Loch Harris Announces Launch of EM-1 Explosive Detection Technology.

Business Editors

AUSTIN, Texas--(BUSINESS WIRE)--June 28, 2001

Loch Harris, Inc. (OTC: LOCH) announced that in late March 2001 a three-person team representing Loch Harris conducted a third-party Quality Assurance mine detection sweep of a construction site on Kinmen Island off the coast of mainland China for the Taiwan Power Company (Taipower). The primary mine clearing operation was conducted by BACTEC International Limited over one month before Loch Harris arrived on site. The Loch Harris Team used the EM-1 to conduct the sweep. The EM-1 is the first generation mobile, explosive detection device developed from Loch Harris' ELF technology. The EM-1 was developed by a team of engineers and scientists spearheaded by Dr. Wade Poteet and Tim Shriver.

The EM-1 (an explosives detection process) was selected for the third-party QA sweep because it uses a different technology than that used in the primary clearing efforts (primarily a metal detection process). This redundancy of effort and diversity of technology was intended to provide Taipower additional assurance of the effectiveness of the primary sweep efforts. The area of work was approximately 250 meters long and 60 meters wide with a predominantly sandy soil leading down to a substantial tidal beach zone

During its primary clearing operations, BACTEC identified and cleared over 170 mines and several unexploded ordnances (UXOs). The mines were very old, had metallic cases and used TNT as the primary explosive. The explosives uncovered in the primary clearing operations were all removed by BACTEC for later disposal. Loch Harris coordinated with and received excellent support from BACTEC.

The Loch Harris Team consisted of Malcolm Philips, Tim Shriver and one EM-1 operator. Dr. Wade Poteet from his offices in Tucson, Arizona provided technical support. The Loch Harris Team swept 20 areas (ranging in size from one square meter to sixteen square meters) selected in conjunction with Taipower. The areas selected were biased to the general areas where mines had been previously found and where future excavation was planned.

The EM-1 identified areas where evidence of explosives or iron was present. Thirteen sites (six of which were located in one area) were identified by the EM-1 as requiring further analysis to clear explosive signatures - all were later understood to be areas where mines or one of the UXOs had been located and removed. In one location, the EM-1 tracked the explosive signature down about 1.5 meters before receiving the "clean" signal. Afterwards the Team was told that a 110-pound bomb had been found at that location.

The results of the Team's QA effort provided Taipower with further assurance of the effectiveness of the primary sweep. Taipower monitored the Team's activities and was provided with a verbal report when the Team left the site.

After returning from Taiwan, the Loch Harris Team analyzed the raw data from the QA sweep effort, conducted confirmatory tests of the equipment and configurations used and on June 26, 2001 filed a written report with Taipower to close out the project. (A copy of the final report is being placed on the Loch Harris Web Site.) The Team was pleased with the performance of the EM-1 and with the logistical support received from the entire Loch Harris organization.
