Thank you Z! Hope so
For those who arenât aware, Dr. Richard H Sillitoe is the foremost authority on copper porphyry deposits in the world, so much so he has a geological model named after him.
His work is consistently referenced in just about every geological abstract or technical report on copper porphyries.
You donât contract someone of his caliber unless you are serious and that the deposit has the potential. This is a very significant announcement for the advancement of the ADL and his analysis will go a long way to furthering the credibility of the ADL deposit/district. This was an excellent move by Auryn and I look forward to reading Dr. Sillitoeâs analysis.

I donât believe it! This guy literally wrote the book on porphyry deposits. He was my go to source of info about Chile mineral deposits from day 1 going all the way back to the 1990âs. Iâm sure he will absolutely love the AltoâŠI am going to guess that they will some comments from him in their IPO promotional literature.

Mike, your thoughts as to why Auryn would employ a geologist of this caliber to report âfor internal purposesâ? I thought Janna was currently the go to guy.
Auryn are moving pretty quickly and they would need a NI 43-101 for an IPO or JV wouldnât they? Could this report have a dual purpose?

Probably just like everyone else who has looked at the property, Auryn is struggling to get a handle on the shear size, scope and nature of the gold/copper deposit so they can develop a sensible plan to exploit it with the limited resources they have available. How do you get the most bang for your exploration buck?
Auryn is small Company. IMO, this project would even be a challenge for a consortium of some of largest Majors out there.

An NI 43-101 would only be necessary if Auryn was going to be listed on a Canadian exchange. Thus far Auryn has only indicated that they will be going public on the OTC. Based on the release, Dr. Sillitoe is only providing an evaluation report. That wouldnât be anything included in a formal geological report as far as I know. As Mike indicated, they could certainly use his findings in corporate literature about the ADL, but as it stands now he has been hired for internal purposes to âprovide Aurynâs team with a fuller understanding of the diverse geological structures found at the Altos de Lipangue and help place them within an historical regional context.â

Here is a whole publication dedicated to Dr. Sillitoe and his work and is worth a read:
The decision by Rio Tinto Exploration to support a Society of
Economic Geologists (SEG) volume dedicated to Dick Sillitoe
is in recognition and appreciation of his contributions to
the understanding of the worldâs major copper districts on
behalf of thousands of industry and academic geologists. It is
fitting that this is done through the SEG, the Society that has
been so closely associated with many of his best known publications.
Dick has been widely honored throughout his career. His
many awards in economic geology include the SEG Lindgren
Award (1975), Wollaston Fund from the Geological Society
(1977), SEG Thayer Lindsley Lecturer (1988), SEG Distinguished
Lecturer (1992), Haddon Forrester King Medal
from the Australian Academy of Science (1995), William
Smith Medal from the Geological Society (1996), SEG Silver
Medal (2002), Sir Julius Wernher Memorial Lecturer for the
Institute of Materials, Minerals and Mining (2008), SEG International
Exchange Lecturer (2012), and Herbert Thomas
Prize from the Geological Society of Chile (2012).
From a start with the UK Ministry of Overseas Development
studying supergene enrichment of copper deposits in
Chile, from 1965 to 1968, Dick then spent three years with
the Instituto de Investigaciones GeolĂłgicas (Chilean Geological
Survey) studying porphyry copper deposits before becoming
an independent geologic consultant in 1971.
Since 1968, Dick has published 120 technical publications
in international journals, books, bulletins, and conference proceedings.
His papers in Economic Geology and other publications
of the SEG are reproduced on the CD-ROM included
with this volume. He has also written more than 800 unpublished
technical reports while consulting for over 200 mining
companies, seven governments, and four international agencies
in 97 countries around the world.
When not working in the field or writing up his observations,
Dick has committed his time to education in economic
geology. He has been an invited speaker at 95 international
conferences to date, co-convened five major conferences,
presented 40 public lectures at universities, geological surveys,
and scientific meetings, given 16 short courses at universities,
geological societies, and conferences, delivered 45
in-house courses for mining companies, run 17 field courses
for mining companies and other organizations, acted as Associate
Editor, Revista GeolĂłgica de Chile (1986âpresent),
Member of the Editorial Board, Journal of Geochemical Exploration
(1994â1999), and Honorary Editor, Resource Geology
(2007âpresent); and was SEG President (1999â2000),
the IAGOD Regional Councillor for Europe (1980â1984),
and the UK correspondent for IGCP Project 342, âAge and
Isotopes of South American Oresâ (1993â1997).
This prodigious body of work has made it virtually impossible
for a geologist to work on a copper deposit today without
benefiting from Dickâs field observations and genetic models.
His ferocious work rate has led him to see more orebodies
and prospects and to meet more economic geologists than
possibly any other geologist to date.
A highly commendable aspect of Dickâs work is the large
number of people who have shared in his studies and publications.
Dick is consistently generous in the recognition of
other peopleâs ideas and meticulous in referencing previous
work.
Another commendable aspect is his clarity of writing and
oral presentation. He goes quickly to the issues of most importance
to his audience and delivers conclusions and opinions
that are valued. He is also never afraid to admit uncertainty
when these circumstances arise.
It seemed an almost impossible task to summarize Dickâs
most significant accomplishments but an attempt has been
made in the Table below. Reading through this list gives some
appreciation of his contributions. However, to many of us who
know Dick well, it will fall short in really describing the man.
He is never condescending or self important, is always good
natured and humorous, and always treats people with the
same courtesy and respect regardless of their age or position.
Finally, while Dickâs name does not appear on the editorial
list, I can confirm that his skill as an author and his commitment
to this project have resulted in an outstanding publication.
The eagerness of the most knowledgeable copper geologists
to volunteer papers for the volume reflects enormous
respect and admiration.
It is a great pleasure for Rio Tinto Exploration to help with
the production of this volume. It will stand as a cornerstone
reference on copper deposits and as a fitting appreciation to
Dick for his outstanding contributions.

