A.  MINFILE/www Coding Card Forms

 

The MINFILE/www Coding Card can be used to enter a new MINFILE occurrence or revise an existing occurrence.  Data Entry is done exclusively online via MINFILE/www and it's Coding Card.  BC Geological Survey staff (see contacts in Chapter VII) and pre-authorized users are permitted to make revisions to the corporate MINFILE database.  To obtain authorization to capture mineral occurrence data online please contact the BC Geological Survey.  You will be asked to provide an email address where you may be contacted in the event that the data submitted requires further clarification.  (Should your email address change over time please notify the MINFILE office).  They will also add you to the appropriate user tables and you will be provided with the secure address to the MINFILE/www Coding Card which is transparent to common users.

 

You can enter the entire card at once and submit it, or save a partially completed card.

New MINFILE/www coding cards (via a separate and secure site) are accessed by selecting Add New Occurrence on the task bar on the left.

 

MINFILE revisions are accessed by searching and displaying the MINFILE record and clicking Revise this Occurrence from the MINFILE search results.

 

Add New MINFILE Occurrence

This indicates that a new occurrence is being created and all the data will be entered under a newly assigned MINFILE number. The official MINFILE numbers are assigned by the MINFILE staff after the record has been submitted and approved.

To create a new MINFILE Occurrence:

1.  Select Add New Occurrence from task bar.
2.  The coding card form opens on the Identification and Location tab.

 

Revise MINFILE Occurrence

This indicates that the data filled in on the coding form replaces or should be added to the existing data for the MINFILE record. Any change to the data, from a minor change to a major rewrite, is considered to be a revision.

 

A MINFILE/www Coding card revision can only be accessed by searching the MINFILE database for the current record.

 

To revise an existing MINFILE occurrence record:

 

1.  Search MINFILE to locate the record you want to revise.

 

HINT: Remember that you must enter blanks in the correct spot when entering a MINFILE Number. For example, if you enter '082M001', you will get "no search results".  The MINFILE Number must be entered as '082M__001' or '082M(space)(space)001"
 (9 characters).


NOTE:  The British Columbia Geological Survey is the only client that can assign MINFILE numbers.  MINFILE numbers are assigned based on NTS map sheet number. The first 4 to 6 digits of a MINFILE number represent the NTS map sheet which contains the occurrence; the remaining 3 digits are part of a numerical list of occurrences on that map sheet. For example, the first occurrence for NTS Map Sheet 082M would have the number "082M__001". Similarly, the 100th occurrence for the same map sheet has the number "082M__100".

 

2.  From the MINFILE search results page click the MINFILE number to display the record summary.
3.  The record summary page will open.
4.  Click the Revise this Occurrence button.
5.  The MINFILE/www Coding Card revision form opens. The fields are already populated with all the current data.

 

Note: You are working on a copy of the MINFILE Occurrence database record. After the record has been submitted it must be approved by MINFILE staff and then the MINFILE Occurrence database will be updated with the changes.  There may be a lag time in between when occurrences are submitted and when they are approved.  During this time the record will not be available for editing purposes.

Coding Card Options

 

You can enter the entire card at once and submit it, or save a partially completed card.  To view your own work in progress see Coder Task List.  Note that you will not be able to see edits in progress from other coders.

 

Data fields can be mandatory or optional. If you submit a coding card before all the mandatory fields have been entered you will get an error message detailing the fields that are missing.

 

Save - saves the MINFILE/www Coding Card information.
Note:
After a card has been saved you can edit it at any time from the coders task list.

 

Submit: - submits the card to the Ministry for approval.  Clicking Submit will also save any information entered.
Note: Once the card has been submitted, a coder will no longer be able to edit the record.  The Coder must wait until the Ministry approves the edits and the record will then become available for viewing and/or further editing if required.

 

Delete: - deletes the information - no further action is required.  Delete will delete a new coding card or a coding card revision - it does not delete an active occurrence record in the MINFILE database.
Note:
You can not delete a coding card after you've submitted it.  If you want the record deleted you will have to contact a member of the MINFILE Team.

 

Entering a Coding Card From a Remote Site - Security Alerts

If you are logged into the system from a remote site you may get a Security Alert when you click Save.  Just ignore it and proceed.

 

Adding Multiple Selections Dynamic Multi-Select Grid

 

 

The dynamic multi-select grid allows you the to add more than one selection into a table.

For example: An occurrence may have multiple names and commodities.

1.  Make your selection from the drop down box(es) and/or text box(es).
2.  Click the Add button.
3.  The selection is added as a row in the table above.

 

You can follow this same process to add multiple selections to the table.

To delete a row from the table click the X button and the row will be removed from the table.

 

Note: When saving, items are saved in the order that they appear in the grid (i.e. their ranking).  To reorder items in the grid, the items can be deleted and re-entered or you can use the drag and drop function.

Description

Comments

*Mandatory Field

This is a mandatory field.

Type, or 'copy and paste' capsule geology comments into this field.

Comment text may be edited or deleted by selecting the text and using the delete key or using 'cut' or 'copy and paste'.

This is a mandatory, detailed deposit description incorporating all the data in the coded fields and including more specific information on the geological setting and the controls of economic mineralization.

As a general rule the following types of information should be included in every capsule geology:

 

  • Brief pertinent comments on location.  
  • Brief comments on work history.  
  • Host rock Group(s), Formation(s), age, lithology and structure (regional and local geology for important occurrences and only local geology for minor showings).  
  • All ore, gangue and alteration mineralogy.  
  • Comments on the genetic type and significant characteristics of the deposit.  
  • General ore controls.  
  • Wherever available, include average assay values, gross production figures, and/or inventory figures.  
  • Descriptions are to be in proper sentences, not in point form and no abbreviations please.
 
