SUMMARY

To evaluate the potential for a Norilisk-type nickel deposits within the stratigraphy of the Nipigon Bay area, Falconbridge Limited and joint venture partners Canmine Resources Corporation and Red Engine completed a four (4) hole diamond drill program totalling 2541.88 metres.

Three target areas were tested. Hole NB97-02 was positioned approximately 2 kilometres east of the southern tip of Vert Island to explain the large magnetic feature beneath Nipigon Bay. The hole cored Sibley Group sediments followed down hole by a large granite pluton. The granite was non-magnetic for the first 56 metres, however the remaining 147 metres was moderately magnetic (mag. Se. 17 to 20xlO~3 cgs. units) and explains the magnetic anomaly.

Hole NB97-03 and NB97-04 were positioned to test the stratigraphy west of the McEachan Lake Dyke and south of the North Shore Fault. Hole NB97-03 was lost at 105 metres due to poor ground conditions. Hole NB97-04 intersected a thick succession of Sibley Group sediments before intersecting a large mafic sill at the contact with the Archean basement.

Hole NB97-05 was set up to test the stratigraphy east of the McEachan Lake Dyke and south of the North Shore Fault. The hole intersected a thick succession of Sibley Group sediments and then proceeded into a mafic sill/dyke. The hole was lost in the mafic sill/ dyke due to very poor ground conditions.

No significant nickel mineralization was intersected within the drill holes.

CONCLUSION

The following conclusions are based on the 1997 drill program conducted on NipigonBay:

1) Mafic sills were intersected in holes NB97-02 and NB97-04 at the contact zone between the Sibley Group sediments and the Archean basement.

2) A mafic sill l dyke was intersected at the bottom of hole NB97-05, however the bottom contact was not tested due to very poor ground conditions.

3) No Animikie Group sediments were intersected in the four (4) drillholes.

4) No significant nickel mineralization was intersected.

INTRODUCTION

In an effort to evaluate the nickel potential of the Nipigon Bay area, Falconbridge and joint venture partners Canmine Resources Corporation and Red Engine carried out a diamond drill program to test the large magnetic feature beneath Nipigon Bay and to investigate the sedimentary stratigraphy for nickel-bearing sills.

This report summarizes the 1997 winter diamond drill program undertaken by Falconbridge Limited on the Nipigon Bay "License of Occupation" number 14926.

LOCATION. ACCESS AND TOPOGRAPHY

The "License of Occupation" number 14926, encompasses an area of 22,908 hectares over Nipigon Bay. Nipigon Bay is located along the north shore of Lake Superior approximately 100 km east of Thunder Bay, Ontario (Figure 1). Red Rock is located on the north-west shore of the bay, 8 km east of the Trans Canada Highway. The Red Rock marina served as the staging area for all the drilling activity.

Nipigon Bay is approximately 50 km by 15 km with an average water depth of 7 to 10 metres. The presence of St. Ignace Island protects Nipigon Bay from the open waters of Lake Superior allowing the bay to freeze-over during the winter. Average ice thickness at the time of the 1997 drilling operation was 15 inches.

Topography within the area consists of 100 to 150 metre ridges located along the north shore of the bay. The islands in the area generally display flat topography with diabase sills and dykes forming ridges up to 100 to 200 metres in height.

PROPERTY POSITION

The "License of Occupation" number 14926 was issued to Falconbridge Limited on June l, 1994 for a term of 5 years. The license can be renewed for three (3) additional, five (5) year terms. The license covers an area of 22,908 hectares.

PREVIOUS WORK

No previous work has been reported on the area covered by the "License of Occupation" number 14926. Falconbridge Limited became intersected in the area in 1991 at which time a compilation and a regional reconnaissance program was initiated on the Nipigon Plate. Table l summarizes the previous work performed by Falconbridge Limited during the period 1991 through to the present.

REGIONAL GEOLOGY

A prominant magnetic and gravity anomaly can be trace for 2000 km across the central portion of North America from Wisconsin, northeast under Lake Superior and finally curving down through central Michigan (Figure 1). This geophysical feature has been termed the Mid-Continental Rift of North America (MCR). The rifting event occured during the Proterozoic from 1225 m.y. to 1100 m.y. (Davidson, 1982). Figure 4 illustrates the stratigraphy of the Proterozoic Keeweenawan rocks of the MCR system which lie unconformably on top of older metamorphosed Archean rocks.

