Reachable Buyer Map

Prepared for Frederico Rosendo · Spokane Industries · September 2026
Here is the map Guilherme promised. Your own site sets the boundaries for it: four product families, two foundries on one site in Spokane Valley, and castings built to survive abrasion, impact and heat. So this page takes those four families and splits the US market into the groups that can actually buy from each one, and for each group shows who owns the decision and roughly how many organizations exist. It maps the market around Spokane Industries, not Spokane Industries. One group has no honest public count and another has only a floor, and the page says so rather than showing you a number. There is nothing to buy at the end of it.
Where the decision sits
Seven rows. The first four are counted from the federal mine register, the fifth from the federal business register, and the last two cannot be counted honestly from either. Read the two figures on each row separately: one counts operations, the other counts the company named as controlling them. One warning that applies to every row below. The register names the company that carries safety responsibility for an operation, which is a legal fact and not a commercial one. It is a good way to see the shape of an industry and a poor way to find a buyer, and at the large groups the person who actually specifies a wear part sits several layers below the name on the permit.
Sand, gravel and crushed stone producers
The volume base for your aggregate wear parts, and the row where the site count misleads badly. There are 9,469 live operations on the federal register and only 4,389 companies named as controlling them, and that company list has three distinct tiers rather than a head and a tail. Seventy-six companies hold 2,673 of the sites between them, and the four largest hold 1,056 on their own: CRH, Martin Marietta, Vulcan Materials and Heidelberg Materials. Another 1,152 companies hold between two and nine sites each, 3,585 sites in total, and that is the regional tier most likely to be reachable and most likely to be ignored. Then 3,161 companies hold exactly one pit. The same blow bar sells into all three and none of the three buys the same way.
Who decides: at a single pit, the owner or the plant manager, and it is usually one conversation. At a regional producer, a maintenance manager with a purchasing function above them. At the largest groups, a supply agreement negotiated centrally and then drawn against by sites that had no say in it, which means the register tells you the group to research and not the person to call.
What the register cannot tell you: which of these run impact crushers rather than cone crushers, which is what decides whether they buy blow bars at all. That is a plant by plant question and it is the first filter worth building.
9,469 operations
under 4,389 named controlling companies. Sand and gravel pits and crushed stone quarries, each operation counted once, with cement, lime and dimension stone taken out into their own rows below. Fifty operations carry no controller name.
Metal mines
The row your mill liners, wear plate and gyratory concaves sell into, and it is not a market, it is a list. 248 live operations in the entire country, under 164 companies, and gold is more than half of it at 136 operations. Iron ore and copper are 25 each. Nevada holds 54, Alaska 44 and Arizona 24, which is 122 of the 248 in three states. Washington holds exactly one, the Pend Oreille zinc mine north of Newport, and across Washington, Idaho, Montana and Oregon together there are 25. This is the highest value casting on your product list and almost all of the buyers are a flight away, which makes it an account plan with named companies in it rather than an outbound exercise.
Who decides: the mill or maintenance superintendent at the operation specifies the liner, and at anything owned by a major the purchase runs through a corporate supply chain function that qualifies suppliers before a site can order. Getting qualified and getting specified are two different jobs with two different people, and doing them in the wrong order is the usual way a foundry loses a year here.
248 operations
under 164 named controlling companies. Gold 136, iron 25, copper 25, lead and zinc 9, zinc 7, silver 6, and the remainder in ones and twos. No operation in this row lacks a controller name.
Cement and lime plants
The most concentrated row on the page and the one most often left out of an aggregate plan, even though the crushing and milling circuits consume the same wear parts. 169 operations, 61 companies, and five of those companies hold 56 operations between them. A cement plant is a long qualification and a long relationship, and there are few enough of them that every single one can be named and tracked by hand. Texas holds 16, Pennsylvania 11, and Alabama, California and Missouri 10 each. Washington, Idaho, Montana and Oregon hold nine between them.
Who decides: the plant maintenance manager owns the wear problem, the plant manager owns the downtime it causes, and a group procurement function owns the approved supplier list that both of them have to order from.
169 operations
under 61 named controlling companies. Cement and lime operations on the federal mine register, each counted once.
Coal operations
Included because the register counts it cleanly and the wear parts overlap, not because it is a growth market. 609 operations, 239 companies, and it is a regional business rather than a national one: West Virginia holds 185, Pennsylvania 174 and Kentucky 84, which is 73 percent of the country in three states. Nine companies hold 184 operations. For a foundry in Spokane Valley this row is a long way from home in every sense, and it is on the page so that leaving it alone is a decision rather than an oversight.
Who decides: the same pattern as metal mining, a site maintenance function underneath a corporate approved supplier list, with the added feature that the operator and the controlling company are frequently different businesses.
609 operations
under 239 named controlling companies. Bituminous and anthracite, surface and underground, each operation counted once.
Equipment makers, for the OEM casting line
Your OEM steel castings sell a part number rather than a replacement, which makes this the row with the best repeat economics and the worst public data. The closest honest public figure is 911 establishments: 252 in mining machinery and equipment manufacturing and 659 in construction machinery manufacturing. Treat that as a floor and not a market size. An equipment maker that buys a frame, a housing or a drive component may be registered under a dozen other manufacturing codes, and the register counts the company, never the engineer inside it who specifies a casting. In the four states around you there are 48 of these establishments, which is a short enough list to work by name.
Who decides: a design or project engineer specifies the casting and effectively picks the foundry, and a supply chain or sourcing lead places and re-places the order afterwards. Winning the engineer and winning the buyer are separate campaigns and most suppliers only run the second one.
911 establishments, a floor
252 mining machinery and equipment manufacturing, 659 construction machinery manufacturing, from the federal business register. The real OEM buyer population is larger and is spread across codes that cannot be separated out.
Investment casting buyers
The one this page genuinely cannot count, and the honest thing is to say so. No federal register enumerates companies that buy small close tolerance steel components, because that is a purchasing behavior rather than an industry, and the buyers sit across defense, energy, food equipment, pumps and valves, instrumentation and a long tail besides. Anyone who hands you a number for this segment has built it from a list they bought, not from a register. It is reachable, just not countable, and the only way to size it is to work backwards from the part geometries your second foundry is actually good at.
Who decides: the same engineer and sourcing pair as the row above, at a company that may never appear in any mining or construction list.
No usable public count
Deliberately not estimated. There is no registration category anywhere in the federal files that isolates this buyer.
Dimension stone and other industrial minerals
The remainder of the mine register, and worth one row rather than none. 1,621 operations under 1,021 companies: dimension stone at 743 operations, and industrial sand, clays, gypsum, bentonite, salt, phosphate and the rest at 878. Individually small, heavily single site, and mostly running smaller equipment than the aggregate row. It is the row to reach with a catalog and a standing quote rather than with a named account approach, because the cost of selling to each one is close to the value of what each one buys.
Who decides: overwhelmingly the owner. Four hundred of the dimension stone companies hold exactly one operation.
1,621 operations
under 1,021 named controlling companies. Dimension stone 743 operations, other industrial minerals 878.
The same map by state
The largest aggregate states, with your own four included wherever they fall. The columns count different things and do not sum across. Read the metal column beside the aggregate column: the two businesses are in different places, and that is the geography problem on this page.

