70,000 meters completed, highlights include:
349.0 m of 0.77% Cu , including 232.0 m of 0.86% Cu (AZ23292)

TORONTO, May 16, 2024 (GLOBE NEWSWIRE) -- McEwen Copper Inc McEwen Mining Inc. (NYSE: MUX) (TSX: MUX), is pleased to provide the assay results from the currently completed drill season at the Los Azules project in Argentina. The prime objectives of this season’s infill drilling campaign were: 1. to confirm the size and grade of the deposit as compared to the 2023 PEA estimate and upgrade the resource categories for the upcoming feasibility study; 2. test for extensions of mineralization beyond the current pit shell; and 3. explore our large property package for other mineralized areas.
Based on the assay results received to date, our first objective appears to have been met. Initial interpretation suggests that our infill drilling will result in an increase in Measured and Indicated resources and an overall mineral inventory within 5% of the PEA estimate. Testing for extensions beyond the planned pit has successfully encountered mineralization both to the north and to the south. Primary mineralization was intercepted (202.0 m of 0.20% Cu) over 400 meters north of last year’s deep exploration hole, confirming its extension at depth a significant distance to the north. Exploration south of the planned pit has intercepted the principal mineralized intrusive more than 700 meters south of previous drill intercepts and indicates that prospective intrusives continue well to the south of the pit.
Exploration over our property has produced an intriguing target, late in the season. Initial results of a concession-wide regional mapping and sampling campaign have identified strong evidence of a large porphyry system 3 kilometers east of the Los Azules deposit. Porphyry-style veining and quartz vein stockworks with copper oxide mineralization have been recognized within this new target, with assay results pending.
Additionally, this news release covers all results from the first half of the 2023-24 drill program (see Table 1 ). Final results will be published when all the geochemistry is completed.
The objective of the 2023-2024 drilling campaign is to collect all the necessary information to support the completion of the Los Azules Feasibility Study by early 2025. This information continues to arrive and will be processed in the following months. Resource drilling is focused on converting all the mineralization to be mined in the first 5 years to Measured and Indicated resource, to increase confidence during the payback period. Geotechnical, metallurgical, hydrogeological, exploration, and condemnation drilling are also being performed.
Highlights

• Hole AZ23292 returned an intercept of 349 m of 0.77% Cu (approx. true thickness). The Enriched zone portion of this hole extends over 346 meters and includes an intercept of 232 m of 0.86% Cu
• Hole AZ23277 has an intercept of 382.5 m of 0.54% Cu (approx. true thickness). The Enriched zone portion of this hole extends over 306 meters with a grade of 0.61% Cu and includes an intercept of 74 m of 0.86% Cu

Results
Results are summarized in two schematic cross sections ( Figures 2 and 3 ), which include simplified interpretations of the Overburden, Leached, Enriched and Primary zones. The Enriched mineral zone refers to the enrichment of a copper deposit by precipitation-derived water circulation that carries copper minerals downward through the rocks to accumulate in a thick, often horizontal “blanket”. Immediately above the Enriched zone is the Leached zone, from which copper was removed and transported. Weathering and oxidation often aid in this process. Below the Enriched zone, the Primary (or Hypogene) zone is formed by ascending copper-rich fluids having a much deeper magmatic origin. The green line on the sections indicates the pit floor of the 30-year pit shell from the 2023 NI 43-101 Preliminary Economic Assessment (PEA).
Figure 1 presents a plan view of the location of two sections and the holes reported. Adjacent cross sections are located 50 m apart from each other, starting with the lowest numbered section at the south end of the deposit and progressing to the north.

Growing the Deposit
Exploration hole AZ23241 ( Figure 4 ) intersected a long interval of low-grade mineralization in the Primary Zone ( 202.0 m of 0.20% Cu ) and began to enter higher-grade mineralization at the end of the hole ( 12.0 m of 0.44% Cu ). This hole is located completely outside of the 2023 PEA base case mineable pit shell. This hole is over 400 meters to the north of exploration hole AZ22174, also located outside of the 2023 PEA base case mineable pit shell, which encountered 1,052.0 m of 0.29% Cu including 480 m of 0.42% Cu ( Figure 4 ). These intercepts suggest that primary mineralization continues at depth a significant distance to the north. Exploration drilling south of the deposit has extended the presence of the early mineral porphyry more than 700 meters south of previous drilling and well outside of the southern pit boundary. This porphyry is host for the majority of the mineralization at Los Azules and encountering it a significant distance farther south indicates that the deposit may also continue in this direction. Assays for these holes are pending.
A comprehensive structural model for the deposit has been completed that will provide a better understanding of structural controls on the deposit and aid in future exploration work. Field verification of a previous property-wide structural study using satellite information was carried out in January and has refined the identification of nearby exploration targets.

Indications of Another Porphyry Copper System Nearby
To date, geological mapping and geochemical sampling has been focused primarily near the Los Azules deposit and only covers roughly 40% of our large concession. To address this limitation, a mapping and sampling campaign was begun in December, to obtain 100% coverage of our concession.
Early results of this work have identified a large new porphyry system 3 kilometers east of Los Azules. Preliminary work has identified porphyry-style veining and alteration, indicating the presence of a porphyry copper system. Areas with strong quartz vein stockworking and the recognition of copper oxides at surface add to the prospectiveness of this newly identified area ( Figure 5 ).

