Great Hill cobalt mines, Cobalt, East Hampton, Middlesex Co., Connecticut, USA

I would like to add here that any assays or ore evaluations on this deposit are contigent upon sampling; the assays on "high-grade" samples will certainly be predjudiced, so those registering values of 6 ounces per ton do not reflect the actual amount of rock required to recover say, a vein of ore an inch or even a foot wide...Sampling techniques can effect results in such a way as to render them innaccurate.....I have worked for many companies that were searching for gold, and by entering such predjudices in the process would render all my work worthless, even though I have been asked by bosses to recover high grade!

I have also been to the Connecticut cobalt locality; given what I have seen, the deposit couldn't yield a large amount of ore.

William C. (CHRIS) van Laer: "I'm using the chicken to measure it..."

Table 20 of Chomiak's thesis does show much less gold in the in-situ vein than in the loose, "discovery" boulder. But the sampling she did was extremely limited, assessing the gold production potential was not her goal.

With apologies to Patti Page; “Is that all there is?” One table, in one unpublished thesis; “Is that all there is?” Where are the follow-ups, the additional assays, rebuttals, clarifications; “Is that all there is?”

Maybe the goal of Table 20 was not to assess the gold production potential of Winthrop’s lode, but it does not seem that the authors minded being credited with finding 6 oz gold. The NYT article, The Hartford Current article, and dozens of rehashes in lesser rags, have never been explained, retracted, or clarified.

In Table 20, the BS samples (Boulder Samples) are well correlated to one another as are the VIS samples (Vein In Situ). There is no correlation (r = -0.012) between BS and VIS, i.e., there is nothing in Table 20 to suggest that BS and VIS are from the same population. The BS samples, like alluvial gold, are not in situ; they could have come from anywhere.

In the VIS samples, the Au has dropped from 6 oz ore to less than eight dwt. Bismuth dives by a factor of 28 (31.5 ppm vs. 905 ppm). Barium jumps around 2000% from BS to VIS. While these elements and proportions thereof are perfectly possible in an ore, the same result might be obtained by mixing Coney Island beach sand with filings from a 17th century Magyar earring.

Hopefully, not being that familiar with Mindat, there will be a table attached showing the analysis data set and a correlation matrix. The data set is from an OCR of Table 20 as provided by Moritz. I corrected the OCR errors, typos, and mistakes using my own judgment.

Perhaps this whole thing will be settled when I go to Storrs. I sincerely hope to be made a fool by what I find. Maybe the full text, along with the thin (polished?) sections, will accomplish this.

Here is a copy of page 1 of Morrill's "Mineral Guide to New England". At the bottom of the page, it shows "© 1963 by Philip Morrill". How long does a copyright last?

In this case it would depend if the copyright was renewed. If it was not renewed it would be in public domain. If it was renewed, it would go public domain in 2058.

I will send a free copy of page 37 of Morill's book which has the map and description of Cobalt, CT to anyone who sends me a Self Addressed Stamped Envelope.

I think it constitutes free loss leader advertising for the heirs of Philip Morrill should they wish to re-publish..

I still want a piece of sulfide, antimonide, arsenide "high grade" from the district, and I will buy it.

"Gold means significant gold." (from an old posting in this thread)

Can you define "significant" in a scientific way? Thanks.

Hi Bart:
FYI, the book is available for $6.95 at [barilbooks.com]

Uwe,

Vielen Dank für Ihre Frage. Ich weiß nicht, die offizielle Zahl für eine Anomalie in Bezug auf Gold. Allerdings, ist in diesem Fall, bin ich der Chef und hier ist mein Denken. Wenn die Fülle von Gold in der Erdkruste liegt zwischen 1 ppb und 4 ppb, so liegt die Mittelwert könnten rund 2,75 ppb und die Standardabweichung etwa 1,5 ppb werden. Angesichts dieser, ein anomolis Werte würde, würde bei etwa drei Mal starten die Standardabweichung, könnte man verwenden 5 ppb. Noranda ist, sind Erzvorkommen mehr als drei Milliarden Tonnen mit einem Mittelwert Gehalt von 0,029 oz / t oder 873,48 ppb. Lassen Sie uns sagen, 875 ppb. Ich erkläre: "Signifikante Gold" liegt zwischen 5 ppb und 875 ppb. Aber, ich bin der Richter in diesem Prozess, und die genaue Zahl ist meine Wahl.

Ich war in Wien im vergangenen Frühjahr. Es ist eine schöne, aber sehr teure Stadt.

I quit. I have other fish to fry. If anybody can provide an assay that indicates that significant gold can be found in CT, please contact me through my regular email. topstone59@yahoo.com. I hope all of you have happy solstice celebrations.
