NOTES TO THE FINANCIAL STATEMENTS

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Business: Original Sixteen to One Mine, Inc. (the Company)
incorporated in 1911, actively operates the Sixteen to One mine in
Alleghany, California.

Inventory: Inventory consists of gold bullion, specimens and jewelry.
Gold bullion is quoted at the market price.  Jewelry and specimens are
quoted at the market price for gold content plus labor cost.
Inventory is accounted for using the average cost method. Inventory is
adjusted by gold at the spot price for the quarter.

Fixed Assets:  Fixed assets are stated at historical cost.
Depreciation is calculated using straight-line and accelerated methods
over the following useful lives: Vehicles 3 to 5 years, Equipment 5 to
7 years, Buildings 18 to 31.5 years. Company does not capitalize
underground expenses or exploration.

Depletion Policy:  Because of the geological formation in the
Alleghany Mining District, estimates of ore reserves cannot be
calculated, and accordingly, a cost per unit depletion factor cannot
be determined.  No depletion deduction is recorded.

Revenue Recognition:  Revenue is recognized using quoted market prices
for gold when mined. For income tax purposes revenues are not
recognized until the gold is sold.

Use of Estimates:  Preparation of financial statements in conformity
with generally accepted accounting principles requires management to
make estimates and assumptions.  Estimates and assumptions affect
reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of revenues and expenses
during the reporting period.  Actual results may differ from these
estimates.

 GENERAL NOTES

1.  In accordance with directive from the Securities and Exchange
Commission (SEC)and Industry Guide 7, reference for all intent and
purposes to the Company's employees as miners, its properties as mines
or its operation as mining does not diminish the fact that the Company
has no proven reserves for the period. The "exploration state" as
defined in Guide 7(a)(4)(iii) may apply.

2. Financial statements contain adjustments (consisting only of normal
recurring accruals) necessary to present fairly the Company's
financial position at March 31, 2021 and December 31, 2020. The
results of operations and cash flows for the first quarter of 2021 and
2020 and showing the three-month year-to-date ending March 31, 2021
and 2020. Unaudited financial statements are prepared in accordance
with Generally Accepted Accounting Principles for interim financial
information and with instructions to Form 10-Q and Item 310(b) of
Regulation S-B.

Item 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF PLAN OF OPERATION

The Sixteen to One mine in the Alleghany Mining District is a unique
gold deposit and requires an unfamiliar operation, which is recognized
by its owners, its miners, geologists, engineers, and some public
agencies for 125 years. It is a rare California high-grade, hard rock,
underground gold mine. The Company celebrated its 100th year
anniversary on Oct. 9, 2011. becoming the oldest gold mining
corporation in the United States. Experts estimate that sixty percent
or more of the gold deposit remains. Production is approximately
1,500,000 ounces of gold.


Over thirty miles of horizontal workings and millions of cubic feet of
vertical excavations called stopes exist.  The entire grounds are not
maintained for mining.  Once an area is targeted for mining, travel
ways and escape routes are brought into safety compliance.  Production
miners set up a heading (face) and begin a drill-blast-muck sequence
into the quartz.  Gold is hosted in the quartz vein as exceedingly
rich concentrations called "pockets". Metal detectors are regularly
used underground as a tool for guiding the direction of the work.
Metal detectors are also used as a tool to classify the ore
underground. A positive effect reduces the volume of rock taken from
the mine, thereby reducing costs.

In 1992, the company initiated a gold marketing plan of selling gold
in quartz as a gemstone.  This produces revenue significantly greater
than selling gold into the spot market.  Demand for the Sixteen to One
gold-in-quartz gemstone exceeds supply.

Production has been termed a "feast or famine" situation for over 100
years. Reserves in this high-grade gold mine cannot be termed as
"proven".  At the Sixteen to One the search for gold embraces: (1)
historical maps; (2) geophysical prospecting; (3) underground
headings, drifts or tunnels. When operations detect the presence of
gold, the Company evaluates the environment and changes from
exploration to development to production rapidly. The company hoards
gold and sells it according to short-term cash needs. These facts
create headaches for the Company managing cash flow between pockets.

