Nova Scotia Department of Energy and Mines (NSDEM) has identified
approximately 8,400 shafts, adits, slopes, open cuts, trenches and associated
underground workings </span><span style='font-size: 11.5pt; font-family: Helvetica, sans-serif;'><a href='https://novascotia.ca/natr/meb/pdf/ic42.asp'><span style='font-size:10.0pt;font-family:"Arial",sans-serif;color:windowtext'>(Information
Circular ME 42)</span></a></span><span style='font-size: 10pt; font-family: Arial, sans-serif;'> which are, or were at one time, open to
the surface. These mine openings are spread over almost 700 mining areas;
however, the database is not, and should not be considered, a complete record
of abandoned mine openings in the Province. Additional abandoned mine openings
exist which have not been documented. As well, the database does not include
surface expressions of subsidence resulting from the collapse of underground
mine workings.</span><span style='font-size: 11.5pt; font-family: Helvetica, sans-serif;'></span></p>
<p style='margin: 6pt 0cm;'><span style='font-size: 10pt; font-family: Arial, sans-serif;'>The inventory does not include
quarries, sand pits, open pit mines, naturally occurring caverns or subsidence
features related to karst topography.</span><span style='font-size: 11.5pt; font-family: Helvetica, sans-serif;'></span></p>
<p style='margin: 6pt 0cm;'><span style='font-size: 10pt; font-family: Arial, sans-serif;'>NSDEM regularly updates the
database whenever sites are visited or whenever previously undocumented mine
openings are identified. In 2018 LIDAR coverage of the Eastern shore, portions
of the South shore and much of Industrial Cape Breton was released by the
Geographic Information Services Section of Service Nova Scotia and Internal
Services. Soon after, NSDEM undertook the initiative to evaluate the coverage
areas for both known and undocumented abandoned mine openings. It was found
that interpretation of LIDAR imagery could be used to locate historical mine
openings, not previously mapped, and to confirm or adjust the locations of
known AMO’s. As a result, more than 800 mine openings have been added to
the database and an additional 400 or so have had their location revised based
upon the available information.</span><span style='font-size: 11.5pt; font-family: Helvetica, sans-serif;'></span></p>
<p style='margin: 6pt 0cm;'><span style='font-size: 10pt; font-family: Arial, sans-serif;'>As well, the following points
should be noted:</span><span style='font-size: 11.5pt; font-family: Helvetica, sans-serif;'></span></p>
<ul>
<li><span style='font-size:10.0pt;font-family:"Arial",sans-serif'>The majority of
the abandoned mine openings on Crown Land have either been surveyed by GPS
or positioned utilizing LIDAR imagery</span><span style='font-size:11.5pt;
font-family:"Helvetica",sans-serif'></span></li>
<li><span style='font-size:10.0pt;font-family:"Arial",sans-serif'>The locations of
most of the identified abandoned mine openings on Private land have not
been surveyed and therefore their locations in the database are provided
at a lower level of confidence</span><span style='font-size:11.5pt;
font-family:"Helvetica",sans-serif'></span></li>
<li><span style='font-size:10.0pt;font-family:"Arial",sans-serif'>Not all mine
openings have been examined by a physical inspection of the opening during
a visit to the site</span><span style='font-size:11.5pt;font-family:"Helvetica",sans-serif'></span></li>
<li><span style='font-size:10.0pt;font-family:"Arial",sans-serif'>Since the
information was compiled, new openings may have developed due to the
deterioration of underlying abandoned mine workings</span><span style='font-size:11.5pt;font-family:"Helvetica",sans-serif'></span></li>
<li><span style='font-size:10.0pt;font-family:"Arial",sans-serif'>Conditions of
sites which have been examined may change since they were last assessed.

</ul>
<p style='margin: 6pt 0cm;'><span style='font-size: 10pt; font-family: Arial, sans-serif;'>Undocumented abandoned mine
openings resulting from small scale illegal mining, particularly related to
coal, are added to the inventory when reported to, or identified by NSDEM staff
during site visits. In some cases, a number of mine openings are located in
very small areas and are associated with subsidence features similar to mine
openings. In many of these cases, each individual mine opening may not be
uniquely identified in the inventory, and a group of mine openings are
represented by a single mine opening data point. Users of the database with an
interest in these areas are encouraged to contact NSDEM for more detailed
information.</span><span style='font-size: 11.5pt; font-family: Helvetica, sans-serif;'></span></p>
