Country Rock Contact

Winter 2009 I feel sorry for not following up sooner. This is suppose to be winter 2011-2012, in reality we had very little winter so I have been working at the mine through what should be winter. This leaves little time for writing. I will try and catch up shortly but mining is my passion and writing does not come close.

Although mining alone is great therapy it is nice to see fellow rock enthusiast occasionally, although it does have a tendency to slow down production. Terry Szenics whom I purchased the Havey mine from and Ray Woodman stopped by for a visit. Both are very knowledgable about Maine mining and have some very interesting stories to share about their past mining and mineral adventures. With Terry living in the New York area and owning a mine in Maine, it made it hard to work so he decided to sell and I ended up being the lucky individual who bought the Havey. Terry mined the Havey back around 1976 blasting and removing about 1800 yds of material. Removing this rock sure made my job a lot easier when it came time to start moving rock. He had made a nice trench for me to be able to work off from. Terry has had many mining successes in his lifetime of mining including a significant find of purple apatites at the Pulsifer quarry at Mount Apatite, which is only about a mile as the crow flies away from the Havey. Ray Woodman a retired State of Maine geologist had what many considered one of if not the best collection of Maine minerals which has gone to the Maine Mineral Museum which should open in 2012 in Bethel. Ray had purchased some of the specimens that Terry had found during his mining episode at the Havey including  some cinnamon colored tourmaline. I was envious. I guess I will just have to do some more mining and hopefully there are more cinnamon tourmaline crystals left.

Ray Woodman and Terry Szenics visit the mine. Ray may not be as spry as he used to be but he is still keeps his ear to the ground on what is going on in the Maine mining community. Terry liked the "new drill".

As the temperatures cooled down I gave up on trying to work the mineralized zone and switched over to improving my access. As I was going deeper chasing the core zone it was necessary to lower the access road into the mine so that I could get the machinary in with some relative ease and not have too steep a grade. In reality this meant that I needed to blast the wall back. One good thing was that the ledge was slowly dropping so even though the mineralized zone was sloping down, the grade was sloping down with it but not as steep of an angle. With the grade sloping down it would make getting down to the mineralized zone easier. In doing this work I started to come in contact with the country rock(rock formation that surrounds the pegmatite), in this case it is mostly gneiss. Many places in this area the glaciers have removed most of the country rock and left the harder pegmatite in place. As the top of the ledge slowly drops I am running into the country rock on top of the pegmatite. This can be somewhat problematic with blasting, in certain areas of the contact, the country rock has decomposed and there is a void between the top rock types. Much of the energy of the blast if allowed to will escape into this void and little rock will be moved.

A warm spell in December means the ability to get in another day of mining in the mineralized area. You need to be quick and with the daylight ending early it means you might need to work under lights. If you wait too long, things may be snowed over and this makes it very difficult. Ray Sprague and I opened this pocket up late one afternoon only to come back the next day to not only cold but a light coating of snow. As it was getting late in the year it was time to give up and start thinking about spring.

Tourmaline Crystals

Fall 2009 After the quartz pocket more blasting was done. A large feldspar crystal showed up, with one area being very orange with dendrites. I very good sign. The feldspar was very fractured and I was able pull the feldspar apart with the hammer and chisel. I quickly broke into a pocket that was full of kaolin. Kaolin is a soft white clay found inside many pockets and very easy to dig through. Inside the kaolin I could feel a quartz crystal. As I dug through the kaolin the crystal kept increasing in size until it was roughly 20cm in diameter. Where this crystal was totally enclosed in kaolin I got excited thinking it would be beautiful and flawless. Although encased in the kaolin it was slow work digging it out It probably took 30 minutes to dig all around it so that it was free to be removed from its home for the last 300 million years. Upon being removed from the pocket and washed off, although it had little damage, it was not the beautiful smoky that I was hoping for. Going back into the pocket some additional quartz crystals came out and then as I dug deeper into the kaolin I pulled out my first tourmaline crystal. It had been a long time coming but at this moment it was well worth it. It was the typical Havey greenish blue. Tourmaline is dichroic meaning looking through the crystal sideways it is one color and looking through the end it is another color. This can make it a challenge to cut for gemstones as there will be a mixture of the two colors in the cut stone. The Havey tourmaline is blessed with having great color in both directions in the a,b axis it is a greenish blue(teal) and looking down the c axis or end it is a mint green with no olive color to dull it down. This gives a very unique and desirable color to the cut stones and many of the cut stones will be eye clean.

