General information
Metamorphic schists (phyllite, quartzitic and micaceous) are used in the building construction as the major component of a fine gravel cover of roll tar paper (phyllite and micaceous schists), in an agriculture as inert dust carrier of pesticides (phyllite and micaceous schists), and in the manufacture of fire-proof materials as one of the major components of a fire-proof cement (quartzitic schists).
Phyllite schists
Phyllite schists have been documented in 3 deposits in Opolskie Voivodeship (map): Chomiąża, Dewon-Pokrzywna and Dewon-Pokrzywna 2. The total anticipated economic resources of phyllite schists amounted to 15,415.41 thousand tonnes as of 31 December 2022. Similarly to the previous years, the exploitation in 2022 was carried out only from the Dewon-Pokrzywna deposit – it was equal 159.11 thousand tonnes and decreased by 24.39 thousand tonnes in comparison with 2021 (it means the drop was equal 13.29 %). The anticipated economic resources of this deposit decreased – due to the exploitation, losses and the better deposit exploration – by 309.06 thousand tonnes (2.35 %) and amounted to 12,842.37 thousand tonnes. Two other deposits of phyllite schists have not been exploited.
Figure below shows changes in domestic resources and production of phyllite schists in Poland in the years 1989-2022.
Quartzitic schists
Quartzitic schists occur within the Strzelin granite massif in Dolnośląskie Voivodeship. The only 1 documented and exploited deposit of this raw material in Poland is the Jegłowa deposit. Therefore, it should be particularly protected. Its anticipated resources (excluding protective pillars) in 2022 were equal 8,654.24 thousand tonnes and economic resources 2,723.28 thousand tonnes. The deposit was not exploited in 2022.
Figure below shows changes in domestic resources and production of quartzitic schists in Poland in the years 1989-2022.
In the latest edition of The balance of prospective mineral resources of Poland, there was the assessment of resources prospective for quartzite and quartzitic schists in Poland updated*. The main criteria adopted for establishing the quartzite and quartzitic schists deposits were: the deposit thickness (minimum of 5 m), the overburden thickness to the deposit thickness ratio (maximum 0.5), the SiO2 content (minimum of 95 %), the Fe2O3 + TiO2 + alkali content (maximum of 1 %). As the result of such attitude, the prospective resources of quartzitic schists were assessed to be equal 8.49 million tonnes within 1 area which is strictly connected to the already documented Jegłowa deposit (the so-called layers from Jegłowa). To the prospective resources there were also the deeper parts of the Jegłowa deposit included, together with the minor area of the schists outcrop west of the Jegłowa deposit.
Micaceous schists
Micaceous schists have been documented in 2 deposits located in Dolnośląskie Voivodeship: Jawornica deposit in Kłodzko County and Orłowice deposit in Lubań and Lwówek Śląski Counties (map). The total anticipated economic resources of the raw material as of 31 December 2022 were determined at 6,603.44 thousand tonnes and economic resources at 2,990.05 thousand tonnes. The resources of the Orłowice deposit account for 85.55 % of the total anticipated economic resources and 82.78 % of the total economic resources of the given raw material. The exploitation was carried out only from the Jawornica deposit (0.50 thousand tonnes). As a result of the output and exploitation losses, both the anticipated economic resources and economic resources of the raw material decreased in comparison with 2021 by 0.50 thousand tonnes each.

Quartzitic schists
Quartzitic schists occur within the Strzelin granite massif in Dolnośląskie Voivodeship. The only one documented and temporarily exploited deposit of that raw material in Poland is Jegłowa deposit. Therefore, it should be particularly protected. Its anticipated resources (beyond protective pillars) in 2019 were equal 8,681.39 thousand tonnes and economic resources 2,750.13 thousand tonnes. Both types of resources decreased by 11.27 thousand tonnes each, due to the exploitation and the resources reclassification.
Figure below shows changes in domestic resources and production of quartzitic schists in Poland in the years 1989-2019.
In the latest edition of The balance of prospective mineral resources of Poland, there was the assessment of resources prospective for quartzite and quartzitic schists in Poland updated*. The main criteria adopted for establishing the quartzite and quartzitic schists deposits were: the deposit thickness (minimum of 5 m), the overburden thickness to the deposit thickness ratio (maximum 0.5), the SiO2 content (minimum of 95 %), the Fe2O3 + TiO2 + alkali content (maximum of 1 %). As the result of such attitude, the prospective resources of quartzitic schists were assessed to be equal 8.49 million tonnes within 1 area which is strictly connected to the already documented Jegłowa deposit (the so-called layers from Jegłowa).

