Re:       Binding Offer

 

Dear Richard:

 

On behalf of California
Gold Corp. (hereinafter referred to as “California Gold” or “CLGL”), we submit to you the following binding
offer (the “Binding Offer”) for CLGL to acquire an interest in the business and operations of the Aurotellurio project
(“Aurotellurio”) from Mexivada Mining Corp. (the “Company”), the owner of Aurotellurio (the “Acquisition”),
upon the terms and subject to the conditions set forth herein.

 

		I.	California Gold Corp.

 

California Gold, a
U.S. public company whose common stock (the “Common Stock”), is listed on the OTC
Bulletin Board, is pursuing a business strategy in the mining sector in the Americas.

 

California Gold’s
funds, to date, have come from private investors. CLGL expects to return to the capital markets for additional funds to enable
CLGL to pursue its growth strategy, including the Acquisition.

 

		II.	Acquisition Structure

 

CLGL hereby offers
to purchase eighty percent (80.0%) of the assets of the Aurotellurio gold-tellurium property (the “Assets”) through
several payments to the Company of cash and shares of the Company’s Common Stock, subject to the conditions set forth in
Section IV below and the other terms and conditions described herein and assuming the satisfactory completion of our due diligence
on Aurotellurio.

 

For purpose of the
Acquisition, the Assets of Aurotellurio shall encompass (without limitation) Aurotellurio’s entire operations and all related
mineral rights and concessions located in or near Moctezuma, Sonora, Mexico and all related buildings and equipment, if any.

 

    	-1-

    	 

    

 

 

		III.	Payment & Structure 

 

CLGL envisions that
the Acquisition will be structured as a transfer to CLGL of title to eighty percent (80.0%) of the Assets of Aurotellurio, in installments,
upon satisfactory completion of all conditions by CLGL and the Company, as set forth below. To be entitled to these rights, CLGL
shall make the following payments and investments:

 

		a.	Within three weeks of receipt by CLGL from the Company of a signed copy of this Binding Offer letter,
CLGL will pay the Company a deposit of US $20,000, which amount shall be credited to the Company towards its first annual payment
due at Closing. $15,000 of this amount shall be refundable in the event the Acquisition is terminated prior to Closing;

 

		b.	Upon the closing of the Acquisition (the “Closing”), which shall in any event occur
no later than 60 days from signing of a DPA (as defined below), CLGL shall pay the Company a cash payment of US $10,000 (in addition
to the US $20,000 already on deposit) and issue to the Company 250,000 restricted shares of its Common Stock;

 

		c.	Upon the first anniversary of the Closing, CLGL shall pay the Company a cash payment of US $40,000
and issue to the Company 250,000 restricted shares of its Common Stock;

 

		d.	Upon the second anniversary of the Closing, CLGL shall pay the Company a cash payment of US $50,000
and issue to the Company 300,000 restricted shares of its Common Stock;

 

		e.	Upon the third anniversary of the Closing, CLGL shall pay the Company a cash payment of US $70,000
and issue to the Company 350,000 restricted shares of its Common Stock;

 

		f.	Upon the fourth anniversary of the Closing, CLGL shall pay the Company a cash payment of US $100,000
and issue to the Company 500,000 restricted shares of its Common Stock; and

 

		g.	Following the Closing, CLGL shall invest a sum of US $3,000,000 into Aurotellurio over a 48 month
period at a rate of $750,000 per year, for development of the Assets;

 

At the time of completion
of CLGL’s investment of each US $750,000 installment, a twenty percent (20%) interest in the Assets will vest in CLGL and
title to that interest will be transferred to CLGL at that time.

 

CLGL agrees to structure
the Acquisition seeking the most efficient structure from a legal and tax stand point for both the Company and CLGL.

 

		IV.	Conditions Precedent

 

CLGL’s obligation
to complete the Acquisition and purchase the Assets will be subject to the following considerations:

 

		a.	Prior to the Closing, the CLGL shall have completed a financing in which it has raised a minimum
of one million US dollars (US $1,000,000), an amount sufficient to meet its payment obligations under Sections III(a) and (b) and
its first year’s investment obligation under Section III (g) of this Binding Offer;

 

    	-2-

    	 

    

 

		b.	Prior to the Closing, the Company shall have filed all required documents with the appropriate
Mexican authorities, including but not limited to the Mexican Department of Mines, to transfer the Assets to a to-be-organized,
wholly owned subsidiary of the Company (“Newco”) which shall be dedicated solely to the holding of, accounting for
and operation of the Assets. The Company shall use its best efforts to complete the transfer of the Assets to Newco by the earliest
possible date; and

 

		c.	A complete due diligence process as described in Section V below, subject to the CLGL’s satisfaction.

