Overview of Properties
Ontario, Canada, Potter Mine Claims
.
The Potter Property is a group of 28 leased and patented  mineral claims in the prolific mining area of North Eastern Ontario, located in a geologic belt adjacent to the Porcupine Destor Fault.  The rock formations are a structurally complex, highly faulted assembly of volcanics intruded by peridotite, granodiorite, and diabase dykes.  Rocks in the vicinity of the Porcupine Destor Fault are host to numerous mineral showings with several past, present and developing producers of gold, base metal and asbestos.  Access to the Property is on 6 miles of well maintained forest access road branching North off highway 101, 18 miles East of Matheson, Ontario.

From previous mining operations the Property has infrastructure, underground workings, vertical mine shaft 1320 feet deep and 8 mining levels extending approximately 1200 feet westerly from the shaft.  This area of the Property was mined and 478,000 tons processed from 1967 to 1972 with a mill throughput in the latter years of 750 tons per day.  Diamond drilling reported continuation of the sulphides for at least 300 feet below the bottom level.  Working plans of the two bottom levels suggest  a lengthening, widening and grade improvement, particularly in zinc content of the ore zone with depth.  Possible Resources, top opened on the bottom level are 250,000 tons grading 2.66% copper, 3.45% zinc and 0.015 opt. gold.

In April 1996, the company initiated a geophysical program to more accurately define the ore zone along the mined strike length.  This program successfully identified five magnetic anomalies and seven VLF-EM conductors.  In summer 1996, a 5,000 meter shallow drill program tested the conductors flanking the magnetic highs.  Three of seven holes drilled intersected over 70 meters of sulphide mineralization and defined three broad geophysical target areas; 914 meters east of the shaft, 792 meters southeast of the shaft and 1,158 meters north-north-west of the shaft.

Previous mining records indicated that the ore zones were becoming thicker and higher grade with depth. Therefore, following further geophysical work and a thorough review of all drilling data, the company planned the first phase of its deep drilling program.  Holes S97-08A, S97-09 , S97-10, S97-11, S97-12, S98-01, S98-02, S98-03, S98-04, S98-05 and S98-06 were drilled to the west of the shaft and tested the  continuity beneath the bottom 335 meter level.   The continuing deep drilling proved the mineralization is open at depth and along strike with holes S98-05 and S98-06 intercepting very impressive ore zones. The table below details the highlights of results of the Phase 1 drilling program.

Shortly after the deep drilling program began in December 1997, Millstream initiated a real-section induced polarization survey, which yielded some of the most significant geophysical results.  Chargeability contour maps were produced for 300 metres, 600 metres and 900 metres depths for a large area within the vicinity of the shaft.  They clearly identify a large target in the north-west of the previous underground workings that plunges in a west-north-westerly direction, as well as targets to the south, north and east of the shaft.

Seven of the sixteen deep holes drilled on the property have intersected significant widths of high-grade mineralization and confirmed the theory that ore zones below the previous workings are continuous, having both significant widths and grades at depth. These findings certainly show the huge potential of this prospect which is something that has not eluded the attention of the mining media.

With the excellent results of the geophysical survey, the completed drilling programs and the fact that the property hosts known massive sulfide deposits, Millstream intends to explore areas in accordance with the recommendations of its V.P. Mining Edward Bettiol P. Eng. and its consultant geologist David Gamble, and the results of the geophysical survey.

Ontario, Canada, Airport Property
.
Millstream recently obtained an option to earn a 50% interest in 46 mining claims located in Falconbridge Township, Sudbury Mining Division, northern Ontario, Canada. The claims, known as the Airport Property, are located at the eastern edge of the Sudbury structure tied onto the east side of a large group of claims held by Falconbridge Ltd.

