jim straight 187 Posted March 29, 2013 Author Share Posted March 29, 2013 Here it is... Marcn 29.... Before I try to answer Dakota Slims question on another postlater today... I have a heart filled Thanks I most try to express:It is friends like Bill Southern that are a rare to find... Over the years Bill has been one of thebest, most kind, and one of the most understanding individuals that are out there. Through my lack of computer skills, Bill without my knowledge or asking fixed my glitchso I could again be able to access this forum... Then again he added the photo of meso I'm no longer just a shadow... I do not even know where the photo came from. ButI'm standing at the back of my 1979 Ford 150 4-wheel drive truck with a camper shell.Somehow I believe years ago I may have seen Bill in a similar rig while out in the Rattlesnake/McClure area... Could it be? However, I briefly met Bill while at GPAAouting near Rich Hill....But to get to the point of what I'm trying to say: Bill.... Thank You for opening a newdoor for me with this "Jim Straight here." Like me I know you will slog on... But withyour abiility and strength you will through your leadership continue to make a positive andeverlasting impact on all of us who are fortunate be on this forum...

jim straight 187 Posted March 30, 2013 Author Share Posted March 30, 2013 Okay Dakota Slim... Yep Rademacher is in my back yard... However it is an old district dating back tothe finding of hardrock gold at the Yellow Aster. Thus, the Rademacher itchy feet prospectors shiftedtheir interest to the Rand District. But to answer your question Dibblee, Troxel and Morton have briefly refered to it. However I have found only one reference to Rademacher--- it is vague and does not mentionplacer (but 200 ft hardrock shafts and 1500 ft shaft S1/4 sec 29~T27S R40E MDM 5mi. SSW of Ridgecrest), ... page 180 Calif. Div. of Mines and Geology~~~ Mines and Mineral Resources of Kern CountyCalifornia... County Report 1... Troxel and Morton 1962... However I do know other minerals then goldhave been found in the District which is said to be about 50 sq/miles.Try a search engine re Rademacher and you will find more info...However I know about 10 or more years ago at Barnes & Noble there was a large 330 page book:Geolgical Evolution of the Mojave Desert and SW Basin... it had info on the geology a larger areawhich included the Rademacher district. But I feel that there are many other areas with morepotentual, so I'm not Bullish on Rademacher... it is on the northside of the Garlock fault and myinterest more on the southside. I could add more, but I'm a slow hunt and peck two finger typest andon slow dialup... I would like to meet you sometime around Randsburg. You seem to be interested inlesser known areas... My Best... jim Quote Link to post Share on other sites
jim straight 187 Posted March 30, 2013 Author Share Posted March 30, 2013 Whoops getting old...more than one shaft... the deepest is a 250 ft shaft and thelongest drift is 1500 ft... but I wonder if is a crosscut between shafts instead of a drift...This refernce is vague and dates back to 1957... sorry... jim Quote Link to post Share on other sites
Dakota Slim 1,067 Posted March 30, 2013 Share Posted March 30, 2013 Hi Jim. Thank you. I have an interest in all old mining areas and would love to meet up with you. I'll be in the Randsburg area for the next couple of weeks. I'll send you a PM. Quote Link to post Share on other sites

jim straight 187 Posted March 31, 2013 Author Share Posted March 31, 2013 WOW... Rimshot ol' Buddy... You tracked me down... I did not know this. As I remember Gloriatook the photo. I just returned from a week in Nevada and Gloria had me pose for it. Gosh, Ibelieve I was holding my Garrett Infinum. Your "hehe!" sounds sorta Devil'ish...

Rimshot 181 Posted March 31, 2013 Share Posted March 31, 2013 (edited) Okie dokie. lol! You really look good in this picture. How did you like the infinium Jim? Has it got any depth to it?I'd like to know the pros and cons about it....I been thinking... Edited March 31, 2013 by Rimshot Quote Link to post Share on other sites
jim straight 187 Posted April 2, 2013 Author Share Posted April 2, 2013 I barely remember Gloria taking this photo. I'm standing behind my 1979 4-wheel driveF-150 with a camper shell. I remember the occasion as I had returned from spendinga week in Northern Nevada detecting pushes at Oakie Jims Lunker Hill propertryabove Imlay, The nugget is about 105 grains and I found it "out of the channel" on theedge of the push. It was only about 5-inches into what was in late afternoon now ahard sundried clay.... I had to carefully chisle it out. Oakie and cat-skinner Tim Dale followed through the next morning and were back in the channel... I named it Bella'sNugget as I found on the day she was born April 10 2002. I wrote an article and it wasaccepted and published in the ICMJ.... This photo was not used and I'm surprisedto see it as you know this is the same photo the Bill found and posted as my photo.There is a similar photo of me taken by Gloria. However it is black & white was it used inthe January 2004 in Eastern & Western Treasure Magazine... my Free-lance field test ofthe Minelab Eureka Gold.I still have my Garrett Infinium... Up to recently I used it at the California beaches. I hopeto be able to do this again. Also I hope to again be able to write free-lance field tests forW&E again... But this is doubtful due to Ostoarthritus... However while doors close otherdoors open. So rim ol' friend i have misplaced your home address but would like to mailyou some inrormation you might enjoy... jim Quote Link to post Share on other sites
Rimshot 181 Posted April 2, 2013 Share Posted April 2, 2013 I found that photo googling jim straight. Where all the pictures are. I think. I will send you a pm. lol i didn't even see the nugget. Nice one Jim!Rim Quote Link to post Share on other sites