I was able to keep removing the feldspar  away from the pocket so as to have good access. Of course at this point I did not have my camera so no  pictures of this pocket were taken. I have found that cameras and mining are a tough fit with all the rock, grit, water, and delicate moving parts on the camera. I seem to go through a fair amount of them. This turned out to be a small pocket with only a few terminated crystals and only a small amount of gem rough. In the bottom where a few matrix specimens with the tourmaline in cookeite. Hopefully this was just a taste of things to come.

Finding the tourmaline is definitely one of the reasons that I was mining. It is very exciting to pull these rare crystals out of the ground and be the first person to see them. When Havey was mining in 1910 he hit several pockets that summer and fall. Many spectacular crystals came out of those pockets, the largest measuring 3.5cm x 15cm. The larger tourmaline crystals have a tendency to have many fractures and inclusions with many of the smaller being very clean. I had visions of finding more and figuring with the modern mining that I was doing, versus what Havey had in 1910  it should be relatively easy for me to find. How wrong this thought would turn out to be. I continued to move rock late into the end of the year with no more gem tourmaline to be found.

Fall Mining

Fall 2009 Mining in the fall is great. There are no bugs, the temperature and humidity are very comfortable and ground conditions are still fairly dry so it is easy to keep ahead of the water. The down side is winter is coming but there isn't much we can do about that. After exploring more around the small tourmaline area without much results it was time to move on which meant more blasting. I still had quite a bit of mineralized area to work through so I had high hopes of finding more tourmaline. Of course where I was blasting through the mineralized zone it meant that the blast would need to be small so as to hopefully not damage anything interesting. After I couple of blast I found an area that turned out to be what I refer to as classic Havey quartz pocket. As you start to approach the pocket the quartz and or feldspar is very fractured. On the outside edge of the pocket you can remove the feldspar and quartz with your bare hands. As you work further into the pocket there is a layer of cleavelandite. Inside the layer of cleavelandite you will start to find the quartz crystals. If you are at the top of  the pocket they are typically smoky. Toward the bottom they become a light citrine to clear. At the Havey many of these pockets have a false bottom and if you break through the massive quartz layer in the bottom you are apt to find some additional pocket material. In this pocket as I broke through the bottom there were a few apatite crystals hiding out.

Although this pocket was the largest that I had found up to this point most of the specimens were mediocre. The smokies were light and mostly broken. There were some micro quartz crystals in a few areas. There were a few good light citrine quartz crystals that I will get some pictures of at a later point. The pocket was about .75meters wide x .75meters long x 1.25 meters deep. Even though the quality of the crystals was not great it was still interesting to see what the pocket held.

Highly mineralized area

First Gem Tourmaline

Summer 2009  It is a little frustrating to be mining for tourmaline and not have anything to show if someone should ask. At this point I had found a fair amount of tourmaline specimens frozen in quartz and there was much of it in the muscovite books but I didn't have any crystals that had come from a pocket. There has been much written about the tourmaline from the Havey how it has a beautiful unique bluish green color, and how clear it is. I wanted to find some and the other treasures that might be hidden with it. There were also stories about how the Havey was all played out. This had concerned me some when I had originally thought of buying it, but there had been some recent finds in the Berry and some of those were pretty close to the Havey quarry. The Berry and Havey quarry are the same pegmatite and the mineralized zone that I am working has been worked extensively on the Berry side. The only thing separating the two quarries is the property line.  I thought it was worth a try mining the Havey and with the mineralization that was being exposed I felt pretty confident that something would show up. It was just going to be a matter of moving more rock. The more I read and started to understand what was going on, the more confident I felt. Every blast was revealing more of the core zone and its complexities, and, of course, there was more tourmaline showing up...but I was hoping for better quality.

As I started to clean out from the last blast I could see some small pieces of green. I was very quick to hop out of the excavator and see what was down there. It turned out to be some small pieces of gemmy tourmaline. The excavator was shut off and the hand work started. It was a little frustrating to know that the one spot that I chose to blast through the mineralized area would end up being the area that had a tourmaline pocket. As I slowly worked my way through the rubble, an area of kaolin started to show up. As I washed this area down, fractured tourmaline crystals frozen in the matrix started to show up. The kaolin turned out to be void of any crystals and overall, even though it was the first pocket to have some gem tourmaline, the pocket did not produce much but some small shards and small specimen pieces most of these in a lepidolite like matrix. Expanding on this area didn't reveal much else in the way of any pockets or tourmaline although it still looks interesting. Some of this area is as close as I want to work toward the Berry Quarry as I am lower than the pond on the other side of the property line and I would like the water to stay on that side.

