There's a part of an underground mine that seems to be caving in slowly (with my eyes) in a workshop but I've only worked in this mine for 3 months. It's reinforced with split sets and mining mesh but I still don't trust the structural integrity of it. Any words if advice front the experienced?

Besides the mandatory safety equipment and PPE. What would you recommend carrying during a shift underground?

Hello Reddit,

Wanted to share a breakdown of a recent 310-tonne CIP leaching run on gold tailings that didn't go to plan financially.

The initial setup & budget:

-Feed purchased: 310 tonnes of tailings @ 3.3 ppm (Au)

-Ore cost: 90,000,000 TZS (~$33k USD)

-OPEX (chemicals, labor, water, power): 35,000,000 TZS (~$13k USD)

Total spent: 125,000,000 TZS (~$46k USD)

The output:

-Dore bar 1: 379.5g @ 89% purity (~337.8g fine gold)

-Dore bar 2: 59.7g @ 35% purity (~20.9g fine gold)

Total recovered fine gold: 358.65 grams

Recovering only 358g of pure fine gold against 930g contained in the raw feed was a disaster (38.5% total recovery). Testing the tailing solids post-clearing showed a grade drop from 3.3 ppm down to 0.8 ppm (~75% recovery).

The 0.8 ppm tail proved cyanidation worked. We actually dissolved around 750 grams of gold out of the rock into solution. Our failure happened completely downstream.

Carbon over-saturation and fouling: assays on our 350 kg carbon batch showed a pre-elution grade of 693 ppm Au and a massive 1,099 ppm Cu. High copper co-extraction loaded our carbon early, limiting its gold pickup capacity and leaving dissolved gold un-adsorbed in the barren solution.

Smelting and slag entrapment: The high copper content contaminated the melt. A cross-section of our slag showed distinct layering: light silicate glass on top, green copper silicate in the middle, and a heavy dark copper-iron matte at the bottom that probably scavenged fine gold prills right out of the melt.

We basically just made our investment back.

Curious to hear from any metallurgists or CIP operators here of their experience.

I'm in Africa and building my network in the commodities trade, with connections to suppliers across minerals such as lithium, gold, chrome and manganese.

I'm also learning how established platforms and broker networks connect listed supply opportunities with genuine buyers and investors.

For those already active in the industry, what channels have worked best for sourcing verified buyers? How do you qualify buyers and avoid wasting time on intermediaries without mandates or proof of funds?

I'd appreciate practical advice from experienced traders and brokers.

I am an Australian-Zimbabwean who has been building connections with geologists in Zimbabwe around critical minerals like lithium, antimony and platinum. Looking to connect with anyone who has experience bridging African mining opportunities with Asian investors. Happy to share more about what I am seeing on the ground

Im looking at an open Manager position in one of Glencore's Congolese operations. Im unsure about the pay and how it is structured. Google seems to be quite sparse on details. Does anyone have any insight?

Anyone ever worked out there for Rio? Shifts are 4:2 but not much precise info online about expected annual pay.

G'day legends,

I've been asked if I'd be keen on a jaunt to Mauritania for 4 weeks to check out a few things.

The Australian government has the capital under a level 3 travel advisory, and the rest of the country is a level 4.

I'm keen on the adventure, but I'm not super keen on being beheaded by some offshoot of Boko Haram.

Those of you who have worked in Mauritania, is there anything to consider before heading off? Anything to be mindful of? Anything I should make sure the client is organising and sorted out before jumping on a plane? Like work permits for example

Iam mining engineering fresh graduated, just wondering to know the easiest way to get to canada ? Without high cost or accepting a grant .

Knowing that my plan is to have primitive experience (6 month -1 year )In my country sudan to relate and connect what i study togther and so as the experience support my path of travel as well.

Does also any one have information about mining companies jobs in soudia arabia?

Need more advices for field training-get more opportunities and develop my career quickly

Looking for some advice.

I work as an environmental advisor/specialist/manager and am looking to get back into expat work.

Australian currently working FIFO in Australia and have worked in Indonesia as an expat in mining also.

Where is best to break into the expat mining community in Middle East or Africa ?

Any help would be greatly appreciated. Thank you

Hey, im a mining engineering student in Botswana. Im currently considering extracurricular activities and auxiliary skills to add to my cv and make me more attractive as an employee when i graduate. Are there any particular skills or fields i should focus on? Im also quite skilled and interested in working with computers, is there some way to specialise in computers as a mining engineer?

Anyone here done a stint with them? How was the mine site and camp? Anyone worked in their mobile maintenance department?

I’m in a situation with my company where I might have to look into a solar system instead of normal power. My mine is a start up basically. We are mostly running pumps for leaching tanks & pumping water. We wanted to go full milling & get a heavy 40 beater hammer, a 3 tonne Boremill.

Is there a solar system that can allow me to run these machines plus lights & a deep freezer( I can do a solar one on this). Any assistance would be appreciated.

I operate a small-scale gold mining site in Tanzania with active production and verified quartz ore.

I am seeking an investor specifically to fund equipment upgrades (crusher, mill, and processing instruments) to increase tonnage and recovery efficiency.

Current operation is running but limited by machinery capacity. Expansion potential is clear.

Open to:

• Profit-sharing agreement

• Equity partnership

• Structured return on investment

Serious inquiries only. Documentation and operational details available upon request.

Anybody who has worked in Africa care to shed some light on it? I’ve received a few job offers to work long fifo swings in Africa and the pay has never been all that great.

Are people really leaving residential or in country even time rosters for like 25% more pay to work a way worse roster?

I have always wanted to work in Africa as a career goal but it’s not something I can justify to my family to be gone 3 quarters of the year and bring home not much more money.

Hi everyone

We are a supplier based in Southern Africa (Namibia) offering high-volume limestone suitable for large-scale industrial use.

Hey guys! Been in the underground mining industry for a while, I’ve recently just got a job over in Botswana.

Just wondering if anyone has any hot tips on what I should be bringing over with me?

Or any other helpful hot tips,

Cheers fellas

I’m currently operating a licensed small-scale gold mine in Chunya District, Mbeya Region, Tanzania, and I’m looking for a partner or investor to help scale up production capacity.

Project Overview: • Location: Chunya, Mbeya, Tanzania • Stage: Active and licensed small-scale operation • Ore grade (Au): Ranges between 1.0 – 7.0 g/t based on multiple rock samples • Processing method: Carbon absorption system currently in use (gravity + adsorption) • Throughput: Around 10 tons per week • Expansion goal: To improve processing plant efficiency, increase daily throughput, and optimize gold recovery • Investment model: Flexible — open to profit-sharing, gold-based returns, or equity participation

We have all required permits in order, and I can provide assay reports, geological data, and site photos for serious inquiries. This is a real, producing site — not an exploration proposal.

If anyone here has experience in small-scale or mid-tier gold operations and is interested in a hands-on partnership or investment, feel free to DM me. I’m open to transparent discussion and collaboration.

I'm hoping someone who has looked into both these companies before could give a short rundown on what the combined operations would look like.

I'm trying to do a realistic comparison between Heliostar and the combined entity.

From what I gather both Heliostar and the PDI merger plan to have around 400k ounces production of gold annually by 2030.

Heliostar trades at quite a discount to the merger, $700M CAD compared to an estimated $2.7B AUD (4.5B shares @ .60 AUD) (1 CAD = 1.07 AUD).

Heliostar aims for sub $1300 aisc.

Kinda trying to figure out what I'm missing, I've only been looking at mining companies for a few months. 👍🙏
