Tinka - Ayawilca

We have seen some decent hits from Tinka's Ayawilca project in Peru.

  • 62.4m @ 5.6% Zn, inc. 17.9m @ 11.6% Zn (link)
  • 51.9m @ 10.1% Zn, 62 g/t Ag (link)
  • 18.6m @ 10.4% Zn and 52 g/t Ag (link)


  • Drilling has hit multiple high-grade zinc (with Ag credits) lenses over a ~200m length
    • officially bad tonnage guesstimate = 8Mt @ 4.7% Zn
    • including a 2.3Mt core grading 7.2% Zn
  • Early days, mineralization open to the north and south
  • Faulting may have a significant impact on size of the deposit.

I've brought the data into Leapfrog Geo (you can get the 3D viewer file from here (link), back calculated the residual grades to see how everything looks.


Multiple lenses

Silver is essentially in the same place as zinc

Lead is restricted to a few, narrow zones.

We see a number of zinc lenses, that appear to pinch-out to the NW and SE. What will be critical is what the faults (dashed black lines) do to the mineralization, are they:

  • Pre-mineralization – minimal effect, but could have some high-grade Zn (+Ag) mineralization up them
  • Post – offset the mineralization – i.e. the mineralization could be deeper or shallower
I was intrigued by the zonation (?) in different metals:

  • Zinc appears to be relatively consistent, forming continuous >5% zones between the drill-holes, but there does appear to be higher grades in the Northwest.
  • Silver - there are higher grade silver zones, several appear to be close to the northwest (left) fault, and there is a nice high-grade zone at depth.
  • Lead - minimal lead, some high-ish grade intervals associated with the NW fault, but in general the Pb levels are very low.
It does appear that the NW fault could be an important controlling structure and may have some high-grade mineralization (a chimney) associated with it. It was a shame that hole A17-059 wasn't pushed on a bit further to test this fault at depth.

Hole 58 is interesting, does it show a continuation of this zinc zone to the NW or is it a separate zone or related zinc vein.chimney associated with the NW fault zone?

I did a quick and dirty 'resource' tallying

So that is a good start, so why don't we look at the upside

A Crap doodle - i'll be updating this

You can clearly see that the zinc zone is open to the NE and SW, and will offer good potential to define a good chunk of mineralization, as this zone is ~300m wide and so far drilling has focused (6 holes - 56A was an extension of 56, so i'm counting it as 1 hole), on a 100m section.

I'm also interesting to see what hole 59 will hit. I'm not very confident (maybe a couple of narrow zones) as mineralization is pinching out towards the NW fault, and my gut feel is that this fault is an important controlling structure, which either controlled the ore bearing fluids or has offset the mineralization.

Solgold - update

DISCLOSURE - I own shares in Sol Gold. I'll try to make this post unbiased, but I want everyone to buy lots of shares so that I can make some money!

We got some news a couple of weeks ago that gave us the final results for hole 21 and a PR today with some visual results from hole 23R, 24 and 25.

Hole 23 was drilled right through the middle of Alpala and will get some great results. Holes 24 and 25 were drilled to test the SE continuation of the Alpala system. They hit ever decreasing thicknesses of gradually lower grade mineralization, which is what you would expect as you move away from the core of the system.

Here are the updated official bad estimates

  • Copper increased to 1.9Mt
  • Gold increased to 4.95Moz 
Looking good, but we see that there is a smaller increase in high grade (>0.6% Cu and 0.5 g/t Au), which is the material that will be mined via and underground block-cave operation.

My prediction:

  • Hole 21 - 925m @ 0.5% Cu, including a 400m >0.6% Cu - hole only 100m from hole 16, which hit a lot of good stuff
  • Hole 23 - being drilled, target between holes 16 and 19, so I'll expect
    • 200m >1% Cu and 1 g/t Au (@ 1,000m depth), within a 1000m zone of 0.3-4% Cu and 0.2-0.4 g/t Au


Hole 21
  • 844m @ 0.73% Cu and 0.43 g/t Au
    • inc. 670m @ 0.82% Cu and 0.51 g/t Au
    • inc. 304m @ 0.99% Cu and 0.63 g/t Au
So, I was a bit-off, sort of like my high-school review - has talent, just needs to work harder.

