Stockholm den 5/ Ingenjör Hofeleth Orkla Grube A/S Lökken-Verk, Norge 11 Hdgt årade Ingenjdr Hofseth, Det var en hdget 1ntressant diskuselon vi hade 1 Stockholm och jag får tacka så mycket fdr de många vädefulla upplyeningar om Ldkkengruvan såväl eom de geologieka detaljer som Ingenjdr Hofseth kunde meddela. Vid detta t111falle lovade jag att skriva vad jag ansåg viktigaet av resultaten vid vår elektromagnet1ska flygprospektering. På den bifogade kartan har jag lagt in de huvudeakl1ga elektriakt lelande zonerna. Jag har numrerat dem med 1,2, 3,4 och 5, vilket skall i någon mån ange deras rangordning. På samma karta har jag med streckade linjer lagt in zoner utmed vilka fdrakjutningar av de elektriaka ledarna tyckas upptrdda. Dessa fdrekjutningezoner kro naturligtvia mycket hypotetiska, men derae låge har markerats på kartan, då de kaneke kunna få betydelse vid forteatta proepekteringearbeten. Beträffande de numrerade ind1kationerna 11gger nr 1 tåmligen djupt, antagligen 4 m eller mera. Ind1-ationerna 2 och 3 tyckae 1nd1kera ledare på etbrre djup. Vissa delar av de långa ledande zonerna 4 och 5 dro etarkt markerade ledare, men derae karaktdr år evår att avgöra. De tycke ligga såvål 1 ytan eom på djupet. Jag hoppas att deeaa emå anmarkningar kunna tjana som ledning vid forteatta prospekteringearbeten och borrningar. Jag behdver nog mera tid fdr att ingående etudera Liikken-strukturerna och jag hoppas att det skall bli tillfälls litet lingre fram att få beadka gruvorna och forteatta våra 1ntrelleanta diskuse1oner. Med h.järtliga häleningar och utmårkt hdgaktning Hans Lundberg

Gentlemens Referringto your lettera of tle 16th of Februaryand the 3th of Mardh,we send you herewithmap showinganomalyreoordingson Linee 2 to 13, both north and south of the cable, as you requested. On this map I also show my interpretationof the anomaliesthat cannot be accountedfor from known artificialconductors. It is no eurpriseto me that in the ground aurveysthey do not obtain the same anomaliesas we recorded in the airbornesurveye. As I alreadywrote you on March 24th, the effects from the ground itaelf many timee overehadow-the weaker anomaliesthat are obtained from conductorsat greaterdepth. May I suggestthat a test be made by usingthe ore as the one electrodeand stretch cable from the ehaft along Line 1 or 9 some 1 to 15 kilometersnorth-westfrom ths mine and there make groundingthat is suf f icientlygood so that the cable could carry 4 to 5 amperes. If this ie correotlymade, and the ore body exists at the depth of soms 4 metres, as we expect, profilesobservedacross the anomaly outlinedby me shouldbe possibleto oonfirmby ground surveys,keeping in mind that euch profilesshouldextend at lecat 3 kilometerson each side of the anomaly. Yours very truly, rew Hans Lundberg

A cable 7.() wat fcst Taid out (July 9th - llth parallell tu and south of the knovn ore-zune. The pcsition of the cable (vhich vas gr)')unded at bdth enis) is 'wn on the attached :napa.

On the secund map the effects of the»nuwn artifictal conductcre have been eltminated ao that this map should show only anomalies caused by geological featurea, mineralized zones or ore-budie.;. Certain complicatiuns naturully where encounted in veeding out the effects of the artificial conductors near the mtre but it is hoped that the anomalies left here reasunably well corresp_nl ti ore left in the mine Without knowing anythtn)3 of the general or lucal geology an interpretation uf the result is rather diffienit. It is theref.jre aug;ested..hat after the maps have been studied a meeting be arranged for between the companys geologist anl the writer ;before "flc.t.-jber 6th when the writer returns to Canala:. Å few points ight be mentioned as a start. According to our interpretation the ore body being mined should extend at dephts in a northwesterly directiun fullowing a couree bent towards north. '2hie course is difficult to comprehend unless the general dip of the flrmation flattens out towards the north.
