Loma Dorada
Drone mapping and site photography for presenting Loma Dorada and maintaining its exploration records.
Project Map
Joel’s original map shows the project concessions. The next map shows the five proposed survey sectors, so the team can compare the concession outlines with the areas to be photographed.
Comparison · FlightHub acquisition coverage
Proposed survey coverage
The survey covers Azules I Central, East and West, Goyo and Carmina. The basemap will locate visible infrastructure and selected exploration features, with photographs attached to each site record.
The five survey sectors cover 1,088.6 ha. Parts of the concessions remain outside this campaign. Joel and his team will coordinate community agreement before overhead flights.
Current scope: RGB basemap using the Matrice 4 Enterprise. The survey will record current site conditions. LiDAR is not included at this stage.

Environmental-study reference polygon
The orange dashed outline shows the project polygon in 25SI2021MD030.pdf, page 16, Cuadro 1, for “Loma Dorada Segunda Etapa.” Select MIA footprint · Segunda Etapa under Go to location to inspect it against the Goyo survey area.
Coordinates were interpreted as WGS84 / UTM zone 13N, inferred from the site location. The coordinate polygon measures approximately 5.76 ha; the document separately describes 1.793 ha for the plant and tailings works. This layer shows the overall coordinate polygon, not individual facility footprints or a concession boundary. Joel’s team should confirm its relationship to the current project and which facilities exist. It does not establish current environmental authorization or permission to fly.
Location and access from Joel’s presentation
Loma Dorada is in Ejido El Tablón Número Uno (Las Cruces Cuatas), Rosario municipality. The presentation places it approximately 48 km southeast of Mazatlán and 240 km southeast of Culiacán. It describes access by Federal Highway 15, via the Mazatlán toll bypass or the free 15 Sur route, followed by local dirt roads. Villa Unión is identified as a nearby service town.
Markers identify locality reference points, not site entrances. Distances and access descriptions are from COSMIN PRESENTACION.pdf, page 3; confirm current road conditions and the final site entrance with Joel. Flight paths show the supplied plans, not community clearance.

Deliverables
Deliverables and site records
Survey outputs
RGB orthomosaic, digital surface model where reconstruction is valid, indexed aerial photographs, portable GIS files and a survey quality report.
Initial scope: up to 20 geolocated records supplied by the client or documented by 33Visual within the agreed field scope, a small edited aerial stills selection, one review round and one handover session.
Project records and access
Organize observations with an ID, coordinates, date, author, category and source. Keep dated campaigns identifiable, with private exploration data separated from approved presentation material.
The $10,000 USD annual technology fee provides a centralized project environment to organize, review and compare visual records over time, with unlimited users and access control. Future field campaigns are additional.
Exploration features and drill-site documentation
33Visual can document selected drill sites with geolocated photographs and a record of their visible surface condition, linked to the basemap.
Drill-site records and field scope
If exploration drill sites are present, Joel’s technical team will identify the locations to document. The 33Visual team can photograph each selected site and record the visible condition of the drill-hole collar, casing or cap, identification marker, drill pad and access. Dated ground and aerial photographs can also show erosion, drainage and evidence of rehabilitation. Each record will be linked to the basemap by hole ID or site ID, providing a reference for follow-up visits. This is a surface-condition record; downhole condition and rehabilitation compliance are outside the scope. Confirm the selected sites and ground access before fieldwork.
No LiDAR or bare-earth terrain product beneath vegetation is included in this phase.

Service rates include 33Visual’s fees; travel and contingency are allowances. The commercial fee is included in the campaign subtotal.
All amounts are USD, before applicable taxes. The annual technology fee is included once in the first-year investment. Subsequent field campaigns are priced separately. Additional fieldwork, if required, is budgeted at $1,500 per day.
Included assumptions
Routine on-site GNSS control/checks and daily image review. Travel is an allowance. Additional survey crews, extensive control, exceptional access costs, standby or expanded deliverables require a revised scope.
Outside this phase
LiDAR, certified cadastral work, underground mapping, full-site oblique 3D capture, geological/resource certification, a finished promotional film and future field campaigns.
Proposed investment for the agreed scope. Additional sites, field days or deliverables require a revised scope.
Community coordination
Community coordination
Joel and his team must secure agreement before flights over communities and explain that the work is for project mapping. Areas without agreement remain excluded from overhead flights.
Responsibilities before fieldwork
Joel and his team
Inform affected communities and their representatives about the project, who is conducting the flights, the planned areas and dates, and how the imagery will be used. Explain clearly that the drone is creating a project basemap and visual record, not conducting surveillance.
Secure community agreement before overhead flights. Provide 33Visual with the agreed areas, dates, restrictions and a named local liaison for questions or changes.
33Visual’s flight planning
Review mapping lines, launch and landing points, transit and return paths against the agreed areas. Areas without community agreement remain excluded from overhead flights; revise routes as needed.
The five exported polygons define the proposed acquisition scope. They do not establish community consent or confirm that every flight segment avoids occupied areas.
Next steps
Information needed from Joel
Survey area and site access
Confirm the five-sector acquisition scope and the areas agreed with communities. Retain concession outlines as context; the FlightHub sectors define the current capture plan.
Obtain the site entrance, local liaison and surface-access arrangements. Specify infrastructure, access routes and occupied areas to include or exclude.
Technical records and presentation
Confirm the presentation date, accuracy requirements, public/private records and future update workflow. COSMIN should approve the technical narrative and resource figures before publication.

- Basemap
- The geographic reference on which site photographs, exploration locations and later survey layers are organized.
- Orthomosaic
- A mosaic of aerial photographs corrected for camera tilt and terrain distortion to form a map image. Terminology reference: USGS.
- Digital surface model (DSM)
- An elevation model of the visible surface, including vegetation and structures. It does not necessarily represent bare ground beneath vegetation.
- AGL
- Above ground level: the aircraft’s height relative to the local ground surface.
- RGB
- Red, green and blue: standard visible-light photography used for this survey.
