after a bit of thought,experience is all i can think of,fullpan.researching mining claims is exactly like any real estate operation.you must be capable of describing land by aliquot portion(se1/4,se1/4,t.32n,r9w,mer.mdm,for example)which at a glance should tell you =40 acres.like learning another language,you must think in that language.thats the hardest part of doing title searches,and once mastered,all else is simple.hoser john is correct,county recorder good starting place,except sometimes the tax assesors office is perequisite,as they can provide parcel numbers,and legal decriptions by the section.and names of owners.when i was flipping real estates i kept a back page of my notebook devoted to the likings of the clerks involved.the gift of gab gets these for you,dove bars,as in chocolate,were very productive for me.not to mention fresh breath,good manners,and uh,non offensive flirting techniques/subtle flattery.helpfull county clerks working days/hours,fresh flowers.they do in seconds,that which takes me hours.buy the $15 blm book,study up on aliquot portion descriptions,land surveyors,re operators can help put you up on game.research techniques/people skills 95% of this game.good luck,and good huntin
