# Milieu Minerals publication QA

18 September 2026

This update repairs the existing publication and provides dedicated evidence, site and architectural experiences for all three projects.

| Project | Evidence | Sites | Architecture |
|---|---|---|---|
| Silver Peak, Nevada | [/evidence/silver-peak](/evidence/silver-peak) | [/explore/silver-peak](/explore/silver-peak) | [/gallery/silver-peak](/gallery/silver-peak) |
| Petersburg, Indiana | [/evidence/petersburg](/evidence/petersburg) | [/explore/petersburg](/explore/petersburg) | [/gallery/petersburg](/gallery/petersburg) |
| Kingsbury, Indiana | [/evidence/kingsbury](/evidence/kingsbury) | [/explore/kingsbury](/explore/kingsbury) | [/gallery/kingsbury](/gallery/kingsbury) |

## Completed checks

The reproducible audit checks local page and asset destinations, JavaScript imports and syntax, image decoding, structured-data parsing, archive CRCs, PDF signatures and the GLB container. It verifies architectural image hashes and camera IDs and compares all three master GeoJSON files with the preceding published source. Exact counts and results are in [QA_Results.json](/quality/QA_Results.json); individual destinations are in [Link_Audit.csv](/quality/Link_Audit.csv).

Original source images and native analytical rasters remain unchanged. The Silver Peak thermal and SWIR display PNGs use per-cell color lookup at the source grid dimensions. The source GeoTIFFs and display transformations are documented in [Spectral_Display_Register.json](/experience/silver-peak/Spectral_Display_Register.json).

The approved website images, logo, existing financial workbooks and site geometry were preserved. No new cost, building quantity, deposit grade or mineral-resource estimate was introduced. Downloaded plans and workbooks remain the commercial and engineering reference documents.

## Runtime and visual checks still outstanding

No browser interaction or screenshot pass was performed for this release. This existing buildless static publication has no compatible managed-preview server in the available environment. Local source checks do not establish that every interaction works in every browser.

ArcGIS, live Esri basemaps, the optional NBMG service and the model-viewer runtime are external dependencies. Requests from the available research tool could not verify those runtime endpoints. This is not evidence that the services are down. The publication includes locally hosted data and Leaflet fallback, plus direct evidence-atlas and original-image links. External source citations are retained and listed as not runtime verified in the audit.

The next browser acceptance pass should exercise all nine direct routes on desktop and mobile; lens, layer, opacity, swipe, phase and basemap controls; shared URLs and reloads; source dialogs; gallery zoom and camera links; original downloads; and the Kingsbury GLB. WebGL availability and device memory can affect 3D.

## Presentation and evidence boundaries

- Silver Peak and Petersburg's 3D terrain modes show planning massing from source footprints and recorded building heights. They are not exports of their complete Blender scenes, and regional terrain draping is not a finished-floor engineering model. Original registered renderings provide the architectural views.
- Kingsbury's downloadable GLB is the recovered shared scene. Original camera presets and metadata are supplied. Its interpretation and status remain those of the source proposal.
- Original registered renderings retain their original finish palette and source labels. Approved gold-tinted website presentations are identified separately. No generative rerender was performed during this repair.
- Radiometric eU, chemical assays, approximate historical summaries, uranium-in-air records and proposed monitoring remain distinct. No station coordinates were invented for the regional air records.
- ArcGIS receives native projected raster extents. The lightweight fallback's geographic raster envelope is a visual approximation; it is not suitable for survey measurements. Use native GIS and A3 drawings for precise geometry.
- Missing original elevation-profile series are explicitly represented as unavailable; no profile elevations were fabricated. Existing contour and terrain evidence remain accessible.
- No new hyperspectral acquisition, drilling result, assay campaign or regulatory approval is implied by the presentation update.
