This r epor t descr ibes and evaluates the mineral pstential in con.junct ion with fieldwork carried out on the Marmot claim group. Field WQI 'd cc~-~r,isted sf geoff2gical mapping, :r Q*l: i:: and 5~~1 i 1 geuchemical survey5 carried a_tt an August 25-24, 1932 by Andris Kikauka, Dean Webb Cgeofc~gist5) f Jim Burdett, and Pierre Jette <se&echnicians> _

The property is fccated at the head of the south fork of the Mai-mot River, abaut 16 kilometers southeast of Stewalt, B.C. Elevations on the claim group range from 400~-1,500 meters.

The claim55 c an be accer;sed by logging roads that folltsw the Marmck River to Kate Ryan Creek. Dvergrciwn trails fi~llciw the Marmc& River t ci the headwaters where numerrJur, adits and !rsld WVT- k ingc- have been developed. This includes the Marmut Metals CFeach & Worseshcte>, Engineer, Washington, and High-Grade mineral showings;, which 0: cur can the Marmot 1-7 claim grctup. These &@W8ag% /r Firi exposed along a major northwest trending creek gulley that is a parallel offsat of the Ma-m& R. valley trend.

The tcrpogr aphy of the Marmot River is fU-shaped from glacial act is-i. A relatively flat valley GrJttum is contrasted by steep slaps from 4~+-8C10 meters elevation, with moderate to steep sl cspes above BO!:t meters elevation.

The we1 1 mineral ized Stewat-t Comp?ex e:rrtends from Alice #k-m tu the fskut RiVer. Exploration and develupment of major mines in the stewart avea, including Silbak-Premier, Snip, J!rshnny r-luuntain, Anyox, Alice Arm, Granduc, Scottie, Big Missourr i Y Porter-Idaho, Tena.j un SE, and Maple Bay, and new reserves out1 ined at Eskay Creek, Red Mountain, Willoughby, and Sulpherets makr this area is :3ne of Canada's most active mining camps.

The Stewart area has been exploited for minerals since 1'3OcS when the Red Cliff deposit on Lyddrn Creek was mined. Since then, apprcfiximately 100 base and pr ec irkus metal deposits within the Stewart Mining District have been developed.

Tat, a 1 recorded product ion from the Stewart area is 1,'300,000 uunces gcild, .qis f t:,rJO, Q?:to ounces silve.r, and 100, <1!:10, O<@ pcaunds

c~~~pper-lead-zinc. Most of this product ion comet from the famous Silbak-Premier mine which operated frum 1918 ko 1’368. This mine was reactivated i n 1'387 by L-Jestmiri Resources to rixcrver near sur fare bulk tonnage, low-grade gold and silver. Presently the surface re?stlrvEIs are exhausted and Westmin i5 extracting ore from var iuu5 underground levels. Additional ctre has alss been prclduced from the Big Missourri and Ten&on SE deposits.

The unique high-grade, stratif43rm 2--6ii meter wide mac.3 i ve sulphide is c~_~tstand irig i n terms of predicability of its geology and tenor, and its relatively well defined, contact controlled assay boundary.

The Psrter-Idaho mine operated during the 1'320'5 and early 30's

and is located G kilometers north cl f the Malmot claims. P, modest 30 f 1306 tons of ore prt2duced an impressive 2,33&,4S2

Other p*rrJspects in the Marmot River area include Wire Gold, Gold Wedge, Patricia, Fraser Group, Bi-Metallic, and Patricia. These base and preciuus metal showings have been per iodical 1 y explc~red and developed over the past fifty years.