Hole 23 

  • 573.2m of sulfides from 563.7m depth
    • at >1.4% volume percent chalcopyrite
    • or a guesstimate grade of 0.48% Cu
  • a higher grade zone from 979.2m to the current EOH at 1136.9m
    • at >2.9 vol-percet Chalcopyrite
    • or a guesstimate grade of 1% Cu
Hole 24 - 248m @ >1.1 volume percent chalcopyrite or 0.38% estimated copper

Hole 25 - 454.2m @ >1.5 volume percent chalcopyrite or 0.52% estimated copper

I calculated the guesstimate grades by taking the volume percent of chalcopyrite and multiplying it by the copper content of chalcopyrite

so 1.4 * 0.346 = 0.48% Cu

However, it is very hard to accurately measure the grade visually, so we can use these as guide to where copper is present or absent.

NOTE: I haven't used the estimated copper grade in the tonnage calculations.

Here is the updated leapfrog model (link)


It is hard to gauge the importance of hole 24 as it is still being drilled, but from the information we're given:

  • Hit a narrow low-grade copper zone 400m away from other mineralized drill-hole
  • 248m @ 1.1 volume percent chalcopyrite or 0.38% Cu from ~740m depth.
porphyry getting thinner to the right (SE)
We can also see that hole 25 (454m @ 0.52% Cu) is also a step down from the high-grades hit in hole 21 in the core of the system. This indicates that we are moving away from the high grade core into the lower grade periphery. 

This is normal in porphyry systems - you have the thickest, highest grade mineralization in the core of the system and lower grade at the edges.

Drill-hole 23 was drilled smack into the middle of the high-grade core, so this will get some decent mineralization, but won't have a huge impact on tonnes (see section below). I will expect it to hit good copper grades until around 1300m depth. I'm going to upgrade my guesstimate to:
  • high grade (>0.8% Cu) from 980m to 1350m
Hole 23 - drilled straight through the guts of Alpala.

Camino Minerals - initial review

Camino have released some interesting results from the Los Chapitos project in southern Peru (link and link)


  • Good
    • Great result from hole CHR-002
      • but, we have grade smearing, outside the >2% zone, it drops off to 0.84% Cu, still good, but could be marginal for an open pit operation
    • Small, near surface oxide zone
    • Some other interesting targets to be tested around the property
  • Bad
    • It was a shame that they went with cheapo RC drilling option as it meant:
      • Hole 002 terminated in good copper mineralization
      • Holes 004 and 005 couldn't reach the extension of this zone.
    • Typical grade 'expansion' - the high grade (>1% Cu) is found in narrow zones surrounded by low grade (0.2-0.3% Cu).
  • Trench samples look good, but I'm skeptical of trench sampling as:
    • remember - you can bias them by sampling along a mineralized structure rather than sampling across it - the FAG will explain how you can 'improve' your trench results
Is water, or the lack of, going to be an issue?

They are drilling using an reverse circulation rig, so as they mention in the March 29th PR (link), so they will be drilling 200-300m/day and they will finish the program about now....

There are advantages and disadvantages with using an RC rig:
  • Advantages
    • Quicker - drill 200-300m per day compared to 50-100m for a diamond drill
    • A lot cheaper - ~50% of the cost (or even cheaper) of a diamond rig.
    • Doesn't need water - very useful in the Atacama desert
  • Disadvantages
    • Lower quality geological information
    • greater deviation - the holes drilled by Camino started at 45 or 50 degress, but steepened to almost 80 degrees at the end of the hole.
      • if you see any company not-surveying RC holes, that is a good sign that they don't know what they are doing and that the data from these holes are suspect as they can't accurately tell you where the mineralization is located.
    • bigger visual impact
    • require more site preparation - wider roads, larger pads
    • generally limited depth - ~300m depth is generally the deepest you can drill with RC
    • can have grade issues - smearing of grade, especially at the water table
However, for exploration, you have to balance cost, speed against geological information. We can see its limitations, CHR-002 stopped in >1% Cu mineralization, and with a diamond rig you could push the hole on (if you have enough rods) and see exactly how wide that zone is.

TL:DR: They started off good, but by using the wrong equipment, they have are not maximising the value they are getting from teh drilling (unless drilling magnetite-rich zones is the objective).

Geology Wank

Hole CHR-002, very good zone, but as the hole stoped in mineralization we don't know how wide it will be.