Micaceous schists
Micaceous schists occur within two deposits located in Dolnośląskie Voivodeship: Jawornica deposit in Kłodzko County and Orłowice deposit in Lubań and Lwówek Śląski Counties. The total anticipated economic resources of the mineral raw material as of 31 December 2019 were estimated at 6,648.01 thousand tonnes and economic resources at 3,034.60 thousand tonnes. The resources of Orłowice deposit account for 85.63 % of anticipated economic resources and 83.00 % of economic resources. The total anticipated economic resources of the raw material decreased in comparison with 2018 by 0.97 thousand tonnes due to the output from Jawornica deposit. In the case of the economic resources, they dropped by 1,352.63 thousand tonnes, mainly as a result of the exploitation (−0.97 thousand tonnes) and the approval of a new deposit development plan for Orłowice deposit (−1,351.66 thousand tonnes).

2018
Metamorphic schists (phyllite, quartzitic and micaceous) are used in the building construction as the major component of a fine gravel cover of roll tar paper (phyllite and micaceous schists), in an agriculture as inert dust carrier of pesticides (phyllite and micaceous schists), and in the manufacture of fire-proof materials as one of the major components of a fire-proof cement (quartzitic schists).
The occurrence of the schists deposits in Poland is presented on the map.
Three deposits of phyllite schists from Opolskie Voivodeship are the only deposits of that raw material hitherto documented in Poland: Chomiąża, Dewon-Pokrzywna and Dewon-Pokrzywna 2. Anticipated economic resources of phyllite schists in Poland were estimated as of the end of 2018 at 16,336.30 thousand tonnes. Similarly to the previous years, the exploitation was carried out only from Dewon-Pokrzywna deposit – it amounted to 159.99 thousand tonnes and decreased by 2.02 thousand tonnes (1.25 %) in comparison with 2017. The anticipated economic resources of this deposit decreased by 220.08 thousand tonnes (1.57 %) due to the exploitation and losses and amounted to 13,763.26 thousand tonnes. Two other deposits are not being exploited.

Metamorphic phyllite, quartzitic and micaceous schists are used in the building construction as the major component of fine gravel cover of roll tar paper (phyllite and mica schists), in agriculture as inert dust carrier of pesticides, and in the manufacture of fire-proof materials as one of the major components of fire-proof cement (crystalline schists).
The 3 deposits of phyllite schists from the Opole Voivodeship are the only deposits of that raw material hitherto documented in Poland (map): Chomiąża, Dewon-Pokrzywna and Dewon-Pokrzywna 2. Anticipated economic resources of phyllite schists in Poland were estimated in 2013 at about 17.66 million tonnes and production (from Dewon-Pokrzywna deposit) 143.40 thousand tonnes. Production decreased by 46.19 thousand tonnes (24.4 %) in comparison with 2012. The anticipated economic resources of this deposit decreased by 228.85 thousand tonnes and amounted to 15,082.77 thousand tonnes. Two other deposits are not being exploited. The Chomiąża deposit has been abandoned since 1989 and the remaining resources are estimated at 0.31 million tonnes.
Quartzitic schists occur only within the Strzelin granite massif at Jegłowa in the Lower Silesian region (Dolnośląskie Voivodeship). The Jegłowa deposit is still the only deposit of that raw material which has been documented in Poland. Its anticipated resources were estimated in 2013 at 8,697.03 thousand tonnes and economic resources at 2,765.76 thousand tonnes. The resources increased by 2,825.18 thousand tonnes due to the approval of a new deposit management plan with reclassified resources. Production of quartzitic schists in 2013 was equal 25.01 thousand tonnes (decreased by 3.17 thousand tonnes). The Jedłowa deposit is widely known for occurrences of beautiful quartz crystals, especially clear and colorless rock crystals.
Micaceous schists occur in Orłowice deposit located near Lwówek Śląski and in Jawornica deposit in Kłodzko County. Total anticipated economic resources of mineral raw material as of 31 December 2013 were estimated at 6,668.1 thousand tonnes, and economic resources at 4,406.35 thousand tonnes. The resources from Orłowice deposit account for 85.6 % of anticipated economic resources and 88.2 % of economic resources. In 2013, production from Orłowice deposit increased by 9 % to 2.51 thousand tonnes and from Jawornica deposit decreased by 60 % to 0.30 thousand tonnes (schists from this deposit are used as crushed stones).