jim straight 187 Posted April 12, 2013 Author Share Posted April 12, 2013 Howdy Rim. I have been having some minor problems but here I be... But for the life of me I have little to say.But I will mention that the Carlin-type "micron-gold" technology in bulk mining Heap Leaching process inNevada is now going full bore... Now I have a question: Anyone on Bills forums wish to update us on whatshappening? As just one example a Hiachi hall truck can now carry 335 tons and a Caterpiller loader can becontrolled via a computer in a trailer! Wow..... Quote Link to post Share on other sites
Red_desert 141 Posted April 16, 2013 Share Posted April 16, 2013 Not to change the subject too much, but now that it has been explained to me. Anyone have experience with IR satellite in the narrow bandwith range, to locate alteration and erosion zones? I'm not asking for more info, a retired PH D scientist explained it well enough to me (can get so technical, don't want to even try posting info on this subject). Only certain narrow band IR satellites will work for gold prospecting, then all the settings have to be perfect. There is some kind of a handbook for using the technology.Some places the BLM had checked by geologists who found nothing, now have alteration zones showing up on these images. There is supposed to be Gossans below surface which had never been found also. A single vein won't show up, but you can locate the other geological factors. I think micron gold on the surface might be located also, is highly reflective. Interesting, public areas with a lot of junk in the ground can show up in a search, works better for remote areas.

jim straight 187 Posted April 19, 2013 Author Share Posted April 19, 2013 Red_desert... Hey you are on target... gossans and surface epithermal gold-electrum-silver hardrock and associatedplacers are now being found to be overlying Carlin-type micron gold at depth... this is why I mentioned the large tonnageequipment in my last post... Back in about 2002 I became suddenly and accidentally involved in gossan gold... 60%gold small wires in a "ferric" matric. We were surface metal detecting on a steep hillside somewhere in Nevada... this isall I can say... but we did not do anything illegal... I'm listening and I'm sure others are also... and this is how we all learn"Tailgate" jim Quote Link to post Share on other sites
Red_desert 141 Posted April 19, 2013 Share Posted April 19, 2013 (edited) Thanks Jim! Besides thin eroded veins (alteration plus erosion zones), gossans, micron surface gold, the thick veins which don't produce placers, some scientists are leaning how to locate them also.There is a science to it, people for years looked for the Lost Dutchman Mine, yet the popular search area has been all wrong.Only one alteration zone in the Superstition mountains where gold can exist. I think a lot of people have it right now, too far and dangerous to get back there. Anyway, the edge of the alteration zone geology is where a scientist would search on the LDM.

jim straight 187 Posted April 27, 2013 Author Share Posted April 27, 2013 Changing the subject... there is a GMT for sale on a the sub-forum. The GMT came out about 2001 and Larry Sallee wrote a great field test on it that was published in early 2002 in Western & Eastern Treasures. To add more the GMT has one of the first updated "Dave Johnon 'follow the magnetic black sand'" readings to display the amount of magnetic susceptibility of the soil... also the GMT has the ability to measure the phase readings (ground balance number) indicating the type of ground that could be associated with higher concentrations of magnentic balck sand... Years ago, the earlier prospectors offset the ground balance of a VLF/TR type detector to listen to the ground noise associated with heavier concentations of magnetic black sand that "could be" due to specific gravity associated with placer gold... but it needed to be within a metallogenetic area that carried place gold such as the volcanic areas associated with epithermal precious metal hardrock ores and associated placers. Just my early mornint thoughts to pass on for good or bad discussion. I'm leaving in a moment to pariciapate in a seeded coin hunt in Pearblossom. Will use a cane and maybe even a walker but "we must push on" as life is Good... Quote Link to post Share on other sites

jim straight 187 Posted April 28, 2013 Author Share Posted April 28, 2013 Howdy Jim... In my last post I mentioned I was going to a seeded hunt in Pearblossom. Jim was there too. He has a Gold Bug Pro ands uses the 11- inch open spoke DD, and I glanced at him during the hunt... and can Jim ever make his Machine make a happy tune: "coin, coin, coin." As for me I got the award for being the oldest participant in the event. But I will say I went the distance as far as time and I sorta forgot to use my cane and as it was metal I started to drag it behind as I detected. Now I will go to the heart of the subject regarding determining the amount of magnetic susceptibility of the soil and also the phase readings (ground balance) indicating the type of soil that could be associated with the higher concentations of magnetic black sand that in a metallogenetic precious mining districts [that are associated as an example] with the epithermal Pliocene-Miocene volcanics. This is how we all learn and I ask to learn more as what little I know is dated... and I'm listening. ("tailgate" as I'm known among the oldtimers in northern Nevada; anyone out there?)