Deep seated - high grade mineralization is being explored along this edge of the Sudbury structure to the northwest of the Property. It has been reported that Inco Ltd. at its northeast rim Victor property is exploring a rich nickel, copper and platinum deep deposit having gross in-situ value in excess of US $1,000 per ton. (As referred to by the Globe & Mail, January 25, 1994 and the Northern Miner, October 27, 1997)

Previous exploration on the Airport Property carried out by others resulted in the discovery of sulphide mineralization and low copper, nickel and gold values. The Property is reported to contain anomalies of Cu, Ni-PGM mineralization and areas of gold value. It has Geophysics established conductors with rock types which may host Sudbury type Ni-Cu and gold deposits.

Two major faults cross the Property trending southeast affect all rock units and are known as the Airport Fault and the Norduna Fault. These faults are now filled by olivine diabase dikes and copper-nickel-cobalt-PGM mineralization has been found in association with these faults.

The northwest portion of the Property hosts mafic rocks of the Stobie formation, including basalts, gabbros and norites. Areas of Sudbury Breccia with sulphide mineralization have been observed in the northern part of the Property. Gold geochemistry anomalies have been found in the southwest part of the Property and may represent the extension of the mineralization zones of the Falcon Gold Mine which abuts the Airport Property claims.

Millstream is responsible for funding an exploration expenditure of $550,000 on behalf of the Property by March 31, 1999. Thereafter, Millstream shall be responsible on an equal basis, representing its 50% interest for all further mutually approved progress and funding commitments.

Millstream crews have commenced linecutting to establish a ground control grid over the property. A follow up ground based Magnetometer/ VLF Electromagnetic Survey with an overlapping Max-Min Geophysical survey will commence in the near future.

Results of the current sampling done by Millstream in the northern part of the property have returned the following assays:

Montana, USA Tamarack Property
.
The Tamarack Property its a former producing, high-grade gold operator in the Tobacco Root Mountains, Madison County, Montana consisting of six (6) patented claims and a further unpatented claim block tying all claims contiguous. The Tamarack Property is accessible year round, 4 miles from the town of Sheridan, on the same gravel maintained road leading up to the Uncle Sam Property (a further 6 miles).

The associated assets include a new small 60 to 100 t.p.d. mill erected in the early 1990's and an older small 50 to 60 tpd mill last operated in the 1960's. Additional associated assets are tailings disposal ponds, water supply lagoon and well, compressors, bulldozers, loaders, haulage trucks; underground mining equipment, parts and tools. An electric power transmission line complete with a sub-station on the property can be energized on signing a current contract with the Montana Power Co.

The Tamarack Property was initially discovered in the 1860's and has been worked intermittently, both on surface and underground, up to the present time. The most dedicated undertaking of the property was carried out by Mr. Alexander Leggat, B.S., E.M., a professional mining engineer, from 1927 to 1937. During this period Leggat surveyed and assayed the past workings producing detail plans of the mine and geology. Due to the lack of proper financing he developed and ran the mine on a salvage type operation until he ran out of funds. In his final report dated March 30, 1937, he expressed his findings and conclusions of the ore occurrence and characteristics. Leggat described the occurrence in the Broadgauge ore body of the Tamarack Property, below and above the 406 drift, "having the gold mainly in the limestone above the hanging wall of a large body of intruded porphyry, and the porphyry seems to carry low values for a considerable thickness. The main ore body, however, being the limestone, in which occur irregular pipes, streaks and bunches of a white, siliceous material, rather porous, and not vein quartz but is usually very rich - samples having assayed as high as 27 opt. The gold occurs in the rock absolutely free and very pure."

Millstream’s initial plans for the Tamarack Property are to establish a new surface grid tying in the surface structures, excavations and adit portals. Thereafter, to carry out systematic geophysics surveys to contour the limestone/intrusive contact with follow-up diamond drilling.

The Tamarack agreement allows Millstream to utilize the older mill to process the ore produced from the Uncle Sam Property. Millstream’s plans are to refurbish and up-grade the older mill for this purpose. As previously reported in press releases August 15/97 and September 25/97 an estimated 4500 tons grading 0.44 opt gold from the remnants of the old stopes in the Uncle Sam can be processed for a bulk metallurgical test run. Additional possible mill feed can be obtained by advancing the hanging wall vein drift beyond the old workings.