 Balance Sheet notes:

Gold inventory is recorded at spot price despite proven additional
value for specimen and gem-stone material which is substantially
greater than spot price. Jewelry inventory is recorded at labor plus
gold cost.

No value is recorded on the balance sheet for timber reserves.  The
company owns 470 acres of prime forested timberland.  No value is
recorded on the balance sheet for the Company owned water-rights.
Reduced value is recorded on the balance sheet for buildings,
equipment and land.  No value is recorded on the balance sheet for
marketable aggregate and decorative stone currently stockpiled.  No
value is recorded on the balance sheet for goodwill. Fixed assets are
recorded at historic cost less depreciation which cloud the true value
of Company assets.

BALANCE SHEET COMPARISONS

For the three-month period ended March 31,2021, there were no
significant changes to the balance sheet.

STATEMENT OF OPERATIONS

Revenues

Gold revenues for the three-month period ending March 31, 2021,
decreased by $74,304 (148%) compared with the same period in 2020 due
to supporting COVID-19 California and federal restrictions, decrease
in the spot price of gold, and the emphasis on maintenance instead of
producing gold.

Expenses

For the three-month period ended March 31, 2021, compared to the same
period in 2020 total operating expenses decreased by $48,015 (53%) to
support COVID-19 California and federal restrictions to support COVID-
19 California and federal restrictions. Operations complied with COVID
19 restrictions. Planned maintenance is less costly than mining.

For the three-month period ended March 31, 2021, compared to the same
period in 2020, the company showed a loss of $66,022 compared to a
loss of $39,733. The $26,289 (66%) difference was due to intentional
changes in the operation from mining for gold to maintenance.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

From time to time the Company makes written and oral forward-looking
statements about matters that involve risks and uncertainties that
could cause actual results to differ materially from projected
results.  Important factors that could cause actual results to differ
materially include, among others:

- Fluctuations in the market prices of gold
- General domestic and international economic, political and
governmental
  conditions
- Unexpected geological conditions or rock stability conditions
  resulting in cave-ins, flooding, rock-bursts or rock slides
- The speculative nature of mineral exploration
- Environmental risks
- Changes in laws and government regulations, including those relating
to taxes
   and the environment
- Fluctuations in interest rates and other adverse financial market
conditions
- Labor relations
- Accidents
- Unusual weather or operating conditions
- Force majeure events

These factors are beyond the Company's ability to control or predict.
Investors are cautioned not to place undue reliance on forward-looking
statements.  The Company will update its forward-looking statements,
whether as a result of receiving new information, the occurrence of
future events or otherwise if significant.

ITEM 4: CONTROLS AND PROCEDURES

Security procedures include multiple levels of gold custody, from the
mine to sales. Inventory control procedures were set up by an SEC
certified auditing firm and continue to be followed.


PART II

Item 1 LEGAL PROCEEDINGS

Company is defending criminal allegations initiated by the California
District Attorney?s Association.

Item 1a RISK FACTORS

(a) Price of Gold

The daily spot price of gold has no financial effect on gross revenue
if it's between $1,700 and $1,800 an ounce. A significant drop below
$1,700 may have an adverse effect on the Company's revenue. Closing
spot price on December 31, 2020, was $1,803.28 and on March 31, 2021,
it was $1691.05 an ounce. The Company's realized gold inventory
usually exceeds the bullion price.


(b) Lack of Proven Reserves

Because proven reserves are not utilized as a component for evaluating
future earnings or ore values, a sense of uncertainty of existence is
perceived by some.  Caution is always recommended in using the
doctrines of reserves as an economic tool for valuing a mining
company. While (i) the Company has recovered over one million ounces
of gold and (ii) management knows that substantial additional virgin
veins exist in the Sixteen to One mine, the Company has no ability to
measure potential gold production using the mathematical tools
generally recognized in the mining industry; however, the company can
prove that approximately seventy percent (70%) of its vein systems
have not been developed.