The Ontario portion of the MCR sytem is centered along the north shore of Lake Superior were east-northeast faults of the west rift, northwest faults of the east rift and north-northwest faults of the Nipigon Embayment all intersect (Figure 2). The area of intersection is one of eight volcanic centers identified by Green (1982).

PROPERTY GEOLOGY

The stratigraphy of the project area excluding Keweenawan intrusive rocks is shown in Figure 4.

The Archean basement is exposed along portions of the north shore of Nipigon Bay and consists of Archean intrusive rocks. At Winston Point (30km to east of Vert Island) a quartz-diorite occurs unconformably beneath the Gunflint Formation. Further west of Winston Point, medium to coarse-grained granite and granite porphyries are exposed (Giguere, 1975).

The Archean basement is unconformably overlain by 2,200 m.y. sediments of the Animikie Group. The Animikie Group sediments outcrop over a distance of 600 kilometres extending from the states of Minnesota and Wisconson to near Pays Plat, Ontario (30 km east of Vert Island). The Aminikie Group consists of the Gunflint and Rove Lake Formations. The Gunflint Formation is approximately 100 metres thick and is composed of a basal conglomerate, chert, ferruginous chert and black shale. The Rove Lake Formation overlies the Gunflint Formation and varies from 500 to 600 metres in thickness (near Thunder Bay). Blake shales hosting pyritic sections form the lower part of the Rove Lake Formation while turbidite related askose and shales form the upper portion. Samples of the Blake shales collected by Falconbridge in 1992 contained up to 4000 ppm sulphur.

The Sibley Group sediments lie unconformably on top of Animikie Group sediments and/or Archean basement. They were deposited roughly 1300 m.y. ago in an arid coastal environment and range in thickness from 300 to 500 metres. The Sibley Group is divided into three formations:

Kama Hill Formation: Siltstone and shale

Rossport Formation: Red dolomite

Pass Lake Formation: Quartz arenite and conglomerate

Rifting commenced in the central portion of North America between 1,200 m.y. and 1,108 m.y. This rifting event resulted in the eruption of the Osler Flood Basalts. Geological mapping by Mcilwaine and Wallace (1976) on Black Bay Peninsula indicates the source of the volcanic is to the southwest. Flow directions noted by Giguere (1975) on St. Ignace Isalnd indicate the vent for the Osler volcanics was to the northwest. This work by Giguere is supportive of an Osler volcanics eruption centre located in the vicinity of the North Shore Fault and the cross-cutting north-westerly faults (ie. McEachean Lake Dyke).

The stratigraphy of the Osler Group consists of a basal conglomerate which is overlain by approximately 3000 metres of basalts with minor rhyolite present at the base and top of the succession. Lightfoot et. al. (1991) divided the Osler Group into three suites which are summarized as follows:

Lower Suite: ~ 800 m thick , augite-olivine porphyritic basalts.

Central Suite: ~ 1200 m thick, aphyric or plagioclase phyric basalts,nickel depleted.

Upper Suite: ~ 700 m thick, aphyric or plagioclase phyric basalts.

1997 DRILL PROGRAM

A drill program was carried out during the period January 5th to March 20th , 1997 on Nipigon Bay. The program commenced with the building of ice pads in early January in order to support the weight of the drill equipment. The diamond drilling operation commenced on January 31 st , 1997.

Midwest Drilling Ltd. based in Winnipeg, Manitoba was contracted to carry out the drill program which consisted of four (4) holes totalling 2541.88 metres.

A total of 125 core samples were collected during the drill program. All samples were sent to TSL Laboratories in Saskatoon, Sackatewan and analyzed for nickel, copper, cobalt and sulphur. Thirty-six (36) of these samples were also analyzed for major oxides and trace elements. Analytical procedures and results are provided in Appendix II. The geochemistry results are also included with the drill log in Appendix III.

Each hole was collared and drilled with NQ rods until "whipping" of the drill strings necessitated the reduction to BQ rods. All holes except hole NB97-03 had to be reduced to BQ core size. Each hole was plugged using a Dutem plug and then capped with 15 metres of cement. The emplacement of the plug and the cement seal prevents cross contamination of lake water with in-hole ground water.

