The short version

Mark Sumner is listed as an executive officer and director on 3 SEC Form D filings by 1 issuer between Apr 2020 and Oct 2026: Daura Gold Corp. (Vancouver, British Columbia, Canada (as filed: A1) — industry reported as "Other" — 2020–2026; $331K reported sold to 24 investors).

What this means One deal on file with the SEC. A Form D is the notice a company files after it starts selling a private investment — it is a notice, not an approval.

Listed alongside Christina Cepeliauskas (3 shared filings), Duncan Quinn-Smith (3 shared filings), William To Ping Tsang (3 shared filings), Raul Ernesto Lima Osorio (2 shared filings), Luis Francisco Saenz Rocha (1 shared filing) and 2 others.

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around Mark. Each name links to their own page.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — 1 court case matching the name, 11 bankruptcy cases matching the name listed in Key records below.

What this means 12 records came back. Each one is listed below with a link to the original document and a line saying why it matched. A name match is not proof it is the same person or company — read the why line and the document. Being sued or named in a release is an accusation, not a finding.

We compared 3 public filings for Mark Sumner and found 6 differences: Form D filed 16 days after the first sale; Form D filed 27 days after the first sale; and more below.

What this means These are differences between the sponsor's own SEC filings — both values, dates and sources are listed in Key records, section 4. Most have ordinary explanations; ask the sponsor.

4. Differences between public sources

Comparisons cover issuers and sponsor groups — see the issuer pages under Deals

6 differences found between the filings for Mark Sumner (compared 3 filings on Oct 24, 2026)

Note · Jan 20, 2025 – Feb 5, 2025

Form D filed 16 days after the first sale — Daura Gold Corp.

The filing says the first sale was Jan 20, 2025. The Form D was filed Feb 5, 2025 — 16 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 1 days past that.

What this means A late notice is common and carries no penalty by itself. It is worth asking the sponsor why the paperwork lagged.

Form D · Feb 5, 2025 ↗Daura Gold Corp. — PartnerFacts page ↗

Note · Mar 27, 2020 – Apr 23, 2020

Form D filed 27 days after the first sale — Daura Gold Corp.

The filing says the first sale was Mar 27, 2020. The Form D was filed Apr 23, 2020 — 27 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 12 days past that.

What this means A late notice is common and carries no penalty by itself. It is worth asking the sponsor why the paperwork lagged.

Note · Feb 5, 2025 – Oct 15, 2026

Mark Sumner's role changed at Daura Gold Corp.: director → executive officer, director

The Feb 5, 2025 filing lists Mark Sumner as director; the Oct 15, 2026 Form D lists executive officer, director.

What this means Roles on Form D are self-reported by the issuer. A change can mean a real change in who runs the company, or just a different box ticked. Ask who makes decisions today.

Note · Jan 20, 2025 – Feb 5, 2025

No amendment in the last 12 months on an offering that may still be open — Daura Gold Corp. (latest filing Feb 5, 2025)

The latest filing for this offering is dated Feb 5, 2025 (first sale Jan 20, 2025). It reports $257,699 sold of $575,361 offered. No later amendment is in our index as of Oct 24, 2026.

What this means SEC rules expect a yearly amendment while an offering is still going. The raise may simply have ended — a Form D does not say when it closed. Ask the sponsor whether the offering closed, when, and at what amount.

Note · Jun 12, 2026 – Jun 26, 2026

Same name, different state: "Mark Sumner" (NV) is a separate record

This page covers filings where the address state is A1. A separate record, "Mark Sumner" with address state NV, is listed on 2 filings — most recently by Geomorphic AI (Jun 26, 2026). Both records have filings in the same period (Jun 12, 2026 to Jun 26, 2026).

What this means Two records with one name were active at the same time. That can be one person listing different company addresses, or two different people. We keep them apart until a filing ties them together. Check both pages before you decide.

What is compared

What is compared: every Form D and D/A we hold for this subject, side by side — filing dates vs. first-sale dates (the 15-day rule), amendment timing on open offerings (the yearly-amendment expectation), amounts sold, investor counts, offering amounts and minimums across amendments, industry and size bands, addresses, how each person's name and role is written, paid sellers' CRD numbers, and (for groups) where the member companies were formed and sit. Everything is as filed by the issuer; the SEC does not check it. Differences are common and usually have ordinary explanations — we show both values, the dates, and the source so you can ask. As of Oct 24, 2026.
