    SUMMARY

    The project area was visited in early November of 2007. Addition prospecting was conductedmainly along the access roads and photos taken of some of the stone types for further reference.A number of outcrops were closely examined to compare fracturing vs weathering to determine ifthe material might be suitable for dimension stone and or craft material. While some of the materialwas found to be fractured it is believed that much of the appearance attributed to fractures is actuallya weathering feature.

    INTRODUCTION

    This report covers mineral licence11549M located just west of Deer Lake on NTS map sheet 12H/4(Figure 1) Mineral licence 11549M which consists of 6 claims was staked to cover an area ofmarble which forms part of the Pyes Ridge Marble Deposit. While the area is consideredprospective for marble as a dimension stone, recent staking in the area is the result of an increasein exploration for Uranium.

    LOCATION AND ACCESS

    The claim block lies approximately 2km north of Deer Lake approximately 9 km west of the townof Deer Lake (Figure 2) . It sits atop of a prominent area of high ground known as Pyes Ridge. Itcan be accessed by forest resource roads which leave the Northern Peninsula Highway just north ofNicholsville. One of these roads bisects the property and a series of skidder trails allows access byATV to essentially all of the property. (Figure 3) Some of these skidder trails have begun to growover and are not passable with the ATV.

    PHYSIOGRAPHY

    The area is wooded but has been logged over to some degree. The property sits atop of the ridgeand streams have incised narrow valleys. A prominent valley occupies the southern end of theproperty.Overburden is ubiquitous but outcrop can be found in the form of small bluffs or in stream beds andin areas that were stripped during previous work.

    PROPERTY SUMMARY AND LICENCE STATUS

    The licence comprises a total of 6 claims. These claims which are in good standing were staked inthe late fall of 2005.

    PREVIOUS WORK ( Modified from MODS data)

    The area was extensively explored during the 1991/92 work period with a detailed mappingprogram being completed by Newfoundland Department of Mines Geologist, Ian Knight. Furtherdetailed geological investigations were also conducted by representatives of Technostone and theQuarries Group, two leading Italian Marble companies. Their surveys also included extraction ofsmall blocks, generally less than 0.5 meters square, representative of the various colours which aretypical of the deposit. These blocks were examined in order to determine fracturing, chromaticdispersion, hardness and polishing features. Several sites of pink, pink-green, grey and blue-greenmarble were selected for core drilling to test the vertical extent and fracture/joint patterns of themore attractive marbles. This phase of the work program was supported by the original propertyholder Mr. Len Pye, who provided logistical and labour support.

    In addition to these work programs Mr. Pye carried out extensive field investigations during mostof the work period. These investigations included stripping, block removal and transportation tovarious Canadian and American processing and marketing interests. He also conducted regionalsurveys to determine the extent of the marble deposit and to identify the range of the chromaticdispersion.

    The 1992/93 work program on the Goose Arm Marble Deposit consisted of a continuation ofextensive exploration activities, aimed at identifying areas with dimension stone potential. Theprimary activities included prospecting, stripping, diamond hole drilling, and sample extraction.Extensive work was performed to open quarry faces so that large sample blocks could be extractedfor testing versus ASTM standards and for cutting into slabs and tiles for market testing (Burke andHodge, 1993).

    In 1994 work on the prospect came to a halt, primarily due to the shortage of capital. No furtherwork has been reported on the property since.

    The project area contains two known showings from this work, these being Pyes Ridge White # 1located in the center of the property (figure 4) and Pyes Ridge Blue Grey Banded #3 located in thenortheast corner.

    GEOLOGY

    REGIONAL GEOLOGY (From Mods Data)

    Pye's Ridge is underlain by a succession of dolomite and calcareous marble. It is a polydeformedsuccession featuring metamorphosed Middle Cambrian to Middle Ordovician carbonates. Thesuccession includes rocks correlated with the Hawke Bay Formation, Reluctant Head Formation,and the Port au Port, St. George, Table Head and Goose Tickle groups. The marbles are juxtaposed

    structurally against psammitic and pelitic rocks of the Old Man Pond Allochthon to the northwest,and are overlain, unconformably, by flat lying Carboniferous sediments in the south (Knight, 1992).

    The rocks of Pye's Ridge are polydeformed and are probably part of a duplex. The three main phasesof deformation include: 1) northwest-verging thrusting, 2) northeast-trending, southeast vergingfolding and 3) northwest-verging normal extension. These phases all predate the formation ofCarboniferous cave deposits (red sediment and speleothems) along the northwestern terrainboundary and D2 faults. Locally, reactivation of faults has deformed the speleothems; C-S fabricsindicate sinistral movement. Rare kink bands may correlate with this late or post-Carboniferousmovement (Knight, 1992).

    LOCAL GEOLOGY

    The claim block is underlain primarily by the Pyes Ridge Marble. Outcrops weather a buff- browncolor and occur as small bluffs or as low flat exposures (figure 5) Weathering is preferential alongany banding that is present.

    CURRENT PROGRAM

    The current program consisted of a property visit the first week of November in 2007. Also,samples of marble taken the previous year were examined for carving stone potential.

    WORK DONE

    A total of 4 days was spent accessing and prospecting the area. This included two days travel andtwo days in the field. Heavy flurries cut the second day short with about 2 cm of snow covering theground by 11 am. Work was conducted from the Driftwood Lodge in Deer Lake.

    Work consisted of prospecting and having a relatively close look at a number of exposures createdby previous stripping activity.

    RESULTS

    A number of outcrops on the property show the effects of frost activity with frost action causingpartings along foliation planes. This could be due to the presence of micaceous layers or graphitelayers which would allow water to penetrate the surface. (Figure 6 and Figure 7) It is suspectedthat such fractures would disappear once below the frost line.

    Figure 8 Pyes Ridge White # 1

    Figure 7 Weathering on foliation planes.

    Color varied from outcrop to outcrop but the outcrops observed were of considerable distance apartie. > 200 meters. Figure 8 is a photo from the Pyes Ridge White # 1 showing. This material wasquite white on a fresh surface and appeared to be suitable for sculpting. Once again howevermaterial would have to be obtained from below the frost line.

    Figure 9 Pyes Ridge Blue-Grey#3

    Figure 10 Variation of Blue-Grey marble.

    Figure 9 shows an outcrop at Pyes Ridge Blue-Grey #3. This exposure was massive and showedlittle evidence of fractures or foliation related weathering. A second outcrop about 200 meters upslope from that outcrop was located in an area that had been stripped. Figure 10 shows the exposedsurface of that outcrop. It appeared to be massive and it is believed that a fresh cut surface of thismaterial would be very interesting in appearance.

    Figure 11 Red marble at south end of property.

    Down slope, in the south central section of the property, outcrops of red marble were observed in apreviously stripped area. (Figure 11) This material showed an interesting tectonic breccia textureand although exhibiting evidence of frost action, might be massive at depth.

    CONCLUSIONS AND RECOMMEDATIONS

    A variety of colors were found on the property. At a glance, much of the material which appearsfractured is probably massive below the frost line. More work is required to assess the area for itsdimension stone potential. This would include some shallow drill holes in areas not previouslydrilled.

    Plans for the summer of 2008 include going back into the area with a chop saw and splitting someof the larger blocks on the surface to properly test the material for use as a carving stone. Thisinvolves getting into fresh material that has not been affected by weathering.

    Preliminary results indicate that the material is suitable for craft and carving purposes. Further testsshould be conducted in this regard.
