J-Pacific Reports on Montgolfier Project
Drilling Progress in Quebec
Winter drill program successfully completed, assays results pending
VANCOUVER, May 1, 2008 - J-Pacific Gold Inc. ("J-Pacific") (TSXV - JPN) is pleased to announce that it has completed the winter drill program at its Montgolfier Project. The Montgolfier Project is located in the Casa Berardi region of northwestern Quebec, some 85 kilometres west of Matagami, and 30 kilometres east of the Casa Berardi gold deposit.
Seventeen core holes totalling 9,225 metres were completed, and drilling operations wound up on April 13, 2008. An eighteenth planned hole was postponed because of weather and ground conditions.
The 2008 program was designed to test the lateral and depth extensions of gold mineralization explored in 2007. This latest program focused on three main target areas spanning 16 kilometres of strike length along the Casa Berardi Fault ("CBF"). Maps detailing the drill holes are available for download on the J-Pacific website.

Six holes (JPN08-27-34) investigated the lateral and depth extensions over a 200-metre strike length of Hole JPN07-06 (1.44g Au/t over 12.0 metres*), which is hosted within a broad muscovite-carbonate-pyrite alteration zone adjacent to the CBF. All six holes intersected the targeted structure in the CBF footwall, with weak to moderate muscovite-carbonate-pyrite alteration over 10- to 30-metre core-length intervals.* Assay results are pendin
g.
Furthermore, three holes drilled approximately 100 metres below Hole JPN07-06 (300 metres vertical depth) intersected a new muscovite-carbonate-pyrite alteration zone, some 200 metres south of the corridor along the footwall of the CBF (150 metres depth). The new structure exhibits similar intensities of muscovite-carbonate-pyrite alteration over a few to tens of metres in core length,* accompanied by minor quartz-carbonate-pyrite veining identical to the section intersected by Hole JPN07-06. In light of these results, the casings were left in three of the holes, which will facilitate future down-hole geophysical probing to trace the depth and lateral extensions of the two favourable alteration zones.
Hole JPN08-31 tested the depth extensions of JPN07-01, which intersected a weakly anomalous (< 200 ppb Au) quartz-carbonate-tourmaline vein breccia zone (eight metres core length), accompanied by strong arsenopyrite-pyrite mineralization (5-15 percent). The hole was drilled from the north, and did not intersect the targeted arsenopyrite-bearing quartz-tourmaline vein breccia. However, north of the projected depth extension it intersected several decametre-scale silica-carbonate alteration zones with disseminated arsenopyrite and pyrite mineralization (traces to eight percent over one-metre-long sections).
Ten holes (JPN08-33 to JPN08-35-42) tested the lateral and depth extensions of mineralization encountered in Hole JPN07-21 (8.1g Au/t over 3.2 metres), and JPN07-17 (10.4g Au/t over 1.0 metre). Numerous historical holes drilled during the 1980s also intersected highly anomalous gold mineralization close to these holes. Nine of the 10 holes intersected the target structure - hosted within a decimetre- to metre-scale quartz-sericite alteration envelope with up to five percent pyrite and arsenopyrite mineralization - in the CBF footwall.
Promising decametre-scale alteration patterns encountered in Holes JPN08-35 and JPN08-37A prompted allocation of contingency metres to test for lateral extensions of these alteration zones. Hole JPN08-42 was drilled 100 metres east of JPN08-37, and intersected approximately 22 metres of favourable quartz-sericite alteration with trace pyrite, at a vertical depth of approximately 300 metres; JPN08-41 was drilled 300 metres east of JPN08-35, and intersected metre-scale alteration zones, indicative of a continuous prospective alteration and mineralization envelope over 1,000 metres of strike length. Core sample assay results are pending.

BACKGROUND
The Montgolfier Project straddles the Casa Berardi Tectonic Zone, approximately 30 kilometres east of the Casa Berardi Mine, where Aurizon Mines Ltd. has outlined a mineral reserve of 3.1 million tonnes grading 9.3g Au/t (equivalent to 918,000 oz Au), with an indicated mineral resource of 3.6 million tonnes grading 5.7g Au/t (equivalent to 662,000 oz Au), and an inferred mineral resource of 5.5 million tonnes grading 6.9g Au/t (equivalent to 1,214,000 oz Au) (Source: Aurizon Mines Ltd. website).
The presence of gold reserves and resources at the Casa Berardi Mine does not necessarily indicate that gold resources will be delineated on the Montgolfier Project. However, SRK Consulting believes similarities exist in the stratigraphy and structural setting of the Montgolfier Project to those of the Casa Berardi Mine, as well as other occurrences of gold mineralization elsewhere in the Casa Berardi Tectonic Zone.
The drilling was performed by Major Drilling Group International Inc.; on-site geological expertise was provided by IOS Services G�oscientifiques Inc., a Quebec-based geological services consulting company, under the supervision of Dr. Jean-Fran�ois Couture, P.Geo., J-Pacific's qualified person for the purpose of National Instrument 43-101, who has reviewed and approved this news release.
