Porphyry and Epithermal mineral Deposits

- Welcome to Geology Simply Explained. The purpose of these videos is to provide very simple explanations of very complicated geological processes that form mineral deposits so that you may become more familiar with some of the terms and concepts that geologists use to describe their field. In this one we’re going to discuss Porphyry and Epithermal deposits.
Often corporate news releases and reports can be very complicated with technical terminology that’s foreign to most of us with only those trained in this field being able to understand. There’s a good reason for this, it’s a very complicated field! Another reason for these videos is to draw awareness to the publicly traded mineral exploration companies that we operate. These are some of the geological models that Eagle Plains Resources (TSX-V:EPL) and Taiga Gold Corp. (CSE:TGC) use to guide mineral exploration programs at their projects located in western Canada.
We use labels to group similar types of deposit processes under one name, but because these are natural processes, this is a generality, and never are two of these exactly the same, only that they are formed by a similar set of processes. Occasionally, even after a deposit has been mined, providing maximum understanding of its nature, there can be disagreement as to what type of deposit it was. We hope that this series of videos will provide for some basic understanding of this science that involves an incredible natural system evolving over a period of time that is truly mind boggling.

I have long wondered how atoms of a particular element form in clumps that can range up to pure veins. I thought it had something to do with water, temperature and pressure but your explanation of the process answers all my questions. Thank you!
Fantastic! As these are extremely basic explanations you may wish to delve into how mineral bearing fluids react chemically and physically in certain environments to deposit the minerals they are carrying. I understand that there are many variables and some that have been described to me by our geologists are fascinating, in particular where sulpher is involved.
Great! The explanation is quite simple to understand
thank you for great sharing and helping us more understanding in basic
Very good video, it clears up a lot questions.
Thank you,much love from Zimbabwe 🇿🇼 @
Thank you sir!
Hi Mike,
Thanks for taking the time to share your knowledge in a simplified and concise presentation.
Hi Mark,
Thanks for your comment! I'm happy you found this interesting.
Great explanation
Like it. Nice one.
Great explanation!
dude, your voice is way attractive more than porphyry system itself.
Hi Steve, I wish it were my voice, more explanations to come when I find the time and these will be in my voice which, unfortunately, isn't near as nice as the current narrator.
Wonderful explanation of porphyry Copper
Very interesting and informative, thank you.
You are most welcome, glad you enjoyed.
useful information, thanks
Thanks. Your videos help us to learn and enjoy about Geology.
You are very welcome, I'm happy you found this is enjoyable and infomative, objective achieved!
Nice. Wow!
Thanks for the explanation!
You are very welcome, your comment of apprecition is great feedback and compels me to create more.
Thank you sir.... Nice explanation...
You are most welcome, thank you!
Thanks for Sharing
You are most welcome Mateus!
Is that what's under our feet, thanks for the heads up!
Good
Thanks for this! A question then: Due to the relationship between epithermal deposits and porphyries - could one not say that whenever you find an epithermal deposit, there will be a porphyry below? So, then you found two with one strike?
In a perfect scenario you're correct but there are other factors that come into play. Weathering is one, faulting is another which may disperse portions of any deposit type. Epithermal deposition can occur at considerable distances from the porphyry itself, so where is the porphyry relative to an epithermal expression? Another consideration is that the epithermal portion, if intact, may be considerably higher in the stratigraphy than the porphyry portion in which case the porphyry may be buried too deep to extract economically. This is assuming that the porphyry is actually mineralized. These are to mention just a few of the pieces of the puzzle that geologists have to consider before deploying loads of money to test their hypothesis.
I be a lookin' fer this....
In which context do you use hydrothermal fluid?
Do you include magma as a hydrothernal fluid?
In a way it is yeah.. but mostly an hydrothermal fluid is the magma that contains any kind of liquid that comes from the minerals like H20, CO2 etc , or the water from the sea or the rain! To put it in a more simple term , the magma at it's beginning of "life" isn't hydrothermal fluid but when the water enters the magma it becomes h.f.
Hi. Sir.
I need your help. I have large area to detect by remote sensing
I'm sorry but I can't help you with that, good luck with your project!
I am a Geologist
Why are you watching this video? I’m in a process of starting a gold exploration project for my mining company the first of many projects to come.🙏🏿⛏️
Im taking a course on resources this sem
The geologic time line that this video claims for the majority of gold deposits is 100% wrong!!
Hi Johnny, these explanations are for relaying the very very basics of how the mineral deposit types that Eagle Plains Resources explores for are formed. Perhaps you can help us all learn more by providing your understanding of the geologic timeframe in this instance. To use your words, "100% wrong" is quite a large span of time, can you clarify this?