 

		V.	Due Diligence Process & Definitive Agreement Requirements

 

The Company shall afford
CLGL and its attorneys, consultants, advisors, accountants and authorized representatives full access, upon reasonable notice during
normal business hours and at other reasonable times, to all of the Aurotellurio properties, books, contracts, commitments, records,
personnel, lenders, customers and such other materials and information as deemed reasonably necessary by CLGL in order to permit
CLGL to conduct its due diligence investigation. A preliminary due diligence check list may be delivered to the Company promptly
following the execution of this Binding Offer letter.

 

CLGL will complete
its due diligence review of Aurotellurio no later than forty-five (45) days (assuming full cooperation from the Company) from the
date that CLGL receives a signed copy of this Binding Offer letter from the Company (the “Due Diligence Period”), relying
on its professionals, and independent experts, capable of assessing Aurotellurio’s key business-related information (e.g.
technical, financial, commercial, legal and operational). Based on this evaluation, if CLGL determines in its sole judgment that
the Acquisition cannot be pursued, taking into consideration the factors set forth in Section IV above, CLGL will promptly notify
the Company of this fact and shall have the right to terminate this Binding Offer without further obligation, except as otherwise
specified under Sections VII (Confidentiality) and X (Expenses) below. If CLGL determines in its sole judgment that the Acquisition
meets its objectives and investment criteria, CLGL will submit to the Company prior to the end of the Due Diligence Period a written
notification of its intent to proceed with negotiation and drafting of a DPA (defined below).

 

The Closing will be
subject to CLGL’s raising sufficient capital and other factors outside the control of CLGL including, but not limited to,
the parties’ ability to obtain third party consents or regulatory approvals or permits, to the extent required.

 

If CLGL determines
to proceed, a definitive purchase agreement (the “DPA”) based on this Binding Offer shall be negotiated in good faith
and signed by the parties within a reasonable time period. The DPA will contain customary representations, warranties, covenants,
indemnifications and conditions to closing and other terms and conditions as to which the parties may agree including, but not
limited to, the following:

 

		a.	a right of first refusal in favor of each party in the event the other party proposes to sell,
transfer or otherwise dispose of any or all of their interests in the Assets either directly or indirectly; and

 

		b.	a provision whereby the parties agree to form a joint venture for the ongoing exploration and development
of the Assets, such joint venture to contain customary terms and conditions, including a requirement that CLGL fund its share of
exploration and development expenses as scheduled in Section III above.

 

    	-3-

    	 

    

 

		VI.	Exclusivity

 

The Company acknowledges
that it is aware that a significant expense will be incurred by CLGL and its agents in connection with the due diligence examination,
negotiation, preparation and execution of the DPA contemplated herein. In consideration therefor, so long as CLGL is proceeding
with the Acquisition in accordance with the Binding Offer, the Company does hereby warrant, represent and agree that during the
forty-five (45) day Due Diligence Period following the receipt by CLGL of this countersigned Binding Offer letter and, if CLGL
has indicated its intent to proceed as described in Section V, until the DPA is mutually executed and delivered (together, the
“Exclusivity Period”), it will not enter into any agreement or consummate any acquisition with any third party, in
whatever form, with respect to the Acquisition or the Assets of Aurotellurio or otherwise sell, transfer or dispose of any or all
of the Assets or enter into any other transaction that would preclude the consummation of the Acquisition by CLGL, or materially
adversely affect the benefits to CLGL of completing the Acquisition, consistent with the terms set forth in this Binding Offer.
Additionally, CLGL shall have the right, upon notice to the Company, to terminate its obligations hereunder at any time if the
results of its due diligence inquiry are unsatisfactory to CLGL, in CLGL’s sole discretion. The Company represents to CLGL
that it will proceed in good faith to negotiate the DPA, if CLGL shall have indicated its intent to proceed as described in Section
V.

