MB,
Hope you're looking after the fish in the water feature? :(

This is their season to come alive. When we came home in November Sandra reckoned we'd lost most of them but they're back. I have the alarm set for 7:30pm when the automatic feeder dispenses a small amount of fish pellets. As the pellets hit the water Orca (the biggest) dives in and swishes the pocket of food far and wide and then everybody joins in for a frantic feeding frenzy. The new ones that we brought home a few weeks back are a bit shy but they'll learn. I have the big insect zapper right near the surface so as long as there are insects about that's their favourite food.

Whenever the water is cold they hide and don't move about much but in the hot weather they are very active.
 
I got up this morning and looked at the weather forecast. It looks like the wet is coming and very soon, perhaps by the end of the week.

That meant that I'm running out of time to blow dry dirt so I hooked up Goldilocks and headed out to the site. Mrs M crawled out of bed early and brought me back for Tonka. I dropped it off the truck, stood up the air cleaner stack and removed the transport axle halves.
 
I had my troublesome gold button analysed today.

I'm pretty happy with that but I will try to refine it further when I get the chance. It looks like lead may have been the problem and most of that was removed in the multiple melts when my friends tried to help.

Hi Phil, just wondering if you are noticing any latency issues with the Oraolo neckband headphones and if so whether you find the delay to be a problem or not. Also if there is any noticeable interference/EMI generated by the speakers when you are digging targets and presumably they are closer to the coil. I look forward to hearing your views. Cheers

Yesterday it was overcast and cool, too wet to dryblow, so I took the 6000 with the DD and swung over some of my scrapings. It was blowing a gusty wind that would have made using the original earphones howl with wind noise. The Oraolos gave a good clear sound in these conditions with considerably more volume to the ears than the inbuilt speaker.

Now the question of latency, well it's there and quit bad. I didn't realise the other night in the dark but that's the main issue I was having pinpointing with the DD coil. By the time the signal has come through the speakers I've passed over the target. Yesterday I was swinging along with the Oraolos on and then hitting the Bluetooth switch to pinpoint then turning the Bluetooth on again to sort the target from the spade because I could hear better with them on.

These speakers are suitable for sitting in Tonka listing to my storybooks but shouldn't be your first choice for metal detecting. They have no affect on the detector in relation to EMI even when I'm kneeling on the ground next to the coil.
 
Thanks for taking the time for that feedback Phil. I liked the sound of them being waterproof but might go with the low latency Anantree version.

Regarding your dry blowing setup, I've got a much smaller version - about 3t/h fed by a 2.5t excavator. I was working a rich shed that graded down to the point that it wasn't economical to scrape up and dry blow the bottom anymore. Rather than just burying it I made up a grizzly screen out of a Nissan cargo barrier which had about 20 mm mesh on it which matches the dry blower grizzly and pre-processed the dirt through it removing about half. End up with half the dirt but double the grade. It was double handling sure, but it was quicker overall, the dirt was 'better' and most importantly it halved the dry blower running time. They always want to self-destruct, and there more time you give them, the more they do...

Cheers

They sure do self destruct. I worked it Thursday morning early because we had a garden club meeting for morning tea. All went well until I returned after morning tea and fired up the little Honda. It only ran for a couple of minutes before I noticed the conveyor had stopped. I jumped off the loader and quickly shut it down. I'd recently replaced the centre conveyor roller but I checked it over and couldn't find anything wrong. Each time I started it again I could hear a bearing squealing and the Honda would stall but couldn't work out where the noise was coming from.

After running my hand over everything nothing was running hot so when I started it I pushed it up to full throttle and stood back looking for something to break It didn't so I went back to loading it and after another few minutes and a loud screeching and all went quiet. I thought whatever was jamming it had cleared but as I started to load it again I noticed there was no vibration on the classifier.

The two piece wobble shaft is supported on seven bearings one of which I replaced last week. Three more of those seven bearings spat the dummy. I don't know why it all went haywire right now but when I replaced that bearing last week these others wouldn't take any grease. I guess they were already on the way out. I was in too much of a hurry to get it all back out to the site before the wet hit to do anything about it. Now that it's raining I guess I have the time :)

I haven't found that rich patch yet. I had one stack of a few hundred tonnes that paid well but when it ran out everything else has been mediocre. Every thing I've loaded in has payable quantities of gold but nothing special. I have a lot of ground but so far every move has been no better and no worse. I'm just going to keep plugging away hoping to strike a better patch but if it keeps going like it is we're doing ok anyway.

I need a grizzly too but a bigger stronger one.

I have a few thousand tonnes of this dirt that has a decent concentration of fine gold. I was putting it through the dryblower but with the big loader you can't see what's in the bucket and some rocks were half a tonne or more tumbling off the top. I haven't worked out if it's worth building a grizzly and double working it or just putting up with the higher maintenance cost of handling the big rocks along with the rest of the dirt.
 
Another storm this evening.

Mrs M spent the day putting the greenhouse back together, this time using silicone to glue the panels in. I repaired the gazebo car cover.

Fortunately it was more rain than wind. It won't help with the dryblowing but at least it didn't blow everything apart.
 
Hi Phil, Hope things have dried out a bit for you? Check out Jason at Mt Baker Mining and Metal (mbmm) on youtube, he has some very good videos on Smelting Gold.
They may be of some help with your smelting. Good luck, cheers, John
 
Thanks John, No it certainly hasn't dried out but we were expecting the rain. It's time to do a few of those things that were put aside for later and Mrs M has quite a list ;)

I have watched quite a few of Jason's videos. I'd love to have just a fraction of his equipment but the more you invest the more you must make to keep you're hear above the water. I think he has more the enough time and money on his hands but he makes good videos.
 
I've been a bit slack on my posts lately but I have been busy....

The waterfall and rock garden is a work in progress but it's coming along.

1645615249_waterfall_1.jpg


Mrs M has lots of ideas for additions so I'll be busy for a while yet.

44C and the pond water is as cool as a cucumber.... :)

The idea is to have a shaded area with overhead misters that will give us a little respite from the severe heat on those days where we usually just stay inside with the evaporative air conditioning. It's usually quite pleasant inside but if you poke your nose out it's not for long.

We took a 90km drive up into the Weld Range where we were told of a swimming hole. The young fellow told me that it had long necked turtles so I thought if there are turtles then there are sure to be fish.

The water level was quite low so we didn't swim but after setting the fish traps we took the opportunity to clean up the glass, cans and plastic that would normally be below the water.

1645662136_rubbish.jpg


I thought we might get turtles so I left the top of the traps proud of the water so they didn't drown.

1645662278_turtles_2.jpg


This one was about 130mm across the shell.

1645662324_turtles1.jpg


We got four of my favourite size but we released them all. We didn't even see a fish so I don't know what the turtles were eating. I'd like to see these guys in the pond but if they decided to go walkabout then they would certainly die. There are no waterholes to find.
