Silica/HPQ

Silica/HPQ is the one OSM Core Resource with no published data of any kind. Osmond names it as a strategic interest; no silica grade, assay, concentrate result or testwork has been reported for Orion. That is the whole of the record, and this hub states it rather than working around it. What the family is about is high-purity quartz - not silica sand, which is among the most abundant materials on earth, but the narrow traded product defined by what it lacks. Orion has no JORC-compliant Mineral Resource or Reserve for any mineral: exploration results and mineralogical estimates only, with a maiden MRE and Scoping Study pending, targeted Q3 CY26. Nothing on this page describes a quantity, a presence or a prospect at Orion.

Osmond's own categorisation of Silica/HPQ as a strategic interest; shared JORC status and MRE/Scoping Study timing; general definition of high-purity quartz as a purity-specified product.

High-purity quartz is specified in the opposite direction from every other resource on this site. As a general matter of the industry, what separates HPQ from ordinary quartz sand is impurity level rather than abundance: the specification is written in parts per million of contaminants, and it is that ceiling, not the silica content, that decides whether a deposit qualifies. Aluminium, alkali metals, iron and titanium are the elements that matter, and they matter at levels far below anything a mineral percentage would record. This is a general property of the traded product, not a measurement of Orion material. No impurity analysis for Orion quartz has been published, so nothing here can be applied to it.

Orion's heavy minerals sit in a lithified tidal-sand placer - a heavy-mineral placer since cemented into a weakly laminated quartzite of the Pochico Formation, in Jaen Province, Andalucia, Spain. That host rock is quartz-rich by definition, and it is published. It is also not a silica resource, and the distinction is the substance of this section rather than a caveat on it. A quartzite host tells you the rock contains quartz; HPQ is defined by the impurities it does not contain, and no impurity analysis of Orion quartz has been reported. Reading a resource out of a host-rock description would be derivation, and the gap between the two is exactly where a silica claim could be manufactured. It is not made here.

Exploring for high-purity quartz asks a different question from exploring for anything else on this site, and the difference is not one of degree. In general industry practice a drill programme is designed to find concentration - more of the wanted mineral per tonne - but quartz is already abundant, so an HPQ programme is designed to find a rock whose quartz carries few impurities and, just as importantly, impurities of a removable kind. That turns the toolkit over. Trace elements are measured at parts-per-million level on purified splits rather than as percentages on whole rock; cathodoluminescence and fluid-inclusion work are used to see where the contaminants actually sit; and the decisive test is not an assay at all but a laboratory purification run, because a sample that cannot be cleaned in the laboratory will not be cleaned in a plant. An HPQ exploration result is therefore closer to a beneficiation result, and it arrives late - which is why deposits in this family fail after years rather than after a first pass. None of that has been done at Orion. No silica-specific exploration has been reported, no purified split has been analysed and no purification testwork on Orion quartz exists. The drilling programme and channel sampling that are published are a heavy-mineral programme: the quartzite host was logged and described, and the assays reported from it are for titanium, zirconium, hafnium and the rare-earth oxides. Nothing in that programme measures quartz purity, and nothing in it can be read as though it did.

General industry characterisation of HPQ exploration as a purity-and-removability problem rather than a grade problem, and of the analytical methods used, flagged as general in-sentence; shared host-rock description and the published assay suite for Orion, which covers titanium, zirconium, hafnium and the rare-earth oxides and contains no silica or quartz-purity determination. The absence of any Orion silica exploration is stated as the record, not inferred from it.

