Dear Sir :

We wish to express our satisfaction towards your geophysical instrument called the Beep Mat BM4+, which is adapted to winter conditions. We also take the opportunity to briefly describe the prospecting method that we chose and that proved to be very successful.

The first step of the prospecting program consisted in compiling data in order to define and give priority to exploration targets for a given region. Those targets were defined from several parameters including :
• Magnetic survey (provincial government);
• Electromagnetic survey (airborne EM Input);
• Geological context;
• Geochemical signature of deposits coming from lakes or creeks;
• Access.

The compilation made us realize that several top-priority targets were located in areas hard to access in the summertime. The winter intervention on snowmobile with the help of the adapted Beep Mat BM4+ and dynamite helped us efficiently prospect those targets at very low costs. The equipment required for a two-person team was :

• 2 snowmobiles;
• 3 Beep Mats BM4+ including 1 adapted to snowmobiles;
• 1 Pionjar drill;
• 1 drill with specially manufactured steels;
• 24 kg of dynamite;
• 2 electronical navigation systems of GPS type.

The field procedure was realized in two steps. The first one consisted in establishing a road access by snowmobile to reach, with the help of GPS, the targets defined by the compilation, then in finding conductive sites with the help of the adapted Beep Mat BM4+. The second step was to go back to these sites with the blasting gear and to sample.

We were quite surprised at the investigation depth of the adapted Beep Mat BM4+. Indeed, we were able to detect conductors under a cover of 5 to 6 feet of snow and 3 feet of overburden. The standard Beep Mat could not have detected those conductors. Thanks to the success obtained with this prospecting program, we plan on doing other interventions on interesting targets in areas that are hard to access in the summertime.

Sincerely yours,

Re: Use of the Beep Mat in the discovery of the Tortigny deposit

Dear Sir:

As requested, I have the pleasure to briefly describe to you the role played by the Beep Mat tm during surveys that led to the discovery of the Tortigny deposit.

Tortigny is a massive sulfide deposit rich in Cu and Zn. It is located in the Frotet-Troilus greenstone belt, about 100 km north of Chibougamau (Quebec, Canada). In 1995, a drilling campaign defined a near-surface resource (0-200m) of 330,000 t assaying 2,6% Cu, 5,75% Zn and 73g/t Ag.

In 1993, computerized compilation and research works were done and led to the definition of several exploration targets for the discovery of base metals in the Troilus greenstone belt. In the summer of 1994, a four-man geological team, including myself, was mandated to investigate these different targets and to define their potential. As many of these targets were characterized by the presence of INPUT anomalies, it was clear from the beginning that we needed the Beep Mat to correctly evaluate them.

During our first visit in the Tortigny area, it was evident that the INPUT anomalies of the area were caused by an horizon of pyriptic and graphitic argilite. However, we were intrigued by an outcrop next to a swampy zone that looked silicified and seemed to contain some chacopyrite veinlets that caused the Beep Mat to "beep". As we came back to check and prospect the surrounding area, we localized, with a hammer, the first mineralized float that turned out to contain more that 15 % Zn. From then on, we had no more doubts about the usefulness of the Beep Mat tm. It allowed us to localize more than a dozen of massive sulfide floats, rich in Cu and Zn, in the swampy zone. The blocks were covered by moss and by a few centimetres of overburden. They led us directly to the source which was also located by the Beep Mat.

We are currently pursuing our exploration campaign in that greenstone horizon. We hope to find other mineralized showings that will hopefully lead us to an economic-size deposit. For that campaign, we will continue to systematically use Beep Mats.

Yours very truly,

Update note: As of September 1997, the Tortigny deposit is in the stage of a feasibility study for a mine exploitation.