 

		VII.	Confidentiality

 

The Company and CLGL,
and their authorized representatives, shall keep this letter (including any detail included herewith), the Acquisition, any negotiations
or conversations in their regard, and any documents and materials provided in connection therewith, or produced as a result or
on the basis of the materials or documents provided (the “Information”) as strictly confidential for a period
of two years from the signing of this Binding Offer letter. This confidentiality duty shall not apply to the Information which
is publicly available or which is received by a party from another person not bound by a confidentiality duty.

 

		VIII.	Scope

 

The terms and conditions
stated above may not cover all the relevant issues, but shall govern the relationship of the parties during the Exclusivity Period
and shall be superseded by the DPA as negotiated and agreed upon by the parties.

 

The Company agrees
that the eventual Acquisition is subject to internal approvals by CLGL’s Investment Committee and Board of Directors; any
governmental and third party approvals, if necessary; satisfactory legal, tax, business, technical, environmental, accounting and
financial due diligence review and analysis; satisfactory negotiation and execution of all necessary Acquisition agreements (including
the DPA), instruments and other documents relating to all aspects of the Acquisition; closing of a CLGL private placement financing;
and lack of events that occur or would be reasonably likely to occur which would be expected to have a material adverse effect
on the Acquisition, the Company or CLGL.

 

    	-4-

    	 

    

 

		IX.	Term

 

This proposal will
expire on October 12, 2010 if not accepted before then. If the Company is in agreement with the terms outlined in this letter,
please sign and return it at your first convenience. After delivery to CLGL of a signed copy of this Binding Offer letter, its
terms will remain valid and in force for forty-five (45) days from the date of delivery to CLGL or until the DPA is fully executed
by the parties, whichever occurs later, except for Section VII (Confidentiality) and X (Expenses) which shall survive.

 

		X.	Expenses

responsible for its own costs and expenses incurred in connection with the preparation and negotiation of this Non-Binding Offer
letter, the due diligence and the final documentation for the Acquisition.

		C6.	Flight Specifications

 

		C6.1.	Flight Lines

 

Line directions and line spacings are specified
in Schedule B, but may be subject to change and will therefore be confirmed between MPX's and Client's representative
immediately prior to the commencement of the survey operations. Any such changes will not unduly effect efficient collection of
data.

 

		C6.2.	Terrain Clearances

 

Optimum terrain clearances for the helicopter
and instrumentation during normal survey flying are:

 

	Helicopter	 -	70 metres
	Magnetometer	 -	70 metres
	Gamma Spectrometer	 -	70 metres

 

The pilot will make every sensible effort
to fly accurate terrain clearances, however, it is accepted that aircraft terrain clearance may vary, based on the pilot's judgement
of safe flying conditions around man-made structures or in rugged terrain where aviation laws may require a higher flight altitude.
Taking into account the above safety considerations and pilot judgement, MPX will do its best to conduct the survey with an altitude
tolerance of +-20m, trying not to exceed +/- 20m over a distance of more than 1 km.

 

		C6.3.	Airspeed

 

Normal aircraft airspeed will be approximately
70kts, but this may vary in areas of rugged terrain. With a sampling rate of 1 second, spectrometer measurements are acquired approximately
every 36 metres along the survey line. With a sampling rate of 10 times per second, magnetometer measurements are acquired every
3.6 metres along the survey line.

 

		C6.4.	Magnetic Diurnal

 

Flight lines, or portions thereof, will
be reflown if the magnetic diurnal exceeds 12 nT in a straight-line chord over 5 minutes. Survey data acquisition will be stopped
altogether in the case of severe magnetic diurnal activity.

 

		C6.5.	Reflights

 

Reflights will be attempted whenever survey lines or part survey
lines are noted in the field to be beyond the agreed tolerances.

 

The flight lines will not deviate from
the intended flight path by more than 50% of the nominal line spacing over a distance of more than 1 km. All reflights will cross
a minimum of two tie lines.

The magnetic
sensor that will be utilized for the survey is a Scintrex CS-3 high resolution cesium split-beam total-field magnetometer (see
figure 4), which will be installed in a fixed boom. The sampling rate is ten (10) times per second with an in-flight sensitivity
of 0.002 nanoTesla (nT). Aerodynamic magnetometer noise is +/- 0.01 nT. The sensitivity of the magnetometer will be recorded at
0.002 nT when operated at a sampling rate of 0.1 seconds.