Follow-up holes 003, 004 and 005 intersected the upper copper oxide zone, but due to hole deviation, which is common in RC drilling, they all steepened and didn't reach the target. The irony is, this deviation was seen in holes 001 and 002 and I would have expected Camino to have modified the program accordingly, as they showed us that there was a very high probability that holes 004 and 005 would have steepened (go more vertical) and not hit the copper zone.

I'll explain it visually, I prepared this image form the original press release

  • Red line = planned hole trace (i.e. where they wanted the hole to go)
  • Colored line = actual trace of the drill-holes
  • Difference between these lines = the deviation
    • we can see that as the hole gets deeper, the hole steepens (becomes more vertical)
    • We can also see that the holes can only be drilled to around 300m - this is as far as this RC rig is able to drill at this project.
  • Magenta line = what I think hole CMR-005 will do - it will hit the upper zone (my guess ~20m @ 0.6% Cu) and not reach the copper zone.
This is from the latest presentation

bendy drillholes
Look how much blue (0.1-0.3% Cu) is included in that 44m zone grading 0.86% Cu!

so that makes them 0 from 3

So you can see how much the holes are bending by (up to 20 degrees), and that makes it hard for the company to hit the planned targets, which is the reason why holes 004 and 005 missed.

You also need to think about the how the mineralization occurs, is it:

  • flat lying bodies
  • Steeply dipping narrow zones
  • large stocks
When we look at the presentation they show us some photos of some old workings.

They look to be nearly vertical, indicating that this how the mineralization occurs at Adriana.If the deep mineralization hit in hole 002 is vertical, then that zone may only by ~ 40m thick.

I think That Camino need to rethink their drilling strategy! They need to get some diamond rigs up there to answer questions on controls and size of mineralization. Continuing to drill RC-holes will start to reduce the value the company obtained from hole 002.

I've created a quick model of the drill-holes with their sections, so you can see how all the holes relate (link).

Look at how the Magnetite rich zone changes between sections...

Trenching results

Hello, FAG here.  Camino have given us some nice photos of some green-stained rocks in the Atacama.

Azurite skies...
and some photos of some old workings

Mein Mine

I've annotated the mine photo to show how you can get Maximum Impact (tm) results from trenches.

We have 2 trenches

  • Trench 1 - running parallel/along with the copper zone
  • Trench 2 - running perpendicular to the copper zone
Which will give the 'best result' for your press release?
  • Trench 1 = 30m @ ~1% Cu
  • Trench 2 = 3-5m @ 0.6-1% Cu
The question you need to ask is:


This was covered in the IKN post, so I've just included a image of a simplified mineralization zoning in a copper deposit

So, the upper zone is primarily oxide material, it may have some native copper and copper wad that is insoluble accounting for the 25% of the material that isn't acid soluble.

However, the lower zone is high-grade, contains only 25% soluble material, I wonder if this hole hit the enriched zone and we have a lot of Chalcocite.

Grade smearing - Barkerville

Barkerville, that name seems familiar....

The big, fierce black dog is made to glow in the dark using phosphorus, chases a man, who runs in great fear and dies of an apparent heart attack?

ohh, crap, that was Peter George's crowning glory with "potential to host 40-90Moz of gold" (link, link and link).

So, you have a project and a company (the faces have changed but the name is the same) that had been pulled through a river of crap over a dodgy technical report. You would think that they would be extra specially good, and they wouldn't do some massive grade smearing, from a few narrow, ultra gfg*-grade veins and come up with a massive intercept that cause geologists to faint as their blood rushes to other parts of their bodies (i.e. not their geo-pick hand.....)

who ruined that picture of a gold sample with some yucky gurl's boobs?

*gfg = geologist's fantasy grades - think of these as Scarlett Johansson** - she exists, but there is no chance you'll ever date her, but you'll be happy to sell your mate's testicles just to have the opportunity to lick her armpit

**some people may not like SJ, they are probbaly the same people that say "I prefer silver over gold". They are wrong, and should be immediately disowned.

Holy shit, they've just raised $12.5m by flogging a 0.75% NSR on a Cariboo to Osisko.

that is one expensive Ungulate, i'm guessing that Osisko bought the balls...
Crap, wrong PR, this is the one (link) I want to talk about....

