is DM on-line?
Data Metallogenica on-line is a continuously expanding searchable
database for global mineral deposits with over 40,000 image and text
quality digital images of 3,400 plate-mounted
sets of mini-specimens (approximately 70,000 samples), from over
3,000 mineral deposits in 70
countries and 6,000 photographs of individual samples from important
than 5,500 interpreted
mineral reflectance (PIMA) spectra of epithermal and porphyry
deposits, together with selected other deposit styles.
and image galleries,
district overviews, and exploration
case histories: constantly being expanded. University theses are also being included.
powerful and extremely fast text-based
search and select capability, allowing searching by deposit
name, geological province, country, state, region, commodity, deposit
type etc. Directed searches can be very specific, for example, search
for: copper & gold & not molybdenum in British Columbia

Tell me about DM and its data
Data Metallogenica is a unique mineral deposit information system.
Data Metallogenica is self-funding, owned and operated by AMIRA International
on behalf of the global minerals industry and associated institutions.
AMIRA International is the mineral industry's own research association
which is governed by an elected council.
The nucleus of DM is the world's most comprehensive and representative
sample collection of ores, alteration, host rocks and regolith from more
than 3000 deposits in 70 countries (now over 70,000 samples, an increase
of 40% since its acquisition by AMIRA). This original collection was developed
privately by Professor Peter Laznicka over a period of 30 years. Nearing
retirement from his position as Professor of Mineral Deposits at the University
of Manitoba in Winnipeg, Canada, he approached AMIRA International for
assistance in securing its survival in the public domain (click here
for an early history of DM).
AMIRA International, together with the former Australian Mineral Foundation,
and the South Australian Government (PIRSA) assisted in making this
a reality. In December 1999 the Data Metallogenica Centre housing the original collection was officially
opened in Adelaide by the Hon. Rob Kerin, Deputy Premier and Minister
for Primary Industries, Natural Resources and Regional Development,
Data Metallogenica Centre in Adelaide
and Sarka Laznicka
Hon. Rob Kerin at the opening of the DM Centre, flanked by Dr
Max Richards (Chairman, AMIRA) and Mr Alister McLeod (Chairman,
his geologist wife Sarka and their family moved to Australia with the
collection and continued to assist the Centre extend the collection.
AMIRA projects P554 and P554A allowed the expansion of the collection as well as making it available around the world through the World Wide
The scope of DM is continuously being broadened through addition of
supporting technical information such as deposit descriptions, maps
& sections, field and mine photographs, petrographic photographs
and spectral mineralogy. Information on mining, mineral processing,
environmental and other mining-related aspects will be added progressively
in the future.
Funding in its foundation stages has been made possible through the generous
support of over 100 large and small mining and exploration companies, government
institutions, and learned & professional societies around the world,
managed through two AMIRA collaborative projects:
P554 (1999-2002) - the acquisition and transport of the collection
in May 1999, the establishment of the Data Metallogenica Centre, the
collection of further material from Australia, South America and Africa,
the digital photographing and PIMA spectral measurement of the collection,
the development of the DM website, and its launch for sponsors in
AMIRA P554A (2002-2004) - the
continued collection and photography of further material from Australia,
Europe and elsewhere and the major addition of supporting data. Public
access to the website was launched at the Prospectors & Developers
Association of Canada (PDAC) Convention in Toronto in March 2003. Sponsorship
funds were augmented in this transition phase through public web subscriptions.
Metallogenica is required to be financially self-sufficient such that
subscription and sponsorship revenues must cover running costs. As a not-for-profit
minerals industry research association which receives no government grant,
AMIRA International needs the support of industry and teaching institutions
worldwide for it to continue fulfilling the vision of providing unique
information to future generations of explorers and educators.

is the Data Metallogenica Centre?
The Data Metallogenica Centre in Adelaide, South Australia houses approximately
70,000 rock samples, 1,500 thin and polished sections, a large literature
collection, 30-years' worth of field photography, 140 shelf-metres of
library, a map collection, and an archive of newly created digital rock
sample images. It has a 'viewing room' with excellent natural light,
microscopes, and facilities for making presentations to small groups.
Sample-sets are drawn from nearly 4,000 mineral deposits of all types
in 70 countries on all inhabited continents. Most were collected personally
by Peter Laznicka. His philosophy of seeking truly representative samples
of ores, alteration, host rocks and regolith from each deposit, provides
important consistency and a unifying strength to the sample base that
is rarely found at this scale of development. The major mines of the
world, understandably, are well covered, but unusually this extends
to minor occurrences and thereby provides important breadth to what
might be seen in any given mineral district.
Data Metallogenica contains not just one sample collection but two,
and each is designed to address a different information need:
- The Lithotheque Collection of
mini-samples is the most extensive. It houses 90% of all samples which
are arranged in sets of 20, permanently bonded to aluminium sheets
that fit into slotted shelves. Most Lithotheque sets come from a single
mine or mineral occurrence but are well supported by a useful number
of district lithology sets. Digital
imaging of the entire Lithotheque collection was carried out to
commercial standards using an in-house photo-studio and the highest
resolution digital scientific camera then available. Colour calibration
and manual proofing were employed in the quality control process.
Images are of extremely high resolution and use advanced data compression
for the web. In addition, each 18 Mb photographic source file is parent
to six smaller ones of different type and quality, designed to meet
a range of identified needs. Click on the link above for more information
on digital imaging.
- The Macrotheque Collection contains
approximately 8,000 hand-specimens ordered in 365 sets by geological
setting. Only selected of these sets have so far been captured as
NOTE: Following termination of it's lease, the DM Centre was temporarily closed in December 2005 with the physical collection in storage pending finding a new home. Website access has not been affected.

Can I contribute my own data?
international minerals community has funded Data Metallogenica so that
it may continue to develop as a major reference, training and educational
resource available to all. A significant core of data is already in
place and accessible on the web because of 30 years effort by the Laznicka
family and two major AMIRA projects. Long term growth and success requires
the engagement of companies, institutions and individuals by using the
resource and continuing to contribute non-sensitive data on their own
DM already is, and has the capacity to further develop, as a critical
repository of past and current data on mineral deposits not easily available
from other sources or which will be lost as mines progressively close
and a uniquely experienced generation leaves the industry.
