Development of a representative hydrogeologic conceptual site model (CSM) is an iterative process that begins during mine exploration and permitting and continues during operations and mine closure and reclamation. Hydrogeologic data sources, field data collection methods, and analysis methods will be reviewed to efficiently characterize groundwater flow systems including effects related to mine dewatering, infiltration, and water management. Accurate characterization of geologic structures, preferential flow pathways or barriers to flow, recharge and discharge areas, and groundwater interaction with mined materials (ore, waste rock, and overburden) can streamline mine operations and may allow alternative closure and reclamation scenarios.

Hi NorCal SME Section, Please join us for an online meeting on Wednesday, January 28 at 4:30pm. Agenda: Kick off  (Ed) Treasurer report (Tyler) Mineral-X (Chris) Guest Speaker (Alan Levy) The Mountain Pass Rare Earths Mine Story Alan Levy is an exploration geologist and minerals economist.  His work history includes stints as Manager Business Development and Senior Minerals Geologist for Molycorp in Denver, Los Angeles, Sri Lanka and Anchorage.  With a specialization in rare earths, exotic and high-tech minerals, he is responsible for discovery of a heavy rare earth/zirconium deposit in New Mexico, which led to a world-wide search for similar deposits.  He has had a separate career in the fertilizer industry (Unocal Chemicals and Agrium), as Manager of Logistics/Distribution/Transportation as well as Industrial Chemical Sales and Marketing.  He earned his bachelor’s and master’s Degrees from Queens College, N.Y.   Alan will describe the geology, mining and processing of the Mountain Pass rare earth deposit in SE California and its history of ownership and operation to the present day.  He will strive to position this in the context of the world's rare earth deposits and developments in this new age of critical minerals, government guarantees and independence from Chinese sources.

Consider using a headset, to prevent feedback from your computers speakers. Try using the "Chat" to text/message people during the meeting. "Raise hand" to get the attention of the facilitator or speaker if you wish to interject.   Use the camera if you are comfortable and internet allows it.  It is nice to see the faces of new members and build familiarity. If the meeting feed is choppy/slow, try turning off your camera to reduce data.

Creation of a new sustainable energy infrastructure, carbon sequestration, advanced electronic and computer technologies, and advanced defense technologies all mean that the demand for metals is increasingly rapidly. But traditional mining technology can be highly environmentally damaging. This means that the supply chains for many critical metals and semiconductors stretch through unstable parts of the world, leaving them vulnerable to disruption and exploitation. Biomining with Acidithiobacillus species already supplies about 20% of the world’s copper and 5% of its gold through an iron-specific redox process. However, there are no industrially-used microbes for any of the 30 or 40 other critical elements. This means that we will need to build microbes to enable bioprocesses to mine these elements with synthetic biology. However, we do not understand the basic science of how microbes interact with metals and minerals sufficiently to guide this engineering. My lab has characterized the genome of the mineral-dissolving microbe Gluconobacter oxydans and discovered the genetic systems that enable it to mine rare earth elements. We have used this new knowledge to create a roadmap for engineering G. oxydans that has already improved biomining of REE by up to 1,200%. Furthermore, we engineered the hyper-engineerable microbe Vibrio natriegens to separate adjacent heavy lanthanides, leap-frogging solvent extractions. However, this still leaves over 20 other critical elements that we need build microbes for. To build the basic knowledge for this, my lab has started the Microbe-Mineral Atlas to catalog metal and mineral-interacting microbes from around the US, and hopefully the world. Finally, I will discuss some of the barriers that our current model of technology transfer poses to development of new technologies, what we have done to solve this problem, and some recent successes in starting REEgen for biomining rare earth elements, and Forage Evolution to develop hyper-engineerable microbes.
