J-Pacific Intersects 5.73g Au/t over 1.75 metres on the Blackdome No. 17 Vein
Promising assay sample includes 31.2g Au/t over 0.25 metres
VANCOUVER, OCTOBER 9, 2007 - J-Pacific Gold Inc. ("J-Pacific"; TSXV - JPN, OTCBB - JPNJF) said today that it has intersected 5.73g Au/t over 1.75 metres at its Blackdome Gold Mine, located in the Clinton Mining District of British Columbia, approximately 250 kilometres north of Vancouver.
In making the announcement today, John Harrop, J-Pacific's Senior Geologist, said, "The primary objectives of the 2006 and 2007 Blackdome drill programs were to test several targets generated from past work - to gain a better understanding of mineralized structures under the Blackdome peak; to extend the principal producing veins northward along strike toward the dome; and to test the intersection of the No. 1 and No. 2 veins at depth." The 2007 Phase 2 program was an aggressive plan primarily designed to drill-test an area under the Blackdome peak, which received only minor attention during the life of the mine. The still wide spacing of the drill holes along strike clarifies the trace of a mineralized structure. "The assay results point to the potential for ore grade zones within the No. 17 Vein structure, which is now known to extend through the dome - much farther than previously realized," said Harrop. "This also increases interest in parallel features s
uch as the Giant and Redbird veins, which will receive more attention in the future."
Three holes, totalling approximately 723 metres, were drilled to test the No. 17 Vein between the southern extent of earlier drilling and Blackdome's basalt cap. Two holes targeted the same level as the portal on the No. 17 Vein (1,950 metres ASL), and one went deeper (1,890 metres ASL). As well, four holes totalling 844 metres were successfully drilled through the basalt cap. One hole was lost at approximately 61 metres, due to difficulties in overburden. All four holes reached the No. 17 Vein, and at least two intersected what is believed to be the continuation of the No. 1 and No. 2 veins as they curve into the No. 17 Vein.
Drilling under the basalt cap at the peak of Blackdome revealed that the No. 17 Vein continues through the peak and down the western side of the mountain, parallel to the Giant and Redbird veins. An intersection west of the basalt cap in the northernmost hole of the 2006 drilling, intersected this vein, but lack of additional data prevented its association with the No. 17 Vein. Importantly, this demonstrates that the No. 17 Vein does not become either the No. 1 or No. 2 Vein, but instead is a through-going structure against which the No. 1 and No. 2 veins end, forming a prospective intersection zone beneath the basalt cap.

NO. 4 VEIN
A single short hole (B07-18, 118.3 metres in length) was used to test the No. 4 Vein at depth. The intersection in core returned 1.42g Au/t over 1.2 metres. This vein can be traced on the surface for about 250 metres and runs obliquely between the Redbird and Giant veins, parallel to the No. 1 and No. 2 veins. The intersection of the No. 4 and Giant veins is a target for the next drill program.
NO. 1 AND NO. 2 VEIN INTERSECTION AT DEPTH
Four holes (B07-07A, B07-08, B07-09 and B07-10, 340.5, 299.9, 237.1 and 257.0 metres in length, respectively) were drilled to test the projected intersection of the No. 1 and No. 2 veins at depth. Hole B07-07A re-entered hole B06-07A and extended it by 38.8 metres. Testing of this target did not return any assays over 1g Au/t. No further field work is currently recommended on this target. However, the results are under evaluation to determine their contribution to understanding depositional controls of the gold mineralization.
BACKGROUND
Located in the Clinton Mining District of British Columbia, approximately 250 kilometres north of Vancouver and 70 kilometres west-northwest of the town of Clinton, the Blackdome Gold Mine yielded 240,000 ounces of gold from 338,000 tonnes of ore between 1986 and 1991.
Currently, the Blackdome Gold Mine has an inferred mineral resource (A. Boronowski, 1999), as reclassified by SRK Consulting (2001), of 124,120 tonnes, averaging 12.8g Au/t and 33.7g Ag/t, totalling 50,834 ounces of gold and 134,386 ounces of silver. The infrastructure and processing facilities remain at the mine, as do the majority of permits for operation.
The 2007 drill program consisted of 13 holes, totalling 2,079.3 metres. Twelve of the 13 holes successfully reached their targets. The drilling focused on gaining/obtaining sufficient new data to better understand the structural formations under the Blackdome basalt cap.
Analytical work was performed by Acme Analytical Laboratories Ltd. of Vancouver, Canada, an ISO 9001 certified company. Assay work is supervised by British Columbia Certified Assayers. Samples submitted to Acme were dried and crushed to 70 per cent passing through a 10 mesh screen (two-millimetre or smaller fragments). Splits of 500 grams were taken from this material and pulverized so that 95 per cent of the material passed through a 150 mesh screen. A 30 gram sample was taken for fire assay from the fine fraction. The entire coarse fraction was assayed. A weighted average was used to combine the results to represent the gold content of the 500 gram sample. For certain mineralized samples, two 500 gram samples of the initial crush were used to replicate the analysis. Some difference in gold levels is expected due to the natural gold variation within the samples. Variation between the replicates was within expected ranges, and the weighted average of the comb
ined intervals did not differ significantly. Replicate analyses were conducted by ALS Chemex of North Vancouver, Canada, an ISO 9001 certified company.
Coast Mountain Geological Ltd., a Vancouver-based geological services consulting company, is undertaking the exploration program under the supervision of John Harrop P.Geo., J-Pacific's Senior Geologist and the qualified person for this project as defined by NI 43-101 regulations, who has reviewed and approved this news release.
