Acquisitions

Porphyry Creek Property, Rocher Deboule Mountains, British Columbia

Duncastle Gold (formerly Dundee Mines Ltd.) also reported today that it has
optioned the right to acquired a 100% interest in the Prophyry Creek property
comprising 21 mineral claims totaling approximately 7,216 hectares and located
in the Rocher Deboule mountains 10 km south of Hazelton BC and 20 km northwest
of Smithers. Six claims totaling 2,221 hectares were acquired directly by the
company. The remaining 15 claims and 4,995 hectares were acquired from a group
that includes Vancouver businessman John Norton and Duncastle Gold directors
Michael Rowley and Doug Warkentin for $300,000 cash payable over 6 years with
$30,000 in the first year, and a royalty being 2% of Net Smelter Returns.


The Porphyry Creek area is highly prospective for gold, copper, molybdenum,
silver and other minerals, and includes eleven large porphyry or porphyry-style
copper-gold, copper-molybdenum, molybdenum, and molybdenum-tungsten deposits
within a 150km radius. These deposits range from 20.6 million tonnes to perhaps
250,000,000 tonnes, with grades ranging from 0.30 to 0.48% copper, 0.03 to 0.8
grams per tonne gold, 0.013 to 0.192% molybdenum and 0.041% tungsten (1).
Mineral resources and/or reserves are reported for all these properties as a
result of years of systematic exploration. The deposits include: Bell-Granisle
(copper-gold), Berg (copper-molybdenum), Big Onion (copper-molybdenum), Endako
(molybdenum), Huckleberry Main & East Zones (copper-molybdenum-gold), Kitsault
(molybdenum), Louise Lake (copper-molybdenum), Poplar (copper-molybdenum), and
York Hardy (molybdenum-tungsten). Two of these, Huckleberry and Endako, are
currently in production. The Endako mine is Canada's largest molybdenum
producer. One small past producer lies within the claim boundaries, and three
more significant past producers lie just outside the claim boundaries.


Regional stream sediment samples show the property to be among the highest
potential in BC for an 'Olympic Dam' or Iron Oxide Copper Gold (IOCG) type
deposit. In addition a large magnetic anomaly is shown in a government
geophysical survey. No significant exploration work has been done to investigate
the potential of either IOCG or porphyry-related deposits on the Property.


The Porphyry Creek area has a long history of exploration and development from
high-grade vein systems, dating back to at least 1910. Between 1915 and 1954 the
area saw substantial production from the nearby Rocher Deboule and Red Rose
mines, as well as lesser production from the Victoria, Cap and Highland Boy
mines. Exploration has been intermittent since the closure of these mines, with
the most substantial work occurring in the 1980's on the Rocher
Deboule/Victoria, Red Rose and Killarney/Jones prospects.


Of the above mines, the Cap mine occurs within the claim boundaries and produced
26 tonnes grading 301 grams per tonne silver, 5.9% copper and 3.6 grams per
tonne gold, based on publicly available government (Minfile) data.


Minefile also lists samples from an adit at the Brunswick prospect on the
Porphyry Creek property: a composite sample taken from thirty bags of selected
ore from the upper adit graded 3,802 grams per tonne silver, 1 gram per tonne
gold, 1.91% copper, 17.27% lead and 28.4% zinc, while a second sample, also from
the upper adit, assayed 3.65 per cent lead, 4.05 per cent zinc, 1,288.93 grams
per tonne silver and 0.446 gram per tonne gold.


The acquisition of the Porphyry Creek project provides the Company with a
significant land package in a second highly prolific mineral district in British
Columbia. Initial surface work on the property will commence in late July -
early August and will involve assessment of the known mineral occurrences and
expansion of the property-wide database through a reconnaissance rock sampling
and stream sediment sampling program.


Property Acquisitions - Ymir

Duncastle Gold continues to consolidate the Ymir camp through the acquisition of
a 100% interest in eight claims totaling 884 hectares from a company insider.
The claims are contiguous with the company's current holdings which include most
of the historically successful mines within the Ymir Camp near Trail, BC in the
Nelson Mining District. The claims were acquired from Crucible Resources, a
company owned by Doug Warkentin, PEng, a Director and shareholder of Duncastle
Gold, for a cost of $2,478 being the costs incurred in acquiring and maintaining
the claims. The claims strengthen the company's land position in the area.


Exploration Update - Ymir

A 3,000-plus meter core hole drill program is planned for summer 2008 to
continue to evaluate the mineralized extensions of historic workings found in
2007 including four holes planned to test the up- and down-dip potential of the
Yukon ore-shoot where previous drilling returned values of up to 6.7 metres of
4.6 g/t Au, 46.5 g/t Ag, 1.2% Pb and 3.4% Zn from drill hole 07YG-15 (see
NR-01-08). Several targets, identified mainly through historical research, will
be tested in this round in order to identify addition undeveloped ore-shoots
along the Yankee Girl vein, other parallel high-grade veins and structural
intersections. Snow clearing of access roads has started and crews are scheduled
to mobilize in early June with anticipated drill start-up by mid June.


Corporate Update

The Company is pleased to announce the addition of Mr Derek Page to replace
outgoing director Lance Morginn. Mr Page obtained a Bachelor of Business

Duncastle Gold Corp. is a mineral exploration company based in British Columbia,
Canada with projects in both central and southeastern BC. In central BC the
Company has the 7,216 hectare Porphyry Creek property in the Rocher Deboule
mountains near Smithers BC with a porphyry or IOCG copper-gold target. In
southeastern BC the company holds 26 crown grants under a 100% option agreement
and owns 89 tenured mineral claims totaling approximately 5,376 hectares in the
Nelson Mining District, located three kilometres northeast of the town of Ymir
in southern British Columbia. Gold mineralization was first reported near Ymir
in the late 1800s, with much of the mining taking place at the Yankee Girl,
Dundee and Ymir mines during the period 1907 to 1951. Historical records
indicate that a total of 375,000 tonnes grading 9.9 g/t Au and 57 g/t Ag were
mined from the Yankee Girl vein during this time. Exploration by the company is
targeting high-grade Au-quartz veins throughout the Ymir district which
historically, together with the adjacent Sheep Creek district is reported to
have produced more than 1 million ounces of Au (2). Duncastle Gold Corp. is a
Manex Resource Group company.