Sweet holy jebus, 54.4m @ 19.2 g/t Au - that is US$800/tonne rock, let's start mining now...


Let us look beyond the Uber-high grade intervals, like:
  • 0.5m @ 272 g/t Au
  • 0.85m @ 760 g/t Au
  • 0.5m @ 64.2 g/t Au
  • 0.5m @ 42.8 g/t Au
  • 1.5m @ 65.4 g/t Au
  • 1.15m @ 15.8 g/t Au
and look but what is the grade for the other 49.5m that they don't report? What does that run?

2.5 g/t Au

Yes-sirree, just a teeny weeny 87% drop. I mean, that is still a decent result, but it shows that 87% of the gold is in just 9% of the drill-hole.

Look at the moose, 9% is equal to it's back legs.

Grade smearing is endemic in exploration companies, heck, why didn't they make it 1044m @ 1 g/t for shits and giggles?

Taylor question

I want to ask you all a quick question, I mentioned that the different ore zones at Taylor have different recoveries.

If a deposit has very poor recoveries, should it still be allowed to state it's resources?

I've only included the Zn recovery as it forms the basis of my question.

We can see that they get very poor recovery (2.2%) from the single metallurgical sample* from the Scherrer zone.

*for the case of semantics I'm going to assume that this single sample is representative for the entire 14.3Mt resource for the Scherrer Zone.

According to the Taylor resources they have calculated that the Scherrer zone contains:

  • Indicated Resources = 6.2Mt @ 6.5% Zn, 5.6% Pb, 0.2% Cu and 2.7 oz/t Ag or 14.7% ZnEq
  • Inferred Resources = 8.1Mt @ 9.5% Zn, 7,4% Pb, 0.2% Cu, 3.1 oz/t Ag or 19.9% ZnEq

It is (according to table 14.10) the 'best' zone in the entire deposit. However, the zinc recovery in the Scherrer zone is 2.2% (table 13.5 in the PEA), is this zone still good enough to be called 'ore'?

Let us recalcalculate** the ZnEq% for this zone:
  • Ind Res = 6.2Mt @ 6.5% 0.143% Zn, 5.6% Pb, 0.2% Cu and 2.7 oz/t Ag or 8.3% ZnEq
  • Inf Res = 8.1Mt @ 9.5% 0.209% Zn, 7,4% Pb, 0.2% Cu, 3.1 oz/t Ag or 10.6% ZnEq
**I've only applied the recovery percent to the zinc grades due to a massive bout of laziness

So this now takes the Scherrer zone from being the best zone to the worst (I'm ignoring the andesites as they are so small) zone. It is still economic to mine, but this is a quick demonstration for why I believe that companies should be using RECOVERABLE metal grades when they calculate equivalent grades.

Or put it another way, imagine that AZ spent ~$400M to build the mine, they are focusing on mining the 'best' ore, which according to the resources is the Scherrer Zone. They start mining, sending ore to the mill and suddenly find that all the zinc is disappearing to the tailings dam, this will cause a few problems like:

  1. Losing 40% of their revenues
  2. Possible environmental penalties as there may be quite strict limits on the amounts of lead and zinc that could be discharged to the tailings pond
  3. those fun, high confidence inducing press releases stating that "the ore is more challenging than expected", "processing difficulties", "additional test-work required" and the like.
It sounds like I'm picking on AZ, I'm not, I just though that this was a nice and easy example of a common practice in the exploration industry, and AZ provided some decent data to show it.

Arizona PEA - quick comments and questions

So we have the Taylor PEA, it is lovely, beautiful and highly profitable. I've actually started sleeping with it, so I can absorb its awesomeness while I'll sleep, but sometimes every silver lining has a black cloud.


  • Bye bye Central, it was nice to know you
  • They managed to get virtually all of the infrastructure onto the private land, but there appear to be a few Achilles's heel
    • water pipes need to cross the public land
    • they'll need to upgrade access roads and probably power-lines that cross the National Forest Land. It could be hard to get easements
  • The recoveries used in the PEA look unrealistically high, especially as the ore close to surface has lower recoveries.
    • the good ore is deep, so the first few years production could generate 10-15% less revenues, what knock-on will this have to the NPV, IRR and payback period?
I'll pass-over the fact that they are going to dump a load of tailings on top of the Central deposit (table 14.10), and ignore that Central has been on a the mango diet that has allowed it to shed an unsightly 60Moz from slimmed down from (table 14.19) a portly 200 Moz Ag to a sprightly 140Moz. I'm guessing that mango is laxative....