The core was logged in a temporary core shed located in the town of Red Rock, Ontario. At the end of the drill program, all cores were transported to the Ontario Mines core Library in Thunder Bay, for permanent storage.

ENVIRONMENTAL

Throughout the drill program numerous trips to the drill sites were completed by Falconbridge Limited personnel to ensure the sites were kept in a clean and tidy manner. Upon completion of each drill hole a preliminary environmental drill site inspection was carried out. This preliminary site inspections did not identify any major environmental problems. The final site inspections was completed on April 17th , 1997 by representatives from Falconbridge Limited, Bio-Consulting and the O.M.E.E.. This final examination was left until snow conditions on the ice had dissipated to a point that allow a thorough inspection of each drill site. All the remaining debris at the sites was removed and disposed of accordingly. Each site was determined to be in compliance with both Falconbridge's environmental standards and government regulations.

Water and sediment samples from each drill site were collected prior to and after the drilling of each hole. The samples were analyzed for any detectable levels of oil and grease. The water sampling was completed on behalf of Falconbridge Limited by Bio-Consulting from Kakabeka Falls, Ontario. The sampling indicated that the drill activity had minimal impact on the area. A summary report of the results is provided in Appendix V.

PROGRAM RESULTS

A brief description of the drill program results is summarized below. A more detailed description of the drill results can be found in the drill logs in Appendix III. The location of the drill holes are illustrated on Figures 3 and 5. A logistical summary of the drill program is provided in Table 2.

HOLE NB97-02

Drillhole NB97-02 was positioned to test the deep magnetic anomaly, modelled at approximately 1000m depth and located east of the McEachan Lake Dyke and north of the North Shore Fault. The hole was collared approximately 2km east of the southern tip of Vert Island (UTM position 426990E, 5416241N) and drilling due north (OOO 0) at an inclination of -80 0 . The hole reached a final depth of 677.81 metres.

The hole intersected a thick sequence of Sibley Group sediments (22.72 to 475.20 metres) composed of mudstones, siltstones and sandstones. Archean granite was intersected downhole of the Sibley Group sediments. At a hole depth of 469.26 metres a 2.49 metre mafic sill was intersected within the Sibley sediments and just above the Archean unconformity. A fine grained mafic dyke (cross-cutting at 20 0 to core axis) was also intersected within the Sibley sediments between 149.35 to 154.00 metres. Another 0.16 metre mafic intrusive was intersected at a hole depth of 401.98 metre. This mafic intrusive was located within a brecciated zone of Sibley mudstone and siltstone. No sulphide mineralization was observed in these mafic subvolcanic intrusives.

The magnetic anomaly is explained by 2-5 % disseminated magnetite within the granite which was intersected between 531.00 metre and continued to the end of the hole. The average magnetic susceptibility reading from the granite was 17 to 20 x l O"3 cgs units.

Assay samples collected from the mafic intrusions returned no anomalous nickel or copper values.

10

HOLE NB97-03 and 04

Hole NB97-03 was positioned to investigated the stratigraphy south of the North Shore Fault and west of the McEachan Lake Dyke. The hole was drilled due south (ISO 0 ) at an inclination of -80.5 0 . The hole was abandoned at a final depth of 105.00 metres after the rods became stuck in the sand. A decision was made to re-collar the hole from the same set-up but at an inclination of -85.5 0 . The new drillhole was named NB97-04 since core was retrieved from hole NB97-03.

Hole NB97-03 intersected Sibley Group sediments composed of burnt-red to buff coloured sandstone (quartz arenite). No samples were taken in hole NB97-03.

Hole NB97-04 intersected Sibley Group sediments to a depth of 886.85 metres. The sediments were comprised of the same sandstones as hole NB97-03, plus siltstones and mudstones. Downhole of the Sibley sediments a thin interval of altered granite (886.85 to 890.32 metres) was intersected before coring a 57.73 metre thick mafic sill (890.32 to 948.05 metres). The hole ended in a mixed zone of basalt and granite which locally displayed a gneissic appearance with low foliation angles (20 0 to C A). This mixed zone was interpreted to be the Archean basement. The hole was drilled to a final depth of 1015.55 metres.

Assay results from the drillhole returned no significant nickel or copper values.

HOLE NB97-05

Hole NB97-05 was positioned to test the stratigraphy south of the North Shore Fault and east of the McEachan Lake Dyke. The hole was collared to drill due south (OOO 0) at an inclination of -85 0 . The hole reached a depth of 744.15 metres at which point poor ground conditions resulted in the termination of the hole.

