SummaryandConclusions

TheMedicineSpringsprojectofNorthernLightsResources isconsideredbytheauthor tohave veryhighpotentialtohostaCarbonateReplacementDeposit(CRD)ofPb,Zn,Ag.Historicdrillingattheprojectsitebypreviouscompanieshasdefinedasmall,possiblystratabound,resource(350,000tonsofoxidemineralizationaveragingagradeof2.3oz/tonAg).ValuesinPb,Zn,andbaritearealsomentionedinvariousreportswithvaryingvalues.ThehistoricGoldenPipeminehasproducedsmalltonnagesofPb,Zn,AgandbaritefromveinsinasmallundergroundoperationwheredikesofigneousrockwerefoundcuttingthehostlimestoneofthePermianGersterFm.Theexactamountofthetonnageandgradeoftheproductionisnotaccuratelyknown.While therehasbeenmuchdrillingontheprojectbyhistoricoperatorsmuchof thedrillinghasbeentooshallowtodefineanythingmorethanthesmallknownnearsurfaceAgdeposit.Adeeperholenorthoftheknownresource,JS-105,intersectednotablePb,Zn,Agmineralizationandconcealedintrusiverockbuthasnotbeenoffset.Areviewofthesurfacegeologyandlimitedsamplingbytheauthorhasdefinedanareaofveining and alteration similar to what occurs above the known resource over a strike distance ofapproximately2.4km(1.5miles)withawidthofapproximate0.8km(0.5mile).Therecentlycompleteddroneaero-magneticsurveybyNorthernLightsResourceshasoutlinedintrusiveswithinthevicinityoftheknownmineralization,close toHole JS105,andundercover inotheralteredareas.