(c) Governmental Regulation

The attached financial statements have not been audited by a
Securities Exchange Commission (SEC) accounting firm.  Therefore, the
Company is not in full compliance with this SEC regulation for
companies listed on an exchange.

State and federal statutes regulate environmental quality, safety,
exploration procedures, reclamation, employee?s health and safety, use
of explosives, air quality standards, pollution of stream and fresh
water sources, noxious odors, noise, dust, and other environmental
protection controls as well as the rights of adjoining property
owners.  Laws may change preventing or delaying the commencement or
continuance of given operations.

The Company is substantially in compliance with all known safety and
environmental standards and regulations, however; it has faced
reoccurring unreasonable and illegal demands from the Central Valley
Regional Water Quality Control Board (CVRWCB.  The Company expends
working capital and time defending excessive and punitive behavior.
There is no assurance that future changes in the laws, regulations or
reckless interpretations thereof will not have a material adverse
effect. CVRWCB staff accepted invitations to visit the mine property.
A definitive plan is under mutual development to re-write the mine's
discharge permit.

(d) Liquidity

Gold inventory at March 31, 2021, was $279,650 primarily as specimens
or gold held as jewelry.  While history of actual cash sales supports
an inventory value exceeding the spot price, no such increases are
used to compute the inventory.  All inventory of raw material is
recorded at spot price per troy ounce.  In addition, contract
manufacturing costs of jewelry are included in the finished jewelry
inventory.  Periodic shortfalls in liquidity occur which are not
likely to be bridged by institutional debt financing.  Management
addresses these issues as they arise.


(e) Price of Stock

Bids and offers are publicly recorded on the stock page of the
Company's web site and a gray market.  Exposure is limited.  The price
of stock may not accurately reflect its fair market value because of
the limited marketplace and the existence of a wild and free gray
market.  The company deferred programs to support or promote its
stock.

There are conflicting bids, offers and trades between the Company's
website and the unregulated Pink Sheet Gray Market, ticker symbol
OSTO.  Because of these discrepancies the market price is unreliable.

Item 2 UNREGISTERED SALES OF EQUITY

None

Item 3. DEFAULTS ON SECURITIES

None

Item 4. MINE SAFETY DISCLOSURES

For the three-month ended March 31, 2021, the Mine Safety and Health
Administration (MSHA) issued no citations or orders.

Item 5. OTHER INFORMATION

The unaudited interim consolidated financial statements of the Company
are prepared by management in accordance with generally accepted
accounting practices.  Such rules allow the omission of certain
information and footnote disclosures normally included in financial
statements prepared in accordance with generally accepted audited
accounting principles as long as the statements are not misleading.

In the opinion of management, verified by signature below, all
adjustments necessary for a fair presentation of these interim
statements have been included.  These adjustments are of a normal
recurring nature.

The preparation of the Company's financial statements in conformity
with accounting principles accepted in the United States requires
management to make estimates and assumptions.  These estimates and
assumptions affect reported amounts of assets and liabilities and
disclosure of contingent liabilities at the date of financial
statements, as well as reported amounts of revenues and expenses
during the reporting period.  On an ongoing basis, management
evaluates its estimates and assumptions; however, actual amounts may
differ. No accounting principle upon which the Company's financial
status depends, requires estimates of proven and probable reserves
and/or assumptions of future gold prices. Commodity prices may
significantly affect the company's profitability and cash flow.  No
independent accounting firm or auditors have any responsibility for
the accounting and written statements of the Form 10-Q.

The Company and its president assume responsibility for the accuracy
of this filing and certify the financial statements present fairly in
all material respects, the financial position of Original Sixteen to
One Mine, Inc at March 31, 2021.