Do you like the way that AZ have squeezed everything onto the private land. That was some impressive origami, they managed to get everything on squeezed into the private land.

I've added the outline of the central pit
It makes for nice and easy permitting, just a few permits for water discharge, explosives and the like, but it does mean that they will have nearly 300 feet (or 100m) of dry-stacked tailings above the main production decline and shaft, and as they don't have enough land for everything, so unfortunately, Hermosa had to go and get buried.

However, they didn't quite get everything onto the private land, just a few irritating water pipes from the various water wells that they need to supply water to the mining operations. They couldn't drill in the public land so a couple of tubes will be fine.

red circles = where there is infrastructure on public land
I'm going to ignore the work required to upgrade access roads to site and the fact that there are several public forest service roads that cross the private land to get to the National Forest land on the other side, I don't if Arizona mining can prevent access, or if they will need to build new roads to bypass their property.

But, I'm confused, I was looking at the numbers in table 22.2 (page 215), as I was playing with the numbers, and I was checking the recoveries against the results of the metallurgical test-work.

You can see that the projected recoveries vary by zone, which is perfectly normal, we have a different amounts and types of lead, zinc and silver minerals. The very poor zinc recovery in the Scherrer zone is because the zinc is in silicates, not sulfides, and cannot be recovered through flotation.

However, as you know, I like to check the following:

  • How do the grades of the metallurgical samples compare to the overall resource
    • here we have a nice range, from 2.5% - this is going to be close to the cut-off grade, i.e. the lowest grade material that can be mined economically.
  • We can also see that recoveries increase with grade
    • This is also very typical
  • Are the recoveries used in the financial model in-line with the results received from the various metallurgical tests. Recovery values used in the PEA
    • Zn = 92.7%
    • Pb = 95.4%
    • Ag = 92.4%
Here are some nice pictures to show how they compare against the projected metallurgical recoveries (tables 13.5, 13.6 and 13.7) reported in the PEA.

I've added some nice, thick red-lines to show the recoveries used for each metal used in the recent PEA. You can see that only the Epitaph ore have recoveries that match the numbers used in the PEA, for the other zones they are, in some cases a lot lower. This is where the different zones are located:

Taylor ore-zones
Is this a problem? No, if AZ are only mining ore from the Epitaph zone. Their plan is to mine 60.8Mt over 23 years, so how much ore is there in the Epitaph Zone?

Table 14.10 from the 
So, if we take all of the Indicated and Inferred resources, we have 48.2 Mt in the Epitaph zone, but that leaves us with a small, 12Mt short-fall.

Where is this this material going to come from, and why is it important?

  • Manto zone - contains oxides, won't be mined
  • Scherrer zone- low Zn recovery, unlikely to be mined
This leaves the Concha zone, which is closer to surface, therefore require less decline and shaft construction (reducing costs), but the issue is, it has lower recovery, and if it is mined first (as it is close to surface), it will means that for the first few years, they will be getting lower recovery, and therefore lower revenues, which is not what you want.

SolGold Update

DISCLOSURE - I own shares in Sol Gold. I'll try to make this post unbiased, but I want everyone to buy lots of shares so that I can make some money!

Over the last couple of weeks we've received the results from holes 19, 20R and 22 (link and link).


TL:DR version: Inline with expectations
  • Economic (>1% CuEq) mineralization is deep (~600m depth)
  • Hole 19 - drop-off in grade, as you move away from the core of the deposit (hole 16)
  • Hole 20 - clipped the edge of the deposit, didn't get much.
  • Hole 22 - Inline with expectations - >1% zone is quite narrow (100m core length)
They are having drilling issues - several holes lost before reaching target depth, and have changed contractor to resolve them.

I'm concerned about grade-smearing. When you separate out the high-grade zones, you are often left with wide-zones of much lower grade (sub-economic?) mineralization.
  • Hole 22 - 730m @ 0.52% Cu and 0.23 g/t Au becomes
    • 100m @ 1.1% Cu and 0.57 g/t Au
    • 630m @ 0.43% Cu and 0.176 g/t Au
  • Hole 19 - 1344m @ 0.44% Cu and 0.28 g/t Au becomes
    • 552m @ 0.68% Cu and 0.45 g/t Au
    • 792m @ 0.27% Cu and 0.16 g/t Au
This shows we have a high-grade (>1% CuEq) core surrounded by lower grade mineralization, which is normal for porphyry systems.

