"The Muketei Metallotect in the Ring of Fire - An Emerging Base-metal Camp"

Thursday, MARCH 23, 2017
at 5:00 pm in CB 3031

Abstract: 
The “Ring of Fire” (ROF), also known as the McFaulds Lake greenstone belt, is an arcuate Archean greenstone belt >200km long located largely under the cover of the James Bay Lowlands in Northern Ontario. Since the initial mineral discovery in 2002, exploration companies have discovered nine deposits of magmatic Ni-Cu-PGE, chromite, and VMS Cu-Zn with estimated resources and/or reserves, and over 50 polymetallic occurrences. Work by the OGS and GSC over the past six years has led to the identification of seven distinct assemblages within the ROF (Metsaranta et al., 2015), of which the Muketei assemblage is by far the most well-endowed as it hosts all known chromite and Ni-Cu-PGE deposits, and a large proportion of the known VMS occurrences.
The Muketei assemblage is a magmatic-volcanic succession interpreted to have been deposited during extensional rifting of older evolved crust, ca. 2735 Ma. Tabular sill-like ultramafic bodies emplaced at or near the contact between basement tonalite and an older supracrustal sequence are interpreted reflect komatiitic magmatism derived from high degree partial melting of the mantle. Feeder systems to these ultramafic sills are locally well defined and have the potential to host significant high-grade Ni-Cu-PGE mineralization as at the Eagle's Nest deposit. World class chromite resources occur stratigraphically above Ni-Cu-PGE mineralization as thick accumulations of semi-continuous strata within two main sill complexes. A regionally extensive sequence of ferrogabbro sills and lesser large layered intrusions occur higher up in the stratigraphy and are known to host Ti-V-Fe-P mineralization in cumulate horizons. The relationship between the ultramafic sills and regionally extensive ferrogabbro sills remains unknown, but we speculate the two are genetically related, either as co-products of high-degree partial melting in the upper mantle, or as end-member fractional crystallization products of mantle melts at higher levels in the crust. The latter has the potential to impact exploration targeting within the Muketei assemblage as the presence of thick ferrogabbro intrusions may provide a vector towards smaller ultramafic intrusions with potential for Ni-Cu-PGE and chromite mineralization.
The Muketei volcanic sequence, located generally above the ferrogabbro sills, is a folded, bi-modal volcanic succession up to ~10km in mapped thickness and hosts the McFaulds #1 and #3 Cu-Zn VMS deposits in the south, and the 5.01 Zn-Cu VMS occurrence in the north. Age determinations for the volcanic sequence (Metsaranta et al., 2015) indicate that it is contemporaneous with ultramafic and mafic magmatism at depth, suggesting the heat source which generated the felsic volcanic melts, and possibly the hydrothermal systems, may be linked to their emplacement.
The Muketei assemblage is unique in the ROF with its extraordinary mineral endowment and the contemporaneous nature of its magmatic and hydrothermal mineral deposits. In this respect we recognize it as a mineral Metallotect of which we are only just beginning to understand and appreciate its characteristics and spatial extent. Questions remain as to why the Muketei is so unique relative to its sister assemblages in the ROF and to other greenstone belts in the Superior Province and beyond.

About the Presenter: 
Ryan Weston, Noront Resources’ Vice-President Exploration, is a Professional Geologist with over 15 years’ exploration experience nationally and abroad. He has explored for VMS deposits in the Mexican Cretaceous belt, komatiite-hosted Nickel sulfides in Australia’s outback and porphyry and epithermal mineralization in the Peruvian Andes.
Since 2012 Ryan has been focussed on exploration and development within Ontario’s highly prospective Ring of Fire district which hosts world class chromite resources, a significant magmatic Ni-Cu-PGE deposit (Eagle’s Nest) and numerous VMS occurrences, all discovered within span of less than 10 years. Ryan is an ardent believer in the continued prospectivity of the belt and believes there are more high-quality deposits yet to be found. Ryan received his MSc in geology from Laurentian University in 2002 and is a recent MBA graduate from the Smith School of Business at Queen’s University.

"Data Interpretation and Integration from a Seismic Perspective - The Excitement of Innovation"

Abstract

It’s a little cliché to say, but technology is changing so fast that it’s difficult to keep up. Computer storage, processing speeds and visualization capabilities continue to grow exponentially; “integration” (however difficult it is to define) is the dream of most geoscience departments and generic “big data” analysis techniques are evolving rapidly – this is indeed an exciting time to be a geophysicist, a scientist, a human being.