Mining for high-purity quartz is small, selective and unusually preoccupied with cleanliness. In general industry terms the tonnages are modest by any mining standard, because world demand for the refined product is small, so these are quarry-scale operations rather than bulk mines - and the deposit types that supply them are typically pegmatite and hydrothermal vein quartz, bodies with sharp boundaries that reward selective extraction. The operating problem that follows is unlike any other in this publication: the mine itself is part of the purity specification. Dilution with wall rock, contact with steel, hydrocarbon spillage and dust drifting in from surrounding ground are all contamination, and blasting, handling and haulage practice are chosen around avoiding them rather than around cost per tonne alone. A deposit can qualify in the laboratory and be spoiled in the pit. Nothing of the kind is described for Orion, and the absence runs deeper than the usual one. Osmond has published no mining method, rate, schedule or capital estimate for the project in any form, and nothing at all that is specific to silica: no silica target has been delineated, no silica-bearing body has been described as a mining unit, and the published host-rock description is dealt with under Occurrence, which is where the distinction between a quartz-bearing host and a silica resource is set out. Orion has no JORC-compliant Mineral Resource or Reserve for any mineral, and a maiden MRE and Scoping Study are pending, targeted Q3 CY26.

General industry characterisation of HPQ mining as small-scale, selective and contamination-controlled, and of pegmatite and hydrothermal vein quartz as the usual host types, flagged as general in-sentence; shared JORC status and MRE/Scoping Study timing. No Orion mining-method, rate, schedule or cost material exists in the record, and nothing silica-specific exists at all - both recorded as absent. The host-rock question is routed to Occurrence rather than restated, and no comparison between the general host types and Orion's published host is drawn, because no impurity analysis exists to support one.

HPQ beneficiation is a purification problem, not a concentration one, and that single distinction organises the whole flowsheet. As a general matter of the industry the sequence runs: comminution sized to liberate mineral inclusions rather than to maximise recovery, and conducted so that the mill itself does not add iron; classification; magnetic separation and flotation to strip feldspar, mica and other mineral intergrowths; hot acid leaching to attack what remains on grain surfaces and in fractures; and finally high-temperature treatment, calcination or chlorination, to drive off volatiles and residual hydroxyl. Every step is measured by what is left behind, in parts per million. And there is a hard limit on all of it. Aluminium that has substituted for silicon inside the quartz lattice is part of the crystal, fixed when the quartz grew, and no crushing, leaching or roasting removes it. That is the reason an HPQ deposit has a ceiling set by its geology rather than by its plant, and the reason two rocks of identical quartz content can be worth entirely different amounts. It is also why the Properties section on this hub describes the product by its contaminant ceiling. No processing route, flowsheet, reagent regime or purification testwork for Orion quartz exists. Osmond has published no silica concentrate, no purity result and no statement that a route is under consideration, so nothing above describes anything intended for Orion material; it describes what the industry does to rock that has already qualified.

General industry characterisation of HPQ purification - liberation-oriented comminution, magnetic separation and flotation, hot acid leaching, high-temperature calcination or chlorination - and of lattice-substituted aluminium as irremovable, flagged as general in-sentence and consistent with the contaminant-ceiling framing already carried by Properties. No Orion silica flowsheet, testwork or concentrate result appears in the record - recorded as absent, and explicitly not presented as a route under consideration.

High-purity quartz goes where a trace of the wrong element ruins the batch. In general industry use its principal destinations are semiconductor crucibles - the vessels in which silicon ingots are pulled - photovoltaic manufacturing, and optical fibre. Each is an application where the material's job is to contact something purer than itself without contaminating it, which is why the specification is written as a contaminant ceiling. Silicon dioxide is also the material hafnium dioxide replaced in transistor gates below about 45 nanometres, so HPQ's own semiconductor role sits in the crucible around the process rather than in the device. This section describes what the product is used for in the world; nothing from Orion has been sold, qualified or contracted for any end use.

