Along with the Chalcopyrite there are also very sharp and lustrous Sphalerite crystals and the whole is bordered by lenticular crystals of Siderite. The upper levels of Panasqueira continue to provide surprising novelties, with specimens different from what was previously known.
Minas da Panasqueira, Aldeia de São Francisco de Assis, Covilhã, Castelo Branco, Cova da Beira, Centro  Portugal (06/2021)

Specimen size: 8.7 × 4.7 × 3.1 cm = 3.43” × 1.85” × 1.22”

Main crystal size: 4.8 × 3.1 cm = 1.89” × 1.22”

ND37AF2: Group of Chalcopyrite crystals that show the dominant forms of a ditetragonal scalenohedron. They are coated by small, very bright Arsenopyrite crystals, Muscovite aggregates, platy Siderite crystals that fully cover the back side and a doubly terminated Fluorapatite crystal. The upper levels of Panasqueira are currently offering surprising and pleasant novelties, with samples that are very different from what has been known from this mine.
Minas da Panasqueira, levels 0-1, Aldeia de São Francisco de Assis, Covilhã, Castelo Branco, Cova da Beira, Centro  Portugal (03/2017)

Specimen size: 9.8 × 7.8 × 4.7 cm = 3.86” × 3.07” × 1.85”

Main crystal size: 4.3 × 3 cm = 1.69” × 1.18”

MR27AM3: Group of large Chalcopyrite crystals with the typical curvatures seen in Panasqueira specimens, very aerial, lustrous, and on matrix. With sharp and lustrous Arsenopyrite crystals and small coatings of lenticular Siderite crystals. As a whole, it is a very high level piece both for its perfection and for the quality of the Chalcopyrite crystals, a species that in this mine does not usually yield very good specimens.
Minas da Panasqueira, Aldeia de São Francisco de Assis, Covilhã, Castelo Branco, Cova da Beira, Centro  Portugal

Specimen size: 13.1 × 10.4 × 7.1 cm = 5.16” × 4.09” × 2.80”

Main crystal size: 5 × 3.3 cm = 1.97” × 1.30”

NB12AA4: Aggregate of Sphalerite crystals with very well defined faces and edges, with a deep black color and very well marked growth striations. The aggregate has a superficial Pyrite patina and small leafy Muscovite growths on the back. Current mining works on the 0 level at Panasqueira are characterized by good samples of species relatively rare in other areas and levels.
Minas da Panasqueira, level 0, Aldeia de São Francisco de Assis, Covilhã, Castelo Branco, Cova da Beira, Centro  Portugal (07/2014)

Specimen size: 3 × 2.9 × 2.2 cm = 1.18” × 1.14” × 0.87”

EY28AK1: Parallel growths of complex Sphalerite crystals, very bright, with fine striated edges, white lenticular crystals of Siderite, spheroidal aggregates of laminar crystals of Muscovite and hyaline crystals of Quartz. Although Sphalerite is not a rare species in this mine it rarely occurs in such well-formed crystals. The specimen comes from a recent find in the upper levels of Panasqueira.
Minas da Panasqueira, levels 0-1, Aldeia de São Francisco de Assis, Covilhã, Castelo Branco, Cova da Beira, Centro  Portugal (06/2019)

Specimen size: 6.3 × 5.4 × 3.2 cm = 2.48” × 2.13” × 1.26”

Main crystal size: 3 × 2.8 cm = 1.18” × 1.10”

N13BF2: A real rarity for this mine, as we think that almost no one has ever noted the presence of Tetrahedrite at Panasqueira. The small brilliant crystals are gray-black and are on prismatic Siderite. There is also some green Fluorapatite, which adds to the interest of the specimen. We will give the buyer a copy of the analysis of the Tetrahedrite.

Specimen size: 8 × 6.5 × 3 cm = 3.15” × 2.56” × 1.18”