The hole intersected Sibley Group sediments composed of burnt red to buff coloured sandstone and siltstone extending from the bottom of the Bay to a hole depth of 708.30 metres. Downhole of the Sibley Group sediments the hole intersected a mafic sill or dyke with the contact not determined because of poor ground conditions. It was at this point the hole was abandoned due to the poor hole conditions.

Assay results from the drillhole returned no significant nickel or copper values.

SAMPLE PREPARATION PROCEDURES

Rock and Core:The entire sample is crushed, riffled and a split ofapproximately 250 grams is pulverized to -150 mesh.

FIRE ASSAY PROCEDURES

Geochem Gold (Au ppb, 30 g)Geochemical gold analysis begins with a fusion using a flux mixture of litharge, soda, borax, silica, 'fluorspar with further oxidants or reductants added as required. The relative concentrations of the fluxing materials are adjusted to suit the type of sample being analyzed. An aliquot of palladium is added as a final collecting agent. The resultant lead button containing precious metals is then cupelled. The precious metals collected in the palladium bead are then dissolved in aqua regia and analyzed by Atomic Absorption Spectrophotometry.

When analyzing for platinum and palladium, an inquart of pure silver is added as a final collecting agent, rather than palladium. The final dilution is a combination of deionized water and a cadmium sulfate solution.

Assay Gold (Au ozt, g/t, 29.16 g)Gravimetric assay analysis begins with a fusion using a flux mixture of litharge, soda, borax, silica, fluorspar with

. further oxidants or reductants added as required. Therelative concentrations of the fluxing materials are adjusted to suit the type of sample being analyzed. An aliquot of silver is added as a final collecting agent. The resultant lead button containing precious metals is then cupelled. The subsequent dore' bead is parted with a dilute nitric acid solution. The gold obtained is decanted with deionized water, dryed, annealed, and weighed on a microbalance.

Whole rock procedure - Silicate Rocks

1. Samples are pulverized to -200 mesh and left to dry overnight in a drying oven at 105 C.

2. A portion of the dried sample is weighed into a previously weighed ceramic crucible and put into a furnace for two hours at 1000 C. After cooling, the crucible and sample is then placed in the 105 C. oven to be later weighed for LOI losses.

3. A 200 mg sample of the dried sample is weighed into a carbon crucible containing flux and mixed thoroughly. This mixture is cured for half an hour and then heated to 1100 C. The hot melt is added to a dilute HNO3 acid solution and stirred for overnight on a rotary shaking tray.

4. The flux acid mixture is diluted with double dionized water and poured into plastic auto-sampler tubes for analysis by ICAP.

2. A 250 mg portion of the sample is weighed into a 125 ml teflon beaker and is wetted with distilled water, to which 10 ml HNO3 and 5 ml HF acid is added. The samples are left uncovered for 10 minutes The beaker is then covered and heated till all red Nitrous fumes are gone. The beaker is removed from the heat and 15 ml of HCL is added. The covered beaker is returned to the heat for a further 15 minutes. The cover is then removed and the solution is slowly brought to dryness.

3. The dried sample is reconstituted with 5 ml HCL and heated gently until salts are dissolved. If any residue remains, an additional S ml HF is added and the sample is then again brought to dryness and brought back with 5 ml HCL.

4. Ten ml of saturated boric acid solution is added to the HCL salt mixture which is the brought to 100 ml volume with distilled water. An aliquot of the solution is poured into plastic auto-sampler tubes for analysis by JCAP.

METHOD 1001-WI

ICAP Whole Rock instrument analysis procedure.

1. After each sample is analyzed, one blank is aspirated through the system to eliminate any carry-over between samples. For every ten samples, one known and one blind standard is analyzed.

2. Calibration of the instrument is achieved by the running of four international rock standards with well established values and one synthetic standard for the trace elements. These standards will have been previously digested using the standard whole rock procedure in triplicate and run to assure precision and accuracy. The synthetic is made by replacing 7 ml of DI water in a blank with 7, l ml aliquots of 1000 ppm of the different metals of interest. Where possible, i f t he type of rock material to be analyzed is known beforehand, SRM' of the same rock type should be run as the standards with these samples.