There is no world production figure for high-purity quartz in this hub, and the reason is worth more than a figure would be. As a general matter of the industry, HPQ is not enumerated as a commodity in the public statistical record. It is folded into industrial sand and silica categories that also contain glass sand, foundry sand and fracturing sand - materials measured in tens of millions of tonnes a year, against an HPQ market measured in tens of thousands - so any figure drawn from those categories is wrong by orders of magnitude for this product. Customs classifications do not separate it either. What circulates instead are private consultancy estimates built on plant capacities, which are neither public nor reconcilable against one another. The verified European and world reference table this publication uses for titanium, zircon, hafnium and the rare earths contains no silica or high-purity quartz line at all, so there is no audited figure here to quote and none is manufactured. Two things can be said without one. The market is small in tonnage and large in consequence, because the chains it feeds are worth a great deal more than the quartz is. And its concentration is a qualification effect rather than a geological one, which Supply Chain sets out. Orion adds nothing to any of this. Osmond has published no silica production, no resource and no tonnage of any kind, so the project does not appear in the supply picture even as a prospect.

General industry characterisation of HPQ as a product not separately enumerated in public production or trade statistics, flagged as general in-sentence; the EU/world reference table used by the other four hubs, which carries no silica or HPQ line, recorded here as the reason no figure is quoted; the absence of any published Orion silica data. No world production, producing-country, reserve or trade figure is given because none exists in the record - stated as absent rather than estimated.

An HPQ project is not finished when it has a resource. In general industry practice the milestone that decides one of these developments is a qualified product: a sample purified to specification, then a pilot run, then a customer trial, then acceptance into a buyer's supply base - a sequence that can take years, because a crucible or fibre maker who accepts an off-specification batch loses far more downstream than the quartz ever cost. Buyers therefore change supplier slowly and test exhaustively, and a project can hold a published resource for a long time without holding a business. That inverts the usual reading of project progress, and it is the single most useful thing to know when looking at any deposit in this family. It is also why the market can be moved by one new entrant: the volumes are small enough that a single qualified source matters. No HPQ project outside Orion is named or described in the material behind this hub. And Orion is not one. Osmond names Silica/HPQ as a strategic interest, and the record contains no silica target, no silica programme, no resource, no purification testwork and no qualification activity of any kind. There is a stated interest and there is nothing behind it yet; the hub records the interest as an interest, which is what it is, and does not convert it into a project.

General industry characterisation of qualification rather than resource definition as the decisive milestone in an HPQ development, flagged as general in-sentence; Osmond's own categorisation of Silica/HPQ as a strategic interest; the absence of any published Orion silica target, programme, resource or testwork. No HPQ project other than Orion is named because none appears in the material, and Orion is recorded as an interest rather than a project.

HPQ supply is concentrated, and the reason is qualification rather than scarcity. Quartz is abundant; quartz clean enough at the parts-per- million level, and able to stay clean through processing, is not. In general terms a source must meet both conditions, and very few deposits do - which is why the market is gated by deposit-specific chemistry rather than by tonnage. What would change that picture is a deposit demonstrated to qualify on impurity and published as such. No such demonstration exists for Orion, and this hub records the shape of the market rather than any position within it.

The policy position of this family has to be stated carefully, because the obvious shortcut is a basis error. Under the EU Critical Raw Materials Act (Regulation 2024/1252, adopted 11 April 2024, in force 23 May 2024), silicon metal is a listed strategic raw material, and the Act's 2030 benchmarks - at least 10% extraction, 40% processing and 25% recycling of annual EU consumption, no more than 65% of any strategic raw material from a single third country, and 27-month permitting for Strategic Projects - attach to the Annex I list. Silicon metal is not high-purity quartz. As a general matter of the industry they are different products at different stages of different chains: silicon metal is smelted from ordinary quartz or quartzite with carbon, while HPQ is a purified mineral sold for its contaminant ceiling and used, in its principal applications, as a container around a process rather than as a feedstock consumed by one. A listing that attaches to the first does not reach the second, and carrying it across would be exactly the substance-and-stage error this publication exists to prevent. Whether quartz, silica or high-purity quartz appears on Annex II, the 34 critical raw materials, is not established in the material behind this hub, and this section is written to that limit. What can be said is that HPQ's policy relevance is derivative: it sits upstream of semiconductor and photovoltaic manufacturing, and the instruments that address those sit at the manufacturing end. None of this describes a position held by Osmond. No silica data exists for Orion, so the project has no relationship to any of these listings.

