newest largest provincial park in Ontario.
South of algonquin provincial park has a vast of areas of exposed bedrock between palaeozoic limestone bedrock and precambrian granite bedrock, situated along the southern edge of the Canadian Shield is an area mostly composed of igneous rock which relates to its long volcanic history, the KHSS is a relatively undeveloped area which encompasses 37,587 hectares and features a rugged rolling landscape and small lakes, wetlands, forests and rocky barrens.
The Bedrock geology representation of the Kawartha Highlands is considered to be provincially significant, the park lies within the Grenville Province, one of the major subdivisions of the Canadian Precambrian Shield and more specifically within the central metasedimentary belt which is an accumulation of volcanic rocks, metasedimentary rocks and marbles type stone.
The surficial geology of the area is considered locally significant and is described as bare rock ridges and shallow till with over 60% of the region consisting of bare bedrock.
The soils of the Kawartha Highlands area are composed primarily of materials left behind by glaciers, ice-scoured bare rocklands are predominant in much of the area.
The Kawartha Highlands have rock outcrops with pockets of shallow sandy till or organic deposits but is primarily exposed bare bedrock.
There is total of 20 abandoned mine and quarry sites that have been inventoried but this may not include remnants of poorly documented 19th century mining activities.

The Grenville Province exposes the deep crustal root of a Himalayan-type collisional orogen. However, most of its components predate collisional orogeny, and the main episodes of crustal build-up are Andean in type.
Many of the ensuing volcano-plutonic arc belts are now parts of the gneiss complexes that typify large segments of the Grenville Province.
Ages of inferred magmatic arcs, intra-arc rifts, aborted back-arcs and island-arcs components range from Archean to Mesoproterozoic, most being Labradorian (1.71-1.60 Ga), Pinwarian (1.52-1.46 Ga), or Elzevirian (ca. 1.35-1.19 Ga).
Sedimentary basins and intrusive suites, including those with anorthosite massifs, host base metal (Zn), Fe- and hemo-ilmenite (Fe-Ti), and Fe oxide Cu-Au-REE-U deposits, and could collectively host Carlin, sedimentary exhalative, magmatic Ni-Cu-Co sulphides, PGE, Fe-Ti-V-P, and rare metal deposits.
Recognized volcano-plutonic belts host some volcanogenic massive sulphide deposits or share hallmarks of volcanogenic massive sulphide, Fe oxide Cu-Au-REE-U, epithermal Au, and porphyry Cu deposits.
The main aim of this synthesis is to inform and, through that information, disparage the wasteland paradigm that has afflicted the Grenville Province for so long.
Compared to the Superior Province, the Grenville Province is under-explored, under-prospected, and under-mapped but as it is, to a large extent, a reworked equivalent of the Andes, there is no reason why it should not be as prospective.
Like the known deposits, undiscovered deposits are likely to be metamorphosed and perhaps to have undergone ore mineral beneficiation providing a means to further increase the attractiveness of the Grenville Province.

|The Mineral Capital of Canada, 52 km. NE of Long Lake, Apsley Ontario|
is the "Mineral Capital of Canada" because of the variety and
quality of mineral species that occur, to date nearly 1,600 mineral species
have been identified in a region known as the Canadian Shield, consisting
of deformed carbonate metasedimentary rocks, a minor amount of volcanic
rock and a distinctive suite of nepheline syenites, syenites, skarn pyroxenites,
calcite veins and uranium-bearing nepheline rocks.
A list of minerals that have been mined industrially in the Bancroft area include corundum, feldspar, uranium, graphite, iron, marble, granite, lead, gold, molybdenite, apatite, beryl, fluorite, talc and sodalite.
Mining in most cases was carried out on a limited scale, mostly between 1880 and 1935 and was largely confined to open cuts and quarries.
The rock beneath Bancroft is between 1.0 and 1.2 billion years old and has been subjected to volcanic activity, glacial scouting, extreme heat and pressure, and intense faulting and folding.

|Mineral Types and Descriptions|
- a transparent purple variety of quartz, it can be found in six-sided
crystals or in massive chunks, this is Ontario-s mineral emblem.
Amazonite - this bright bluish-green mineral, a type of feldspar, breaks in straight sides, It has a grid-like attern of white streaks.
Apatite - this mineral usually occurs as six-sided, brittle crystals, It varies in colour from green and red to brown, blue and yellow.
Calcite - this common mineral comes in a variety of different colours, from colourless to white, ink, yellow, brown , blue, greenish, grey or a transparent black, When it breaks it is hexagonal in shape with straight sides which makes it fairly easy to identify, In its clear, colourless form, it is known as Iceland Spar.
Feldspar - it is one of the earth-s most abundant minerals - white, grey, blackish grey, pink in colour, it breaks in straight sided pieces at right angles to each other.
Fluorite - it can range from colourless to green, purple, blue, bluish-black, rose or yellow and is transparent to translucent, It has a glassy luster to it and is found in a cubic shape.
Garnet - small, translucent to transparent 12-sided crystals, Unlike the red gemstone, natural garnets found in the Bancroft area are usually brownish in colour but can be yellow, greenish-brown to black.
Hematite - a soft, dark reddish-brown colour, this mineral is mined for its iron ore content.
Mica - black or brown mica crystals can be found in a variety of rocks, It can occur as tiny flakes or in layered masses, The layers split into very thin, transparent sheets.
Pyrite - it looks like little chunks of glistening gold and is often called ( fools gold ), Generally you-ll find pyrite in small cubes or as a massive chunk.
Rose Quartz - it looks like massive chunks of pink glass, The pink is caused by small amounts of titanium in quartz.
Smoky Quartz - this is quartz which has been exposed to near-by radioactive minerals, It is usually found in large chunks but can be in six-sided crystal shapes.
Sodalite - this dark blue mineral is most often found in grey nepheline and is why the Princess Sodalite Mine came into existence, The blue colour is flecked or lined with white or light brown.
Tourmaline - this black, six-sided (hexagonal) crystal is often found in the pegmatite rock of the Bancroft area, It can also be white, blue, green, pink, red or brown in colour.
White or Clear Quartz - it comes in large glassy chunks but look for the six-sided crystals with the sides coming to a point at the end of the crystal.