Or more to the point, here is his presentation on Porphyry and Epithermal Deposits and it covers basically the geology that created the Alto. Note that in slide #2 he shows the gigantic Grasberg deposit as an exampleâŠvery nice! 
What he will bring to the table is tremendous perspective on just where the Alto fits in compared to the hundreds of other gold/copper deposits that he is familiar with and that he has created ore body models for.

You donât do something like this without, triggering some peoples antennaâs in the mining community. The majors are depleting their profitable reserves, they need new profitable reserves. This will draw their attention to wonder what the potential is here. You donât bring someone of his caliber and statue , unless your fairly comfortable that you have the goods.

And donât forget âDr. Jannas is an experienced exploration and mining geology professional that with a successful international track record in identification, acquisition and discovery of major deposits. Raymond has a Ph.D. from Harvard University and more than 30 yearsâ experience in mining geology, exploration, business development and strategic planning with companies such as Minera Fuego, Hochschild Mining, Gold Fields, Metallica Resources, LAC Minerals, Bond Gold, and St. Joe. Dr. Jannasâ main focus has been in exploration and business development in Latin America (principally Argentina, Chile, Mexico, Peru and Venezuela) in addition to world-wide project generation.â
http://cexr.cl/congreso/en/advisory-committee/
Did Dr. Raymond Jannas recommend bringing in Dr. Silltoe because he was just a little impressed at what he was seeing on the ALTO, or does the ADL appear to be a WCD? Apparently Maurizio Cordova and Dr. Jannas are thinking WCD. Just how will having Dr. Silltoe produce an evaluation report of the Altos de Lipangue Mining District contribute to an understanding of the economic value of the ADL?

Just for that Rick Iâm going to bore you with yet another diatribe and if you continue to hound me Iâm going to buy you season tickets to the upcoming OSU Beaver football season. If Sillitoeâs report is kept solely for âinternal purposesâ Iâll take a stab at how the abstract will read. My guess:
"The noteworthy characteristics of the ADL twin porphyry system are four-fold. First of all the vertical depth of emplacement of especially the easternmost Cu-Mo porphyry appears to be very favorable because of the grades of moly detected in the soil sampling at the Pegaso Nero. Those grades found at surface are reminiscent of the mega-moly mines found at Climax, Henderson and Cuesta. The presence of potassic alteration in the form of potassium feldspar is also indicative of close proximity to the porphyry stock (Lowell-Guilbert model). [NOTE: Dick Sillitoe did a 1974 paper on the vertical depth of emplacement of the average copper porphyry. He found that the average depth for the TOP of the average porphyry deposit is in between 1.5 and 3 Km. The average depth for the moly layer (found near the base of the porphyry) might be 3 Km to 4 Km or so i.e. not at surface like at the ADL.]
Secondly, the low to intermediate sulphidation state epithermal veins found in the Merlin/Fortuna area are noteworthy not just for their high grades but also for the fact that the four typical levels to these systems are all still intact including the carbonate level. The âbonanzaâ grade gold, as is the norm, is found in an area with the silicates presenting with a chalcedonic texture (milky quartz) which is indicative of a âboiling zoneâ. With depth the silicates transition into a more coarse quartz texture near the area where the high grade gold would be expected to transition into a base metal zone. Closer to surface the veins take on a crustiform texture and the typical âbandingâ pattern is found suggesting many phases to the mineralizing events.
Thirdly, the overall twin porphyry âsystemâ presents in a very classic fashion with all of the standard adnexa to these systems present. These include stratabound copper/manto presentations, skarnified areas/replacement deposits, an intact epithermal system, porphyritic textures, etc. Fourthly, the preliminary size implications are very large. The hyperspectral satellite imaging study performed by C.S. Perez revealed a 7 Km swath of about a dozen intrusives extending in a northeasterly direction across the southern downslope off of the centrally located plateau. This suggests the potential for a very significantly sized polymetallic deposit.
The Re/Os studies carried out by Aguilera in conjunction with a Canadian lab reveal the same approximately 91 million year old age of the very large Andacollo Mine to the north of the ADL. The suggestion is that the Chilean Coastal Cordilleraâs âEarly Cretaceous Porphyry Beltâ does indeed extend south of the Colliguay and Llahuin deposits and includes the ADL mining district. This should provide plenty of data to make comparable analyses between the various deposits contained within the belt."
NOTE: This is not the work of Dr. Sillitoe but instead a very rough guess as to the highlights of his upcoming report which we may or may not have access to.
HeyâŠhe has done a lot more since 2011âŠyou cut off all his most recent work!
His journal article âPorphyry Copper Systemsâ that came out in 2010 is so popular that it listed as #4 most read article as of February 2017 in the Economic Geology Journal. I managed to get a PDF copy of the article and it is good stuff.
Why some are dumping is beyond me, we probably have something big here,you should buy not dump,especially at this price.