Where the openings are

1
The aggregate market is three markets wearing one name. Seventy-six companies hold 2,673 sites, 1,152 companies hold between two and nine, and 3,161 companies hold exactly one. A single message aimed at all three loses the top tier on process, because they buy through a supply agreement nobody at the pit controls, and loses the bottom tier on attention, because the owner answers his own phone and does not read a supplier campaign. The middle tier is the one worth building first: big enough that a wear part decision is worth real money, small enough that one person still makes it.
2
Your highest value castings sell into a list of 248, and one of them is in Washington. Metal mining is small enough to name in full, which means the entire segment is a spreadsheet rather than a funnel, and the work is qualification and specification rather than lead generation. Nevada, Alaska and Arizona hold 122 of the 248. Deciding whether that is a business you fly to or a business you leave to the equipment makers who already serve it is a strategic fork, and it is better decided deliberately than by whichever inquiry happens to come in.
3
The two rows with the best repeat economics are the two rows no register can see. OEM castings and investment castings both sell a part number that gets reordered, rather than a wear part that gets consumed, and both buyers are invisible in public data: 911 establishments is a floor for one and there is no honest number at all for the other. Everybody selling into those rows is working from the same blind register, so the advantage goes to whoever builds the named list first rather than to whoever buys the best data. That is a build, and it is the single highest value piece of work on this page.
Built from the federal mine register, file dated 18 September 2026, all 92,017 records read, and from the federal business register, 2022 state file, read in full. Mine counts include operations currently listed as active, intermittent or new, and exclude abandoned, sealed, idled and nonproducing sites. Operations are classified on the register's own canvass field rather than on commodity text, and a further 239 live operations carry no classification at all and sit in none of the rows above. An operation is not a company: the company figures count the entity named as controlling that operation, which is a safety responsibility rather than a purchasing one, and operations with no controller name are reported separately rather than grouped together. The mine register and the business register disagree on the size of the aggregate market, because a permitted pit and an establishment with payroll are different things, and this page uses the mine register with that caveat rather than the flattering one. Every figure here is a direct count of a named register on a named date rather than an estimate, which makes it reproducible and does not make it the size of your market. A registration proves enumeration only, never activity or fit, and a segment with no credible public number says so here rather than showing one.