Hoser John 1,240 Posted April 28, 2013 Share Posted April 28, 2013 Glad to hear your still out there a swingn' Jim.

jim straight 187 Posted April 28, 2013 Author Share Posted April 28, 2013 Hoser Ol' Friend... Over the many years I have learned much from you regarding the PESC drywasher.. certinly aheas of it's time. I'm glad that you are going to Monteray... Don't become distracted regarding the "beach things" and miss finding jewelry items lost in the sand while using your Tesoro. LOL... Let us know if you find good things and don't get sunburned... malignant melonoma is not to be taken lightly... Off the subject, but I will post here. I used a search engine and posted "relation ship of carlin-type ane epithermal" Many results were posted. WOW, one was about page 4 on this sub forum... It is "Jim Straight here - Page 4 - Gold Nugget Shooting Forum... Some of you are now quoted... thanks for writing quality information... and again... THANKS Bill for vehicle to make this happen.

jim straight 187 Posted April 28, 2013 Author Share Posted April 28, 2013 Howdy all of you who are out their in the the 'hinderland.' I posted the question: "relationship of carin-type and epithermal" and this is what is now posted as "Web Search Results" and this is my reply... What will now happen? jim Quote Link to post Share on other sites
jim straight 187 Posted May 1, 2013 Author Share Posted May 1, 2013 Howdy all... I have been interested in the relationship of epithermal and Carlin-type precious metal hard rock and associated placers for years and actually my book "ADVANCED" as first published in April 1996 with information regarding usung metal- detectors to locate and work two shallow epithermal hard rock and their assciated placers in the Rochester Mining District. At this time I just added this information as a mini-booklet to my now out of print "Nuggetshooting Dryplacer Areas" with the suptitle of "follow the drywashers." This mini-phamplet in now the heart of "ADVANCED" and docments the finding of two shallow veins using the original Gold Bug and Goldmaster II in Limerick Basin. The phamplet became a popular read with the fulltimers in Nevada after 19 years it has been revised and updated as the latest "September 2010 edition" with an appendix on meterorites. More later as I'm on slow dialup and a two fingered typest and as such in danger of being timed out... tailgate Quote Link to post Share on other sites
jim straight 187 Posted May 1, 2013 Author Share Posted May 1, 2013 Okay the above post went okay. (By the way the pamplet documents<br />finding the two shallow veins in July 1994 and this is where I<br />first met George Duffy Jr. one of the best pocket hunters that<br />I have been privalaged to know). I wrote a article regarding George's<br />exeptional skills... (ref. Picks & Pans: ICMJ Vol. 74; Nov. 1 2004).<br /><br />More for now.. My main interest is regarding the association of<br />epithermal suface deposits and the Carlin-type at depth.

Rimshot 181 Posted May 2, 2013 Share Posted May 2, 2013 (edited) Geophysical maps of northern Nevada reveal at least three and possibly six large-scale arcuate features, one of which corresponds to the northern Nevada rift that possibly extends more than 1,000 km from the Oregon-Idaho border to southern Nevada. These features may reflect deep discontinuities within the earth’s crust, possibly related to the impact of the Yellowstone hot spot. Because mid-Miocene epithermal gold deposits have been shown to correlate with the northern Nevada rift, we investigate the association of other epithermal gold deposits to other similar arcuate features in northern Nevada. Mid-Miocene and younger epithermal gold-silver deposits also occur along two prominent aeromagnetic anomalies west of the northern Nevada rift. Here, we speculate that mid-Miocene deposits formed along deep fractures in association with mid-Miocene rift-related magmatism and that younger deposits preferentially followed these preexisting features. Statistical analysis of the proximity of epithermal gold deposits to these features suggests that epithermal gold deposits in northern Nevada are spatially associated with large-scale crustal features interpreted from geophysical data.http://econgeol.geoscienceworld.org/content/97/1/3.abstractThat's pretty interesting Jim.......hmmmm....

jim straight 187 Posted May 2, 2013 Author Share Posted May 2, 2013 Rim you are in the groove... Can you access "The Tuscarora Au Ag dirstrict; Eocene volcanic - hosted epithermal deposits in the Carlin gold region Nevada" ?authors: Caster, Borden, Henry, Cline, Hofstra, McIntosh, Tosdal, Woodenyear; 2003journal title: Economic Geologyvol: 98issue: 2language: EnglishISSN: 03610128number of pages: 28start page: 339end page: 366Both print and online versions are not available... However there is an Abstract available and itis a pretty good read, But I'm unable to add it to the forum... Hope you or some can. Thisexample is interesting as the vaiues are related to intrusive Eocene volcanic dacite...Most are Miocene or Eocene volcanics related to volcanic trachyte and andesites. But there arealso a few Jurrasic that are related to rhyolite... Rhyolite and dacite are acedic and contain free quartzwhereas the trachyte and andesites are saturated and contain no free quartz...