The 3 deposits of phyllite schists schists from the Opole Voivodeship are the only deposits of that raw material hitherto proven in Poland (map): Chomiąża, Dewon-Pokrzywna and Dewon-Pokrzywna 2. Anticipated economic resources of phyllite schists in Poland were estimated in 2012 at about 17.88 million tonnes and production (from Dewon-Pokrzywna deposit) 189.59 thousand tonnes. Production increased by 32.59 thousand tonnes (21 %) in comparison with 2011. Two other deposits are not being exploited. The Chomiąża deposit has been abandoned since 1989 and the remaining resources are estimated at 0.31 million tonnes.
Quartzitic schists occur only within the Strzelin granite massif at Jegłowa in the Lower Silesian region (Dolnośląskie Voivodeship). The Jegłowa deposit is still the only deposit of that raw material which has been documented in Poland. Its anticipated resources were estimated in 2012 at about 5.90 million tonnes and economic resources at 2.76 thousand tonnes. Production of quartzitic schists in 2012 was equal 28.18 thousand tonnes (decreased by 12.21 thousand tonnes). The Jegłowa deposit is widely known for occurrences of beautiful quartz crystals, especially clear and colorless rock crystals.
Micaceous schists occur in the Orłowice deposit located near Lwówek Śląski and in the Jawornica deposit in the Kłodzko area. Total anticipated economic resources of that mineral raw material as of 31 December 2012 were estimated at 6.67 million tonnes, and economic resources at 4.41 million tonnes. In 2012, production of schists from the Orłowice deposit decreased to 2.30 thousand tonnes and from Jawornica deposit increased to 0.77 thousand tonnes (schists from this deposit are used as crushed stones).

Metamorphic phyllite, quartzitic and mica schists are used in the building construction as the major component of fine gravel cover of roll tar paper (phyllite and mica schists), in agriculture as inert dust carrier of pesticides, and in the manufacture of fire-proof materials as one of the major components of fire-proof cement (crystalline schists).
The two deposits of phyllite schists from the Opole Voivodeship are the only deposits of that raw material hitherto proven in Poland (map). Exploitation of the Chomiąża was phased out in 1989, leaving relatively small part of its economic resources (about 310 thousand tonnes). In 2001, production was recommenced at other deposit, the Dewon-Pokrzywna deposit at Jarnołtówek near Głuchołazy. In 2010 there was new deposit documented – Dewon-Pokrzywna 2. Anticipated economic resources of phyllite schists in Poland were estimated in 2011 at about 18.08 million tonnes and production (from Dewon-Pokrzywna deposit) 157 thousand tonnes. Production increased by 100 thousand tonnes in comparison with 2010.
Quartzitic schists occur only within the Strzelin granite massif at Jegłowa in the Lower Silesian region. The Jegłowa deposit is still the only deposit of that raw material which has been proven in Poland. Its anticipated resources were estimated in 2011 at about 5.93 million tonnes and economic resources at 3.78 thousand tonnes. Production of quartzitic schists in 2011 was equal 40 thousand tonnes (increased by 38 thousand tonnes). The Jedłowa deposit is widely known for occurrences of beautiful quartz crystals, especially clear and colorless rock crystals.
Micaceous schists occur in the Orłowice deposit located near Lwówek Śląski and in the Jawornica deposit in the Kłodzko area. Total anticipated economic resources of that mineral raw material as of 31 December 2011 were estimated at 6.67 million tonnes, and economic resources at 4.41 million tonnes. In 2011, production of these schists from Orłowice deposit increased to 4.79 thousand tonnes and from Jawornica deposit decreased to 0.52 thousand tonnes (schists from this deposit are used as crushed stones).