Working my way blasting through the mineralized zone the next interesting area was some morganite crystals showing up in the massive areas of lepidolite. Some of the crystals were pink on one end and a light blue on the other. The Havey quarry is not well known for gem beryl but with all that is showing up I would assume at some point in time that some will be found. Behind the lepidolite masses there was some quartz and in one area there was some voids. These were not the typical pocket structure but there was some spaces and they were filled with some beautiful smoky quartz. Much of this came out in pieces but there were several nice specimens that came out.

Mineralized Bench

Manchurian Warrior

Spring 2009 With winter hanging on and anxious to get some blasting done the excavator was brought up to move some of the snow aside. Where I am not mining up in the mountains like many of the miners I can get an earlier start than most of them. Many of the mines in Maine are up in the foothills and mountains of Oxford county and can have many more feet of snow than what the Havey gets, plus some of the mines have long tough access roads which can be difficult to traverse in the summer so it is very tough for them to get much of an early jump on spring. It was mid march and the days were starting to warm up, so after the snow was moved from the area to be worked what little remained melted quickly. The first blast of the new season went off and the Havey was up and running. I felt very positive that we would be finding some interesting minerals in the near future. I had some great looking areas to work and many words of encouragement of how promising things looked. It took several more blast to get to the depth that I needed and to edge of the quartz pod area. As the quartz pod was reached and shook up I brought out the hammer drill and did some serious hammering. There was an albite cleavelandite rind around this area which was relatively soft so hammering out material was fairly easy although in reality I didn't move much rock. On the edge of the quartz I continued to find some tourmaline fans and some of these came out in some fairly good size pieces. Most of this tourmaline is fairly light colored and has altered more to a clay than tourmaline. As I exhausted the area that I could work with the hammer I put in another blast.

This blast opened up the mineralized zone with several large areas of lepidolite and several large areas of quartz.There was also some large blocky feldspar. Several phosphate pods showed up. These are good areas to look for rare and or even unknown minerals, although the ones that were showing up here had mostly been altered. Many of these as far as I am concerned are grouped in the uglier than sin category but to each his own. This area was almost 20' long and looked extremely promising. This was all happening as the same to that the Maine Pegmatite Workshop was taking place and the group stopped by for a visit to explore the pegmatite. As the mineralized zone was running into the bottom of the quarry it was the general consensus from several of the experts that the hole needed to be deeper. That seems to be a common theme in that all you need to do is go deeper and there it will be. It is not quite as easy as it sounds. Some of these pegmatites don't like to give up there depths to blasting very easily.

After the peg workshop left it was time to move forward. With all the mineralization showing and it looking promising, a decision was made to try and do a cut through the mineralized zone and then loosen it with a blast from the back side. I knew I would need to go deeper at some point but I was a little anxious to see what may be hidden behind all the mineralization. It was difficult to choose a spot as it all looked promising for potential pockets. The spot was chosen and blasting through the zone started. Several small blast were done in trying to reach the backside of the mineralized zone. 

Blasting finally starts

Late fall 2008 . Around the same time as I was working the large mass of quartz and finding the pockets the old air track drill showed up. This machine is an antique but the price was right and for the amount of drilling I would be doing it would work fine. The drill hadn't been used in over 10 years so it was in need of some tlc. A few hoses needed to be replaced and I took the hammer apart and cleaned it up. I did some general service work on the compressor and then it was up and running. Many of the miners in Maine are drilling with a hand drill and compressor. This is hard work and some what slow, where I was a one man show and had a fair amount of rock to move using the air track seemed like the correct route to go. I found out that as long as you had good going and a relatively level area to work the air track worked well but there are times due to some steep slopes or access is that it is much more challenging. I need to make a road every where that it needs to go and there is constant moving of the air hose(bull hose). They don't call it the bull hose for nothing as it needs to get bulled around and it is not very light or manageable.

drilling to help create better access

The frustrating part of doing the first several blast is that it would not benefit me in any way of finding any new mineralized areas. I was doing the blasting to get better access into the mine. This had been a concern from day one and I had devised a plan to start to lower the south east wall to make it easier to get man and machinery in. This was going to be a fair amount of work with no immediate gratification but it would make it much easier to work for the long haul. Also the mineralization was bumping up against this area and some of this rock was going to need be removed in the near future if I wanted to continue and explore the mineralized area.