Geoscientists are the Google Translate of the oil industry; our job is to translate the coded information in the data we gather to English (or other language of choice). We used to do this with creatively hand drawn and coloured maps and a generous amount of intuition – now we use sophisticated algorithms and powerful visualization, although intuition and creativity are still most definitely required. With all of these new tools, what is the current state of our effectiveness as translators? What are some of the exciting developments? What is the future vision and how do we get there?

Most companies and research groups are working to some degree to incorporate multiple data types (such as seismic data, well logs, production information, microseismic, etc.) in their interpretations of and predictions from the data they acquire; the more pieces of the puzzle added, the clearer the picture. Integration methods range from simple visual comparisons of maps made from two different data sources to numerical modelling and statistical procedures at a basic data level. Quantitative Interpretation (QI) is a broad approach that encompasses many linked techniques in its aim to extract geological properties from seismic data. These geological properties can then be included in analytical methods to determine the key factors in predicting the future performance of a hypothetical well or field.

QI involves a series of analysis steps that each require input datasets, mathematical functions and parameter selections. Choices are made at each point that affect the outcome to some extent, so the more experienced the practitioner; the more times they have seen a particular situation and learned from the results, the better the choices and the higher the chance of a satisfactory outcome. By satisfactory, I mean a realistic prediction of geology from seismic data that not only matches the existing wells, but also predicts the geological conditions in an undrilled location that turn out to be correct. This is an accepted and effective process that has been adopted around the world to reduce exploration and development risk.

Much of the credit for the degree of success of the QI outcome can be attributed to factors that are beyond our control, such as the inherent elastic contrasts and intrinsic properties of the rock, the conditions in the near surface (on land or water), the weather on the day the seismic data were acquired. However if we go beyond face value, regardless of quality, the seismic data always contain more information than we think. QI encompasses the best methods currently available to dig deeper and reveal the hidden information. So, how do we make it better?

Aside from improvements in the theory, which is ongoing, we make QI better by increasing the quality of the inputs, ensuring the appropriateness of the assumptions underlying the mathematical functions, testing the correctness of the parameter choices, and doing everything faster than ever. This plan sounds straightforward, but it’s almost never obvious how to make these workflow improvements. This kind of challenge is where big data analytical techniques with a corresponding increase in computer processing speeds and capability (eventually even quantum computing) can be introduced. Seismic data has always been big, but seismic analysis is mostly linear: the output from one process is the input to the next. Analytical techniques allow lateral analysis that geoscientists are only just starting to touch on. Statistics and machine learning are much more mathematical than most of us are comfortable with and the approach doesn’t necessarily come easily for geoscientists who are used to seeing a direct cause and effect to their analysis. However, as long as we maintain a good balance of objective mathematical process and subjective geological sense, this new direction should reveal new insights and enhanced efficiencies and, perhaps most importantly, be a catalyst for integration.

But how do we get there? It’s hard to argue with the potential benefits of a more complete and thorough analysis of the range of available data, but there is plenty of debate about appropriate and effective procedures, near term objectives, and in a business environment, the best use of limited money. Shortcuts are tempting. Instead of saving money, however, shortcuts usually expose large gaps or inaccuracies in our knowledge – which is not always a bad thing.  Collaboration, integration, models of all kinds (scientific and business) and a little bit of faith are therefore necessary to understand, effectively communicate and eventually achieve the ultimate benefits of a significant paradigm shift.

My presentation will not necessarily answer all the questions posed in the abstract, but there will be explanations, examples and opinions.

Biography

Laurie Weston Bellman’s career as a geophysicist in the oil and gas business has spanned almost 30 years so far.  During that time, she has seen the science (and the business) from many different perspectives.  She has been part of the evolution of exploration objectives and analysis techniques, both as an interested observer and an active contributor.  Originally a Physics/Astronomy graduate from the University of Victoria in B.C., Laurie has enjoyed a variety of career challenges in Canada and internationally.

Laurie started her career with Shell Canada in Calgary doing seismic processing and interpretation in the central plains area of Alberta.  Looking for adventure and travel, she took a position with LASMO plc in London, to work on various European, North African and Middle East projects.  Upon her return to Canada, Laurie began a consulting contract with Nexen Canada Inc. where her main professional interest migrated to the Canadian oil sands.  Based on that interest, she founded her own seismic consulting company in 2007 called Oil Sands Imaging, which was later re-branded as Sound QI and sold to Canadian Discovery in 2012.

Drawing on her experience as a seismic interpreter in many basins around the world, Laurie is well aware of the combination of hard data, imagination, creativity and collaboration that is necessary to be an effective and successful member of an exploration or development team, regardless of background.  At the same time, Laurie's education in physics and astronomy, and her early career as a seismic processor have given her a respect (and healthy scepticism) of data and data analysis.  The integration of all these aspects is her objective in her current role.