 

 

Figure
 4: Scintrex CS-3 Cesium Magnetometer

 

A Cesium vapour
magnetic sensor is a miniature atomic absorption unit, producing a signal whose frequency (Larmor frequency) is proportional to
the intensity of the ambient magnetic field. The unit consists of three main elements; a Cesium vapour lamp, an absorption cell,
and a photosensitive diode.

 

These
components are mounted along a common optical axis within the sensor housing. The electronic support system is mounted at the
rear of the towed bird or 1.5m from the sensor in a fixed boom configuration, transmitting the Larmor signal to a counter in the
data acquisition system then converted the signal to magnetic field strength in nanoTeslas.

Geophysical,
navigation and altimeter data will be recorded by the AGIS data acquisition system in the helicopter, at various recording rates
ranging from 10 Hz to 1 Hz (ten times per second to once per second).

 

Data will be
displayed on the computer LCD display as traces, in simulation of a chart recorder's traces, for verification of functionality
and quality.

 

On completion
of flying, the data recorded will be copied to back-up CD-ROM and transferred to the Field Workstation (described below) where
the data will be retrieved, verified and processed.

 

All geophysical,
positional, and ancillary sensor data measured during the survey are recorded digitally using a high-speed, precision data acquisition
system. Survey data can be monitored on a number of operator-selectable strip-chart traces available on the operators display.
The system does not produce paper charts.

As the magnetic
gradient sensors, installed in the single sensor fixed boom, are still within the magnetic effect of the aircraft structure, tests
will be conducted prior to the survey to determine the effects of helicopter pitch, roll and yaw. The tests will be completed
at high altitude (ideally 10,000 ft above terrain AGL) over an area of low magnetic gradient by carrying out ±10o
rolls, ±5o pitches and ±5o yaw manoeuvres flown over periods of at least 4-5 seconds
in the same direction as the flight and tie lines. A compensation Figure-of-Merit (FOM) for the helicopter will be calculated
by summing the peak-to-peak amplitudes of the twelve magnetic signatures. The FOM is used as an indicator of performance and should
remain below the industry standard value of 2 nT for the sensor mounted in a helicopter stinger/boom.

 

		C8.2.	Magnetic Heading Effect

 

The magnetic
heading effect will be determined prior to the survey by flying a cloverleaf pattern oriented in the same direction as the survey
lines and tie lines at high level in an area with low magnetic gradient. At least two passes in each direction will be flown in
order to obtain sufficient statistical information to estimate the heading error. The heading error will be determined at the
beginning of the survey, and again if there are any modifications or additions to the aircraft or the equipment installed in it.

A lag test
will have been performed before the survey to ascertain the time difference between the instrument readings and the operation
of the GPS System. Test lines are flown in two directions at survey altitude across distinct anomalies.

 

These lag tests
were carried out before the start of survey production flights, and will be repeated after any major survey equipment alteration
or replacement has been made.

Checks of the
radar altimeter calibration will have been undertaken before the survey, after installation of equipment in the aircraft. The
calibration is determined by comparing the radar altitude with a suitable reading from the GPS system during a radar “stack”
over the landing pad or a suitable level area where the height above sea-level (ASL) is accurately known.

 

C8.5. Gamma-Ray
Spectrometry checks and tests 

 

		a.	Altitude
Attenuation Coefficient

Determination
of the altitude attenuation coefficient will have been undertaken prior to the survey by flying a test line at various altitudes
from 60 m up to 250 m at 30 m intervals above the test line. An airborne calibration range test line should have the following
features: (a) Be relatively flat; (b) Have uniform concentrations of K, U, and Th; (c) Be close to a body of water for measurement
of background (if a suitable body of water exists); (d) Be free of flight restrictions; (e) Be easy to navigate; (f) Be about
8 km long, equivalent to about 150 s flying time at 50m/s; (g) Have no hills within about 1 km of the flight line. The results
of this check will be digitally recorded, and will be compiled into tables and graphs to be presented to the Client in
the final report.