I was having a difficult time trying to decide where to start blasting for the mineralized area and not do any damage to any of the potential pockets. I new where I wanted to get to and that would be the quartz pod with all of the tourmaline in the matrix. The areas surrounded it also looked somewhat promising with beryl, large blocky feldspar, schorl to name a few. When I was cleaning up from the blast for lowering the entryway I found a fracture in the ledge and was able to rip up a slab that was probably 15 ton. In doing this it was easy to see that underneath the area of schorl the rock turned to junk. This made it very easy to choose where to start to go down. I would be able to start blasting just se of the basalt dike. The basalt dike typically will stay in place if you blast on one side of it and give a clean wall. This also would keep me far enough away from the quartz pod area so that I would not damage it. Before winter set in drilling was done so that in the spring blasting could start in earnest and hopefully find the tourmaline pocket.

Putting the Havey to rest for the winter 2008

Tourmaline Frozen in the Quartz

Fall 2008 After locating the lepidolite on one side of my access road and the quartz pocket on the other side it was time to see what was under the road. This would mean that I would lose my easy access for awhile. As I started to clean  the material off the ledge a large area of schorl showed up. Schorl is very common in the quarry but not in the volume that it was showing up now.

Plenty of schorl it mixes with green tourmaline closer to the pump. The green tourmaline is poor quality and very crumbly. You can see a split in the basalt dike right behind the pump.

 After the schorl area as I was raking the excavator teeth across the bottom of the remaining pile Rod Stone showed up to see what was going on and hollered for me to stop digging. He jumped down in the hole and pulled out a couple pieces of opaque watermelon tourmaline. Shutting off the excavator and going to work with a shovel and the hose we started to clean off the area. A pod of quartz started to show up with opaque tourmaline crystals frozen in the quartz. This was very exciting. I had seen seeing hints of tourmaline occasionally but most of it was in muscovite in some of the loose boulders but this was what it is all about. Even though it opaque there was green, pink and watermelon. Also on the edge of the quartz pod was a large area of purple lepidolite. There was a lot of different colors concentrated in this one small area.

Tourmaline mass frozen in quartz

I cut out the tourmaline mass above and was rewarded with this tourmaline fan on the back side. Photo area represents 25cm x 25cm.

After carefully cleaning off the area It was time again to get the hammer drill out and start chipping away at the quartz to see what might be hidden from view. I was expecting with each blow that it would break through into a pocket. This quartz was fairly solid and didn't have too many fracture lines in it. As I continued to break away the quartz I found an area with cookeite and got more excited. My experience with the quartz pocket had shown that the cookeite would lead me to the pocket. Following the cookeite led to a small opening that was filled with kaolin and many small smoky quartz crystals. I was hoping that the pocket would open up and there would be  some tourmaline in the bottom but alas this didn't happen.

An overview of the quartz pod. You can see the tourmaline fan that was below the tourmaline mass in the above picture.

Above is the small smoky quartz pocket that I mentioned earlier and then above that was a montebrasite crystal that I was trying to get out in one piece. Luckily for me as I continued to work on removing the quartz around it, the crystal broke into several pieces and there was a surprise inside. If you expand the above picture you will be able to see some small tourmaline crystals in the frozen in the quartz. I continued to work this area off and on to the end of the season without finding much more. I was going to need to blast to make any real headway in finding what was hidden below.

First Quartz Pocket

Late summer 2008. After finding the lepidolite area I would have liked to continue to clean the ledge off but this was my only access in to the mine. As mentioned previously the old access through the Berry mine was no longer an option. Getting into the mine a different way from the access I was using would be very difficult. Since I had exhausted the possibility of finding a pocket in the lepidolite area without blasting and since some of the participants from The Pegmatite Workshop mentioned the prospects on the further side of the mine I decided to do some work on cleaning the ledge off on the nw side. Since most of the trees had been cut earlier this year much of the work involved removing the material that had been dumped there decades before. The material was hauled out of the mine and this area was washed down. It showed some promise with several areas of quartz. When things were wet in this area you could see a glazing of lepidolite on the feldspar. There were several small areas of lepidolite and another are that looked like the bottom of a pocket. I decided after seeing what the prospects were on this side of the mine and the difficulty in working this side that I would abandon it for now and go back and work where I had been originally.

quartz area from the northwest side of the quarry

Back to narrowing up my access road. This time I chose the opposite side and after moving some material a large area of quartz started to show up. This was encouraging at least to me as it was the largest mass of quartz I had seen in the Havey since I had started. It had been mentioned that quartz was an good sign so I took some time and did a closer look. I could see some cookeite and it was time to bring out the hammer drill and start breaking apart the quartz to see if there was any hidden treasures inside. It was breaking apart pretty good and then the hammer broke through into a pocket and things slowed down. I put the big hammer away and then started to approach the area with a little more tenderness. As I slowly enlarged the opening and reached my hand in I could feel the smooth crystal face of the crystal. Pulling out the lose quartz and feldspar that was around it I finally pulled out my first smoky quartz crystal from a pocket. It was very exciting. The remainder of the pocket contained a mixture of quartz shards, feldspar, cookeite, and muscovite pieces. There was also some milky quartz and several more poorly formed smokies. This pocket turned out to be about the size of a volley ball.

