine the location of the form, internal structure, and deep kneels or feeder dykes associated with the intrusive bodies.
4. BHEM Survey – a borehole electromagnetic survey is performed down the drill hole to detect conductive anomalies within, beside and below the drill hole to aid in the correlation with the new high priority, long time constant, surface TEM survey results constraining more accurate location of the conductor.

One of the most exciting targets from the 2009 geophysical program was the identification of the location for drill-hole PNI-09-025 based on the initial results from the TEM surveys.  The hole was drilled to a depth of 1066 metres and terminated due to the limitations of the drill.  The BHEM (down hole geophysical survey) showed an increasingly large response towards an anomaly below the hole’s final depth.

Low-frequency borehole electromagnetic surveys (BHEM) were carried out in five of the 2009 drill holes, as well as seven older drill holes. A number of moderate to strong off-hole conductors were detected and are being evaluated as follow-up drill targets for the 2010 program. Three holes (07-001, 09-023 and 09-025) show anomalous increases in late time channels indicative of deep conductors below the base of the holes. These deep conductive zones correlate with high-priority long time-constant surface TEM anomalies.

Extensive geophysical work was conducted concurrent to the drilling program.  In particular, a new ground time domain EM system (full waveform streaming multisensor fluxgate array), was deployed extensively through the latter half of the exploration season.  This was the first instance of this technology being used in North American nickel exploration.  This ground based EM technology developed by Dr. Mark Shore (Magma Geosciences Inc.) provided Pure Nickel exploration team with the ability to collect low-noise late time data under challenging conditions and identify electromagnetic anomalies at greater than  800 metres depth.

Dr. Mark Shore is going to represent example of using of lower frequencies induction coil, SQUID and fluxgate sensors on the nearest PDAC in Toronto: http://www.pdac.ca/pdac/conv/2010/pdf/presentations/ts-mark-shore.pdf.

Canadian Arrow Mines Ltd. reports the discovery of a new nickel copper sulphide mineralized zone while drill testing the Night Danger exploration target area. A nine metre wide section of stringers and blebs of sulphides assayed 0.57% Ni and 0.45% Cu. Two sections within this interval assayed greater than 1% nickel. The Night Danger area is a new showing identified by the company and has no previous exploration history. The Night Danger target was identified during the Canadian Arrow 2008 VTEM Airborne Survey in the Turtlepond Lake Area. The program completed in early 2008 consisted of a Versatile Time Domain Electromagnetic (VTEM) helicopter -borne geophysical survey which included 1,057 line km of survey covering an area of approximately 77 km2. The survey included coverage of the Ghost Lake, Emmons Lake, Prigg, Glatz, Turtlepond Lake, Eva Lake, and Kawene Lake Projects, and portions of the Kenbridge Project and Denmark Lake Project. Numerous more untested anomalies were identified that will comprise the regional exploration focus into 2008 and beyond. The well pronounced anomaly, detected on two adjacent 100 metre spaced flight lines, is situated in a swampy area with no surface exposure. Diamond drill hole ND-09-1 intersected two separate intervals of sulphide mineralization between 63.45 and 88.05 metres down the hole. Narrow sections of up to 1.3% Nickel are contained within the lower sulphide horizon.
At the Glatz area six diamond drill holes (1,056 m) were completed to test surface showings with coincident geophysical anomalies.
Sections of disseminated and blebby sulphides have been intersected; however the mineralization between holes is indicated to be narrow and discontinuous.Deeper penetrating ground geophysical surveys will be completed at the Night Danger and other areas. Additional drill results to be reported from the Emmons Lake and Double E target areas are forthcoming.