Bibliography

When you first open the Capsule Geology & Bibliography Tab you will see a Collapse Capsule Geology button at the top like this:

 

 

This button was created to allow users to temporarily minimize the capsule geology to focus on the bibliography if they are long in length.  Once the capsule geology has been collapsed you will see a button at the top like this for re-opening the capsule geology.  The bibliography will always remain open at the bottom of the screen.

 


In the MINFILE Bibliography for any occurrence there are codes used, rather than full words (for example, "EMPR BULL" or "GSC MAP"). Each code represents a different publication which provided information on the selected occurrence.  A listing of these codes and what each one means is contained in Appendix F to this manual. An '*' indicates a significant reference. 

At the very bottom of the screen, underneath the bibiography text box you will see a button like this:


This button is used by Ministry staff to open the following screen which allows for cross-referencing of MINFILE bibliographic entries with the Property File database.  If you are not trained to perform this task then please ignore this area.  This manual does not cover this component.  For further information on Property File please visit http://www.empr.gov.bc.ca/Mining/Geoscience/PropertyFile/Pages/default.aspx or to go to the Property File searches go to http://propertyfile.gov.bc.ca/.

*Mandatory Field

This is a mandatory field.

Type or copy and paste Bibliography text into this field.

Bibliographic text may be edited or deleted by selecting the text and using the delete key or using cut or copy and paste.

The MINFILE bibliography is intended to identify all significant references for a deposit. In general, references are to be quoted in summary format, identifying publication, year and page. References of particular value in identifying or describing a deposit should be marked with an asterisk (*).

Standard referencing techniques should be used for publications or references which are not included in the list of abbreviations below or which do not fit in a summary format. When listing the appropriate references, the coding geologist should attempt to list them in the same order as outlined in the listing of abbreviated codes.

Click here to view MINFILE Bibliographic Codes (Appendix F)

Example of a standard reference:

Price, R.A. (1962): Fernie Map-area, East Half, Alberta and British Columbia, Geological Survey of Canada, Paper 61-24.

The corresponding MINFILE abbreviated reference is:

"GSC P 61-24"

"Property File" alone is not identified as a reference. The specific document used should be identified as the reference source and should be listed under the heading of "EMPR PF" which indicates that this item is found within the Ministry's Property File. Each item in the list is separated by a semicolon.

For example:  

EMPR PF (Total Energold Ltd., Annual Report, 1989; Cassiar Mining Corp., maps and notes, 1987).

The following formats should be followed in coding references:

 

  • List references in the same order as the listing of abbreviated codes.  
  • All reference abbreviations must be in upper case letters.  
  • All older versions of Ministry names should appear as "EMPR".  
  • Two or more similar references should be joined, e.g., GSC MEM 217, p. 118 and GSC MEM 110 should be: GSC MEM 110; 217, p. 118.  
  • Order of references should be lowest number to highest or earliest date to present.  
  •  Lists of references are separated by a semicolon (;) except for EMPR Assessment Reports which are separated by commas.  
  • An asterisk (*) should identify important references and should be placed before the number, year or name not at the beginning, e.g., EMPR ASS RPT 10172, *12470, 13131 and, EMPR AR *1901-13; 1914-98; *1936-45 GSC P 31; *45, p. 10.  
  • Property File references contain information in brackets. e.g., EMPR PF (Smith, B.J. (1939)......).  
  • Page numbers should follow the main reference separated by a comma e.g., EMPR OF 1987, p. 35 and GSC BULL, pp. 35-107.
  • The following exceptions use hyphens rather than page designations due to the volume of references, e.g., EMPR EXPL 1977-33, EMPR GEM 1981-252, and EMPR AR 1900-122; 1901-383.  

J. Coding Messages Tab

 

This text field allows the Ministry users to enter anecdotal information, sometimes confidential, regarding occurrences and anomalies.  The coding message tab is not part of the MINFILE/www Coding Card. This tab is used to communicate between coders, administrators and approvers. These messages are not included in the MINFILE record. Coders and administrators have the ability to view coding messages and add new messages to the card.

K. Printing a Report from the Coding Card

 

You don't need to exit the Coding Card to get a print-out. Refer to the section on Printing Reports for more information.

 

The report also serves as a hard copy back-up.

Note:  Printing a report while in the Coding Card is designed to always print to your default printer.  However, before it is printed, the report will be shown in the Print Preview mode for viewing.

 

L. Obtaining Help from the Coding Card

There is no need to exit the Coding Card to get help.  Simply click on the  HelpHelpbutton as shown on the screen print below (on the top right-hand corner of your screen) and the on-line help will open up in a new window using your browser.  The Help screens also link to the Appendices and the MINFILE/www Coding Manual.

 

 

M. Coder Task List

 

This screen allows coders to view their own work in progress if you have previously saved a partially completed MINFILE/www Coding Card or saved and submitted a new occurrence.  All items in the list are hyperlinked to the corresponding coding card for further editing and submission.

 

Note:  If you cannot see your work on the task list it may have been approved by Ministry personnel or may still be in the queue awaiting approval.  Check under search to see if it is in the corporate database.  You can always edit it again if it still requires modifications.

 

Security

You must be logged in with a valid BCeID to access or enter data into a MINFILE/www Coding Card.  Please contact the MINFILE Team for access to the MINFILE/www Coding Card.

 

Note: If logged into the system from a remote location you may get a Security Alert when you save a record.