 

		b.	Cosmic
Window Calibrations

Cosmic window
calibrations will have been carried out prior to the survey. This is normally performed by flying at various altitudes over the
ocean or any large body of water (250m and from 1,500 m up to 3,500 m at intervals of 300 m), with each altitude flown for a minimum
of 10 minutes. If a large body of water does not exist close to the survey area, this test can be performed over the ground. The
average values of the counts measured in each of the 4 windows (TC, U, Th and K) will be compared against the average counts for
the cosmic window at each of the altitudes where measurements are made. The results of this calibration will be digitally recorded,
and will be compiled into tables and graphs to be presented to the Client in the final report.

		C8.6.	Gamma-Ray Spectrometry
Limitations

 

The presence of powerlines and/or
steep topography may compromise the quality of the radiometric data. We will proceed and try to acquire good radiometric data,
but we will not be able to guarantee the accuracy of data obtained at large heights above the terrain (100m+).  Ideally the
terrain clearance should be maintained at 70m, but topography and safety considerations may be limiting factors for this airborne
survey.  For example, the presence of electrical powerlines forces the pilot to fly at greater heights in order to guarantee
the safety of all personnel onboard.  

 

		C9.	Safety Procedures

 

For the duration
of the work, MPX will ensure that the work performed is carried out with the utmost regard for safety, and that all its
personnel are fully conversant with safety standards considered normal in the aviation industry. MPX’s Project Manager
will review and establish safety procedures with the Pilot and will specifically ensure that all crew members are aware of emergency
and radio communications procedures.

 

During the
course of the Survey, MPX shall keep the site of any refuelling areas free of accumulations of waste materials, rubbish
or garbage and upon completion of the Survey shall remove all tools, fuel, fuel drums, surplus materials, rubbish and garbage
and leave the refuelling sites in a clean condition.

 

The pilots
are ultimately responsible for the safety of each flight but, if at any time anyone in the aircraft has a question about
location, intention, or safety, the pilot must use every effort to address the concerns and resolve the question, without compromising
the safety of the flight. If a crewmember is not satisfied with the pilot’s response or actions the crew member may request
that the pilot terminate the flight and return to the base of operations. The pilot will comply with this request and any disagreement
or discrepancy will be resolved on the ground.

 

The Project
Manager will conduct weekly safety / operations briefings with the crew. These briefings will consist of the following:

QUALITY CONTROL/
DATA PROCESSING

 

		D1.	QUALITY CONTROL

 

Daily quality
control of newly acquired airborne data will be undertaken in the field by MPX’s technologist, and will also be transmitted
on a daily basis via the internet and an ftp-site to MPX’s data processing facility in Markham. Quality control
information may then be confirmed by MPX and relayed back to the field crew on a regular basis.

 

		D2.	DATA PROCESSING

 

		D2.1	Topographic
Base and Title of Survey Area

 

A topographic
base will be prepared for the survey areas from a DTM (or by scanning the relevant topographic maps) covering the survey area,
and plotting the major features (large lakes, major rivers, towns, etc.) as background on to the geophysical maps. All title blocks
and surround data appearing on the base maps will be machine drafted using CAD techniques.

 

		D2.2	Flight
                                                                                                            Path Compilation

 

The flight
path will be derived from the differentially corrected GPS navigation data.

 

		D2.3	Magnetic
                                                                                                            Data

 

The
magnetic data are first corrected for diurnal variations, lag and heading effects. The data will be further analyzed using tie-line
data. Control-line levelling is applied to the tie-line data. Final micro-levelling techniques are then applied to the data to
remove minor residual variations in profile intensities. Located and gridded data are generated for the final processed magnetic
data. 

 

The
semi-automated magnetic data levelling system includes: 

 

		1.	Tabulation
                                                               of magnetic data at flight line/tie line intersections, along with
                                                               flight altitude data;

		2.	Network
                                                               analysis of intersection data, based on minimizing square mean
                                                               root of the differences and closure errors, to obtain suggested
                                                               leveling adjustments;

		3.	Manual analysis of computer
suggested corrections, based on magnetic gradients at the intersections and the flight altitude differences;

		4.	Application of leveling corrections;
and

		5.	Revision of leveling corrections
using imaging techniques.

Any residual,
small scale, in-between tie-line leveling errors are removed using micro-leveling techniques. The resultant gridded magnetic data
will be of high image quality and the corresponding located line data will also be prepared.