Annex II coverage of quartz or silica is not stated in the material and is recorded as unestablished, not assumed either way. The absence of any published Orion silica data is stated as the record.

The environmental weight of high-purity quartz sits almost entirely in the purification, not in the hole in the ground. As a general matter of the industry, the mining is small and the refining is intense: hot acid leaching consumes aggressive reagents and generates acidic effluent, and the high-temperature calcination or chlorination that finishes the product is energy-hungry per tonne in a way no bulk mineral operation is. The footprint per tonne of product is therefore high while the total footprint stays small, and the two statements are easy to confuse in opposite directions. A second issue runs through every stage where quartz is crushed or milled: respirable crystalline silica is a recognised occupational hazard, and dust control is a permanent engineering feature of these operations rather than a compliance afterthought. Beyond the plant gate, most of the sustainability discussion attached to this material is really about what it enables, since its principal destinations sit inside the electronics and photovoltaic chains. None of this has any application to Orion. No silica processing route has been proposed, so none of the reagent, energy or effluent questions above has arisen; no environmental, permitting, energy or water material specific to silica has been published; and the project-level environmental record, which is itself thin, is carried on the hubs for the minerals Osmond has actually assayed rather than repeated here. There is no silica operation, proposed or described, to have an environmental profile.

General industry characterisation of HPQ purification as reagent- and energy-intensive per tonne, of the small absolute scale of the industry, and of respirable crystalline silica as an occupational hazard in quartz crushing and milling, all flagged as general in-sentence. No Orion silica processing route, and no silica-specific environmental, permitting, energy or water material, exists in the record - recorded as absent. The project-level environmental record is routed to the hubs that carry assayed minerals rather than duplicated on a family with no data.

The corporate chain behind high-purity quartz is short, and it is held together by contracts rather than by a market. In general industry terms a small number of producers supply refined quartz; the next link is the fabricators who melt it into crucibles, tubing and optics, some of whom are integrated backwards into quartz supply precisely because the input is hard to replace; and beyond them sit the wafer, cell and optical-fibre makers who never handle the mineral at all. Because qualification is slow and a failed batch is expensive far downstream, volumes move under long-term supply agreements rather than on any spot market, and there is no exchange price for the product. That structure - few sellers, few buyers, long relationships, no public price - is the reason the commercial layer of this family is so much harder to see than its geology. No company is named here, because none is named in the material behind this hub: no HPQ producer, fabricator, peer explorer or customer appears in it, and this section is not filled by inference from the structure above. The only company in the record is Osmond Resources itself - ASX: OSM, also quoted in Frankfurt as 4OG - which has published no silica data, holds no silica product and has announced no offtake, customer or partner for silica. The third parties that appear elsewhere in the record are engaged on the minerals Osmond has assayed, and none of them on quartz.

Applications sets out where high-purity quartz goes; this section covers the technologies that turn it into those things, and one that competes with it. In general industry use refined quartz is melted rather than reacted: fused into crucibles for the Czochralski pulling of silicon ingots, drawn into tubing and lamp envelopes, and worked into optics that have to stay transparent under ultraviolet light. Each of those depends on the same property - a melt that carries almost nothing but silicon and oxygen - and each fails in the same way when it does not. The competing technology is the interesting part. Silica of extreme purity can also be made rather than mined, by burning or hydrolysing silicon tetrachloride to deposit synthetic fused silica, and that route is how optical-fibre preforms are made and how the most demanding optical components are produced. Synthetic silica is purer than any natural quartz and far more expensive, so the two are not simple substitutes: some crucible designs line the melt-contact surface with synthetic material while the body stays natural quartz, which is a compromise between the cost of one and the cleanliness of the other. The practical effect is a ceiling on how far up the purity scale a mined product can sell. Nothing here connects to Orion. No Orion quartz has been purified, melted, tested or specified for any of these routes, and no technology has been named in connection with it.