3. The suite of metals known to cause interferences upon othermetals are run daily and the interference factors stored.Since all elements are automatically background corrected, theblank solutions are run to check for digestion contamination foreach "batch" of samples but not to correct for background intensities.

4 . Recalibration of the instrument is performed when a drift of more than 5 percent occurs. The calibration is verified once every ten samples.

5. One out of every ten samples is repeated. These are usually samples where the combined oxides and LOI does not equal 99.5 !fc -+X- 1.5*. Samples that repeat low, with an overall precision of better than 2V are averaged and reported low to the customer, low totals may result from samples having elements such as sulphur or flourine that are not necessarily reported with the whole rock analysis.

1. Instrument calibration is performed using synthetic solutions in the same final acid matrix as the samples (5* HCL). Standards similar in composition are digested and run along with samples to verify recoveries and accuracy of the calibration. Where recovery of the known standards is less than 95% compared to the synthetic calibration, the digestion of the samples is repeated. All synthetic solutions are obtained from chemical supply companies who certify their solutions from high purity stock materials for use with ICAP.

SANDSTONE

Well bedded, medium grained, burnt red and buffsandstone. Sandstone is welt indurated withrounded mm size quartz grains in weaklypervasive carbonate cement. Interval consists ofalternating burnt red and buff coloured bands (ona mm to cm to dcm scale) with local mm bandswithin the buff coloured portions having a lightgreenish tinge. Red colour is due to the presenceof hematite (Fe-oxide). Buff banding oftencross-cuts the bedding and also commonly formsdiscontinuous bands and spots (1-5cm) possiblyindicating reduction of hematite by acidsolutions. Unit is un-mineralized. Local weakfracture (1-2mm) controled carbonate veinletscrosscut the unit. Unit is locally cross-bedded.

SANDSTONE

Moderately to well-bedded sandstone comprised ofera- to dm-scale rust-red beds (SS-65%)alternating with tan-brown granular beds andspheres (35-45/C). Flame structures and localcross-bedding structures are present. Red colourdue to Fe-oxide staining through oxidation(chemical?). Tan-brown intervals are cm-scalebeds and as mm-scale spheres; rare sphericalstructures nucleated around mm-scale sulphidespecks. Local dm-scale sections of red sandstonealso express a purplish hue (increased Mn-oxidecontent ?). Local mm-scale concordant carbonateveinlets.

PETROGRAPHIC REPORT ON 11 SAMPLES FROM 3 SEPARATE MAFIC SILLS

SUMMARY:This suite of mafic intrusive rocks corner fr.:ifi Uvree sills, th.-.

thinnest (NB97-02) only 1.8 m thick, the thicker ones (NB97-04 and C- about 50 m thick. The thinnest sill is so fine-grained ('.'"'chilled) v. relatively altered that primary composition, and therefore e vi den c..j differentiation, is difficult to evaluate,, It contains 5-10X scattc- rounded ?amygdu-es or '"'altered mafic crystals (l mm in diameter th^t could have b e: en orthopyroxene or '"'olivine (the latter would fit wit',- mineralogy of the thick sill, but cannot be proven); slight variat.!'.'.: from 50X plagioclase to 4OX plagioclase is apparent from top-central the lower margin of the sill.

The thick sill in NB37-04, mainly an ?olivine gabbro, is clear l; graded textural l y from a coarse, pegmatitic texture ab the core to finer, more homogeneous margins; mineralogical variation is less w e j., defined but may indicate differentiation. The estimated original mineralogy ranges from 5 OX calcic plagioclase, 4 O X clinopyroxene an'..: each of r el i c t ? ol i v i n e an d accessor y op a q ue o x i d e s (magnetite, "'ilmenite) at the margins of the sill to 407, zoned labradorite- oligoclase, 45X clinopyroxene, lG-15% relict ?olivine, S-5% opaques the centre of the sill, suggesting some differentiation was present.

The third sill or ?dyke in NB97-05 is distinct in the presence significant K-feldspar (interstitial and possibly primary in the cov uncertain in the margin) and minor biotite (possibly secondary, witl. abundant to minor secondary amphibole). However, a relation to the thick sill is apparent in the possible relict ?olivine found in the core of the body (TS01056). Thus this sill/dyke could be character, as an 'T-'olivine-bearing monzogabbro/monzodiorite. Absence of K-telo-:^ in the thickest sill and presence in the two thinner sills suggest:, that the thinner ones are more differentiated. Also, apparent incrc.- in K-feldspar and opaque content in the lower margin of the first (thinnest) sill may suggest differentiation (although textures inclic. that part of the K-feldspar may be secondary).