 

The regional
International Geomagnetic Reference Field (IGRF) 2011 will be computed (based on 2010 calculated model) and removed from the data
using the GPS location at each observation point and epoch appropriate to the current survey.

 

The total field
magnetic data and residual magnetic data grids will be produced using a minimum curvature algorithm. The reduced-to-the-pole or
reduced-to-the-equator grid will be calculated using the residual grid.

 

The reduced-to-the-pole
or reduced-to-the-equator total field magnetic data may be subjected to a variety of filtering techniques to yield maps and/or
images of the following:

		D2.5.1.	Gridding

 

The
corrected geophysical data from each survey line will be interpolated between survey lines using a random gridding method to yield
x-y grid values for an expected standard grid cell size of 0.25 cm at the mapping scale.

 

		D2.5.2.	Contour
                                                                                  and Colour Images

 

Computer
generated contour images of the aeromagnetic data are created from the grid and will be plotted.

 

Colour
images are produced by interpolating the grid down to an appropriate pixel size. The parameter is then incremented with respect
to specific amplitude ranges to provide solid colour "contour" images. Black-line contours are superimposed on the colour
images. Solid colour images of the total magnetic field are particularly useful in defining the lithology of the survey area.

 

Monochromatic
or colour shadow images can be generated by utilizing an artificial sun to cast shadows on a surface defined by the geophysical
grid. There are many variations in the shadowing technique. These techniques may be applied to total field or enhanced magnetic
data, magnetic derivatives, etc. Of the various magnetic products, the shadow of the enhanced magnetic parameter is particularly
suited for defining geologic structures with crisper images and improved resolution.

A
topographic base will be prepared for the survey areas by either using a DTM, or by digitizing/scanning the major features (large
lakes, major rivers, towns, etc.) from the available topographic maps covering the area, and plotting them as background on to
the geophysical maps. All title blocks and surround data appearing on the base maps will be machine drafted using CAD techniques.

E2.4.1.Daily
Reports

 

Daily
reports will be prepared using an EXCEL spread-sheet format, by the on-site Project Manager, and will be submitted by Fax or E-mail,
daily, to the Client. This report will summarize the details of flights flown, lines acquired, crew details, and information
concerning weather and other relevant matters.

 

E2.4.2.Final
Report

 

On
completion of the data compilation, a draft final report will be delivered to the Client for review and comment. When the
Client’s comments/recommendations, if any, have been incorporated and the revised report accepted (MPX would expect
that this process will take no longer than 7 days), three (3) copies of the report will be delivered to the Client in digital
format, complete with final page-size prints of maps.

SCHEDULE

 IAGSA
SURVEY CONTRACT ANNEX 

1.1 Introduction  

The party contracting
the airborne geophysical survey (Company) and the party supplying the services (Contractor) each has a Duty of Care to ensure
that the survey is carried out safely. The Contractor shall have a Safety Management System and ensure that flight operations
meet or exceed regulatory and Company safety requirements.

 

The provisions contained
herein have been prepared by the International Airborne Geophysics Safety Association (IAGSA) and have been drawn from IAGSA’s
Safety Policy Manual. They represent those provisions normally appropriate to airborne surveys. Additional background and implementation
details may be found in the Safety Policy Manual and the Contractor should reference the manual as necessary.

 

The provisions in this
Annex are not exhaustive and may be amended or extended as necessary in accordance with the survey specific risk assessment.

 

1.2 Job Safety Analysis  

The contractor and where
applicable the aircraft operator will complete a Job Safety Analysis (JSA) for review and acceptance by the Company before awarding
a contract. The JSA should include, but not be limited to, the provisions described in this Annex and IAGSA’s Guide to Risk
Analysis. (Safety Manual Appendix V) Provisions and practices shall be developed and documented to mitigate the effect of identified
hazards.

