LABORATORX WORK.

Saaples were drIed and the1r weights and volumes were determined. The samples were then c~ncentr8ted by means of a laboratory Wilfiey Table, ann the 1'Ieipl.ts and volumes of the dry concentrates were determined. The percentage com1'1os1 tion of 8. composite sample 0 t the concentrates from each bore line was determ1np.d by ~rain count1ng. The quantIties of heavy minerals In the samples, expressed as weight per oent and as "Lbs/Cu. Yd." (Tlounds weight ot beavy mineral concentrate pel' cubic yard or sand) are giveD in Table A at th~ end ot thIs report. The average pprcentage composltjoD ot the heavy minersl concentrate in the area, obtained from the percentage composition at each bore line, weighted for the auant:lty of minl"'ral at the 11n~, is given :tn Table 2. RESULTS. Dist~lbution of ~ea~!inerall The plan accompanylng t is report sows t heavy mineral-bear:Jng sand extends approxima.tely 800 teet inland from the eastern boundary of the area. The deposjt 1s tnterrupted 'hy long narrow barrUl strips which appear to be parallel to the beach line. These barren ~trips have caused the subdiv1sjon of the area into blocks. From Table 1 it may be obs~rved that the tonnage and grade is fljgn1ficantly greater to the west than to the east. This is rather an unusual case as alaost invariably the tonnage und grade 1s great~r to the east,i.e. closer to the beach.

at

QUantIties! Two separate estimates h~ve been made (Tables land 2) of the tonnages of h.eavy m1n~rals, volumes and average thicknesses of m1npral-bear1ng sands and ot overburden, average grade of minerel-bearing sands and tonnages of each of the heavy minerals. The fi«ures of Table 1/300 are based on 8 thickness of mlnpral-bearing sand jn ~Ach borehole wh~ch has a mjnimum average grade or 300 Ib ~. of heavy mineral per cubio yard, while the figures of Table 1/120 are based on a m1n1mum ever age gracie of 120 Ib~. per cublc yard. Quantitle~ of overburden have been included wi tb the mj_neral-bearing sands to ohtain a max:fJlua thickness of "working face" and a m1n1mum thickness ot ovprburden while stll1 maintaining the desired grade. i;nrlHes AVtl1ab~e for '1nlng. AlI this area 1s divlded ln~ ai otmen s, • 1cK are privately owned. H~nce this area can be mined only by agr~ement with the nwncrs.