REPORT AN ERROR

Hi all thank you in advance for your help. My coworker was selling homemade burritos today & I decided to buy one for lunch.
My estimate is this, using myfitnesspal entries: Tortilla 70g: 166 cal 3/4 cup of ground beef, cooked: 315 1/2 of a Winnie : 60 cal Slice of bologna: 90 cal 1/2 link of chorizo: 45 cal Which is a total of 676 calories.
I think the ground beef might be a little overestimated because the burrito didn’t have a huge amount of filling at all, but what do you guys think? Thanks again.
Sorry if the picture is not the best, I tried to take it discreetly in the break room lol

If you have an Aquila X3 Series, with the auto bed leveling system, you might want to copy / bookmark this post somehow. I am going to discuss the all too common problem of broken or at least overly tight wires into the OEM proximity sensor for the Auto Bed Leveling system, and what to use and how to fix it. I am open to better / easier ways of fixing this, but I am trying to go for a full on proper fix, not a bubble gum and duct tape approach.
So my new a week ago Aquila X3 Max was delivered with a bad sensor, or more specifically the sensor was installed so tightly the wires going into the sensor were pulled and not making good contact all the time.
So the symptom I had was pretty straight forward. The hot end and Z axis bar or whatever you would call it, upon power up would simply raise up about 4cm or so, auto home, same thing, auto level, would just say auto level completed. Nothing was working right, and no light on the sensor at all. Bit giveaway we have a problem.
I am able to futz with it to get it working, but that is not a proper fix. However since this is a new machine, I do not want to take any actions that might invalidate the warranty, and I have it rigged now so that it works and has since about Saturday (4 days after getting, setting up and testing the machine). I have so far gotten 4 successful prints out of it (Raspberry Pi 5 / Pimoroni NVME base cases) and aside from I can't figure out how to get PETG to stick to the build plate (PEI) I think we are all good.I may put off repair until it completely goes toes up again.
How I got it working again at least temporarily.
In my case, I noted the sensor wiring was installed WAY too tightly and once the sensor was unbolted and the tension came off the cable it lit right up. I snipped the zip tie holding the wiring bundle to the hot end carriage and then just sort of back pulled a couple of MM of cable, reinstalled the sensor, tested again, still lights up, put the cover back on, no more light, no function, take the cover off, and pull a bit more of the wiring in, giving it a slight curve into the sensor. Light comes back on, put the housing back on with it powered up, light stays on, screwed the housing back together fully. Light stays on. and then ran an auto home / auto level and it worked well, although the Z offset is kind of high and requires a goodly amount of futzing once the auto level is done. I typically have to set Z offset to -1.20 or so. That sensor is NOT far enough away from the bed but I can work with this.
It IS possible that the excessively tight pull on the wires at the sensor were pulling things out of contact in the sensor, and relieving this stress actually fixed the problem, but if not, a proper repair would be to replace the sensor and wire.
Unfortunately according to Voxelab support they do not have the sensor for the X3 Max in inventory, and a cursory review online shows that this issue and lack of inventory also effects the X3, and X3 Plus models.
Someone here linked a sensor on I think it was Alibaba or something like that, for a PL-042N, after looking on line at photos of the actual sensor and verifying what is actually installed, it is a PL-052N.
I honestly have no clue what the differences between the two part numbers is, but might as well go like for like right?
I have included a quick shot of the factory installed sensor, the image has been flipped so the text goes the right way to be able to read it...
After doing some searching for PL-052N online, I found lots of them, but the most affordable after you consider shipping, unless I am going to buy more than about 4 or them, is on Amazon. https://amzn.to/4by4hDe (That is my Amazon Affiliate link, but please look around, I do not post affilate links unless I cannot find a lower price, and if you do find a lower price after shipping PLEASE post a link!)
I have included a quick shot of the replacement item as well.
The replacement unit comes with an over abundance of wire so the added length needed to get to the main board compartment isn't going to be a problem at all.
Now for the debate. I can make this printer work on the OE sensor by futzing with the wire, and just run it until it actually finally poops out, or I can attack the job of replacing it now.
The process is going to be a bit of a pain because of the way the wiring harness is run. The top end of the harness has to MOVE since, well the hot end moves as well as the Z axis blah blah blah, you get it, so my plan of attack is...
Pop the heat shrink off of the ends of the loom cover wherever it may be.
Note the locations, and pop the zip ties off.
Identify the sensor wires which should be in their own sleeve on the bottom of the printer where they come out of the loom.
Unbolt the existing sensor.
Clip the wires going into the existing sensor. Cut back the sleeve about 1" and twist the old and new wires together. A few windings of electrical tape and I should be able to back pull the wire.
CAREFULLY back pull the sensor wire. leaving a small bit of slack / gentle curve under the hot end cover. Zip tie hot end wiring bundle to carriage.
Under the machine, perhaps in the main board compartment, cut wiring harness to original sensor before whatever the component inline motherboard is. Size and cut the wires coming from the new sensor, match them up, get heat shrink tube in place, solder and heat shrink each wire as needed, heat shrink the bundle.
Power up and test, if successful and I don't see why it wouldn't be...
Using heat shrink tape, not sleeve, replace heat shrink on the ends of the loom.
Replace zip ties, clip the flag ends and be a decent human being and using a lighter singe the sharp edges of the cut off so going into to service it again at some point I don't gash my arms or hands up...
So far as the images are concerned, the Heschen marked sensor is the one from Amazon, the NUOQI marked sensor is the one installed in the machine and the ones I see in photos other users have posted having the same issue.
Replacement sensor from Amazon.
Original sensor.