TAG Officially Bad (tm) resources

  • Au - increased to 4.74Moz (542Koz or 13% increase)
  • Cu - increased to 1.7Mt (198Kt or 28% increase)
looking good...
The key is going to be the cut-off grades that are used to calculate the resources.


  • Hole 21 - 925m @ 0.5% Cu, including a 400m >0.6% Cu - hole only 100m from hole 16, whihc hit a lot of good stuff
  • Hole 23 - being drilled, target between holes 16 and 19, so I'll expect
    • 200m >1% Cu and 1 g/t Au (@ 1,000m depth), within a 1000m zone of 0.3-4% Cu and 0.2-0.4 g/t Au
  • Hole 24 - keep an eye on this one, 3 scenarios (2 good and 1 bad)
    • Gets not much as it is drilling the peripheral part of the Alpala porphyry (i.e. lots of pyrite and not much else)
    • Drills deeper and hits the continuation of the Alpala porphyry
    • Drilling the peripheral part of the mineralization mapped at Malte Creek
  • Hole 25 - being drilled ~100m south of hole 19, so I'm estimating
    • 600m @ 0.3% Cu and 0.2% Au
    • drilling below hole 003 that hit a couple of narrow zones @ ~0.3% Cu and 0.1 g/t Au

The Good

Hole 19 hit reasonable mineralization, inline with what you would expect when you are drilling away from the high-grade core in holes 12 and 16. 

left = split assay results; right = super duper PR assay results
Hole 24 is going to be key, from the description (lots of pyrite and trace chalcopyrite and bornite), it suggests that it has intersected edge of a porphyry, but is it:
  • Part of Alpala system - they've extended it by >1km, which is huge, this could move Alpala into a >10Moz Au deposit
  • If it is associated with Malte Creek target - a separate, smaller Cu-Au system. Good.
  • If it is the distal part of the Alpala system - nothing changes
Gut feel - the middle one, we'll have to wait for the results to see what grades they get.

The Bad

Hole 20 appears to have clipped the edge of the Alpala system. Even though the hole was lost, I doubt that it would have got much more, so it basically tells us that the exploration potential to the east is less than thought.

left = split assay results; right = super duper PR assay results

I did enjoy the lip-sticking (applying lipstick to tart up some average results), done by the IR department, but Hole 22 (designed to see if the Cu-Au zones goes to surface) was a classic Playtex (tm) hole - looks great from afar, but once you get it open, everything disappears.

geoporn is always crap
However, the results from both  are what I would expect from holes that are drilling the edge of the system. We are seeing a gradual decrease in Cu and Au grades away from the center of the system (around hole 16).

left = Copper; right = gold
you can download the 3D view from here (link)

The Ugly

Sol Gold are drilling 1500-2000m drill-holes. So each hole will take 2-3 months to be drilled (I'm assuming 800-1000m per rig each month). You can now see how important it is to use decent drilling contractors, as you don;t want to have invested >$100K and more importantly time into a hole that is lost before it hits the target!

Losing a couple due to poor ground conditions is expected, but the fact that Sol Gold tell us that they have changed contractors suggests something more - maybe they were using old equipment and inexperienced drillers?  


When you split out the high-grade intervals you see that the best mineralization is deep (starting at around 600m) with a high-grade core that grades outwards into lower grade mineralization. For me, the key is to keep your eye on the 0.7% CuEq contours that SolGold put on their various sections. Fe me, this is a reasonable proxy for the economic limits of mineralization. If you carefully check Figure 6, you can quickly see the disconnect between the long mineralized intercept reported in hole 22

So essentially SolGold have given you a quick way to check their results and ignore the PR headlines and look at what the data is telling you.

What I would like to see

Some work on the other targets, it would be nice to know when they will be thinking about drilling the other targets. Alpala is now a mature exploration project and the new results aren't as flashy as earlier ones and people will start to get Alpala fatigue. It will be nice to have a rig exploring adjacent targets, as Sol Gold could find higher grade zones at surface where there will be amenable to open-pit mining.
