Pelangio Advised of Excellent Results from Preliminary Metallurgical Testwork at Detour Lake, Ontario

TORONTO, ONTARIO--(Marketwire - March 26, 2008) - Pelangio Mines Inc. (TSX:PLG) ("Pelangio" or the "Company") has been advised by Detour Gold Corporation (TSX:DGC) that it has received excellent results from preliminary metallurgical testwork at its Detour Lake property in northern Ontario.

Pelangio has a 49.0% equity interest in Detour Gold (20 million shares). Detour Gold issued a press release today, the verbatim text of which follows"

"Detour Gold Reports Excellent Results from Preliminary Metallurgical Testwork at Detour Lake, Ontario

(Overall target gold recoveries of 91% to 95% are expected)

Detour Gold Corporation (TSX:DGC) ("Detour Gold" or the "Company") today announces the first results of metallurgical testwork on samples from the Detour Lake deposit which as of December 2007 contained an open pit resource of 4.8 million ounces in the measured and indicated categories (89.9 million tonnes grading 1.67 g/t gold) and 3.0 million ounces in the inferred category (63.2 million tonnes grading 1.49 g/t gold), using a gold price of US$575/oz (equivalent to a cut-off grade of 0.64 g/t gold and capped at 20 g/t gold) (refer to press release December 11, 2007).

Composite samples were prepared from assay rejects and drill core (HQ) at SGS Lakefield Research Limited, Lakefield, Ontario representing the full suite of geological rock types taken laterally and vertically throughout the current mineral resource.

Initial testwork results indicate excellent gold recoveries, ranging from 91% to 95%, using a standard gravity/cyanidation/carbon-in-pulp circuit (refer to table on page 2). Mineralogical examinations have confirmed that a large portion of the contained gold is present as free gold particles. High gravity recoveries in the range of 32% to 53% are being achieved in the test program. Reagent consumptions (both cyanide and lime) are low, being less than 0.6 kg/t. Testwork also indicates that a very low tail grade (non-recoverable gold which goes to the tailings) of 0.08 to 0.10 g/t gold is achievable.

With these very positive test results, the Company anticipates that the future operation would realistically be able to recover between 30% to 45% of the gold by gravity methods followed by cyanidation which would recover over 90% of the remaining gold in the circuit to give a combined circuit recovery target in the range of 91% to 95%.

Further metallurgical and comminution work are ongoing and the final process design flowsheet for the feasibility study is expected in the coming months.

Gerald Panneton, President and CEO of Detour Gold stated: "We are extremely satisfied with the overall recoveries, which indicate a very simple metallurgical flowsheet. Additional testwork in the coming months will define the optimal development route (throughput and capacity) so we can proceed with ordering the long-lead items such as the grinding mills by mid-year. We are on schedule to complete an updated mineral resource estimate by the end of June and a feasibility study by the end of 2008."

The metallurgical testwork is under the supervision of Melis Engineering Ltd. of Saskatoon, Saskatchewan. The technical contents of this release have been reviewed by Lawrence Melis, P.Eng., of Melis Engineering Ltd., a Qualified Person pursuant to NI 43-101.

(1) MF (mafic flow), KMF (potassically altered mafic flow), PF (pillow
flow), and KPF (potassically altered pillow flow) make up 87% of the
current mineral resource while the TC (talc schist) and CG (chloritic
greenstone) make up another 10%. The CBPF (carbonatized pillow flow) and
CH (chert) make up only 2.3% and as such are excluded from the table
herein.
(2) A total of approximately 2,300 samples of assay rejects representing
seven of the eight rock types (not including CG) were sent to Lakefield
for sample preparation and metallurgical testing. Since the sample
availability for the four minor rock types (CBPF, CH, TC and CG) was
limited, separate drill core samples (whole core) of these rock types
were received from the site for use in metallurgical testing.

Cautionary Note to U.S. Readers

This press release uses the terms "measured resources", "indicated resources" and "inferred resources". The Company advises readers that although these terms are recognized and required by Canadian regulations (under National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101")), the United States Securities and Exchange Commission does not recognize them. Readers are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. In addition, "inferred resources" have a great amount of uncertainty as to their existence, and economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, or economic studies, except for a Preliminary Assessment as defined under NI 43-101. Investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable."