When working in these pockets they have a tendency to be packed with different materials. These quartz pockets all had about the same make up as listed above. When working in the pocket it is nice to do it without gloves so that you can feel the crystals although this leads to some pretty nasty cuts. The quartz can have razor sharp edges. Sometimes you won't know you have been cut until you look down and wonder what all the pretty red rock is. In the pockets much of the material is packed in very solidly so it can be quite a bit of work to get out some of it especially in one piece. Many of the pieces in the pockets have fractures or are broken. Sometimes you are able to match up the broken pieces and put them back together. The best a crystal looks is when it is fresh from the pocket. Most of the pocket material that comes out of the Havey is very clean meaning a rinse in the water and you get a good view of what it will look like. Some mines leave a heavy coating of iron or other material on the  crystals.

One of the first quartz pockets. You can see the beginning of a smoky quartz crystal in the hole on the left. Notice the contact with the feldspar and quartz. 

This particular area of quartz I worked off and on over a couple of months. There were several more pockets that had some nice smokies.Almost all of these pockets had one nice smoky at the top(although sometimes it would be heavily damaged and then would have a mixture as listed above. Along with the pockets there were many small vugs that would hold a crystal or two although these were usually smaller crystals. There were many crystal faces along the seems that were discarded because of the poor quality. Some of the smokies had a clear apatite druse covering parts of the crystal faces. Below are a couple of smoky quartz that came out of the first quartz pod.

Turkey Troubles

Spring 2008. The turkeys are coming! The turkeys are coming! There are many farm fields that surround the Havey so it is a common occurence to see turkeys. You can tell that they visit the mine occasionally because of the stray feathers that they leave. Once in a while you will see them on the way in and sometimes, if there are no engines running, you can hear them gobbling. This spring a mother hen decided to make her nest right beside the road to the mine, so every time anyone went in or out she would crouch down so to camouflage herself. If you didn't know right where to look she was hard to find. She did nest far enough away so that while I was working I did not disturb her. Finally, coming in one day most of the eggs were hatched is she and her brood were gone.

The turkeys have left the area.

 Now that the bulk of the excess material was out of the mine I could continue cleaning up the remaining area and see where the best place would be to start mining. Of course I needed access into the mine for the equipment, so this meant that there was a certain amount of area that I would not be able to look at as easily. The pegmatite workshop had asked to come to the mine so I wanted to expose and clean off as much ledge as possible. I am still  new at this and can use some knowledgable eyes to look and give me some direction. As it turned out the most promising areas so far were to be under the road. As I kept narrowing up the road I was able to remove a fair amount of loose rock. The last time the Havey was mined in the mid 1970's Terry Szenics was having a loader come in and remove the loose rock. While using this machine was optimal at the time, it was not able to rip all of the fractured rock that may have still been bound together after the blast. Now, using an excavator equipped with a ripper tooth I was able to tear down through an additional 1' to 3' of loosened  rock. In doing this I was exposing some new ground that hadn't been seen.

Access ramp into the mine. Note the basalt dike on the left hand side of the picture.

All of a sudden some 10 to 20lb blocks of purple lepidolite started to come up. Much of the lepidolite from the Havey is a fine grained purple and takes an excellent polish. It was time to take a closer look. I didn't always have a camera handy and this was one of those times. There was a lot of cleavelandite beside the lepidolite and upon closer inspections in some of the vugs (small open spaces in the rock) there were some small quartz crystals. If you go by what the books say, things were looking mighty fine.Yes, I was excited. As I slowly cleaned off the area the lepidolite mass kept growing in size until it was over 3' long. There was montebrasite, muscovite, beryl, quartz, and the lepidolite that went from purple to green. This was the place to be. The electric hammerdrill came out in hopes of finding a pocket, but it was not meant to be. I covered it up at the end of the day and although I would expose it periodically I would not mine this exact area for another 16 months.

Shortly after finding the lepidolite mass, the folks from the Pegmatite Workshop showed up. There were between 30 and 40 people with many varied interests. From novices who knew less than I up through some with doctorates in their field of study. It was interesting to listen to some of the scientific debate on the geology of what is going on at the Berry-Havey quarry. Aside from the area I was working, it was pointed out again that some areas on the opposite side of the quarry looked promising for pocket formation. Listening to some of the different ideas  it emphasized the more you know the more you realize you don't know.