 

1.3 Survey Height  

Based on pilot reaction
times and other factors, it is generally acknowledged that the lower the survey is flown, the higher the risk associated with
the operation. Current industry practice often dictates low clearance heights. To achieve a safe survey height; the Company will
specify the maximum clearance height possible, consistent with the objectives of the survey to be flown; and the Contractor will
conduct a risk analysis that emphasizes the risk factors which pertain to survey height . These factors shall, as a minimum, include
the following:

 

Terrain relief and elevation
above the trees or the tree canopy

aircraft performance

aircrew flight and duty times

prevailing weather conditions

anticipated density altitude

pilot experience and recency

planned flight speed

1.4 Turning Procedures  

All turns at low-level
should be limited to a maximum angle of bank of 30 degrees and be done at a constant altitude. No climbs or descents should be
carried out during the turn. If the terrain or survey height dictates that a climb is necessary the aircraft should be climbed
to the required height prior to commencing the turn and any descent back to survey height should be done after established in
a wings level attitude.

 

1.5 Minimum Safe Survey Speed
 

The minimum safe survey
speed is to be the greater of: 130% of clean stall speed (Vs); 110% of best single engine rate of climb speed (Vyse, if applicable),
or minimum safe single engine speed (Vsse, if published). This minimum speed shall be observed even when exchanging airspeed for
altitude during a climb and should be raised as necessary to account for local conditions such as turbulence and gusty winds.

 

1.6 Performance Monitoring  

Performance parameters,
including aircraft speed, height above terrain and drape, will be periodically reviewed using data collected during the survey.
Deviations below minimum survey speeds and minimum height will be investigated and corrective action taken to ensure that safety
margins are not compromised. The frequency of review should be such as to identify any discrepancies as early as possible. (IAGSA’s
Technical Committee is working on a protocol that will provide practical guidance for; identifying the kinds of data that should
be available; how often it should be sought; and what to do when hazardous flying is detected or suspected)

 

1.7 Flight Following  

The operator will have
in place for all survey flights a flight following system that includes scheduled position reports, position logs maintained on
the ground, operational flight plans and overdue/emergency response procedures. If the survey is being conducted in an area where
it would be difficult to find a downed aircraft or ground based communication facilities are severely limited the parties should
consider using a satellite based tracking system in conjunction with position reports.

 

1.8 Survival  

In the event that the
aircraft’s survival kit is destroyed in a crash, each crew member carry on his/her person essential survival items that
include a personal locator beacon, means to start a fire, a small knife and a signal mirror.

 

1.9 Underwater Escape Training
 

If the survey is over
water, all crew members shall have undergone underwater escape training at an acceptable training facility during the past three
years. This training should have also cover sea survival and use of emergency equipment.

1.10 Fire Extinguisher Training
 

All crew members, including
equipment operators, shall receive annual training in the use of fire extinguishers in fighting in flight fires.

 

In order to quickly extinguish
any fire in the survey equipment, an appropriate fire extinguisher shall be readily available to the equipment operator.

 

1.11 Monitoring of Radios  

During survey flights
radios are to be turned on and selected to the appropriate ATC or enroute frequencies. Additionally, equipment permitting, common
air to air and emergency (121.5 MHz) frequencies should also be monitored.

 

1.12 Maximum Flight Duration
 

The maximum flight duration
for a single flight shall be five hours (excluding transit time) for a one pilot crew and eight hours (excluding transit time)
for a two pilot crew.

 

1.13 Flight and Duty Times  

The maximum number of
flight hours shall be as follows:

40 hours in any 7 consecutive
day period;

70 hours in any 14 consecutive
day period;

120 hours in any 30 consecutive
day period;

 1200 hours in any
calendar year.

 

The maximum duty time
in any one day shall not exceed 14 hours.

The maximum duty time shall not exceed 60 hours in any 7 consecutive day period.

The pilot shall have a minimum of 2 days rest within a 14 day period. These may be taken separately
or together. If taken separately, one day of rest shall be defined as 30 consecutive hours free of duty.

 

1.14 Fuel  

The pilot shall take all
necessary measures to ensure that any fuel loaded onto the aircraft is not contaminated. (Detailed procedures are outlined in
IAGSA’s Safety Policy Manual).

 

1.15 Use of Helmets  

Use of helmets is to be
considered on a case by case basis and where they are judged to enhance pilot safety, helmets shall be worn.

 

1.16 Night Surveys  

To conduct a night survey
the aircraft must be IFR certified and equipped with at least two independent and dissimilar IFR certified navigation systems
that can be used in the survey area. The survey shall be flown at least 1000 feet above all obstacles within the operational area
and a 10 nautical mile buffer around the operational area. The operational area shall include the maneuvering area for line turns
and lead ins.