Alteration in most samples is significant, bu.u mainly propylite in character (l-iydrobiobite-calcite"chloribeHV-K-f;-:.l.d'.3par in the f:u sill; ser i c i t e/c l ay-gr sen b i ot i t e/hydr ob i ot i t e -c hi or i t e-:V---c al cite, feldspar in the second; amphibole-clay/sericite-biotite in the th.U\..

APPENDIX V

Environmental Assessment

(Pre and Post drilling)

METHODS

Sites l through 5 were located utilizing differential OPS and a certified Ontario land surveyor.

The locations are defined as follows:

Hole l Co-ordinates: 426990E, 5416230N Azimuth: 180

Hole 2 Co-ordinates: 425430E, 5410540N Azimuth: 180

Hole 3 Co-ordinates: 427 HOE, 5411 SOON Azimuth: 180

Hole 4 Co-ordinates: 425770E, 5412760N Azimuth: 180

HoleS Co-ordinates: 419160E, 5408200N Azimuth: 180

Once mobilization of drill rigs was confirmed, and prior to commencement of drilling, the sites

were sampled for detectable limits of oil and grease in both water and sediments. A 10 inch jiffy

power auger was utilized to drill 3 adjacent holes within 10 meters east of each drill site to

accommodate sampling equipment. The east side positioning was selected as water movement/

currents are predominately in this direction. Water samples were collected utilizing a standard

acrylic/synthetic Van Born sampler sub ice level. Sediment samples were taken with a six inch

Ponar bottom dredge. Collected samples were submitted to Tara Scientific Laboratories,

Thunder Bay, for certified analysis. Each site was visually inspected for possible contamination

due to drill pad construction prior to commencement of drilling.

Post drilling samples were taken only from sites that had drilling activity, i.e. Sites l, 2, and 3.

Sample holes were positioned as close to the drill hole as possible on the east side. Sampling

procedures were identical to pre-drilling methods with the exemption of sediments at Site l

(Vert Island). In this case sediment was collected from the mud/rock debris left on ice from

pulling the drill casing.

RESULTS

The results of analysis are attached. See Certificates of Analysis, Tara Scientific Laboratories,

Thunder Bay. The pre drilling analysis indicates oil and grease in sediments were below

detectable limits. Apparent oil and grease in water has been attributed to organic matter

suspended in the water column.

Post drilling analysis of sediment indicates no impact at sites 2 and 3 (bottom sample). At site l,

where residual material on ice was sampled, a finding of 0.12 ppm indicates a detection of oil and

grease, but that it is below an accurate detection limit. Sampling of Sites 2 & 3 occurred as drill

rig demobilization was under way. Conditions at the time were difficult as snow and slush levels

were high. Subsequently, Site l was inaccessible and wasn't sampled til April 17/97, in

conjunction with your site inspection.

The site inspection of April 17/97, once the ice had lifted, indicated an incomplete retrieval of

material from each site, as well as site contamination at sites 2 and 3 of hydrocarbons. The

contamination was likely due to mishaps in fueling procedures. The lack of prior detection was

likely due to conditions at time of demobilization. A positive result of the post-drilling sampling

regime is that the sampling hole acted as a catchment basin for contaminants, facilitating a

successful removal of most remaining material. Remnants of tarping, wood scraps, flagging,

pickets , burlap and wire were attributable to ice conditions at demobilization time and some

faulty housekeeping practices. In all, the program has had minimal impacts. This diligence of

post drilling cleanup of April 17/97, improved the sites dramatically and your efforts are to be

recommended.

RECOMMENDATIONS

1) That sites on ice be inspected after the ice has lifted and prior to breakup.

2) That if slush conditions persist at time of demobilization, composite samples of on ice water about the drill site be collected and retained for analysis of hydrocarbon.

3) That inventory control of materials on site be maintained to ensure retrieval upon demobilization.

4) That caches of hydrocarbon materials on ice be protected from water inundation due to rising slush.

5) That captured material from fueling procedures be removed from sites as soon as possible.

6) That standard housekeeping practices be developed and enforced with contractors.
