UPDATE ON 2008 DRILLING AT MACLELLAN GOLD MINE, LYNN LAKE

Toronto, Ontario, May 15, 2008:   Since Diamond drilling commenced in the first week of March 2008 Carlisle Goldfields Limited (TSX: CGJ) has completed a total of 15 drillholes, with two others still in progress, for a total of 6,146 metres.   Drilling continues on the intended program of about, 8,000 metres, in 20-25 holes.  Drilling completed to date is listed in the following table.

The program has been testing all of the zones at the MacLellan Mine from east to west, and below the mine workings.  Additional mineralization has been targeted to the south of the mine areas, and to the west of previously mined areas where drilling in the Rainbow Zone has provided a number of intervals with visible gold.  Over 2,367 samples have been taken of mineralized sections and shipped to TSL Labs in Saskatoon for analysis, results for over 1,400 samples are pending, with lab turnaround averaging about 4 weeks.

Partial results are available for drillhole MG-08-08, which intersected a wide zone of mineralization, including a number of higher grade intervals in the East Main Zone.  This hole suggests that the mineralization may be becoming more consistent in grade and thickness at depth.  Silver values continue to be in the range of 3-5 times the grade of Gold in any assay interval.  It is anticipated that silver values will contribute in a major way to the economics of a future mining operation.

* true width will be about 85-90 % of  core length.

Drill core is logged, and saw split, on site. One half of the NQ diameter core is shipped to TSL Laboratories, Saskatoon, Saskatchewan, "an ISO 9001:2000" accredited laboratory, for analysis. TSL protocols include fire assay for Au and Ag with an ICP finish on a crushed and pulverized sub-sample. The MDL and upper detection limits (UDL) for Au are 5 - 1000 ppb under this protocol, and 0.2 - 50 ppb for Ag. Above the UDL a gravimetric method is used for determination on high concentrations.   A quality control program has been implemented to ensure best practices in the sampling and analysis of the drill core. Certified control standards, and coarse field blanks were inserted into the sample stream. A program of analysis of duplicate samples will be undertaken. Mr. Stephen Mlot, P. Eng., the President of the Company, is the qualified person for this press release.
