At present, situation in the V.C.O. stone territory there are about 100 activities involved in quarrying and working on ornamental stone, distributed in 22 of the 38 townships of the territory and providing employment for 700 people, while allied industries are estimated to be for around 600 in number. Annual average turnover reaches approximately € 57,000,000 with capital investment in machinery and equipment of over € 77,000,000. They may be categorized as follows:
• quarrying companies, which quarry the blocks from the quarries and carry out perfunctory work at the quarry site itself;
• industrial companies, which produce semi-finished products, such as slabs from gangsaw blocks; by its very nature, this sector has large production volumes but a limited range of finishing types (flame process, bush hammering, and polishing); companies specializing in the production of manufactured goods of any type carried out by design;
• artisan companies, specializing in the production of smaller manufactured products obtained via splitting (riven) processes (opus incertum furnishings).

For all intents and purposes, the Val d'Ossola territory is rather advanced in terms of production technology; it is not by accident that its quarry basins have been the object of foreign studies for the sector, especially by Brazil, Canada and China, despite the fact that the basins are located at heights of approximately 1,000 metres and reaching as high as 1,400 metres, and thus also present, as does Val Formazza, some problems of a practical nature and of access in wintertime.
The distinguishing feature of the V.C.O. area stone industry lies in the variety of materials produced: for all types of rock quarried, there is the production of various types of blocks (from gangsaws or block-cutters), to the saw-cut stage (slabs cut, by diamond wire blade, or large-diameter blade), to the semi-finished products (slabs with bush hammered, flame process and polished surfaces), to finished products. The latter category finds numerous applications in the housing and industrial construction industry, for flooring and external and internal furnishings such as risers, treads, bases, thresholds, sills, window frames, portals, frames, surfaces, balconies, stone shelves and columns; or in urban design for cordons, street paving, benches, fountains, flower boxes; with interior design objects such as fireplaces, tables, kitchen and bathroom surfaces; in the funeral services industry (monuments and chapels). Another important use to remember is the current use made of Montorfano white granite to make grindstones for paper mills and presses.
