Pacific Booker Minerals Inc. Announces Resource Update

Vancouver BC, April 13, 2007: Pacific Booker Minerals Inc. is pleased to announce that a new resource estimate has been completed for its wholly owned Morrison porphyry copper/gold/ molybdenum deposit, located 35 km east of Granisle, BC. This resource estimate is an update from a resource estimate provided in the August 1, 2004 Beacon Hill Consultants Ltd. report entitled "Preliminary Assessment, Morrison/Hearne Hill Project". This resource estimate will also be the basis of a feasibility study that is currently being prepared by Wardrop Engineering Inc.

The table below presents the updated Morrison resource estimate using a cut-off grade of 0.3 % Equivalent Copper. The copper equivalent was calculated using relative recovery and metal prices of $1.78/lb copper, $465/oz gold and $10/lb molybdenum. Composited intervals from 98 drill holes representing 22,982 m of core were used in the block model estimation. Gold grades were capped at 1.5 g/t prior to compositing.

An area of elevated molybdenum grade occurs in the southeastern portion of the deposit and includes 49 million tonnes of combined measured and indicated material grading 0.40% Cu, 0.15 g/t Au and 0.01 % Mo.

Ronald G. Simpson, P.Geo., principal of Geosim Services Ltd., completed the resource estimate for the project and is an independent qualified person as defined by NI 43-101. A detailed 43-101 compliant technical report will be completed and filed on SEDAR within 45 days.

Methodology & Quality Control

These mineral resource estimates were prepared pursuant to Canadian Institute of Mining (CIM) Standards on Mineral Resources and Reserves, prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council December 11, 2005 and published in the CIM Bulletin of November 2005 and compliant with National Instrument 43-101 - Standards of Disclosure for Mineral Exploration and Development and Mining Properties. Numbers have been rounded subsequent to calculation.

Resource estimation was constrained by a 3-dimensional solid models developed from geological and analytical data. Block size was 20x20x12 metres and grade estimation was carried out by the ordinary kriging using 6 metre downhole drill composites. Blocks were estimated in three passes using incremental search distances. Tonnes were calculated using an average SG of 2.72 except for the East Fault zone where an SG of 2.6 was used. The SG values were based on 309 measurements of drill core. In order to be classified as measured, a block was required to have at least 6 composites within a radius of one third of the corresponding variogram range for each zone (62 - 67 metres) and in at least 5 adjacent octants. To be classified as indicated, a block was required to have at least 6 composites within a radius of two thirds of the variogram range (121 - 133 metres) and in at least 3 adjacent octants. All other estimated blocks were assigned to the inferred category.

Exploration on the Morrison project was conducted under the supervision of E. T. Kimura, P.Geo, who was the Company's Qualified Person as defined under NI 43-101. Drill samples for analysis averaged 3.05 metres in length of split NTW and HQ-size core. All drill programs since 2000 utilized modern QA/QC practices involving insertion and monitoring of reference standards, duplicates and blanks.

All analytical work was conducted by Acme Analytical Laboratories Ltd., an ISO 9001 registered facility, located in Vancouver. Samples for check assays were submitted to ALS Chemex, an ISO 9001 registered facility, also located in Vancouver.
